Barack Obama promises that "the United States vigorously engage in negotiations" on climate

Barack Obama will not be attending the international conference on climate to be held in Poznan, Poland, on 1 December, but the elected president of the United States fully intends to radically change the U.S. data on global warming . Mr. Obama took the opportunity of an international summit devoted to this theme held on Tuesday 18 November in Beverley Hills, California, to assert, for the first time since his election, the reversal of the United States which, he said, will "vigorously engage" in international negotiations on climate. "When I take my duties, you can be sure that the United States to engage vigorously in these negotiations," he said. Sponsored by the California Governor, Arnold Schwarzenegger, Republican committed to environmental causes, the summit welcomed triumphantly statements by Barack Obama. The State of California has committed since 2006 in the fight against global warming through the adoption of a law on reducing emissions, in the spirit of the Kyoto Protocol, that George Bush has refused to ratify . Without a substitute for the Bush administration, which is still in business at the conference in Poznan, the Democrats will work very closely. "I have asked members of Congress who will attend the conference as observers me relate what they have learned," said Obama. Barack Obama has implicitly demarcated the words of the colistière of John McCain, Sarah Palin, who, during the presidential campaign, had questioned the human causes of global warming. "Wait no longer an option. Denial is no longer an acceptable response. The stakes are too high, the consequences too severe," he said. A new round of negotiations on climate started in 2007 in Bali to be completed in Copenhagen in 2009. The meetings in Poznan, bringing together nearly 10 000 participants from 170 countries, will test the willingness of countries to give or not a new impetus to an international policy to fight against global warming.
