This week new research suggests that in recent years the Earth has been warming faster than we predicted. But scientists are undecided on whether this change is going to be permanent. Laura Wilcox, Professor of Aerosol-Climate Interactions at the University of Reading explains.

Tom Whipple is joined by Kit Yates, Author and Professor of Mathematical Biology and Public Engagement at the University of Bath. They mark the ten year anniversary of a game of ‘Go’ in which a computer programme called AlphaGo beat human Go champion Lee Sodol. Computer scientist at Google DeepMind Thore Graepel was witness to the game and talks about why the event has become a crucial moment in the story of AI.

Kit also brings Tom his pick of the science news.
