I would distinguish between Donald Trump and the United States of America. Although he is president, he does not speak for the country on the climate change, and that was vividly illustrated in the aftermath of his speech pulling the US out of the Paris Agreement. Almost immediately, not only did the rest of the world double down on its commitments, but also here in this country, governors, mayors, business leaders, they said, we're still in the Paris Agreement, and they're doubling down. A lot of cities have now made a decision to go 100% renewable energy.

I have a sense of mission on this climate crisis, and I'm trying to pour all the energy I have into it. And I hope that I, along with others, can catalyze the emergence of real solutions to the climate crisis. I think we're making a lot of progress. I think we're going to win this, but it matters how quickly we win it. So I'm focused on that.

Hey, you know what, I've gotta go on that 'Letterman' show. That show is so lame.
