President Obama announced on Friday that negotiations among the the world's nations had resulted in a "meaningful and unprecedented breakthrough" on climate change.

One administration official, however, acknowledged in remarks to the Associated Press that it was only a first step and not sufficient in itself to head off global warming. Going by other reactions to the deal, that would appear to be an understatement.

The Guardian obtained a leaked draft of the agreement and reported that "it says countries 'ought' to limit global warming to 2C, but does not bind them to do so."

The Toronto Star explains, "It is not binding and it does not set new greenhouse-gas reduction targets. Instead, countries are to set their own emission reduction commitments, which would not be legally binding. Those commitments will be the subject of further negotiation, with the aim of a final deal at next year's summit in Mexico."

A Greenpeace representative told The Guardian, "This latest draft is so weak as to be meaningless. It's more like a G8 communique than the legally binding agreement we need. It doesn't even include a timeline to give it legal standing or an explicit temperature target. It's hard to imagine our leaders will try to present this document to the world and keep a straight face."

A representative of World Development Movement used even stronger language, saying, "This summit has been in complete disarray from start to finish, and now appears to be culminating in a shameful and monumental failure that will condemn millions of people around the world to untold suffering. The leaders of rich countries have refused to lead and instead sought to bribe and bully developing nations to sign up to the equivalent of a death warrant."

Adele Morris, Fellow, Global Economy and Development and Policy Director for Climate and Energy Economics, Global Economy and Development at The Brookings Institution and Kurt Davies, research director at Greenpeace USA, talk to Paul Jay about the Copenhagen "Climate Sham":

...it disappointed African and other vulnerable countries which had been holding out for deeper emission cuts to hold the global temperature rise to 1.5C this century. As widely expected, all references to 1.5C in past drafts were removed at the last minute, but more surprisingly, the earlier 2050 goal of reducing global CO2 emissions by 80% was also dropped.

Obama cast his trip as a sign of renewed US global leadership: "The time has come for us to get off the sidelines and shape the future that we seek; that is why I came to Copenhagen."

But the US president also said he would not be staying for the final vote "because of weather constraints in Washington".

Lumumba Di-Aping, chief negotiator for the G77 group of 130 developing countries, said the deal had "the lowest level of ambition you can imagine. It's nothing short of climate change scepticism in action. It locks countries into a cycle of poverty for ever. Obama has eliminated any difference between him and Bush."

John Sauven, executive director of Greenpeace UK, said: "The city of Copenhagen is a crime scene tonight, with the guilty men and women fleeing to the airport. Ed Miliband [UK climate change secretary] is among the very few that come out of this summit with any credit." It is now evident that beating global warming will require a radically different model of politics than the one on display here in Copenhagen."

Lydia Baker of Save the Children said world leaders had "effectively signed a death warrant for many of the world's poorest children. Up to 250,000 children from poor communities could die before the next major meeting in Mexico at the end of next year."
