james lovelock and polar cities

What you describe is quite depressing. Do you have any sense of hope?

Even the best climatologists will tell you in private that CO{-2} will continue to go up over the next 1,000 years even if emissions stopped today. You can't stop it once you get it going. Unless we can pull an amazing trick of cleverness, that's what's going to happen. And it's a normal thing in biology. Anything that overgrows its resources gets smacked back down again. I foresee a loss of as much as 80 or 90 per cent of the people on Earth by the end of the century. It's a distinct possibility, and I don't think there's much we can do to stop it. You just have to make sure those who remain will be able to survive it.
