Rank #1: 100 solutions to reverse global warming | Chad Frischmann

Nov 28 2018
Podcast cover
Read more

What if we took out more greenhouse gases than we put into the atmosphere? This hypothetical scenario, known as "drawdown," is our only hope of averting climate disaster, says strategist Chad Frischmann. In a forward-thinking talk, he shares solutions to climate change that exist today -- conventional tactics like the use of renewable energy and better land management as well as some lesser-known approaches, like changes to food production, better family planning and the education of girls. Learn more about how we can reverse global warming and create a world where regeneration, not destruction, is the rule.
