John Kerry at COP26: We're going to come up with an agreement

US climate envoy John Kerry has told the BBC that he's confident of an agreement at COP26, as the summit enters the final day.

Negotiators from almost 200 governments are trying to strike a deal on how we tackle climate change.

He spoke to science editor David Shukman about arguments over finance, and whether the much talked-about line on phasing out coal and fossil fuels will survive.
