We'd already lost the possibility of stopping global warming entirely. That hasn't been in the cards for a long time. The triumph of Trump probably means that we're not going to be able to stop it at the two-degree mark that the world had been aiming for. That's very bad news, mostly because the planet seems to be more sensitive than we thought to even small increases in temperature.

It's our own throat that we are cutting in the end along with everyone else's. We need to be exercising precisely the kind of leadership that might allow us to nudge China and India, say, onto different energy trajectories, in order to improve our own chances of surviving this century.

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.

Solar power seems to be truly bipartisan in its appeal.

The laws of Congress and the laws of physics have grown increasingly divergent, and the laws of physics are not likely to yield.

In the States we've had by far the largest demonstrations in the last few years. The largest civil disobedience actions about anything in US history in the last 30 years have all been centred around the climate.

If one wanted to stigmaitise, that's how one would do it - lots and lots of people saying "we're severing our ties".
