From some tiny portion of the wealth the west accumulated in a hundred years of filling the atmosphere with carbon.

Permafrost in the soil [is melting], in the boreal and arctic areas in the world, and, probably even more alarming in the last six or eight months, the data on what is happening to the ice shelves in Greenland and the west Antarctic has begun to cause people to radically reassess the earlier conviction that those ice shelves were stable on a kind of century-long time scale.

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

everyone knows, at some level, that the sharp line between "good weather" and "bad weather" is a fiction, that we need rain as surely as we need sun.

It was huge mistake to avoid working with the rest of the world because (a) we're the largest source of the problem: 4% of us who are in the U.S. produce 25% of the world's carbon dioxide.

People in low-lying countries like Bangladesh with almost 140 million people who are managing to feed themselves, whose carbon emissions can't really be calculated (they are a rounding error in the UN's attempts to do national comparisons), and yet, most of whose people are at risk from increased flooding due to rising sea levels.

No one is strong enough  -  given the magnitude of the task, everyone has to step up their game.
