If billionaires like Bill Gates and Jeff Bezos really want to maximize their efforts to solve the global climate crisis, they should focus less on gadgetry and more on getting governments to act.
That’s the message from Penn State climatologist Michael E. Mann, who delves into the changing circumstances of a decades-old debate in a book titled “The New Climate War: The Fight to Take Back Our Planet.”
At the age of 55, Mann is a grizzled veteran of climate wars: In 1999, he helped lay out the “hockey stick” projection for rising global temperatures, and in 2009 he was swept up in the Climategate controversy over hacked emails.

Mann has chronicled the conflicts over climate science in a series of books published over the course of the past decade. But in “The New Climate War,” he argues that the terms of engagement have shifted.
Amid waves of wildfires and extreme weather, it’s getting harder to deny that Earth’s climate is becoming more challenging. Instead, the focus of the debate is shifting to whether the climate challenge can be met — and if so, how best to meet it.
Gates has argued that investment in technology is the key to averting a catastrophe. “Tech is the only solution,” he said during last October’s GeekWire Summit. The Microsoft co-founder expands upon that perspective in an upcoming book titled “How to Avoid a Climate Disaster.”
Mann takes issue with that argument in “The New Climate War.”
“Where I disagree with Bill is that, no, I don’t think we need a ‘miracle,’ which is what he said [was needed] to solve this problem,” Mann told me during an interview for the Fiction Science podcast. “The miracle is there when we look up in the sky at the sun, when we feel the wind. … The solutions are there. It’s a matter of committing the resources to scaling them up.”
