We need to start prioritizing people, not polar bears.

Unfortunately, there's a lot of people in high places who understand the science but don't like where the policy leads them: too much government control.

You get a series of super-typhoons into Shanghai and millions of people die. Does the population there lose faith in Chinese government? Does China start to fissure? I'd prefer to deal with a rising, dominant China any day.

If you start getting instability in large powers with nuclear weapons, that's not a good day.

People working on climate change should prepare for catastrophic success.

Politicians have responsibility to act if the public opinion changes.

I like to think of climate action as a three-legged stool.
