No, we will not do anything.

To do something, we must cut greenhouse emissions a lot, and we must do it quickly. That's sure to mean economic disruption.

No elected administration - not in the U.S., not in the U.K., not in most places - will find it politically viable to take the actions which are required to mitigate climate change. I doubt that non-elected regimes could pull it off either. The third world has seen the American lifestyle, and they're grabbing for it with both hands - so even if Americans change their lifestyle completely, it won't matter. Our global destiny is set.

Our children will hate us, and our grandchildren - those few who survive - will hold us in contempt. And there is nothing you or I can do to change it.
