Rank #1: What Exxon Knew and When They Knew It: Climate Science in S.F. Federal Court

Podcast cover
Read more

It’s not a trial, nor is it quite a debate, but what’s happening Wednesday in Judge William Alsup’s federal courtroom is an unusual and possibly unprecedented proceeding. That’s because Alsup has ordered a four-hour tutorial on climate change – what scientists know about global warming, and when they knew it. And it’s because of who’s responsible for the tutorial: Bay Area cities on one side, and oil companies on the other.

The cities sued the oil companies over the impacts of sea level rise, and the tutorial is a key early step in the case, one of dozens of similar cases across the country.

Lawyers for San Francisco and Oakland claim BP, Exxon, Chevron and others created a public nuisance to the Bay Area by producing and selling oil and gas while misleading the public about known consequences. The two Bay Area cases represent one strategy among several in a growing body of law relying on tort and common-law claims to hold fossil fuel producers responsible for global warming.

Complicating these arguments are the other human activities that also contribute to global warming – and the fact that fossil fuel burning is global, which means companies and countries in the oil and gas industry outside of California are responsible.

“And that’s why probably there’s going to be a big focus on the fraud part: who was overtly and aggressively denying the science, who knew internally,” says Stanford University historian of science Robert N. Proctor. “There’s a lot of evidence that some of these fossil fuel makers really did know quite a while ago that there was going to be this threat but they covered it up.”

Proctor says the cases resemble efforts to hold major tobacco producers responsible for smoking-related lung cancer.

“Both of these industries– tobacco and big carbon – have been kind of embracing science and a sense of open inquiry,” he says, “with the idea being that as long as we leave the inquiry open we can maximize uncertainty and say that we don’t really know the truth.”

Alsup has issued a list of questions he wants answered in the presentations. They include the cause of the ice ages, the origins of carbon dioxide in the atmosphere, and even whether billions of peoples’ breathing is warming up the planet.

“These questions are great questions, they’re interesting questions, but they’re not the questions that you would want to say, ‘What’s the state of knowledge?’” says Katherine Mach, a Stanford researcher whose work focuses on assessing climate science. Mach and other scientists characterized the questions as simple, and straightforward.

They’re also pretty easy to answer for scientists. “Turns out answers to those questions are actually pretty well known,” wrote Andrew Dressler, a climate scientist at Texas A&M. Dressler has sketched out his responses on Twitter.

https://twitter.com/AndrewDessler/status/971818482915532800

At the website Real Climate, scientists are compiling and updating crowdsourced responses.

The semi-adversarial nature of the tutorial has reminded some observers of an idea circulated last year, by NYU professor Steven Koonin and then by Environmental Protection Agency Administrator Scott Pruitt, that climate science should be the subject of an intellectual “red team-blue team” exercise, that name taken from military simulations in which one side attacks another. But Wednesday’s briefing is fundamentally different, for at least a few reasons: the judge has wide latitude in using the information presented there, and these days, it’s more likely that the science presented by cities and oil companies will overlap or even agree.

Fossil fuel companies now characterize themselves as active but risk-adverse participants in the global discussion about climate science – and these companies have acknowledged risks posed by climate change in public statements.

ExxonMobil, for example, states on its website that it “unequivocally reject[s] allegations that [it] suppressed climate change research contained in media reports that are inaccurate distortions of [the company’s] nearly 40-year history of climate research.”

But each side has its own time to present the best climate science, and its own version of history. Experts say that format means key differences may emerge in questions around certainty, both past and present.

Cities, for their part, are likely to emphasize growing certainty in climate research.

“What we’ve seen over the last 5-10 years is an incredible amount of research into the science of detection and attribution,” says Aaron Strong, an associate professor of ocean science at the University of Maine. “There are a lot of uncertainties in terms of of future projection of sea level rise, but there’s not a lot of uncertainty in the fact that it’s rising at all.”

Rank #2: The Contentious Future of Point Reyes — Here’s What You Need to Know

Podcast cover
Read more

On a rocky peninsula with sweeping views of the Pacific Ocean, an hour north of San Francisco, cows, tule elk, and people have shared the land for several hundred years — but lately, with growing conflict. That’s why the National Park Service is rethinking how to manage the rangelands in the Point Reyes National Seashore.  

‘Everything is on the table.’Melanie Gunn
Point Reyes National Seashore

President John F. Kennedy established the national park at Point Reyes in 1962, but the government only owned some of the land. The rest had been cattle and dairy land for 100 years. So federal authorities paid out $50 million in the 1960s and 70s to buy the land from the cattle and dairy ranchers. Ranchers were able to stay under long-term leases, and some two million people visit annually, from all over the world.

After an effort to restore tule elk, the herds now roam over the park’s wildlands, as they did before human development nearly drove them to extinction. But they’ve also spread to the ranchlands, becoming a little too free-range for the liking of ranchers, who make their livelihood on public lands. And a bacteria common to dairy and cattle has sickened some of the elk.

These conditions brewed a sour fight among conservationists, the park service, and ranchers, culminating in litigation four years ago.

As a result, the park service now is modifying its General Management Plan, a kind of road map to the next twenty years on rangelands at Point Reyes. In doing that, the park service must consider cutting ranching out of the national seashore altogether. Other ideas for the future include expanding farming and eliminating some of the elk.

“The question we need to resolve through this planning process is whether or not we can have elk and cattle coexisting and what it takes to make it work,” says Dave Press, a National Park Service wildlife ecologist.

Melanie Gunn, a spokeswoman for the seashore, says it’s a public process, “so everything is on the table.” Even the alternatives the public has seen so far aren’t set in stone. “We’re in listening mode,” she says.  

The park service has now released thousands of comments about the park’s future, but the actual planning is only just beginning. Here’s what you need to know to make sense of, or participate in, the process.

Point Reyes is the only national park where tule elk are visible. Tule elk disappeared from the peninsula in the mid-nineteenth century; they didn’t move back until 1978, after the seashore was established. Today the Tomales Point Elk Preserve holds around 450 of them, behind a tall fence on the north side of the seashore.

Elk have spread along the seashore. The fenced preserve was so successful, wildlife managers added a free-range herd in 1998. That second herd has split, with more than a hundred elk hanging out down by Drake’s Estero, and Limantour Road, and a smaller number further north, by Drake’s Beach. Our map shows the range for both free-range herds, based on NPS data.

Cattle fences don’t work on elk. Tule elk are the smallest elk species (of three) in California, but they’re still 600 pounds, and nimble. They can jump a cattle fence easily, to graze the organic grasses ranchers maintain for their grass-fed beef and organic cheese. Ranch fences keep cattle away from some sensitive waterways and wilderness at the seashore. But the only fencing at Point Reyes that controls elk is at the elk preserve, where a three-mile long, ten-foot high, wood-and-wire fence confines the original herd.

A wasting disease has struck elk and cattle out on the Point Reyes peninsula. A bacteria found at Tomales Point decades ago, probably connected to a defunct ranching operation, has caused outbreaks of Johne’s Disease over the years – a contagious, chronic, common, and often fatal sickness in dairy operations. Its symptoms include weight loss and diarrhea for affected animals.

[contextly_sidebar id=”dtU0Yc0WDKONGgcKXeia50w0azAM1epd”]We haven’t fully sleuthed out the disease – in part because no testing is required for it. The park service tests and quarantines elk from the free-range herd, but the last tests for elk in the fenced reserve were a decade ago. The park service says there’s no money for genetic tests for the bacterium that causes the disease, and the test itself can be hard to interpret. Finally, cattle and dairy operations may or may not test for Johne’s in their herds. All that means it’s hard to say with certainty which animals have passed the disease to each other, and when.

Everyone agrees the federal government paid fair market value for land bought from ranchers, but grazing fees may be a different story. Between 1963-1978, the government paid ranching families nearly $50 million for their lands, then allowed them to run dairy and cattle operations on public land under successive 20- and 30-year leases.

Ranchers pay $7 a cow a month to graze on public land. That’s higher than other federal lands, and park management says those fees cover the cost of administering the lands, still, conservationists point out that grazing costs are as much as double on other Marin lands. 

Want to see row crops at Point Reyes? Ranchers do. The word artichoke appears 92 times in the public comments file, and for a reason: the Point Reyes Seashore Ranchers Association is pushing for something called “agricultural diversification.” It would permit pigs, sheep and row crops within park boundaries; interested West Marin residents have weighed in for and against the idea.

And ranchers argue cattle grazing can be beneficial to grassland. David Evans and Claire Herminjard, who manage Marin Sun Farms and Mindful Meats on park service land, say they control the timing and severity of grazing to manage the land.  “Our central love and goal is to make sure that we are doing the best possible job we can, in taking care of the land, the pastures, and all of the layers of ecosystem that are out here, in tandem with our livestock,” Herminjard says, “and our livestock do the best job at being able to keep grasslands viable.”

Environmental groups who sued the National Park Service in 2014 remain skeptical about federal rangeland management at Point Reyes. “From impacts to endangered species, to water pollution, invasive species, soil erosion and conflicts with native wildlife – there’s enough negative impacts from grazing that the park service has to look at them,” says the Center for Biological Diversity’s Jeff Miller. Grazing is a privilege, not a right, say environmental advocates, and the government should take it away if ranching doesn’t meet high standards. “We feel that the general management plan should prioritize the protection of wildlife and habitat, and also it being a resource for visitors,” says Deb Moskowitz, with the Resource Renewal Institute of Mill Valley, “and then see how ranching could possibly fit into that.”

Climate change may mean that the national seashore looks different in 20 years. “We know that we’re going to have sea level rise, average temperature changes, rainfall total changes, distribution of native and non native invasive species, are also going to change,” says Morgan Patton, a fourth-generation Marin resident who runs the Environmental Action Center of West Marin. “We would like to see some discussion about how climate change is going to impact the park’s resources.” NPS ecologist Dave Press says that discussion will happen.

Thirty national parks (out of 417) permit some sort of grazing — and at least one permits agriculture. When the law was passed to create the national park service a hundred years ago, then-Interior Secretary Franklin K. Lane announced that grazing would be permitted in park areas away from visitors, where it wouldn’t interfere with natural resources. During World War I and II, grazing expanded; in western states, operations remain particularly active. And in the Cuyahoga Valley National Park, sustainable row-crop agriculture is managed by a collective.

What happens in Point Reyes will help shape an evolving and communal understanding of what our national parkland is for.

Rank #3: How Much Drinking Water Has California Lost to Oil Industry Waste? No One Knows

Podcast cover
Read more

California survived its historic drought, in large part by using groundwater. It was a lifeline in the Central Valley, where it was the only source of water for many farmers.

California regulators are charged with protecting that groundwater, but for years they failed to do so. Through a series of mistakes and miscommunication, they allowed oil companies to put wastewater into drinking water aquifers that were supposed to be safeguarded.

Now, a KQED investigation reveals that regulators still know little about the actual impact on the state’s groundwater reserves.

One of those errors was discovered by an unlikely person: Bill Samarin, a farmer in California’s San Joaquin Valley.

Oil and agriculture are the big employers in Tulare County, where Samarin lives. Among the citrus and almond orchards, you see steel pumpjacks bobbing above the treetops. So criticizing either of those industries doesn’t make you popular.

“That doesn’t set well with people around here,” Samarin said. “You’re some kind of environmentalist, which isn’t a very accepted thing to be if you’re a farmer out in this area.”

Samarin is not an environmentalist. He describes himself as a “pretty conservative guy.” So what he discovered about the oil industry put him in unfamiliar territory, straining relationships in this tight-knit community.

The Biggest Issue

It started with the oil field not far from his orchard.

‘Is this even possible that they could be taking wastewater and injecting it into drinking water?’Bill Samarin, farmer

“From our house, we could look across and it’s probably about three-quarters of a mile,” he said.

County officials had received an application to expand that oil field and allow more drilling. Given how close it was to his property, Samarin started doing some homework.

“When I looked into it further, I found out actually that the biggest issue out here isn’t the things you see on top of the ground,” he said. “The biggest issue out here is the wastewater and how they’re getting rid of it.”

Oil companies in California produce tons of wastewater. On average, for every barrel of oil, a California oil well produces 19 barrels of water, often laden with salts, trace metals and chemicals like benzene.

“They have to get rid of it somehow and in this area here, they pump it into the ground,” he said.

It’s the standard way in which oil companies dispose of wastewater in California: using injection wells, which are not much more than a pipe going into the ground with a gauge to monitor water pressure.

Generally, the wastewater is deposited pretty deep, below the usable groundwater, into aquifers that are already too salty to be drinkable.

Samarin decided to look up all the wells near his orchard, to see where the wastewater was going. He couldn’t believe what he found.

“I was just stunned, stunned by how close it was to groundwater,” Samarin said. He uses groundwater on his crops, along with a lot of other farmers in the area.

“I just drilled a well here,” he said. “We drilled down to 740 feet. The injection wells in this area are injecting at similar depths.”

Alarmed, Samarin went to the local water regulators, the Central Valley Regional Water Quality Control Board. They told him how a water law, known as the Safe Drinking Water Act, works. Groundwater that’s potentially drinkable is automatically off limits for oil companies for wastewater disposal.

But if groundwater quality is already tainted by oil or salts, then companies can get permission from state agencies and the federal Environmental Protection Agency to put wastewater there.

The regulators gave Samarin a map of the land around his orchard that had been approved for wastewater disposal, as well as the areas that were protected.

Most people probably would have stopped there, but not Samarin. He wanted to know how close those injection wells were to his protected aquifer.

Digging Through the Maps

Samarin didn’t have to turn very far for help. His son, Alex, works with maps for a living.

“I think we’re both curious people,” said the younger Samarin. “Once the question is asked, we want to see what the answer is.”

He plotted coordinates for all the wastewater wells on top of the land approved for wastewater.

“Six out of the seven did fall within the allowable aquifer,” he said. “One was completely outside of it.”

That meant an oil company was putting its wastewater into a protected aquifer that was supposed to be off-limits.

“We were just stunned,” recalls Bill. “It was like: is this even possible that they could be taking wastewater and injecting it into drinking water? Can you imagine that that actually occurs in California in this day and age?”

He decided to take it to county officials.

In 2014, Tulare County held hearings about whether to allow the oil operation near Samarin’s orchard to expand, and he filed an appeal against it.

He wanted the county to know about the mistake: that regulators with the state’s Division of Oil, Gas, and Geothermal Resources had permitted a wastewater well that it shouldn’t have. Over a decade, it had pumped 80 million gallons of wastewater into the aquifer.

At the hearing, Samarin presented his report, going over everything he and his son had found.

“Produced water associated with oil production can contain many constituents that may endanger the environment or the public health,” he testified.

When the meeting was opened for comments, Burton Ellison, a recently-retired regulator with DOGGR, challenged Samarin’s findings, calling them untrue. “Every one of those wells went through a rigorous review,” Ellison told the hearing. “As a matter of fact, I reviewed some of them back in 2008.”

In the end, county supervisors denied Samarin’s appeal, stating that regulating wastewater was the state’s job, not theirs.

Samarin let it drop for the time being. “I left it to other contacts,” he said. “The state water board knew about it.”

‘It looks like a completely broken system.’Briana Mordick, Natural Resources Defense Council

Six months later, those state water regulators reviewing wastewater wells discovered that Samarin had been right.

They ordered the errant injection well that Samarin had found be shut down. The oil company, Modus, Inc., responded that its wastewater didn’t contaminate the aquifer because it had the same salt level as the aquifer it was going into.

What Samarin didn’t know was that his wasn’t an isolated case. It was happening all over California.

“Broken System”

“There are thousands of wells spread all across the state that are potentially impacting clean drinking water,” says Briana Mordick of the Natural Resources Defense Council.

State oil regulators grant permits for wastewater injection wells, so knowing the boundaries between protected and unprotected aquifers is crucial. But for decades, Mordick says, state regulators confused those boundaries.

“It’s just a pretty shocking state of affairs,” says Mordick. “Just poor communication, poor record-keeping. It looks like a completely broken system.”

“Our records weren’t solid,” admits Teresa Schilling, a spokesperson for the division of oil and gas. “They were missing in many cases and it’s essential that we have accurate records.”


In some cases, the aquifer maps were decades old with fuzzy boundaries. In other cases, the records regulators used to make decisions were mixed up 30 years ago. The Environmental Protection Agency had a complete list of the protected aquifers, but for unknown reasons, California oil regulators were working from an incomplete list that didn’t include 11 protected aquifers.

“We understand that the public has concern about what’s at stake with their drinking water,” says Schilling. “We all know we have a right to clean drinking water and we have a right to expect that our government will take care of that for us.”

What regulators are doing now, Schilling says, is reviewing records for thousands of wastewater injection wells, looking for mistakes. So far, about 175 wells have been shut down.

But six years after the problems emerged, there are still hundreds of wastewater wells operating in protected aquifers, mostly in Kern and Tulare counties. Schilling says these aquifers aren’t drinking-water quality and the state is going through the process of approving them for wastewater disposal. That was supposed to happen by February, but the process is still unfinished.

[contextly_sidebar id=”15pcTtN87lI8MC5yd6uoTZdzBsD7cLTU”]“It’s very hard as a government entity to move fast but this has been a top priority at the Department of Conservation,” she says.

Minimal Testing

Still not fully understood is what impact all this has had on the quality of California’s drinking-water aquifers.

“The testing that has been performed has been minimal, I would say,” says John Borkovich of the State Water Resources Control Board.

The agency has tested some of the drinking water wells within a mile of the wastewater wells that were wrongly permitted. The tests looked at the quality of the drinking water.

Borkovich says officials have found no correlation between wastewater injection and “anything we’re finding in the water supply wells.” So far.

“Just because we haven’t seen anything, doesn’t mean there isn’t an issue out there,” he said.

The next, bigger challenge is determining what the long-term impact of wastewater has been on the larger aquifers. Some wastewater wells have been operating for decades.

KQED asked oil regulators for records showing contamination levels of the wastewater that oil companies put into the cleanest aquifers. Officials say they can’t produce those records for KQED, because the information is in stacks of paperwork, spread across several regional offices. They also say the division of oil and gas isn’t looking at that question.

Given how far back the permitting problems go, it could be a challenge for the state to reconstruct what’s happened underground.

“We don’t necessarily have good records of what the quality of that water would have been 20 years ago when they started doing this,” said NRDC’s Mordick. “So trying to figure out whether their actions have impacted the water is really difficult at this point.”

Mordick adds that the state may be overlooking certain chemicals in their testing.

“One of the complicating things is that the state doesn’t require disclosure of most of the stuff that oil and gas operators use,” Mordick says. “Things like drilling fluids, or maintenance fluids, enhanced oil recovery operations, so really, we wouldn’t know what to test for.”

The aquifers in question may not contain groundwater that California needs right now, but future droughts are inevitable.

“Those resources are becoming more and more valuable over time,” says Mordick. “Protecting our groundwater is really important. They need to follow the rules and California needs to step up and take this seriously because they haven’t been for a long time.”

State water regulators say they hope to figure out what the larger impacts have been in the years ahead, but have no set timeline. The risk is that they’ve allowed oil companies to contaminate drinking water aquifers to such an extent that Californians may have permanently lost those sources of fresh water.

Rank #5: ‘Increasingly Unavailable and Unaffordable’: Home Insurance Threatened Amid Wildfire Crisis

Podcast cover
Read more

David Bevacqua never had trouble insuring a home in California, but he was in for a rude surprise after recently buying a house in Bass Lake, in the Sierra Nevada foothills.

“None of the insurance companies would quote me,” he said. “I didn’t know what was going on.”

Bevacqua is not alone. As more and more destructive wildfires have whipped through the state in recent years, Californians living in areas considered a high wildfire risk are seeing their insurance rates creep up  or in cases like Bevacqua’s, having insurers simply pull out of some communities altogether.

Between 2015 and 2016 alone, according to the state insurance commissioner’s office, there was a 15 percent increase in “insurer initiated non-renewals” in fire-prone areas. That means homeowners wanted to keep their insurance but the companies refused to renew their policies.

Since Bevacqua couldn’t get a policy on the “admitted” market, where rates are regulated by the state, he ended up going with an alternative known as the FAIR Plan. Created in the 1960s, it’s a very limited, expensive option-of-last resort for consumers who cannot find insurance elsewhere.

“I’m paying twice as much as I expected, and now I have to deal with three separate policies on this one house,” he said, referring to yet another policy he bought covering earthquakes.

Ah, California.

Stories like Bevacqua’s have caught the attention of policymakers in Sacramento, who have made a number of tweaks to laws governing personal property insurance in recent years, including legislation prohibiting insurers from canceling policies after a home burns down, and laws aimed at making sure people understand their policies and are not underinsured.

But more sweeping insurance reforms have died under pressure from the insurance industry, and as of yet, no one seems to be ready to completely overhaul the state’s insurance market. According to the industry, 98 percent of Californians with home insurance are still covered by the traditional, regulated market, with the other 2% using the FAIR Plan and other policies not regulated by the state.

“The reason I hesitate about rethinking the entire insurance industry is that in California — despite these fires, despite the challenges — we have a robust market,” said California Insurance Commissioner Ricardo Lara. “We still feel comfortable that our insurance market is strong and healthy enough to be able to pay out claims.”

Mark Sektnan, of the American Property Casualty Insurance Association, agrees.

“Overall we still see the market as very competitive, very viable,” he said. “But we do understand that homeowners in certain areas may be facing challenges.”

‘Increasingly Unavailable and Unaffordable’

California actually has some of the most consumer-friendly insurance laws in the nation, thanks to a 30-year-old ballot measure that set the rules still in effect today.

Those rules require insurance companies participating in the regulated market to base insurance rates on a customer’s individual level of risk.

And while the state insurance commissioner must approve the amount insurers can charge, he can’t force them to offer insurance if they think the risk is too high.

Those restrictions make sense, Lara said, to ensure that the insurance market stays financially healthy. So while he is concerned about the cost and availability of insurance in wildfire-prone areas, he said that basing prices on the level of risk that a home poses makes sense, even if it is driving up costs for those who are the most vulnerable.

The Commission on Catastrophic Wildfire Cost and Recovery,  set up by the state Legislature and governor to study wildfire costs, agreed with Lara, warning that if California “artificially masks” expensive insurance in high-risk regions by subsidizing rates, it will incentivize risky behavior and make insurance more expensive for people in other parts of the state where wildfires are not a threat.

Still, the commission’s recent report said that while “the home insurance market is not in crisis yet,” the state is “marching toward a future where home insurance will be increasingly unavailable and/or unaffordable” for Californians in high-risk fire areas.

The commission focused on areas known as the wildland urban interface, or WUI, which refers to regions where homes are built near forests or other wildlands threatened by wildfire.

“In evaluating whether to subsidize homeowners insurance in the WUI, policymakers need to consider whether the state wants to encourage more people to move into the WUI,” the report states. “We believe doing so will lead to more deaths and injuries of both residents and first responders, destruction of property, loss of homes, more damages to be paid by utilities …  consequent costs to shareholders and utility ratepayers, and more costs for local, state and federal governments and taxpayers.”

Discounts for Clearing Brush?

Consumer advocate Amy Bach, executive director of the insurance consumer group United Policyholders, agrees that the current risk-based system should not be changed.

That’s because at its core, she says, insurance is “basically just a very kind of informed gambling.”

“When you buy insurance, you’re basically transferring your risk onto the insurance company,” she said. “The insurance company looks at you and says, ‘OK what is this person’s risk profile? How old are they? How responsible are they? What’s their history? … ‘ They’re just deciding, what is this risk worth that I’m taking on, and what am I going to charge this person?”

Lara, the insurance commissioner, said he is trying to figure out how to “incentivize more of the admitted market insurers to stay in” high-risk areas to ensure lower prices and consumer protections.

“I know that’s a lot to ask in some of these communities,” he said.

But he noted that California is the largest market in the country.

“It is a massive market for the insurance companies. I don’t think it behooves them to leave the market. But also we have to figure out how we learn to coexist and how do we ensure that the market is robust so that they can pay out the claims and we can continue with our daily lives.”

One way to do that could be requiring insurance companies to offer lower prices to individuals and communities that invest in materials and initiatives that make them less vulnerable to fire. That could include clearing the area around a home of dangerous brush that can ignite during a wildfire, or building homes with more fire-resistant materials.

Lara said his office is pushing insurance companies to consider those sorts of discounts, similar to the discounts they give good drivers, for example. He said the industry is open to the concept.

The industry is indeed exploring the idea, says Mark Sektnan, of the American Property Casualty Insurance Association. But to make it work, companies would need entire communities to participate in reducing a wildfire threat, because fires come with a uniquely unfortunate risk compared to other natural disasters.

“If you mitigate your house for a hurricane or earthquake — whatever you do for your house directly benefits you, whatever your neighbors don’t do, doesn’t negatively impact you,” Sektnan said.  “Wildfire is the one catastrophe where you may take all the correct actions, but if none of your neighbors do, the effectiveness of your own mitigations are not as good.”

Sektnan said this kind of communitywide approach is already being taken in at least one market, where the county of Boulder in Colorado is partnering with insurers to bring down everyone’s rates.

Lara agreed that collective action is key, saying the state now needs to think about how to ensure communities work together to harden themselves against wildfire.

He also wants to simplify insurance contracts so that consumers have a better idea of their coverage ahead of a disaster.

“How do we create smarter contracts so that people can clearly understand what they’re covered [for], what they’re paying?” he said.

Climate Questions Loom

Of course, personal property insurance isn’t the only insurance question looming over California, as climate change is not only making wildfires more destructive, but it’s raising broader questions about the state’s resilience.

For one, state firefighting costs have exploded in recent years, so Lara is pushing legislation that would let the state take out insurance to cover those cost overruns.

State leaders are also debating the possibility of a multibillion dollar wildfire insurance fund that would help protect the state’s utilities against financial ruin when they’re found liable for fires.

And Lara is also exploring more out-of-the-box ideas, such as taking out insurance policies on natural resource like wetlands or forests that are threatened by climate change but whose existence actually helps mitigate its effects.

Lara, a former state lawmaker, authored legislation in 2018 to create a working group to address the broader question of climate change and insurance; that group will start meeting soon.

“Where are we most vulnerable as a state? Where are we most at risk? ” he said. “We know, for example in the Bay Area, the wetlands around the bay are critical, and we have to make sure that they’re strong and they’re thriving so that we could defend against potential flooding or sea level rise.”

In other parts of the world, this is already happening. For example, a coral reef off the coast of Cancun, Mexico, was recently insured in a collaboration between the government and nongovernmental organizations.

“The world’s already starting to figure out how do we bring in the insurance industry in our united front against climate change,” Lara said.

Now, California must do the same.

Rank #6: On the Fourth of July 20 Years Ago, NASA Landed the First Rover on Mars

Podcast cover
Read more

On July 4th, 1997 as Americans were stoking their barbecues, a NASA spacecraft touched down on Mars and bounced like a beach ball. The Pathfinder mission was an unlikely and stunning success that marked the beginning of a roaming robotic presence on the red planet.

The successful feat surprised everyone—including the team behind the mission, a mission that didn’t have the best reputation in the beginning.

Jennifer Trosper applied to work at NASA in the nineties. “And I got a phone call,” Trosper says. “He [the recruiter] said, ‘Well, we got this project out here. Nobody really wants to work on it, because nobody thinks it’s going to work.’”

NASA was trying something new: space travel for a bargain price. Pathfinder’s mantra was cheaper, faster, better. The goal was to cut down on red tape and dream of solutions no one had else had thought of.

“Be crazy and bold and innovative,” says Pathfinder’s chief engineer Rob Manning.

‘Cheaper, Faster, Better’

When Trosper arrived in Los Angeles, she joined a team of scrappy aerospace engineers at the Jet Propulsion Laboratory (JPL) willing to work on a lean budget and try something revolutionary.

“We didn’t follow all the rules. We had some good leadership, but it was a very small team,” Trosper says, “And we were landing on the surface of Mars with air bags!”

The airbags were designed to cushion Pathfinder’s landing. Touching down on Mars can be tricky because the atmosphere is so thin. That’s one reason no other country had had a successful landing for twenty years. NASA’s last success was the Viking 1 and Viking 2 orbiter-lander in 1975.

Low Budget Inspires Innovation

Manning says the team settled on a parachute to slow the spacecraft down as it hurtled through the Martian atmosphere. The engineers also wrapped the machine in a cocoon to protect it when it touched down on the rocky landscape—kind of like a beach ball.

[contextly_sidebar id=”ydG3BtuLQBhWZAiZ4ojhjUkOgqckWcSE”]Manning says the idea was that the ball “would bounce and roll on the surface. And finally open up like a flower and have a little rover drive off.”

If successful, the tiny rover—about the size of a microwave—would become the first wheeled vehicle to explore the surface of another planet. NASA named it Sojourner.

Seven months after the launch, NASA engineers monitored the spacecraft’s status as it neared its icy destination. A nervous tension filled the control room at JPL. And then at the exact moment Pathfinder was expected to bounce down, a faint signal sounded, back on Earth. The room erupted with loud applause and cheering.

“By late afternoon for us we were getting our first picture,” Manning says, smiling.

Miraculously, Pathfinder had traveled millions of miles and landed upright on the red planet.

NASA uploaded the images to a new realm known as the World Wide Web. Jon Brooks, a science editor at KQED, remembers the moment vividly.

“You could see a little more, a little more, a little more,” Brooks says, “and the anticipation was truly great because you were going to catch a glimpse of Mars for the first time. You actually saw the barren landscape and the red color.”

The Most Important Question

Sojourner was expected to take pictures for one week before its batteries died. Instead, the little spacecraft weathered the frigid climate for nearly three months. Pathfinder beamed thousands of pictures back to Earth, says Manning, to help his team answer one central question:

“Was Mars at some point in its past a place with lakes and an atmosphere and places where presumably life could actually get started?”

The quest to find an answer has inspired three more NASA rovers after Pathfinder. The latest, Curiosity, is the size of an SUV and has been driving around Mars for nearly five years looking for clues about how and when the red planet went from warm and wet to cold and dry.

Astronomers are still searching for signs of life, but they have confirmed the presence of water. Observations suggest that habitable lakes and streams likely existed in the ancient past.

“Doesn’t say anything about whether there was life there,” Manning says. “But it does say this planet is much more interesting than we ever dreamed.”

Mars is the only planet inhabited solely by robots (as far as we know). Next year the U.S. will send the InSight lander to Mars, and the Mars 2020 will follow. NASA hopes to land a human on the red planet within the next twenty years.

Rank #7: California Has Farmers Growing Weeds. Why? To Capture Carbon

Podcast cover
Read more

California’s climate change efforts can be spotted all over the Bay Area in the growing number of electric cars and solar panels. But now, California is enlisting people from a more conservative part of the state — even if they don’t think climate change is much of a concern.

California’s farmers are receiving millions of dollars to pull carbon out of the atmosphere, something the state says is crucial for meeting its ambitious climate goals.

The state is paying them to grow plants, which absorb carbon and help move it into the soil where it can be stored long-term. That makes California home to some of the first official “carbon farmers” in the country.

For some, like almond grower Jose Robles of Modesto, climate change was an afterthought, if that. That’s something they talk about in Sacramento, he says, not where he lives and works.

But in December, the ground under Robles’ almond trees was a carpet of green, full of mustard plant and clover. It’s not a common sight in the Central Valley. After all, most farmers hate weeds.

“Everybody wants to have the orchards nice and clean,” Robles says, laughing.

His neighbors really don’t understand it.

“I’ve heard them say, ‘We’re in the business of growing almonds, not in the business of growing weeds,’” he says, laughing.

Adapting to Drought

Robles got the idea a few years ago, during California’s severe drought, when he had to cut back on watering his trees.

“We had no water,” he says. “It made us look at things different.”

Robles knew that richer earth with more microorganisms holds moisture longer, but there wasn’t a lot of organic matter in his orchard to build the soil up. Like most farmers, he sprayed herbicides to kill weeds.

So he decided to grow organic matter specifically to feed his soil. He planted species that most people commonly see as weeds, but when sown on purpose, are known as a “cover crop.”

Once they get a few feet tall, he mows them and lets them decompose, along with some extra compost and mulch. A $21,000 grant from California helps cover his extra costs and labor.

It can be tricky, because almonds are harvested from the ground after they’re shaken off the trees. Having mulch or weed remnants on the ground would interfere with that, so Robles has to make sure the organic matter breaks down before harvest begins.

He’s already seen a difference.

“The trees, they don’t stress as much, because they hold the moisture a lot longer,” Robles says.

Absorbing Carbon Emissions

Though climate change didn’t really factor into Robles’ decision, his grant comes from a program designed to be part of the state’s climate change strategy. California’s Healthy Soils initiative is now in its third year.

Farms and forests could absorb as much as 20 percent of California’s current level of emissions, says a state report.

“I think there’s great potential for agriculture to play a really important role,” says Kate Scow, professor of soil microbial ecology at UC Davis, of the state’s climate goals. She’s standing in a large wheat field at Russell Ranch, seven miles west of the campus, where the university plants crops to study sustainable agriculture.

“Soil is alive,” she says. “There’s farmers that know that.”

To show me, Scow starts enthusiastically digging in the dirt.

“All right, see, we’re starting to hit the mineral soil.”

This is where the carbon is stored. Plants soak up the carbon dioxide in the air to build their leaves and stems. Their roots pump carbon down into the earth. Then, when the plant dies, its organic matter gets broken down by microbes and fungi. That’s how carbon from the air gets into the soil.

“The deeper you can get it in the soil, especially below the plow layer, the more stable and secure it’s going to be,” she says.

That’s key to prevent the carbon from being released back into the air, and is how agriculture could play a part in the state’s climate effort.

“We have very ambitious climate goals, and without natural and working lands, California simply won’t get there,” says Jeanne Merrill, with the California Climate & Agriculture Network, a coalition of ag groups working on climate policy.

Before leaving office, Gov. Jerry Brown set a goal for California to be carbon neutral by 2045. That will likely mean not just reducing carbon emissions from cars and buildings, but absorbing carbon already in the air.

Merrill says California’s farmers are already on the frontlines of facing climate impacts, like more extreme weather.

“Some are willing to say that it’s climate change,” she says. “Others are unsure. But I think many know that things are changing and they need different tools.”

Farmers are interested in the climate programs, Merrill says, if only because it can help them weather extended droughts.

Hundreds have signed up. But state climate officials say the Healthy Soils program needs to be five times larger. That means the state Legislature will have to boost its $15 million budget, and Gov. Gavin Newsom has requested more money for the program. (Update May 9, 2019:  In the May revise of the state budget, Newsom has proposed $28 million for Healthy Soils, an increase of $10 million over his original proposal.)

Merrill says that would send a signal that California’s climate efforts will take the entire state, not just coastal cities.

“It’s bridging that coastal-Valley divide,” she says. “It’s saying that we need that Valley base pretty significantly.”

Rank #8: You Know About This Summer’s Spectacular Solar Eclipse, Right?

Podcast cover
Read more

Save the date: August 21st. On that Monday, across the United States, millions of people will be granted a rare chance to see a total solar eclipse. The last time a total solar eclipse crossed the contiguous U.S., Jimmy Carter was president (1979). It has been nearly a century since an eclipse swept the country from coast to coast (1918).

“It’s not often that celestial events favor our own country in such a way,” says Seth Shostak, senior astronomer at the SETI Institute. “And this gives the opportunity to a lot of people to see something that really shouldn’t be missed.”

The eclipse will first be visible by land at Lincoln Beach, Oregon. At 8:04 a.m. the moon will begin to edge in on the sun, taking a tiny chip out of it.

Eclipses are possible thanks to a happy coincidence: The Sun is 400 times the diameter of the moon, while also being 400 times farther away from Earth. To us, both the moon and the Sun appear to be the same size allowing the moon to block light from the sun during solar eclipses.

As the 70 million million million metric tons of rock that we know as our moon slide across the solar disc, darkness will descend, sweeping in from the west. The temperature will drop. Birds may cease singing, squirrels may give up their foraging. The stars will come out.

Observers of past eclipses say life seems suspended in animation, as the shadow of the moon sweeps over them. Looking up they see a “hole in the sky” surrounded by flowing flames. Or, “a black sunflower with the most delicate of silver petals,” as Frank Close writes in Eclipse: Journeys to the Dark Side of the Moon.

These ‘petals’ are the sun’s corona. Curiously, this outer atmosphere of the sun is far, far hotter (up to 450 times hotter) than the surface of the sun. But why this is so is still a mystery.

The stage where the corona is visible to the naked eye is the moment of total eclipse, called “totality.” You will see the total eclipse only if you are inside the 50-mile wide band marked out on the map below, a path that will sweep across the country stretching from just west of Salem, Oregon to Charleston, South Carolina. (Check out the Eclipse Megamovie Project, a joint project of Google and UC Berkeley. Type a  location into their simulator to see what the eclipse will look like from there.)

https://www.youtube.com/watch?v=zgZnha_S9BQ

A word on safety: Don’t look directly at the sun. Ever.

For the first hour of the eclipse, the moon with be sliding over the disc of the sun taking, as Shostak says, “bigger and bigger cookie bites.”

Even if it is partially blocked, if you look into the sun it may be the last thing you’ll ever see. You can, however, watch with eclipse glasses, which are equipped with protective film. Or, cut a hole in a piece of paper or cardboard and project the eclipse onto a surface, such as the ground or a wall. Once the moon has completely blocked out the sun (during totality) it is okay to look up. In fact, don’t miss looking up! You can even take a peek through your binoculars or telescope.

https://dts.podtrac.com/redirect.mp3/www.kqed.org/.stream/mp3splice/radio/science/2017/06/Eclipse_170619.mp3

Shostak recommends Oregon as the most practical locale for Californians to view the eclipse, if they’re willing to travel. “You might think ‘Gosh! That’s a long trip for two minutes of celestial fireworks,'” says Shostak. “But I can assure you, seeing the moon get in front of the sun is something you will always remember.”

Rank #9: Californians Will Ski on the Fourth of July

Podcast cover
Read more

You can celebrate America’s birthday in the surf or the snow this year.

Two California ski resorts are still open. It is the fourth time Squaw Valley Alpine Meadows has had enough snow for Fourth of July turns since the resort opened in 1949. Mammoth Mountain predicts there may be enough snow to stay open through August.

‘It’s a little like water skiing. But it’s great coverage so you can’t complain.’Michael Visconti

On a recent 80-degree Sunday, a stream of skiers and snowboarders in board shorts and tank tops tumbled out of the gondola at Squaw Valley. Nearby, a waterfall poured through a gap in the cliffs as the hot skies penetrated the snow.

Clearly the bluebird skies are the highlight rather than the conditions. Skiers say the wet snow feels like gooey oatmeal, mashed potatoes or ice cream.

As San Francisco resident Michael Visconti carved turns in the slush, a fan of water sprayed out from underneath his skis. “It’s a little like water skiing. But it’s great coverage so you can’t complain.”

Bikinis and Costumes

Peopled posed for photos on the slopes with Lake Tahoe’s turquoise waters glimmering in the distance. Women were dressed in slinky bikinis, black lingerie and red booty shorts, yet it was Visconti’s outfit that stole the show.

“I’ve got my signature zebra pants,” said Visconti. “I’ve got this monster hat with light up eyes and pink fur. It seems to be incredibly popular with the five-year-old crowd who want to know what kind of monster I am.”

Dangerous Waters

All the liquid running off the mountain has lifted water levels in Lake Tahoe to capacity. Water managers are releasing as much runoff as possible through the Lake Tahoe Dam at the mouth of the Truckee River. Usually the upper river is knee-deep flat water that families raft in inner tubes, but it’s currently a frothy beast closed for swimming.

“It’s too high to be rafting right now,” said local raft guide Richard Saffo. “The bridges, you can’t go under them. So it’s very dangerous. Whether it’s decapitation or a gnarly concussion — either will definitely ruin your vacation.”

Tributary Waters, the company Saffo works for, offers trips down a safer section of the Truckee River closer to Reno. This year Saffo warns his clients to hold on tight because if they fall in they could spend a long time in the icy waters.

“Those rapids come alive,” said Saffo. “The water is so high and swift you might swim for two miles.”

In fact it could be lethal. The Associated Press is reporting that western rivers have claimed at least 14 lives so far this year.

From the Mountain to the Sea

Fresh water from the Sierra is rushing all the way across the Central Valley and pouring into the San Francisco Bay. The runoff is so powerful, it’s pushing back the salty ocean water all the way to the Golden Gate Bridge, which is much different than what happened during California’s recent drought when runoff barely trickled into the Bay.

Even though the snowpack on April first was 164 percent of normal and the winter was one of the state’s wettest on record, it wasn’t as cold as previous generations. Jeffrey Mount, a water expert for the Public Policy Institute of California, says that’s a sign of climate change. [contextly_sidebar id=”vpkwyaXJlYR183eqwbwy3AvUlU0Ufxp5″]

“What we forget is this year is still part of our long term trend that started back in the early 1980’s — warmer than average winters,” said Mount. “So as we continue to warm, there’s a lot of consequences.”

Warmer temperatures mean melting snow evaporates quicker, trees bloom earlier and soils dry up faster. Though Mount says that doesn’t add up to another drought — at least not in the near term. He cautiously predicts California is likely to have another snowy winter because wet years tend to cluster together. Though he says he wouldn’t put money on it.

Rank #10: A Glimpse Into the Future of Northern California Plant Life

Podcast cover
Read more

Imagine what a Northern California garden might look like 100 years from now as temperatures keep rising. Where lush grasses, riotously bright California poppies and quaking aspens once stood, picture — what? Cracked earth, tumbleweeds, cactus and giant cockroaches, maybe?

A group of artists and scientists at UC Santa Cruz (UCSC) have a different vision for the California landscape of the future, and they’re starting to prepare for it now.

Part science experiment and part art installation, “Future Garden for the Central Coast of California” aims to discover which plants are most likely to survive escalating temperatures and can help regenerate the regional ecosystem as climates shift.

There are 16 different species of plants in each of the three restored, 1970s-era geodesic domes at the UCSC Arboretum and Botanic Garden. The plan is to accelerate the process of climate change inside the domes to find out which species are more resilient over time.

The process is going to take a while;  the recently-installed project is expected to last 50 to 75 years.

“We’re assisting the migration of species through time,” says Santa Cruz-based environmental artist Newton Harrison, who co-created the project with his late wife Helen Mayer Harrison and other science and art partners at UCSC.

The world-renowned artists, who in 2016 became the subject of a beautifully-illustrated tome published by Random House, and whose archives are housed at Stanford University, have been making environmental artworks on a global scale since 1969. The Harrisons’ work mostly takes the form of installations, writings and large-format wall maps. And it has brought them both fame and notoriety over the years.

One the one hand, they inspired a branch of the Dutch government to change its approach to urban planning as a result of their Green Heart of Holland project; on the other, they caused political uproar in England during an exhibition at London’s Hayward Gallery involving the electrocution of catfish. (The controversy was later transformed into a chamber opera.) You can read and listen to a KQED profile of the Harrisons and their epic career here.  

The inspiration for this latest project at the UCSC Arboretum came more than two years ago, when the Harrisons happened to stroll past the three, then-decrepit domes and saw an opportunity to renovate and convert them into testing grounds for local plants facing the effects of climate change. “Nature is pretty opportunistic,” Harrison says. “And artists are pretty opportunistic, too.”

“Two of the domes had been completely shut off and empty and one of them was being used for a crafting group,” says Martin Quigley, executive director of the UCSC Arboretum and the Harrisons’ main collaborator on the project. “All of them were in very bad repair. So this has revitalized the whole area.”

There’s new fabric on the domes, and a fresh, stable framework, plus new landscaping all around the area.

Each Future Garden dome houses an assortment of 16 native plants, chosen chiefly for their likely resilience in the face of sudden, drastic temperature and water fluctuations. Species on display include yarrow, fescue and coyote mint. Some of the plants are edible. Some have medicinal properties. Many have also been a staple of Native American life in the region for thousands of years.

After a year of establishing the plants, the project team members plan to start playing with the conditions inside each dome. One dome will experience heat spikes in summer months and less than normal rain during the winter, similar to a continental desert. One dome will mimic coastal temperate conditions in the Pacific northwest, with ambient temperatures and summer rainfall. The third dome will experience both heat and water spikes amid warmer than average temperatures, mimicking subtropical conditions.

Outside the domes, the same species have been planted in small walled gardens around each dome to provide a set of control experiments.

“Climate change isn’t about a slow steady temperature increase,” says Quigley. “It’s about spikes and randomness that increase. And because these domes are smallish, it’s very easy to manipulate that in a strong way.”

Future Garden is part of a larger, ongoing investigation by the Harrisons into the survival of species in the face of climate change, entitled The Force Majeure. The Harrisons co-opted the legal term “force majeure” for this body of work, which means a huge power that cannot be controlled, not unlike the fast-encroaching water levels and rising temperatures we’re experiencing on the planet today.

Another Force Majeure project, at the University of California Berkeley’s Sagehen Creek Field Station in the Eastern Sierra Nevada, is already starting to see results. For the four-year-old installation, artists collaborated with field station scientists to physically move groups of plant species to different altitude levels. The aim is to help seedlings — such as wild rose and red fir — become resilient to the warming effects of climate change.

“We found something rather astonishing, after drought and all the other problems it could possibly have,” says Harrison. “Of the 21 species we installed, about six — or 25 percent — live at all levels. That’s success.”

Although he has reason to be mildly optimistic, Harrison continues to worry about what our hot, dry future might look like. And though it’s a controversial idea, he believes finding a way to help a few, hardy species learn to become more adaptable to rising temperatures is ultimately more likely to succeed than trying to save many already-endangered species from dying out.

“An awful lot of the experimentation that receives grants aims to save the most endangered species, which if the temperature gets hot enough, are not inherently savable,” Harrison says. “We take exactly the opposite position. We look for the most resilient species.”

“Future Garden for the Central Coast of California” is presented by UCSC’s Institute of the Arts and Sciences.

Rank #11: Why California’s Best Strategy Against Wildfire Is Hardly Ever Used

Podcast cover
Read more

With climate change, wildfires threaten disaster and chaos in more California communities, more often. But experts say it’s possible to avoid catastrophic harm to human and forest health by setting planned burns before human error, lightning or arson choose when fires start.

[contextly_sidebar id=”jxcGO35mXk1KJYVaQ7fcALHMXXhgpY5X”]“Putting prescribed fire back out on the landscape at a pace and scale to get real work done and to actually make a difference is a high priority,” says Cal Fire chief Ken Pimlott. “It really is, and it’s going to take a lot of effort.”

‘Unprecedented Catastrophe’

In a February report, the watchdog Little Hoover Commission concluded that the way California landowners have collectively managed forests is an “unprecedented catastrophe.” In May, Gov. Jerry Brown issued an executive order to improve forest management, and with it, a dramatic change.

Now Pimlott says that Cal Fire intends to triple the amount of prescribed fire on lands the state controls.

“We can prevent these large catastrophic fires or at least reduce the intensity when fires do occur,” he says. “So a little bit of smoke now and a little bit of inconvenience now is well worth offsetting these large damaging fires.”

That’s a small step toward addressing a major deficit. According to the commission’s report, an area the size of Maryland—including state, private and federal land—needs maintenance or planned fire to become healthier.

‘We can prevent these large catastrophic fires or at least reduce the intensity…’Ken Pimlott, CalFire Chief

One day of prescribed burning in the Tahoe National Forest offers a glimpse of the difficulties in completing these projects.

Easier Said Than Done

U.S. Forest Service wildland firefighters hacked a line into the earth, around a patch of land on the Yuba River District near Pendola, overlooking Bullard’s Bar for one day of work. A “hot shot” crew and crew members from two engine companies gathered for the day’s work.

“This day started a few years back,” Jennifer Hinckley laughs dryly. Hinckley is a fire and fuels specialist for the Tahoe National Forest. And she does a lot of paperwork: before the first torch even can drip fire on the ground, federal law requires extensive environmental review.

Even with approval, federal wildland managers waited months for the right weather and environmental conditions here. Hinckley says those criteria range from wind speed and temperature, to how much water is in the soil. It was a very wet spring; on-and-off rains created several months of delay here.

Thick vegetation in the understory is a limiting factor, too. Hinckley says her crews often need to chop and flatten vegetation to make safe conditions for burning.

Even when all of the stars align, Hinckley says she might not have warm bodies for the job. That happened last fall, when fires up and down the state kept fire crews hamstrung.

“I didn’t have crews to perform prescribed burns,” she says, “because the wildfires take priority.”

Even when the permit is done and the weather is right and crews are available, the air might already be too polluted to add more smoke to the mix. Air regulators grant permission for burn days, and it’s hard to get: regional atmospheric conditions mean that smoke from Sierra Nevada forests funnels toward the central valley, where air pollution is consistently bad.

Balancing Forest and Human Health

Whether from wildfire or planned burn, smoke feels like pollution to vulnerable lungs.

“The consequences are the same in terms of patient response,” says Fresno-based asthma and allergy specialist Praveen Budigga. “I mean, patients are going to have the same effects of the fire.”

State and regional air boards say they’re working to balance forest and human health.

“We have to protect public health; that’s our mandate,” says Dar Mims, a meteorologist with the California Air Resources Board. “But we also recognize that we need burning in the forest, and a lot of those trade-offs have to happen in real time because the decisions have to be made—do we want to potentially impact the air basin, or do we want to burn.”

’We have to protect public health. That’s our mandate.’Dar Mims, CARB

Air regulators and fire officials say that to promote prescribed burns will require better public education about their relative hazards. Last year, a groundbreaking study concluded that wildfire smoke contains three times as much pollution as smoke from prescribed fires.

CalFire’s Ken Pimlott says that’s reason to push for more burn days.

“We want the ability to have some more flexibility to be able to burn on days [when] maybe it’s not quite as close to an air quality attainment day as one would like but it’s a perfect prescription window,” he says. “Say we have the resources available and the temperatures and humidities and wind—all of those, vegetation, are all in alignment to make a perfect burn and so we want the ability have a little flexibility.”

Bringing Fire to a Healthier Landscape

Evidence of the ecological benefits of fire are visible at the Bouverie Preserve, a wildland area in Sonoma County. Beginning in spring, a living carpet of purple lupine, white popcornflower, yellow fiddleneck unrolled across the preserve’s fields and canyons.

“It’s lush and green with wildflowers. It’s pretty beautiful,” says fire ecologist Sasha Berleman. To her, this off-the-charts growth signals a healthy landscape, where wildflowers followed the fire in short order.

But look closer at the trees, she says, pointing out how the heat of the Nuns fire blackened the ground and charred the oaks, their trunks scarred with flames up to six feet high. Berleman wonders whether the fire needed to be that severe.

“With that wind event that we had, it’s not that this fire is completely preventable but we could have probably had an impact on the behavior of the fire within the area that burned,” she reflects.

To see how, she points across the path, to a 17.5-acre plot where she lit a prescribed fire last May. Those trees remained green. Flames were only inches high. These lands will recover faster.

“They might have not burned so hot or so extreme in the oak woodlands if we had been managing them on a regular basis,” Berleman says.

She also thinks more planned burns could have saved Bouverie’s buildings. That hot and extreme fire torched all but one of them. Berleman went back to the preserve as the fire raged. She and two men were able to save that last building, David Bouverie’s own, using a bucket, a shovel and a chain.

“So now that building has a special place in my heart,” she laughs. “We spent a good 24 hours together.”

Berleman now works as a consultant, promoting the use of ecologically applied fire for private clients and the East Bay Regional Park District, among others. Paradoxically this summer, she’s deploying her “hot shot” training as a wildland firefighter, where the job is to stamp fires out.

“I felt like we’re sometimes putting out fires that were doing good work. Just because that’s what the machine does,” Berleman says. “That’s what we do, put out fires.”

Her hope is to reconcile the conflicting aims of these jobs, and the relationship between fire and California’s landscape, to get scientists and wildland managers heading in the same direction.

In Harm’s Way

Craig Thomas, conservation director for the Sierra Forest Legacy, says in the last 25 years, that’s become easier to do. But during those years, Thomas points out a different challenge has been growing: more people have moved into wildlands from cities.

“There is a, you know, thinking that a landscape is like a photograph,” he says ruefully. “You know, when you have these big beautiful trees and we want to freeze-frame them.”

Thomas argues that’s a bad idea. Fire is a natural disturbance, he says, “a process that is every bit as much of the picture of where you land as the trees are.”

For him, the forests are a movie, not a picture. Trees have a starring role, but so does fire. And it doesn’t have to be the bad guy in a summer blockbuster.

For a century, California has harnessed its water with concrete, building dams and reservoirs on an epic scale.

Now, as the state prepares to hand out $2.7 billion for new water storage projects, it looks as though that era of dam-building might be ending.

During the height of the California’s 5-year drought, state voters approved new funding for water storage as part of Proposition 1. This week, the California Water Commission will allocate those funds to the eight projects that have qualified after a lengthy analysis.

Some projects are classic dams, but several won’t get the windfall they’d been hoping for. Instead, next-generation projects are in the running, like using the state’s vast network of natural underground aquifers for water storage.

That’s sparked a fierce debate over how California can get more water.

Era of Dam-Building

After the Depression, California’s first major dam rose on a river of federal money. At the time, Shasta Dam on the Sacramento River was the second tallest in the country.

The dam-building era stretched into the 1970s, as California’s major water projects were built. Canals and aqueducts stretched across the state. One promotional film dubbed it “one of the greatest engineering and construction achievements of the modern age,” providing “water to protect the health of generations to come.”

“That’s all we’re trying to do today,” says Mario Santoyo, executive director of the San Joaquin Valley Water Infrastructure Authority. “We’re trying to build these things not for us in particular, but for our children.”

The group is championing a new dam project known as Temperance Flat. It would sit just upriver from the 300-foot-tall wall of concrete known as Friant Dam.

That dam, built in the 1940s, helped turn the San Joaquin Valley into an agricultural powerhouse. Almost all of the country’s almonds, pistachios and raisins come from just nearby.

“This is, for all practical purposes, one of the best prime agricultural areas in the world,” says Santoyo.

Santoyo says to keep crops growing, California needs the new dam, a project that supporters have had their eye on for decades.

“It’s a V-shaped canyon area which is almost perfect for placing a dam,” he says.

Faced with a price tag for that of about $3 billion, the San Joaquin Valley Water Infrastructure Authority applied for $1 billion in Prop 1 funding.

But after the California Water Commission analyzed the project under a new scoring system, it determined that Temperance Flat wasn’t eligible for the full amount. The funding request was dropped to $171 million.

“It was a major blow for us ’cause we didn’t see it coming,” says Santoyo.

And the reason? This water bond has a dramatically different approach to funding infrastructure.

Broader Benefits

“The bond was really clear: fund the projects that could provide the most public benefits,” says Rachel Zwillinger, who works on water policy for the environmental advocacy group, Defenders of Wildlife.

In the past, many water bonds supported the building of particular projects. But the way state lawmakers wrote Prop 1, funding can only go toward the public benefits that a project provides. That includes things like flood control, recreation, or improving habitat for endangered species.

[contextly_sidebar id=”5pFi75De6xCXlL1AmyzKkkija66FNFtt”]To Zwillinger, it’s a sign that California is learning from its past.

“We didn’t really think about and perhaps understand the impact that these dams would have on the environment,” she reflects. “We’ve seen native wildlife species crashing.”

California’s major dams blocked salmon from reaching their historic spawning grounds. Today, several iconic salmon runs are endangered.

Plus, the water in most rivers is already spoken for, so even if a new dam captures water, Zwillinger says most of it already belongs to someone else.

“We’re thinking about storage in new ways in California,” she says. “And hopefully moving past the era of on-river dams to other forms of storage that are going to serve us much better as we see more climate change and longer droughts.”

Underground Reservoirs

“The wastewater industry as a whole is learning that it’s not wastewater,” says Christoph Dobson, as he walks around Regional San’s wastewater treatment plant in Sacramento. It’s the end of the line for sewage from 1.4 million Sacramento residents — but not for long.

“Right now, we’re in the middle of the EchoWater project construction area,” he says, pointing to a battalion of cranes and trucks.

The plant is getting an almost-$2 billion upgrade. When it’s done, the treated wastewater coming out of the plant will be much cleaner than it used to be.

“It is not potable, so you can’t drink it, but you can do a lot with it,” he says. “So why not reuse this water?”

In a dry state like California, it’s not hard to find someone who wants it. Just a few miles away are acres of grapes, alfalfa, and almond fields. Currently, farmers there get water by pumping it out of the ground.

“The water under the ground is going down, there’s less of it,” Dobson says. “So, the idea is that we’ll take our high-quality recycled water and provide that to the farmers.”

In theory, farmers would then use the recycled water instead of over-drafting the groundwater. The $280 million in Prop 1 funding would go toward building a pipeline and distribution network to deliver the recycled water.

Raising the groundwater levels in the area could also be an ecological boon. If the water table is higher, it might improve the flow of the nearby Cosumnes River, which would benefit fish and wildlife.

Dobson admits that the project doesn’t seem to have a lot in common with a dam.

“But really it’s the same thing,” he says. “It’s just another reservoir. It’s just that reservoir is underground and you can’t see it. The scarcity of water has really made this project more possible.”

Three other projects expecting Prop 1 funding are based on groundwater storage or recycled water. The California Water Commission will make a final funding determination this week.

Rank #13: Something Else Adding Fuel to California’s Fire Season: Warmer Nights

Podcast cover
Read more

It will most likely be weeks before the County Fire west of Sacramento is completely extinguished. By Friday it had consumed nearly 140 square miles — an area larger than Las Vegas.

Firefighters say it was a vicious cycle of weather conditions, terrain and vegetation that made it one of the fastest-growing fires in recent memory. But there was something else at work: a relatively new challenge confronting fire crews.

Scientists have noted that nighttime temperatures — overnight lows, in particular — are rising at a faster rate than daytime highs.

‘We know this has been going on and impacting firefighting operations.’Tim Brown, Western Regional Climate Ctr.

“It is a significant difference,” says Tim Brown, who directs the Western Regional Climate Center in Reno. “Both temperatures are rising, but the minimum temperatures are rising even more.”

Brown says the difference in rates first started showing up in the data around 1980, and that overnight lows are now running about 2 degrees F above the 1981-2010 period that climate scientists use as a benchmark.

“We can see both the trends in the daily high temperatures,” he notes, “but an even stronger trend in the daily night time temperature.”

And it’s not good news for firefighters, who have complained in recent years that wildfires have not been “laying down” at night as they had in the past.

Brown says the trend has been particularly apparent at this time of year, and in the part of the state where the season’s first two major fires erupted.

“This rise has been occurring all over the state,” says Brown. “But where the current fires are — the County Fire, the Pawnee Fire — yes, over the last six years, we can see from these observations that the nighttime temperatures have been particularly warmer than usual during the spring months and into summer.”

It could’ve been a contributing factor when the County Fire started devouring landscape at the rate of 1,000 acres an hour, growing fourfold in size on its first night. The higher nighttime temperatures were just part of a witch’s brew of heat, low humidity, erratic winds, and terrain that made for a difficult fire fight.

“We know this has been going on and impacting firefighting operations,” says Brown.

California’s fire season is off to an early start. By early July, Cal Fire had responded to about 260 more fires than by the same time last year.

Brown says that since nights have warmed and humidity dropped, there isn’t as much moisture for “cured” or dead vegetation to absorb from the air. And, he says, if fire crews can’t make as much headway at night as they used to, it means there is also more smoke to contend with.

“There’s a substantial increase in the potential for public health impacts that we can link to this increase in nighttime temperature,” says Brown.

Rank #14: Shasta Dam Project Sets Up Another Trump-California Showdown

Podcast cover
Read more

Update May 14: A little more than three months after this story first appeared, the State of California and more than a half-dozen fishing and conservation groups sued to stop Westlands Water District from working to advance the Shasta Dam expansion project.

Original post:

The Trump administration is laying the groundwork to enlarge California’s biggest reservoir, the iconic Shasta Dam, north of Redding, by raising its height.

It’s a saga that has dragged on for decades, along with the controversy surrounding it. But the latest chapter is likely to set the stage for another showdown between California and the Trump administration.

‘We’re not talking. We’re explaining what we’re losing. And they’re not listening.’Winnemem Wintu Chief Caleen Sisk

Last fall, crews already had drilling rigs in place, taking core samples from the earthen banks around the 600-foot dam. That process was part of testing to see if its World War II-era foundation can support additional bulking up of the dam.

Taller Dam Means a Bigger Reservoir

This is what the federal Bureau of Reclamation calls “preliminary construction” work. For now, that’s all they have funding for, but the Trump administration is keen to press on with a $1.3 billion project to add more than 18 feet to the top of the dam, which is already taller than the Washington Monument. That would increase the size of the reservoir, Shasta Lake, by 14 percent.

“We’re extremely confident that there’s a lot of momentum behind this right now,” says Don Bader, area manager for the reclamation bureau, which operates the dam.

But that momentum is coming from Washington, not Sacramento.

“The new administration came in and they’re looking to add storage in California,” Bader explains, “and this was the one project that was ready to go, so that’s why it’s got most of the attention right now.”

Wild & Scenic

The project has also caught the attention of California officials, who say it violates the state’s Wild & Scenic Rivers Act, which protects one of the three major rivers that flow into Shasta Reservoir.

“The California Legislature protected the McCloud River from any construction that would expand the reservoir,” says Ron Stork, of  the advocacy group Friends of the River. “It’s been illegal to expand this reservoir since 1989.”

Environmentalists say that the $1.3 billion dollars could be better spent on more creative ways to conserve water, such as recycling, stormwater capture, and storing more water in underground aquifers. But President Trump is on the record promising Central Valley farmers more water.

“Any bean-counter would say this is crazy,” says Stork. “But this is a political dam.”

The additional 630, 000 acre-feet of capacity would be like taking Hetch Hetchy Reservoir — the Sierra lake that supplies San Francisco — and dumping it into Shasta … twice.

But nature is not likely to fill that order every year. Stork says the project would likely yield only about 50,000 acre-feet of water on average, annually. That’s a drop in the bucket relative to California’s water budget.

Sacred Grounds

In December, Stork joined about 200 others at an “open house” in Redding, designed to inform stakeholders about the project. One of them was Caleen Sisk, chief of the Winnemem Wintu tribe, whose sacred grounds run along the McCloud River.

At a public meeting in Redding, Winnemem Wintu Chief Caleen Sisk appeals to stakeholders to oppose the expansion of Lake Shasta. (Craig Miller/KQED)

She says the tribe already lost many of its sacred sites when the original reservoir was filled, back in the 1940s. The expansion would raise the lake level by about another 20 feet, pushing it farther up the McCloud River.

“For us, we have to be connected to those sacred places,” says Sisk. “And we’ve already lost 26 miles in the building of Shasta Dam — 26 miles have been given up.”

Sisk’s people still use numerous sites along the lower river for rituals, including rites of passage for young Wintu coming of age.

Sisk says nearly all of the tribe’s remaining sites would be put permanently underwater with the reservoir’s expansion. Reclamation says it’s “talking” with the Winnemem Wintu, but Sisk has a different take.

“We’re not talking,” she says, “we’re explaining what we’re losing. And they’re not listening.”

Powerful Player

Sisk was distressed to see the meeting in Redding being run by Westlands Water District, a politically powerful irrigation district  based more than 300 miles away, in Fresno, which could be the chief beneficiary of any additional water from the project.  It has also raised eyebrows that David Bernhardt, Trump’s acting head of the Interior Department, which includes Reclamation, is a former lobbyist for Westlands.

Westlands was hosting the Redding meeting because it’s preparing an environmental impact report for the project. Reclamation needs an investment “partner” to close the deal, and though there’s been no formal announcement, many assume that Westlands will put up hundreds of millions of dollars toward the project, in exchange for rights to the water it yields.

“That they would have the sheer boldness to do an EIR for an illegal project is still — it’s stunning to me,” says Stork.

State officials have reacted with similar dismay. This month, the state’s Water Resources Control Board sent Westlands a letter confirming that what they’re proposing is illegal under state law, and that as a state agency, Westlands “participation is prohibited.”

A consulting firm conducted the meeting on Westlands’ behalf, and while there was one Westlands official in attendance, consultants said he was “not authorized to talk to the media.” Several subsequent calls and emails to Westlands for this story went unanswered.

Still, the Bureau of Reclamation has made it clear that it intends to press on.

“We’re proceeding along the federal route here,” says Bader. “If California does not participate in this process, we’ll move along forward by getting the federal approval.”

Some might interpret that as saying they’re going through with this regardless of what California thinks.

“That’s one way to say it,” says Bader.

From Bader’s standpoint, there’s a lot at stake. Shasta’s the keystone in the giant Central Valley Project, which sends water to farms and cities in 29 California counties. But dams have consequences.

Insult to Injury

“Every time you put up a dam on the Sacramento River, it’s going to be bad for wildlife.”

John McManus heads the Golden Gate Salmon Association, an advocate for protecting the threatened fish … and the industries they support.

“And right now,” he says, “what they’re talking about is adding more insult to injury by raising that dam, impounding more water behind it, and further impairing salmon runs downstream.”

Federal dam operators say that a deeper reservoir would allow them to send more cold water downstream, to support salmon in the Sacramento River. (Craig Miller/KQED)

Reclamation says a deeper water pool behind the dam will allow them to put more cold water downstream to support the fish. In its project description, the bureau claims it will:

“…improve water supply reliability for agricultural, municipal and industrial, and environmental uses; reduce flood damage; and improve water temperatures and water quality in the Sacramento River below the dam for anadromous fish survival.”

But in 2014, the federal government’s own Fish & Wildlife Service recommended against the project, concluding that it would fail to protect endangered salmon in the Sacramento River and its tributaries. That report was later “rescinded” for further review, and has not resurfaced officially.

Reclamation officials hope to award a construction contract by the end of next year, and complete the project by 2024.

McManus thinks the courts will ultimately rule against the project — if it gets that far. With Democrats now in control of the House, congressional funding to elevate Shasta Dam might be another stream that gets cut off.

“My view is they will ultimately be stopped,” offers McManus, “but I could be wrong. It wouldn’t be the first time.”

Rank #15: Spring Forward, Fall Back, or Neither: Why Changing Our Clocks Might Fade Into History

Podcast cover
Read more

On November 6, Californians will weigh in on whether they want to continue changing their clocks twice a year. Proposition 7 on the statewide ballot would lay the groundwork for year-round Daylight Saving Time in the state.

Lots of people hate switching between Standard and Daylight time, especially in March when we “spring forward” and lose an hour of sleep. Studies show this chronological hiccup is linked to increased rates of heart attacks, strokes and traffic accidents. This is due to the disruption in our daily biological cycles, known as circadian rhythms.

Read the KQED Voters Guide on Proposition 7

And in case you’re wondering, the clock switch no longer means significant energy savings and has no real benefit for farmers.

Yet the measure does have its detractors. Some state politicians and editorial writers point to the last time the U.S. had year-round DST: in 1974 during the OPEC oil embargo – and people hated it.

“Public opinion polls showed that everybody liked Daylight Saving Time from March to October,” notes David Prerau, author of “Seize the Daylight: The Curious and Contentious Story of Daylight Saving Time, “but nobody liked it in the middle of winter.”

President Nixon had ordered the measure for two years. But it meant the winter mornings were dark and cold – especially in the northern latitudes. There were some reports of increased accidents in the morning, as kids traveled to school in the dark.

Getting on the Ballot

Pedestrian safety is always a high concern, says Assemblyman Kansen Chu, but Prop 7 is a totally separate issue.

Chu is a Democrat representing the South and East Bay and sponsor of the measure. Chu became interested in the issue after his dentist showed him medical studies linking a lost hour of sleep in the spring, to increased heart attacks, stroke and traffic accidents.

A study from the University of Colorado at Boulder found a 17 percent increase in traffic accidents on the Monday following the springtime switch.

To find out why this might be, I visited the Kriegsfeld Lab at UC Berkeley, where scientists study circadian rhythms. Post-doctoral researcher Benjamin Smarr tells me that every part of our body runs on a daily cycle.

“Pretty much anything you can name,” he says. “So because we have circadian clocks in every cell in our body, every organ in our body is made up of cells trying to keep time.”

When we throw our timing out of whack, from missing sleep, doing shift work or being jet lagged, it misaligns systems like our attention and perception, digestion, emotions, blood pressure and more.

“One thing falling apart looks scary,” notes Smarr, “when you realize that all these other things around it have also fallen apart and that they’re also sort of fighting with each other for saying, ‘It’s time to sleep,’ ‘No, it’s time to digest,’ ‘No, it’s time to be active’. It makes sense that jet lag feels bad, makes us [feel] sick.”

The practice of switching back and forth between Standard and Daylight Time has been under fire for a while, each spring the internet bubbles over with segments and articles such as:

– Last Week Tonight with John Oliver: Daylight Saving Time – How Is This Still A Thing?
Bustle.com: 7 Legitimately Scary Facts About Daylight Saving Time, Which Just So Happens To Fall On Halloween This Year
– The Boston Globe: Proof Daylight Saving Time Is Dumb, Dangerous, and Costly

How did we get here in the first place?

The History of Daylight Saving Time, Abridged

The idea dates back centuries, at least to 1784 when Benjamin Franklin was the American ambassador to France. He was in the habit of staying up late to write by candlelight and then sleeping until noon. In a satirical essay written for the “Journal de Paris” he describes waking one morning, due to a loud noise, at 6 a.m. and being shocked to see the sun was already up.

Your readers, who with me have never seen any sign of sunshine before noon, […], will be as much astonished as I was, when they hear of his rising so early; and especially when I assure them, that he gives light as soon as he rises. […] This event has given rise in my mind to several serious and important reflections. I considered that, if I had not been awakened so early in the morning, I should have slept six hours longer by the light of the sun, and in exchange have lived six hours the following night by candle-light; and, the latter being a much more expensive light than the former, my love of economy induced me to muster up what little arithmetic I was master of, and to make some calculations.

Benjamin Franklin is credited with being the first to propose (in jest) that humans shift their schedules to match sunlight hours. (Library of Congress Prints and Photographs Division)

Franklin even estimated Parisians could save 64 million pounds of candle wax a year by getting up with the sun. This is the essence of Daylight Saving Time in a nutshell: making the best use of the hours of sunlight.

The idea was kicked around again in the late 19th century, notably by a New Zealand entomologist who wanted more daylight in the evening for bug collecting, and British businessmen and politicians. But the first country to do anything about it was Germany during World War I, to save energy for the war effort. By shifting the clocks so that sunlight lasted later into the evening, people did not need to use electric lights as much.  Most countries involved in the war then followed suit. The U.S. adopted it in 1918.

After the war it was repealed and local areas could decide for themselves whether to keep it. Then came World War II.

“Within a month of Pearl Harbor, we put in Daylight Saving Time again,” says Prerau. “And when WWII ended it became voluntary and several parts of the country had it and several parts didn’t.

Unwinding History

California voters chose, by Proposition, to enact Daylight Saving Time in 1949 — that’s why it has to go before voters again if the current system is going to change. It wouldn’t change automatically, however. Proposition 7 would just be the first of a three-step process. If it passes, the state legislature and Congress also would need to give the OK.

One reason this time-switching scheme is falling out of favor: the energy savings are not what they used to be. Most recent studies show the effects of DST offer a one-half to 1.5 percent saving, or sometimes a loss.

“To my eye these are basically a wash,” says Dan Kammen, who runs an energy lab at UC Berkeley. “They’re not an argument for or against Daylight Savings Time.”

(And for the astute reader, yes it is “saving,” not “savings time.”)

Rank #16: Smoke-Chasers Help Predict Wildfire Behavior

Podcast cover
Read more

One thing that stands out in this already-staggering fire season is the repeated accounts of bizarre fire behavior that seem to defy conventional wisdom.

Now, scientists are looking for new clues to that behavior. It turns out that the smoke plume from a wildfire tells its own complex story that contains some of those clues, and in California, there’s a new breed of “smoke chaser” looking to decode them.

Scientists are probing smoke plumes from the Carr Fire and other wildfires to better predict fire behavior. (Josh Edelson/AFP/Getty Images)

When I arrive at the Carr Fire’s incident command post in Anderson, just south of Redding, Craig Clements had just come out of a briefing with the incident meteorologist. Every big fire has one.

“They’re having issues with the smoke and they want to know how deep it is,” explains Clements. “We’re gonna map the smoke layer.”

Clements runs the Fire Weather Research Lab at San Jose State State University — and he’s taken it on the road. The lab’s mobile unit is a white, heavy-duty pickup, outfitted with a cluster of weather instruments and a LIDAR unit. LIDAR is kind of like radar, but instead of using radio waves, shoots a beam of light skyward, in this case to make a vertical map of the smoke column.

SJSU’s mobile fire weather unit is the only one of its kind operated by a U.S. university. (Craig Miller/KQED)

“We can track the smoke,” says Clements, “but we can also measure the wind circulation patterns in the smoke plume.”

Meteorology student Jackson Yip pulls the rig off of Highway 299 onto an open field, about 5 miles from the fire line, and gets to work inflating a small weather balloon — about four feet across. It carries a transmitter the size of an eyeglass case, called a radiosonde, that will send data back to the truck. He lets it go and it shoots into the air.

“That’s a good sight. Come on, keep goin’, keep goin’!,” urges Clements.

It will keep going, sampling and transmitting data back once every second, until it reaches 40,000 feet or more above the earth. The fire lab crew will transmit their data to the meteorologist on duty at the command post, where it can help form a better picture of conditions aloft.

[contextly_sidebar id=”DtKkbwvPmAseBAsYXj8h5MqEwXQxwCdC”]Launch sites for weather balloons are “few and far between,” according to Clements, so the team’s ability to launch on site was a boon to the “i-met,” the incident meteorologist who asked them to do so.

“Wow–look at that,” Clements exclaims, as the information starts to form a picture. The first thing they notice is a strong inversion: a layer of air about 9,000 feet up that’s warmer than the air below.

“The air’s really, really warm above,” he observes.

That warm air acts as a lid on the lower atmosphere, which helps explain why the entire Sacramento Valley seems to be enshrouded in a yellow, smokey haze. But what the team is really looking for, are signs that the fire’s behavior might be changing.

A yellow pall of smoke haze hangs over Interstate 5 south of Redding, during the Carr Fire. (Craig Miller/KQED)

“If you have a very convective day, let’s say, in the atmosphere, where a lot of vertical motion is occurring,” Clements explains, “that can impact the fire behavior.”

One thing they can spot is something called a “velocity couplet,” where winds above the fire are moving in opposite directions, just meters apart. That indicates rotation, and the possible formation of fire “tornadoes,” like the one that added to the devastation near Redding.

They’re not seeing that on this day — but as the information comes in, it reveals something else that’s potentially dangerous.

“The air is really, really dry aloft,” notes Clements, “so if that really dry air mixes down to the surface, it could really impact fire behavior, because it’ll dry out the fuels.”

For now, it’s something to keep an eye on — no need to sound an alarm.

“As air descends, it’ll only warm more and get drier,” explains grad student Matthew Brewer. “If the sun’s able to warm the surface, and you start to get surface mixing, and we get convection, and get these big circulations going, and that could bring down some of the dry air; as air comes up, air has to come back down.”

Currently, San Jose State has the only mobile fire weather lab in the nation, and the immediate goal is research. But Clements hopes they can make the case for units like this to become a staple of wildfire management — especially when current fires seem to be breaking all the conventional rules of fire behavior.

“There are general rules of thumb,” Clements says, “but it doesn’t always happen. And so the more observations we can get on a wildfire in terms of meteorology, fire behavior, and fuels conditions, the better for predicting the fire.”

But maybe the bottom line of why they’re out here was best expressed by the undergrad student in the crew, 23-year-old Jackson Yip.

“Well, the papers that will be coming out of these observations and the knowledge we gain from it will ultimately save property and save lives,” he says.

This fall, the lab is adding a Ka-band mobile Doppler radar unit to its arsenal. Clements says that will give them unprecedented range and power to demystify the forces inside a fire’s smoke plume.

Rank #17: Outlook Grim But Not Hopeless as Climate Summit Convenes in San Francisco

Podcast cover
Read more

This week corporate and civic leaders from around the world will gather in San Francisco for the Global Climate Action Summit.

The effort was spearheaded by Gov. Jerry Brown to move the fight against global warming beyond the national commitments made in Paris nearly three years ago.

‘Thirty years ago we predicted it in the models — and now I’m feeling it. I’m experiencing it.’Inez Fung, UC Berkeley

“Look, it’s up to you and it’s up to me and tens of millions of other people to get it together to roll back the forces of carbonization,” says Brown in a promotional video for the summit.

It is likely to be Brown’s last big climate event before he leaves office next year, and it comes at a time when many scientists agree that time is running out for a major counteroffensive against global warming, which Brown has repeatedly called an “existential threat.”

“We are not prepared,” says Inez Fung, an atmospheric scientist at UC Berkeley, who can see the accelerated effects of a warming planet all around her, from raging wildfires in the western U.S. to death-dealing floods in India.

“Thirty years ago we predicted it in the models,” she says, “and now I’m feeling it. I’m experiencing it.”

‘None of the students in my classes have grown up in a normal climate. None of them.’Bill Collins, UC Berkeley

Across the U.S., the average temperature has risen almost 2 degrees Fahrenheit since the start of the 20th Century. In California, the heat has been turned up unevenly, with portions of the state warming over the same period by anywhere from one, to nearly three degrees. (The South Coast of California has experienced the biggest rise.)

And because the global oven was first fired up with the burning of fossil fuels more than 200 years ago, scientists say a certain amount of future warming is already “baked in.”

“We released enough carbon dioxide to continue warming the climate for several centuries to come,” observes Bill Collins, who directs climate and ecological science at Lawrence Berkeley National Lab.

“If we were to stop emissions entirely of all greenhouse gases right this minute,” he reckons, “we’d see roughly another half a degree centigrade … by the end of the 21st Century.”

That’s almost a full degree (Fahrenheit) already in the pipeline. So even if we shut down all emissions — which is not happening — we might still get to the 3.5 F threshold where scientists say the worst effects of climate change would kick in. (This is normally expressed by scientists as 2 degrees Celsius, which is the same as 3.5 F).

But Wait, There’s More!

“We’re seeing years now that basically blow the roof off of records that have been maintained by the National Climate Data Service back to the late 19th century,” notes Collins — and then a remarkable thought occurs to him:

“None of the students in my classes have grown up in a normal climate,” he adds. “None of them.”

Think about that. On the flipside, if you’re over, say 30 years old and can actually recall “normal,” well, that’s over.

“I have to say that all the projections that were made 30 years ago are still valid,” says Fung. “The only thing we had not anticipated … is that the CO2 increases much faster than we ever thought that it would.”

Despite the pledges made in Paris by nearly every nation in the world (the U.S. is alone among signatories in backing out of the climate accord, under the Trump administration), emissions are still rising. And even those historic commitments — if they’re all kept — won’t be sufficient to turn things around.

“No, we’re already beyond that,” says Fung. “The commitments, I think, are very good start, but they’re just not adequate.”

Don’t Give Up the Ship

All this grim talk might lead one to ask what point there is in trying to reverse the climate train. But recently refined climate models suggest that aggressively cutting emissions could improve future life on Earth in significant ways — or at least blunt the impact of continued warming. It could, for example, reduce periods of extreme heat in Sacramento from two weeks a year to as little as two days. The Sierra snowpack might shrink by “just” 20 percent, rather than 75 percent. That’s the optimistic scenario.

This week’s climate summit will pull together mayors, state and provincial governors, scientists and corporate leaders to keep momentum going with “subnational” actions to reduce greenhouse gas emissions. They’ll be joined by major players such as former Vice President Al Gore and former Secretary of State John Kerry, who signed the Paris accord on behalf of the U.S. with his tiny granddaughter perched on his lap.

One of the themes attendees will discuss is, “key building blocks required to peak global emissions by 2020,” a goal that seems wildly optimistic given current trajectories and with most of 2018 already behind us.

Transportation is the single largest source of climate emissions in California. After leveling off briefly, emissions from cars and trucks have been rising again. (Craig Miller)

“First thing we have to do as a global community is reverse course rather sharply,” says Collins. “We think it is technically feasible.”

Technically feasible, perhaps — but not easy. California, for instance, has the nation’s most aggressive efforts to cut greenhouse gases and overall, it’s working: total emissions are down 13 percent since 2004. And still, climate emissions from cars and trucks have been on the rise in recent years.

“Our cars are literally our time machines,” says Collins.

But unlike Doc Brown’s Delorean in the 1983 film, Back to the Future, Collins says most cars are driving us backwards.

“They’re taking the atmosphere to a chemical state that it has not been in for millions of years.” he says. “Currently, we have as much carbon dioxide in the earth’s atmosphere as we did five million years ago.”

The world 5 millions years ago was not “our” world. There were early ancestors of humans and the first tree sloths, but mammoths had yet to appear.

“Our steam engines, our factories, our cars, in the space of a little over 230 years since the start of industrialization, since the first steam engine,” notes Collins. “In 230 years they’ve taken us back five million years.”

And Collins says we have about 25 years — roughly one generation — to reverse course.

He and Fung both have their glimmers of optimism that technology and the boom in solar, wind and other forms of clean energy could quickly reduce climate emissions. Fung points to the young college students passing by us on campus as her best hope.

“I think I am optimistic about the young people. I’m optimistic that they are taking — they’re very proactive about the future.”

But Fung and Collins agree that time is what’s running out.

Rank #18: Breathing Fire: California’s Central Valley Bears the Brunt of Harmful Wildfire Smoke

Podcast cover
Read more

Worsening wildfires linked to the weather, climate change and forest management policies are causing unprecedented smoke pollution across the West and beyond, creating public health risks and undermining decades of air quality gains.

After 30 minutes of gardening, Donna Fisher’s eyes are burning. One is swollen shut. Since retiring to the forested foothills of the Sierra Nevada mountain range 20 years ago, the 74-year-old has cultivated a garden large enough to feed her and her husband well into the winter. For the past two years, smoke from wildfires has reduced the time she can spend tending to her vegetables before her asthma and bronchitis are triggered.

“It’s like somebody choking you, or putting a band around your chest and pulling it tight,” she said. Wildfire seasons in the Western U.S. are 105 days longer than they were five decades ago, billowing smoke that contains tiny chemical particles that threaten public health. “It used to be a few days, maybe a week at worse. Now it’s longer than it’s ever been.”

Smoke from wildfires is undermining decades of gains made in reducing air pollution from exhaust pipes and power plants. The number of days each year that wildfires foul the air is increasing in parts of the West, with worse expected as temperatures continue to rise.

‘You might not automatically have a heart attack or get asthma, but health effects can last for a year or more.’Loretta Mickley, Harvard chemist

Wildfires are projected to continue increasing in size and frequency, leading to more ‘smoke waves’ — days-long bouts of dangerous pollution. For asthmatics like Fisher, that means more days of lung-pinching pain and confinement indoors. For those who aren’t retired, it can mean missed work.

Someone exposed to smoke for a few weeks can feel health impacts long afterward, says Loretta Mickley, an atmospheric chemist at Harvard University who studies the relationship between smoke particles and health. In the longer term, exposure to the pollution is associated with earlier deaths.

“You might not automatically have a heart attack or get asthma,” Mickley said. “But health effects can last for a year or more.”

[contextly_sidebar id=”HWK9Tdsapvxh9XUBThIRFS0pCQet5a2x”]Fisher’s home is surrounded by forests that are naturally prone to burn, putting her at the front lines of smoke waves. Forty miles downhill, smoke from fires burning around California funnels into the Central Valley — a farming region where 6.5 million residents, many of them poor and working outdoors, endure some of the country’s most polluted air.

Since 2010, residents of the San Joaquin Valley, one of the two valleys that comprise the Central Valley, experienced at least 40 days each year when air quality was dangerous according to EPA standards.

“We have the biggest challenge that any air district has in the nation,” said Jon Klassen, a program manager at the San Joaquin Valley Air Pollution Control District.

Amid advances in reducing pollution from farms and the trucks that haul away their produce, longer and larger wildfires burning throughout California are ushering more smoke waves into this hard-hit region. Rising temperatures, a build-up of fuel on forest floors and the growth of neighborhoods in fire-prone areas are amplifying hazards. With these wildfires, comes more smoke.

Residents of the Central Valley endure greater risks than others in the U.S. of developing asthma, suffering heart attacks and strokes, and experiencing related mental health problems. Health care costs follow. The smoke affects day-to-day activities, putting classes and sports practices on hold and keeping the sick and elderly indoors.

Dan Jaffe, a chemistry professor at the University of Washington, Bothell who studies air quality, analyzed data from air monitors. He found that since 1970, air quality on the most polluted days each year improved on average across much of the continental U.S. But it worsened across swaths of the West, including the northern half of California and other areas affected by smoke waves.

“There really has been a statistically robust increase in wildfires in the Western U.S., and that’s directly impacting air pollution,” Jaffe said.

Breathing Fire

Regina Sorondo was born and raised in Fresno, a San Joaquin Valley city home to 500,000 people. Now, she’s raising her daughter and son here. Like one in four children living in Fresno County, both have been diagnosed with asthma.

“Last season to this season has been really bad,” said Sorondo, a call center employee, of the smoke from record-breaking fire seasons. “It’s really dangerous — it’s really scary.”

The tiny particles in the smoke, released when fire burns through fuel, is what Sorondo worries about most. Small enough to sneak through defense systems in the eyes, nose and mouth, the particulate matter, called PM2.5, can pierce through the lungs and travel through the bloodstream to organs including the heart.

“Particulate matter does affect how our central nervous system works,” said Wayne Cascio, a cardiologist and lab director at the federal EPA who studies the topic. “It also has an effect on inflammation, which we now know is an important role in driving cardiovascular outcomes.”

Staying indoors for prolonged periods, which is one of the few ways of guarding against particulate matter, can affect mental health. The Oregon Health Authority is working to help people in the southern half of the state, where wildfire smoke from California has led to sustained exposure, find psychologists and therapists.

The veil of pollution clouding much of the West this summer comes with fatal consequences. A study published in GeoHealth this summer concluded that early deaths related to wildfire smoke could double this century, even as deaths from breathing fossil fuel pollution decline amid a transition to cleaner energy.

“You see more patients coming in with typical symptoms of shortness of breath, wheezing, chronic cough,“ said Praveen Buddiga, an asthma doctor who has been treating patients in Fresno for 13 years.

These particles don’t just affect people living close to burning wildfires. In the weeks after the Carr Fire broke out nearly 350 miles north of Fresno, Buddiga said there was an uptick in patients visiting his clinic — particularly children. Smoke from Western wildfires in early August reached far as Louisiana and New York.

“What’s been dramatic is how the smoke is traveling eastward,” said the EPA’s Cascio. “It’s not just a local phenomena, it’s a national one.”

Reversing Decades of Air Quality Gains

Since the 1990s, when monitors began tracking PM2.5 and the EPA began fining states for breaching its standards, air quality nationwide has been improving. The number of people exposed to particulate matter has halved, and related deaths have fallen by about a third, according to a study by the National Institutes of Health.

With wildfires increasing in size and intensity, those gains are being undermined.

Climate Central researchers examined the number of days each year when PM2.5 levels exceeded federal standards. In both of the valleys that comprise California’s Central Valley, the number of these days decreased overall since 2000, but the proportion of those days occurring during the wildfire season increased.

‘Fire responds exponentially to warming. For every degree of warming there is in the Western U.S., the impact is a lot more.’Park Williams, Columbia Univ.

Health risks depend on age, health conditions and wealth. Poorer residents may not be able to miss work, and may live in drafty homes that allow smoke to permeate indoors.

Sheryl Magzamen, an epidemiologist at Colorado State University, has been tracking asthma-related hospital admissions in Western counties. At the beginning of August, as the Mendocino Complex Fire burned in northern California, she said she found that the likelihood of being hospitalized with asthma-related issues more than doubled along counties on the Oregon-California border.

“We breathe every minute of every day multiple times and it’s not something that we can stop doing,” said Magzamen. “That’s why this is concerning — this impacts everyone, it’s widespread and we’re seeing real impacts.”

The Role of Humans

Climate change, the whims of the weather and a century of firefighting practices have all been contributing to the destructiveness of the West’s recent wildfire seasons. Even as scientists and California firefighters point to the role of warming temperatures in fueling blazes, the Trump administration has been downplaying or falsely denying the links.

Rising temperatures in California caused in part by the heat-trapping effects of fossil fuel pollution are sucking moisture from Western landscapes and hastening the annual melting of snowpacks, drying fuel for wildfires.

“Fire responds exponentially to warming,” said Park Williams, a bioclimatologist at Columbia University. “For every degree of warming there is in the Western U.S., the impact is a lot more.”

Meanwhile, new residents continue to move into areas that are prone to burn, increasing risks to themselves, and accidentally or deliberately starting fires.

A century of aggressive firefighting to protect residents and property has also contributed to the devastation, leaving fuel on forest floors that would once have burned naturally during low-level fires kindled by lightning strikes.

Since a series of forest fires burned three million acres of Montana, Idaho and Washington in 1910, strategies for managing fires have generally favored extinguishing them as quickly as possible.

“We shouldn’t suppress all fires, they are part of our ecosystem and are necessary,” said Colleen Reid, a geographer at the University of Colorado-Boulder who is investigating how controlled burns and wildfires affect public health. “The challenge is having that perspective but also caring about the health of populations.”

In recent years, the federal government has been working with local and state agencies to boost prescribed burns, where officials set and manage low-level fires that consume shrubs, small trees and leaf litter. The efforts have been be limited by funding shortfalls. And nearby residents and local agencies sometimes oppose prescribed burns, worried about smoke pollution and risks that the fires will get out of control.

As the Trump administration eliminates climate protections and falsely denies climate change’s role in wildfires, it has proposed reduced spending to agencies researching and managing wildfires.

“When you’re spending $2.5 billion fighting forest fires, there’s not a lot left in the budget to do forest management,” Interior Secretary Ryan Zinke said in a radio interview Sunday with KCRA 3 in Sacramento. (During the interview, he incorrectly said this year’s wildfires have “nothing to do with climate change.”)

As federal government leaders reject basic science and move to shrink programs that could reduce risks, the air district that regulates air pollution in the San Joaquin Valley is becoming more flexible in allowing for prescribed burns — even when the air is already dirty.

“We’ve had to go further than any region has before,” said Klassen, of the San Joaquin Valley’s air district. It has implemented hundreds of rules in an effort to reduce pollution, including allowing more prescribed burns in the region.

Still, AJ Rassamni, who manages a car wash in Fresno, wants to see more comprehensive forest management. With fewer people leaving their homes amid recent smoke waves, fewer customers have been coming through his car wash. He provides masks to protect staff, but they can make breathing difficult.

Worried about effects from climate change, Rassamni bought an electric car and had solar panels installed at home to reduce his climate pollution. Without aggressive steps from governments to systematically reduce pollution and boost prescribed burns, though, his efforts alone will do little to protect Central Valley residents.

“Is it good for us?” he said. “No. But you have a life, and you’re going to live with the weather you have.”

Rank #19: Everything That Happened Monday During the Solar Eclipse

Podcast cover
Read more

Just after 10 a.m. Monday morning off the coast of Oregon the temperature dropped, shadows sharpened and the morning eerily turned to night. The sky filled with stars and planets. An unusual sunset glowed from the horizon in every direction.

The total solar eclipse awed onlookers as it swept across America. People within a narrow 70-mile wide band witnessed totality, while the entire country was treated to a partial eclipse.

Clear skies in Oregon set into motion a nationwide viewing event that had millions of Americans erupting into cheers or falling into stunned silence as the moon slipped in front of the sun. Social media sites erupted with photos, videos and audio.

Traffic crept along as people parked along highways and overflowed campgrounds and festivals. The Oregon Department of Transportation estimated 1 million visitors descended on the state.

If eclipse mania stoked any newfound fans they won’t have to wait too long for the next one. A total solar eclipse will travel from Texas to Maine on April 8, 2024.

3 p.m. If you were stuck inside or blocked by clouds today don’t fret. You can watch NOVA’s Eclipse Over America, tonight at 9 p.m.  on KQED 9 and streaming online.

NOVA investigates the storied history of solar eclipse science and joins both seasoned and citizen-scientists alike as they don their eclipse glasses and tune their telescopes for the eclipse over America.

https://www.youtube.com/watch?v=h1QPxE5BQbY

2:35 p.m. The first people to see this morning’s eclipse…
NASA astronaut Michael Barratt had his camera ready on board Alaska Airlines Flight 9671 this morning . The aircraft was destined out over the Pacific Ocean for the first glimpse of the total solar eclipse. Along with 100 other passengers, he pointed his camera out a round window as the moon slid in front of the sun. He had crafted a filter using a Chex cereal box.

KQED’s Lindsey Hoshaw was on the same flight with journalists, scientists, eclipse chasers and contest winners who cheered and even swore aloud when the sky darkened.

Totality, Hoshaw said, was magical from mid-air.

“It felt like something out of a movie,” she said.  “It was really inspiring to be around people who were so excited, who traveled all the way across the country to see something for two minutes.”

1:15 p.m. ‘The sky turned inside out’

Those who have chased eclipses around the world often speak of the transformative experience of totality. But KQED’s Danielle Venton says that researchers at the Lost River Field Station in Mackay, Idaho found today’s solar eclipse particularly special.

“Maybe because the sun was high in the sky and the air was pretty clear up there,” Venton said. “The corona was strongly visible.”

There were three “filaments” of solar wind visible to the scientists, who will be combing through the data they collected for months to come.

“Just with the naked eye we were able to see what looked like some coronal streamers, these long streaks of solar material coming away from the solar disk,” said Joseph Hutton, a researcher from Wales. “And maybe a few prominences, which showed up bright pink against the disk of the moon.”

Even hours after what she called an astounding experience, Venton was exhilarated.

“What was interesting was how the light changed,” she said. “It kind of felt more like moonlight. Shadows were especially vivid. There was this general feeling of euphoria, this wave of ‘Oh my god’s’ and gasps and cheering.” 

She says that when totality blanketed the Lost River Field Station, the sky turned dark where it was once blue, while the horizon glowed.

“It felt like the sky turned inside out,” she says.

12:42 p.m. KQED’s Lindsey Hoshaw captured the total solar eclipse from midair off the coast of Oregon on Alaska Airlines Flight 9671.

Morning weather update: Skies are forecast to remain clear in the path of totality in Oregon, while Idaho and Wyoming may have some patchy haze, according to the National Weather Service. Some cloud cover is gathering around the eclipse path in Nebraska, Kansas, Illinois and Iowa. In the Bay Area, low cloud cover may obscure the beginning of the partial eclipse, but skies are expected to clear mid- morning around peak viewing time.

[contextly_sidebar id=”WWfhZwP9WJYv0YjB0bt0GpJf1pPdjnkz”]

For the first time in 99 years, a total solar eclipse will sweep across the United States from coast to coast. More than 200 million Americans live within driving distance of the path of the total eclipse, called the path of totality.

From Oregon to South Carolina, cities and towns that lie within this narrow band are preparing for traffic jams and huge crowds, as millions gather to witness the phenomenon.

Those outside the path of totality will see a partial eclipse. The Bay Area will experience a 75 percent partial solar eclipse, peaking at 10:15 a.m.

HOW TO VIEW THE ECLIPSE SAFELY

  • DON’T look directly at the partially eclipsed or uneclipsed sun without eclipse glasses. (Sunglasses are not enough!)
  • DON’T look through camera, telescope or binocular lenses, even with eclipse glasses.
  • DON’T remove your eclipse glasses during the eclipse – that’s only safe during full totality, which California WON’T experience.
  • DO make a pinhole viewer if you don’t have eclipse glasses – or watch a high quality live stream online.

Here are the most important things you need to know this morning:

  • The entirety of the eclipse on American soil will last about two-and-a-half hours, with totality stretching from Oregon at 10:16 a.m. to Charleston, South Carolina at 11:47 a.m. PDT.  Totality lasts about two minutes at each location.
  • Solar eclipses occur when the moon passes between Earth and the sun, casting a shadow and blocking out the sun momentarily. Check out an animated view of an eclipse from outer space here.
  • Looking at the partially eclipsed or uneclipsed sun even for a moment can permanently damage your eyes. Watch a video on how to safely watch the eclipse here.
  • Solar eclipses aren’t rare in general — they happen every 18 months somewhere in the world. But if you stayed in one place, you’d wait 300 years on average to see one.
  • Keep an eye on the NASA live stream at the bottom of this page to watch the eclipse.

Rank #20: Oakland Zoo Makes Room for Big Predators. But Is it Enough?

Podcast cover
Read more

On a sunny, crisp day in April, LeRoy Little Bear and a dozen other tribal members from the Blackfeet Nation sang and danced a traditional rite to honor fourteen American bison they brought from Montana to the Oakland Zoo.

“Today is a very historic day because we’ve brought down buffalo that were almost extinct,” announced Little Bear from an overlook above the grazing herd.

These bison are rare, he said, because they haven’t been bred with cattle, unlike most bison seen today.

“You’re getting full-blood buffalo from the way they used to be,” Little Bear proclaimed with visible pride.

The bison are one of eight species at California Trail, the Zoo’s new exhibit hosting animals native — or once native to California. It’s  scheduled to open to the public in July 12.

Amy Gotliffe, the zoo’s conservation director, says the exhibit is a way to, “show people from the Bay Area what beautiful biodiverse wildlife we live with now, lived with before and could live with again.”

The bison, she says, are an example of how the zoo is trying to support animals in the wild. They will breed the bison and send the offspring back to the tribe to repopulate the wild herd.

[contextly_sidebar id=”aTk151tBzHueIylie0dSc9QmqJtX4Gam”]The zoo is also supporting a range of conservation efforts for each of their new animals, which include mountain lions, wolves, jaguars, California condors, bald eagles, black bears — even the long-extirpated grizzly bear.

For example, the four black bears at the zoo — a mother and her three cubs — were rescued from Pine Mountain Club in Kern County.

“There was a possibility of them all being put down because they were considered a nuisance,” said Gotliffe.

The zoo is partnering with the Bear League in Tahoe that helps to deter black bears from wandering into human areas.

The zoo also rescued four grizzly cubs from Alaska, and three mountain lion cubs, one from El Dorado County and two from Orange County. (The original California Grizzly is considered extinct, hunted out nearly a century ago.)

“The mountain lions are another story,” said Gotliffe, “They were all found abandoned [as cubs] on the side of the road.”

The zoo is working with the Mountain Lion Foundation and the Bay Area Puma Project and has created a task force called the Bay Area Cougar Action Team.

There’s also a plan to help California condors and bald eagles recover from lead bullet poisoning and then release them back into the wild.

In order to support all these partnerships, the zoo contributes 50 cents of its admission price ($22 for adults) as well as a portion of future Zoo membership fees, to conservation funds. Managers expect to raise at least a quarter of a million dollars this fiscal year for conservation.

The Association of Zoos and Aquariums, or AZA, recommends that zoos under its accreditation — like the Oakland Zoo — spend at least three percent of their revenue for conservation.

Gotliffe says they aren’t there yet, but they “have that goal in mind.”

She says with the opening of California Trail, which cost $80 million dollars and more than doubled the size of the zoo, they “will definitely be there.”

Fourteen bison graze on native grasslands in their new exhibit at Oakland Zoo, in what was once part of Knowland Park. (Sarah Craig)

Ironically, to achieve these conservation goals, the zoo expanded into 57 acres of Knowland Park, cutting into habitat for the threatened Alameda striped racer — also known as the Alameda whipsnake — and the California red-legged frog.

This angered park advocates who formed an organization called Friends of Knowland Park. In 2011, they waged a losing legal battle against the zoo and the City of Oakland, arguing that the city didn’t fully mitigate for impacts to the Alameda striped racer, native grasslands and sensitive plant species, like the Oakland star tulip and bristly leptosiphon.

[contextly_sidebar id=”Zzzpoj8QtT25UzxkQDqfkHX9iaAUm5po”]Under the existing requirements, the zoo must set aside 13 acres for native grasslands and 53 acres for the striped racer.

“We don’t know if the snake is going to go into an animal enclosure and I’m not sure if that’s a good thing or a bad thing,” said Shawn Smallwood, an independent biologist from UC Davis hired by Friends of Knowland Park to review the zoo’s plan.

But, he added, when you are dealing with an endangered species you must err on the side of caution.

“It’s just been so political,” says Karen Swain, the biologist hired by the zoo to monitor the frog and the snake during construction. She’s tasked with making sure construction workers don’t harm the snake.

“I’ve had to walk this honest line for what the biology is.”

In a way, the zoo is walking its own line: even making adequate space for its own animals remains controversial.

“We are trying to provide these guys with as varied of an environment as possible, to help them not be sitting around all day bored,” says Heather Paddock, one of the zookeepers in charge of the black bears.

The bears have more than an acre, dotted with dens, oak trees — even a swimming pool. The zoo says the bears exhibit, as well as all of their new exhibits, exceed the industry’s best standards.

But Mark Bekoff, an Emeritus Professor of Ecology who studies animal behavior at the University of Colorado, says zoos shouldn’t keep large predators because of their need to roam vast distances and hunt prey.

“Wide-ranging carnivores are among the animals who suffer the most when they are put into a cage,” he said, referencing a 2014 study published in Nature.

While Bekoff agrees that zoos should take in animals who have nowhere else to go, like these bears, he wants them to have more choice and control over their lives.

Zookeeper Paddock said she is trying to compensate for this with training and enrichment activities.

“We are providing them enrichment every single day, whether that’s a new food item or a new device, a toy, a new scent,” she said as she fed the black bears a mixture of bird seed, mealworms, romaine lettuce and oranges.

But Bekoff maintains that animals need privacy, too.

“Because let’s face it,” he says, “zoos bring animals in as money makers and so many animals in zoos suffer from boredom or stress from being unable to get out of the public’s eye.”

Heather Paddock, a zookeeper for the Oakland Zoo’s new exhibit, prepares a food enrichment activity for the zoo’s four black bears. She pours bird seed and mealworms into large round containers and tapes off the holes to make it harder for the bears to get the food. (Sarah Craig)

But Paddock says the public needs to connect with these animals so they care about saving them in the wild.

“You know the wild isn’t butterflies and rainbows for a lot of these animals,” she says. “They’re getting pushed further and further to the fringe of wild spaces.”

Ultimately, that fringe habitat could be the last refuge — for both snakes and bears — because there just isn’t enough wild space left.
