40 years ago a hole was discovered in the ozone layer. It provoked an international effort to ban the chemicals that were destroying our protection from the sun. Tom Heap and Helen Czerski are joined by Jonathan Shanklin, one of the team that realised that CFC chemicals used in aerosol cans and refrigerants were helping to create a 20 million square kilometre hole in the ozone layer above Antarctica.

They discuss the unparalleled international unity that swiftly banned the worst of the ozone-destroying chemicals and ask why we can't come up with a similar solution for manmade climate change. Tom will be delving into the black market in refrigerants and meeting the South American detectives dedicated to hunting down the chemicals that still threaten the ozone layer and come with an enormous cost to the climate.
