**Chris Williamson** (0:00)
What's happening, people, welcome back to the show. My guest today is Richard Betts. He's the head of the Climate Impact Strategic Area at the MET Office, the lead author on several reports from the Intergovernmental Panel on Climate Change, and a professor at the University of Exeter. There are few areas of science as contested as the climate. I wanted to speak to someone who has been researching this area for more than three decades, to discover why there is so much disagreement over fundamental questions, like whether the earth's warming is actually caused by humans. Can we stop it? How accurate are the climate models? Should we switch to renewables? What does Richard think of Extinction Rebellion? How much are China to blame? And much more.

Richard Betts, welcome to the show.
I wanted to try and have a conversation with you to work out how there is so much disagreement about climate science. People are prepared to accept it. Eating too much makes you fat. Well, not everyone, but most people that are sane do. Smoking causes cancer, but climate science seems to probably be one of the most contested areas that I've seen. So for the people that aren't familiar with you and your background, what are your credentials and what do you do?
