… the situation is a little bit frightening! Kelly Wanser, Silver Lining Institute: climate modelling, interventions, and unlocking global south talent “quickly”
ClimateGenn hosted by Nick Breeze
In this ClimateGenn episode I speak to Silver Lining Institute Executive Director, Kelly Wanser about the urgent need to invest billions of dollars into expanding our global coverage of climate modelling capacity. [Support this channel on https://patreon.com/genncc] The worsening risks we face mean climate interventions to cool the planet are back in discussion in the corridors of power. We discuss the hold ups and the necessity for research that could give all of us a clear idea as to whether such schemes should be deployed or not. We also discuss how engaging the talents of global south scientists beyond the current superficial level could be a game changer in advancing our ability to respond, and to intervene, in order to counter the catastrophic impacts of warming we are seeing accelerating all around us. Quotes: “We are in the far end of what looks like a really bad place for climate change.” “The media is telling us the math doesn’t add up and the situation is getting a little bit frightening.” On climate interventions: “Looking at the system where it is and the dangers to people… and the dangers to natural systems, ecology and biodiversity, we are now seeing there is more openness in those communities who were extremely opposed to this than they were in the past… and that’s new!” “Ultimately, in the United States, and we’ll make this call to the rest of the world, we think there needs to be a step function, a real multi-billion dollar increase in investing against our observations and out model improvements. Separate from climate intervention, just to do the problems, we are not investing enough.” “We quickly need money and this technical access for researchers in the global south if we want to say that their participation is meaningful… I’ll speak bluntly, I think their participation is more superficial than it should be because they don’t have the capacity to actually do the science.” Excerpts from interview with Kelly Wanser, Exec Director of SilverLining Institute.
#95 – Kelly Wanser on whether to deliberately intervene in the climate
80,000 Hours Podcast with Rob Wiblin
How long do you think it’ll be before we’re able to bend the weather to our will? A massive rainmaking program in China, efforts to seed new oases in the Arabian peninsula, or chemically induce snow for skiers in Colorado. 100 years? 50 years? 20? Those who know how to write a teaser hook for a podcast episode will have correctly guessed that all these things are already happening today. And the techniques being used could be turned to managing climate change as well. Today’s guest, Kelly Wanser, founded SilverLining — a nonprofit organization that advocates research into climate interventions, such as seeding or brightening clouds, to ensure that we maintain a safe climate. Links to learn more, summary and full transcript. Kelly says that current climate projections, even if we do everything right from here on out, imply that two degrees of global warming are now unavoidable. And the same scientists who made those projections fear the flow-through effect that warming could have. Since our best case scenario may already be too dangerous, SilverLining focuses on ways that we could intervene quickly in the climate if things get especially grim — their research serving as a kind of insurance policy. After considering everything from mirrors in space, to shiny objects on the ocean, to materials on the Arctic, their scientists concluded that the most promising approach was leveraging one of the ways that the Earth already regulates its temperature — the reflection of sunlight off particles and clouds in the atmosphere. Cloud brightening is a climate control approach that uses the spraying of a fine mist of sea water into clouds to make them 'whiter' so they reflect even more sunlight back into space. These ‘streaks’ in clouds are already created by ships because the particulates from their diesel engines inadvertently make clouds a bit brighter. Kelly says that scientists estimate that we're already lowering the global temperature this way by 0.5–1.1ºC, without even intending to. While fossil fuel particulates are terrible for human health, they think we could replicate this effect by simply spraying sea water up into clouds. But so far there hasn't been funding to measure how much temperature change you get for a given amount of spray. And we won't want to dive into these methods head first because the atmosphere is a complex system we can't yet properly model, and there are many things to check first. For instance, chemicals that reflect light from the upper atmosphere might totally change wind patterns in the stratosphere. Or they might not — for all the discussion of global warming the climate is surprisingly understudied. The public tends to be skeptical of climate interventions, otherwise known as geoengineering, so in this episode we cover a range of possible objections, such as: • It being riskier than doing nothing • That it will inevitably be dangerously political • And the risk of the 'double catastrophe', where a pandemic stops our climate interventions and temperatures sky-rocket at the worst time. Kelly and Rob also talk about: • The many climate interventions that are already happening • The most promising ideas in the field • And whether people would be more accepting if we found ways to intervene that had nothing to do with making the world a better place.

Is Reflecting Sunlight from the Atmosphere a Bridge to the Future?: Kelly Wanser
Long Now: Conversations at The Interval
Recent data shows damage from climate change rapidly increasing. There are many scientifically proposed methods (from the U.S. National Academy of Sciences, the U.K. Royal Society, and the American Geophysical Union among others) for directly reducing atmospheric heat. Yet to date there are still no formal research programs or capabilities to further explore these geoengineering ideas. What are the potential risks and benefits? How do we balance this effort vs. emissions reduction and restoring the natural system? Kelly Wanser of SilverLining discusses her work advocating, educating and coordinating research on this important effort to combat climate change. Kelly Wanser, as Executive Director of SilverLining, helps drive research that will ensure safe pathways for climate for people and ecosystems within the coming decade. She works to accelerate adoption of technologies that help us understand and manage climate as a complex systems problem. Ms. Wanser works closely with leading scientists, engineers, technologists and government leaders on efforts to increase research and accelerate progress on reducing atmospheric heat. She testified before the U.S. House Space, Science and Technology Committee as part of a panel on "Geoengineering: Innovation, Research, and Technology." She serves as Board Director for BioCarbon Engineering, who use drone and AI technology to help restore ecosystems, and is a Senior Advisor to BlackBirch, whose hyper-local data helps companies manage weather risk.

Un traitement d'urgence pour notre fièvre climatique | Kelly Wanser
TEDTalks Science et médecine
Si nous réchauffons imprudemment la planète en libérant des gaz à effet de serre dans l'atmosphère, certaines émissions industrielles produisent également des particules qui réfléchissent la lumière du soleil et la renvoient dans l'espace. Cela freine le réchauffement climatique, que l'on commence à comprendre seulement maintenant. L'activiste pour le climat Kelly Wanser pose la question suivante : Pouvons-nous concevoir des méthodes permettant d'exploiter ce phénomène pour réduire davantage le réchauffement ? Découvrez les promesses et les risques de « l'éclaircissement des nuages » et comment il pourrait aider à soigner notre climat.
