Copenhagen. Accordarsi su un fallimento.

By the early hours of Saturday, representatives of the 193 countries who have negotiated here for nearly two weeks had not yet approved the deal and there were signs they might not. But Mr. Obama, who left before the conference considered the accord because of a major storm descending on Washington, noted that the agreement was merely a political statement and not a legally binding treaty and might not need ratification by the entire conference.
The three-page accord that Mr. Obama negotiated with the leaders of China, India, Brazil and South Africa and then presented to the conference did not meet even the modest expectations that leaders set for this meeting, notably by failing to set a 2010 goal for reaching a binding international treaty to seal the provisions of the accord.
Nor does the plan firmly commit the industrialized nations or the developing nations to firm targets for midterm or long-term greenhouse gas emissions reductions. The accord is nonetheless significant in that it codifies the commitments of individual nations to act on their own to tackle global warming.
“For the first time in history,” Mr. Obama said, “all major economies have come together to accept their responsibility to take action to confront the threat of climate change.”
