Kumi Naidoo, executive director for Greenpeace International, pulls no punches explaining how the US team at the UN Climate talks in Durban is doing more harm than good.

The delegation charged with ensuring our nation's best interests continues to behave with a short-sightedness that is not merely inhibiting efforts, it actually risks reversing critical progress in policy addressing the climate change crisis.

He explains: "During the talks the U.S. is fond of insisting that they want to be involved, but at the same time makes derailing demands and announces commitments that barely survive the plane trip home."

He's calling for the US to remove itself from the talks outright, and it's worth reading his analysis of the event to understand why.
