US says 2 degree guarantee should be dropped by global climate change deal

The 2°C guarantee should be dropped from the global climate change deal to allow for more flexibility and avoid deadlock, US Special Envoy for Climate Change Todd Stern has said.

Speaking at Dartmouth College he said removing the 2°C specification from the agreement would allow countries to get on with actions to limit climate change now while leaving it open for further ambition at a later date.
