Can the world fight climate change without the US? Donald Trump’s election victory threatens to derail the COP29 climate talks taking place in Azerbaijan this week. The US is one of the world’s biggest sources of carbon emissions but the president-elect has called global warming a hoax, championed the oil industry and promised to withdraw from international climate agreements.

On this episode, Lucy Hockings speaks to the BBC’s US climate correspondent Carl Nasman and the host of the BBC podcast The Climate Question, Graihagh Jackson.
