We're clearly not going to stop global warming at this point. We've already raised the temperature of the planet one degree. We've got another degree in the pipeline from carbon we've already emitted. What we're talking about now is whether we're going to have a difficult, difficult century, or an impossible one.

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.

In reality, climate change is actually the biggest thing thats going on every single day.

The world is on fire, and I'm doing my best to help steer the firetruck.

The latest computer modeling I've seen indicates that at mid-century, there might be 150 million people classified as "environmental refugees."

Very few people on earth ever get to say: 'I am doing, right now, the most important thing I could possibly be doing.' If you'll join this fight that's what you'll get to say

I just keep trying to explain what's going on with our planet - and now, to explain what's going on with our politics, which explains why we're not doing anything about the former.
