There are so many symptoms of this disease it's hard to know where to start to catalogue them, but just look at the effects on hydrology - on the way water moves around the planet.

We've built a new Earth. It's not as nice as the old one; it's the greatest mistake humans have ever made, one that we will pay for literally forever.

The idea that China and India will just abandon climate action is not true, because they're doing it for more reasons than we are.

I think the best way is to keep stressing, that, as we build out a new energy system, one of the best things about it, if we do it right, will be that it will be more local, more democratic, more distributed, and, in the long run, much more economically sensible.

We believe that we live in the 'age of information,' that there has been an information 'explosion,' an information 'revolution.' While in a certain narrow sense this is the case, in many important ways just the opposite is true. We also live at a moment of deep ignorance, when vital knowledge that humans have always possessed about who we are and where we live seems beyond our reach. An Unenlightenment. An age of missing information.

Climate change is a huge problem, an almost insoluble problem.
