Everything that the administration has done has been counterproductive.

Winning slowly is another way of losing. Americans are screwing up our health care system again right now. That's going to cause grave trouble for people over the next five, 10 years. There are going to be lots of people who die, lots of people who are sick. It's going to be horrible. But 10 years from now it will not be harder to solve the problem because you ignored it for those 10 years. With climate change, that's not true. As each year passes, we move past certain physical tipping points that make it impossible to recover large parts of the world that we have known.

There is nothing that will discombobulate and degrade [more] the lives of people near the margin on this planet. You don't have to look much past New Orleans to see that. Who took the hit? Some of the poorest people in the U.S.

Scientists had said, "If you keep burning coal and gas and oil, you will melt the Arctic." And then the Arctic melted just as they had predicted. Did Shell Oil look at the melt and say, "Huh, maybe we should go into the solar-panel business instead?" No, Shell Oil looked at that and said, "Oh, well, now that it's melted it will be easier to drill for more oil up there." That's enough to make you doubt about the big brain being a good adaptation.

The world is on fire, and I'm doing my best to help steer the firetruck.

In reality, climate change is actually the biggest thing thats going on every single day.

I've got no advice. You guys know where you are and what will work. Just know that there are people all over the place working on this and that there's a great deal of solidarity around the world and we should try to build this big, sprawling movement that looks like the kind of energy system that we want - building lots of solar panels on lots of rooftops that are all interconnected.
