I never like the question about letter grades, but I think Trump is failing. I think that every day there's another set of tweets and another set of controversies, and nothing seems to be getting done that's any good. And there seems to be kind of a policy paralysis in Washington. Even the appointments he's supposed to make as a new president, so I focus most of all on climate, and so my opinion of his time as president is certainly influenced by my opinion of the job he's done on climate. He's tried to move the country in the wrong direction.

Having worked on climate crisis for almost 40 years now, I've seen good days and bad days. And through all of that time, the general trajectory has been it's getting worse, it's getting worse. But in the last ten to 20 years, there's a second development; the solutions are more and more, and more available. So having this broad overview that I've developed over a long period of time, I now see the evidence that the solutions are available. We're gonna do this.

The ability of big money to shape perceptions - where you have four anti-climate lobbyists for every single member of the House and Senate - is a big factor.

Remember America, I gave you the Internet and I can take it away.
