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

A price on carbon sufficient to keep 80% of current reserves underground, rebated directly to citizens.

My house is covered in solar panels, I'm a great believer in all this - we all should be doing this.

We're mathematically past the point where the accumulation of individual actions can add up quickly enough to make a difference. The individual action that actually matters is not being an individual. It's joining together with other people in groups large enough to change the political dynamic around climate change.

I don't spend a huge amount of time fixated on climate denial because I don't think that their objections, though sometimes couched in science, are based in science. I think they're based in ideology. And I don't think there's anything you can do.

There's no huge mystery. If you dig up huge amounts of carbon, huge amounts of ancient biology, hundreds of millions of year's worth of ancient biology, and flush it into the atmosphere in a matter of decades, then it stands to reason that we're going to have enormous effects, and now we can see those effects all around us.

When you are in a hole, stop digging!
