Science is warning us that if we do not quickly reduce the global warming pollution that is trapping so much of the heat our planet normally radiates back out of the atmosphere, we are in danger of creating a permanent 'carbon summer'.

The center of the earth is about a million degrees.

The task of saving the earth's environment must and will become the central organizing principle of the post-Cold War world.

Believe in the power of your own voice. The more noise you make, the more accountability you demand from your leaders, the more our world will change for the better.

I have a sense of mission on this climate crisis, and I'm trying to pour all the energy I have into it. And I hope that I, along with others, can catalyze the emergence of real solutions to the climate crisis. I think we're making a lot of progress. I think we're going to win this, but it matters how quickly we win it. So I'm focused on that.

Now we have things that are obviously false, leading us to war, leading us to deny people health care, leading us to ignore the climate crisis. We have to restore the integrity of the democratic conversation.

Our insatiable drive to rummage deep beneath the surface of the earth is a willful expansion of our dysfunctional civilization into Nature.
