COP 30 delegates from around the globe are about to depart the Amazon city of Belem in Brazil. But not before some very important documents are drawn up. Camilla Born, former advisor to Cop 26 president Alok Sharma speaks to Tom Whipple about the scientific significance of the language negotiators choose to use.

And it’s the eve of The Ashes. As England Men’s Cricket Team line up against their Australian counterparts in Perth, cricket fans on both sides will be hoping for sporting records to fall.

Tom asks Kit Yates, author and Professor of Mathematical Biology and Public Engagement at the University of Bath.

Plus science broadcaster Caroline Steel is in the studio to discuss this week’s brand new scientific discoveries.
