World Weekly climate change special: the Durban summit

In a World Weekly special on climate change, guest host Clive Cookson, science editor, is joined by Pilita Clark, environment correspondent, and Chris Giles, economics editor, to discuss how the conflict between the industrialised and emerging economies is shaping the discussions at the climate change summit in South Africa.

Also on the show, Richard McGregor, Washington bureau chief, and Leslie Hook, Beijing correspondent, examine how trade in renewable energy technologies is raising new disputes between the two key countries at the talks.
