Why have climate change predictions been so WRONG?

​In this video I wanted to address a common talking point – why have climate change predictions been so wrong? Year after year predictions are made that have no basis in reality, so why – especially in the aftermath of the latest IPCC report – should we trust climate scientists? In particular James Hansen and his prediction in 1988 didn’t turn out so well, did it?

Well, as it turns out, there’s a very good reason. Because they’re right most of the time, and their predictions, including those of the IPCC, have been borne out by reality. Sorry lol.
