Interview with author of Drawdown, Paul Hawken, the top 100 ways to reverse climate change, ranked by tonnes of carbon, $cost and $return. Which do we do?..all of them, enough variety to engage with everybody.

“If you had asked every person at COP21 in Paris (us included) to name the top 10 solutions in any order, I don’t believe anyone would have gotten it even close. That is still true. After 50 years of global warming being in the public sphere, we didn’t know the top solutions to reversing it. And there’s a reason: We never measured and modeled the top solutions. Instead, sincere, well-meaning people profess their beliefs. You have a prominent scientist asserting that if we don’t go all in with nuclear power, we’re toast. Vastly untrue. You have journalists assuring us that if we go 100 percent solar, we’ll stabilize emissions. That’s a scientific howler, too. People who are earnestly guiding us to climatic stability have not done the math. That’s all we do at Project Drawdown: math.”
