Warm air holds more water vapor than cold, and so the atmosphere is about 4% wetter than it was 40 years ago. This loads the dice for flood and drought, and we're seeing both in stunning abundance.

Profiting from companies that are overloading the atmosphere with carbon and changing the atmosphere is wrong.

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.

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

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

I don't know how to make people who absolutely have to be obsessed with paying a week's energy bills... obsessed with climate change... It's very hard.

If one wanted to stigmaitise, that's how one would do it - lots and lots of people saying "we're severing our ties".
