But the truth is that we could win every other fight that we face and if we lose the climate fight, the other victories will be pyrrhic. I don't think even people who are worried about climate change quite understand the scale and speed with which we're now shifting the planet.

So far the earth has warmed about a degree Fahrenheit globally averaged. That doesn't seem like an enormous amount but it's unlike what we would have expected twenty years ago.

Probably nothing that we have ever managed to do quite equals the basic undermining of the physical stability of the planet on which most of the world's poor people depend.

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.
