Look - every time is the wrong time and the perfect time to have a kid, and you just do it when you can.

Between [Speaker of the House] Paul Ryan, [Senate Majority Leader] Mitch McConnell, and Donald Trump's team, I don't see a lot of openings for making real progress.

We are altering the most basic forces of the planet's surface - the content of the sunlight, the temperature and aridity - and that brings out the most powerful questions about who is in charge. If you wanted to give a name to this theological problem, I think you could say that we are engaged in decreation.

We're not at the point of trying to stop global warming; it's too late for that. We're trying to keep it from becoming a complete and utter calamity

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.

Absent the net, we certainly couldn't have organized in 190 countries around the world. It's no substitution for face to face interaction - that's why we have "days of action" where people are in real contact with each other - but it's the cheap (and low-carbon) way to do an awful lot of the planning and organizing. And we can build, for $20k, a website as good as one Exxon can build for $20 million.

That's why people are standing up again to fight the Keystone pipeline in Nebraska and South Dakota and Montana. Everyone is well aware of what this industry is about. It engages not only in those kind of practices, polluting people's water, but it has polluted our political life now for a quarter century.
