If the Holy Spirit is capable of the heavy lifting required to get Pat Robertson to change his mind, then that strikes me as a very good sign.

Winning slowly is another way of losing. Americans are screwing up our health care system again right now. That's going to cause grave trouble for people over the next five, 10 years. There are going to be lots of people who die, lots of people who are sick. It's going to be horrible. But 10 years from now it will not be harder to solve the problem because you ignored it for those 10 years. With climate change, that's not true. As each year passes, we move past certain physical tipping points that make it impossible to recover large parts of the world that we have known.

But tolerance by itself can be a cover for moral laziness.

I think we need to think of lots of ways to communicate. And we tried some at 350. We organised what they called the largest art project in the planet's history. We do a lot with art and music and things.

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

I think the world on the other side of fossil fuel is more local - the logic of sun and wind is diffuse and spread out, not concentrated like the logic of coal and oil.

Probably more than anything else, the place that we really see the effects of the power of even the relatively mild temperature increases so far is in the melting of everything frozen on the planet.
