I flew on Air Force Two for eight years, and now I have to take off my shoes to get on an aeroplane.

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.

I have a personal staff that helps me scour the internet and other media for the latest scientific peer-reviewed findings, the latest examples of climate-related extreme weather events, and the latest examples of progress. The world is in the midst of a sustainability revolution that has the scope of the industrial revolution, but with the speed of the digital revolution. That's not enough without new laws and the right kind of political leadership. But it does give us a base from which to build a movement that will save us from the most catastrophic consequences of the climate crisis.

Airplane travel is nature's way of making you look like your passport photo.

If the people that believed the moon landing was staged on a movie lot had access to unlimited money from large carbon polluters or some other special interest who wanted to confuse people into thinking that the moon landing didn't take place, I'm sure we'd have a robust debate about it right now.

I'm going to be focused on doing everything I possibly can to help solve the climate crisis.

I will tell you that what gives me a sense of joy is having work to do that justifies pouring every ounce of energy I have into it. That's really a blessing to have in your life. And it gives you energy back when you have the privilege of doing work that makes you feel that way.
