In the first programme in this series Amol Rajan and guests examine the pledges that have been made on climate change and how far we have gone towards meeting them. What has worked to reduce greenhouse gasses and what’s not working, including the role of COP. Is the commitment to limit global warming to 1.5 degrees the right one?

Graihagh Jackson, presenter of the BBC podcast ‘The Climate Question’ is with Amol, alongside guests Professor Saleemul Huq, Mikaela Loach, Emeritus Professor Bill McGuire and Sarah Bell
