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.

How have predictions made by climate change experts been so wrong? This video is about why climate predictions have been divorced from reality, analysing the performance of past climate change predictions, in particular looking at James Hansen in 1988 and how his prediction ahead of the first IPCC report was so badly wrong.
