I think fracking for gas will reduce the incentive to turn to renewables, and I think it will do a lot of other damage across the countryside.

Everything that the administration has done has been counterproductive.

Everybody was cratered after Copenhagen. If the movie had worked the way that it should have, if it had been scripted by Holywood, the world would have come together and addressed the biggest problem it ever had faced and delegates would have embraced each other, and it all would have been a good happy scene instead of the complete farce and debacle that it turned into - maybe in certain ways, an absolute low point for human diplomacy.

In my own faith tradition, these questions have been very important. It has always been easiest for me to apprehend God in the natural world. I love to go to church, but when I really want to feel the presence of the divine I'm more likely to head up into the mountains.

My goal was to have as many of the primary sources as I could made available for people to look at and understand. Climate change is probably the most important thing that's ever happened, and yet people's understanding of it and its history remains a little fuzzy.

What makes us different? We're the creature that can decide not to do something that we are capable of doing.

We've lost half the summer sea ice in the Arctic. We've wiped out an enormous percentage of the world's coral reefs. We see huge changes in the planet's hydrology already, the cycles of drought and flood both amped up because warm air holds more water vapor than cold. These things are happening with a one-degree increase and going to two degrees won't be twice as bad, the increase in damage won't be linear, it most certainly will be exponential. So it was precisely the wrong moment to elect Trump.
