If it's wrong to wreck the planet, it's wrong to profit from the wreckage.

We're going to need that kind of movement, because the fossil fuel industry is a sprawling adversary - at work everywhere, its tentacles in everybody's politics, invulnerable, I think, to direct frontal assault, but probably more brittle than it guesses if we come at it from all sides.

Irene's got a middle name, and it's Global Warming.

A voluntary simplification of life-styles is not beyond our abilities, but it is probably outside our desires.

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.

To me, it's more important to take the 60-70% of people who really understand that there's a problem [of climate change] and get some percentage of them active than to try and stamp out the last embers of pre-scientific thought.

It is a complete embarrassment and literally shameful that the country that first of all invented environmentalism and gave it to the world, and second of all did all the science originally around climate and global warming and presented that to the world, has been the country that has refused to participate in a constructive way to the solution.
