> No serious climate scientist thinks we are going to fall off a cliff. There will be huge costs, yes. Civilization won't end, no. I've read more than a couple of articles, linked to here on HN, of climate scientists claiming that this is indeed a civilization-ending cliff. It's been mentioned like this in other media, for example in Cosmos 2. Yes, that's divulgation, but nonetheless, it means the scientists consulted for Cosmos 2 believe this. edit: just googled Michael Shellenberger. He is not a subject matter expert on climate change, and Wikipedia describes him as "a controversial figure" among environmentalists, which means his position is not mainstream and probably shouldn't be used to state "no serious scientist believes...". Note: I'm not saying he is wrong, he could be right; it's just that his view is not mainstream for now.
