US climate envoy John Kerry defends Dubai climate deal

When the gavel came down at the global climate summit in Dubai last week, the deal struck by more than 200 hundred participants was heralded by its supporters as ground-breaking and historic. Critics of the agreement - aimed at limiting global warming to less than 1.5*C - say it's toothless and full of loopholes.

U.S. Special Presidential Envoy for Climate, John Kerry, has told Newshour that he's focusing on putting the deal into action. But some question whether the transition the deal talks about will happen quickly enough.
