How a Climate Doomsayer Became an Unexpected Optimist |

Bill McKibben isn’t known for his rosy outlook on climate change. Back in 1989, he wrote The End of Nature, which is considered the first mainstream book warning of global warming’s potential effects on the planet. Since then, he’s been an ever-present voice on environmental issues, routinely sounding the alarm about how human activity is changing the planet while also organizing protests against the fossil fuel industries that are contributing to climate change.
McKibben’s stark and straightforward foreboding about the future of the planet was once described as “dark realism.” But he has recently let a little light shine through thanks to the dramatic growth of renewable energy, particularly solar power. In his latest book, Here Comes the Sun: A Last Chance for the Climate and a Fresh Chance for Civilization, McKibben argues that the planet is experiencing the fastest energy transition in history from fossil fuels to solar and wind—and that transition could be the start of something big.

“We’re not talking salvation here,” McKibben says. “We’re not talking stopping global warming. But we are talking the first thing that’s happened in the 40 years that we’ve known about climate change that scales to at least begin taking a serious bite out of the trouble we’re in.”
On this week’s More To The Story, McKibben sits down with host Al Letson to examine the rise of solar power, how China is leapfrogging the United States in renewable energy use, and the real reason the Trump administration is trying to kill solar and wind projects around the country.

Al Letson: Bill, how are you this morning?
Bill McKibben: I’m actually pretty darn good, which one feels bad about saying in the midst of planetary ecological trauma and the collapse of our democracy, but it’s a beautiful day in the mountains of Vermont and in the midst of all that bad stuff, I’ve got one piece of big good news, which it’s actually kind of fun to share.
Yeah, I think in the midst of all the stress and pressure and sadness about the way the world is heading at this moment, I think having joy is a revolutionary act and it’s good. I think when you come outside and the sun is shining and it feels good outside, I don’t know. I don’t think we should be ashamed of it. I think we should bask it and hold onto it as long as possible because good Lord, who knows what’s next?
Amen. One of the results of having spent my whole life working on climate change is I never take good weather for granted. If there’s a snowstorm, I make the most out of every flake. If there’s a beautiful cool fall-like morning like there was today, nobody’s out in it quicker than me. So I take your point 100%.
How long have you been working in the field of environmental justice and thinking about the environment?
Al, when I was 27, I wrote a book called The End of Nature, so this would’ve been 1989 because I’m an old person. So, wrote a book called The End of Nature that was the first book about what we now call the climate crisis, what we then call the greenhouse effect. And that book, well, that book did well, it came out in 24 languages and things, but more to the point, it just made me realize that this was not only the most important question in the world, what was going to happen to the Earth’s climate, but the most interesting, that it required some understanding of science, but also more importantly of economics, of politics, of sociology, of psychology, of theology, of pretty much everything you could imagine. And so for 38 years now, I guess, it’s been my work and at some level, I wish I’d been able to spend my life on something not quite so bleak. On the other hand, I have to confess, I haven’t been bored in any point in there.
Yeah. How would you describe the environmental causes in America since you’ve been watching it for so long? It seems to me that there’s a lot of one step forward, three steps back, one step forward, three steps back.
I’d say it’s been more like one step forward, three quarters of a step back over and over again. And that’s a big problem because it’s not only that we have to move, it’s that we have to move fast. Climate change is really probably the first great question we’ve ever come up against that has time limit. As long as I’ve been alive and as long as you’ve been alive, our country’s been arguing over should we have national healthcare? I think we should. I think it’s a sin that we don’t, people are going to die and go bankrupt every year that we don’t join all the other countries of the world in offering it, but it’s not going to make it harder to do it when we eventually elect Bernie and set our minds to it than if we hadn’t delayed all this time.
Climate change isn’t like that. Once you melt the Arctic, nobody has a plan for how you freeze it back up again. So we’re under some very serious time pressure, which is why it’s incredibly sad to watch our country pretty much alone among the world in reverse right now on the most important questions.
Yeah. Is that forward movement and regression tied to our politics, i.e., is it tied to a specific party? If the Democrats are in office, we move forward, if Republicans come in office, we move backwards?
Yeah, in the largest terms. The fossil fuel industry, more or less purchased the Republican Party 30, 35 years ago. Their biggest contributors have been the Koch brothers who are also the biggest oil and gas barons in America. And so it’s just been become party doctrine to pretend that physics and chemistry don’t really exist and we don’t have to worry about them. Democrats have been better, and in the case of Joe Biden actually, considerably better. His Inflation Reduction Act was the one serious attempt that America’s ever made to deal with the........
