US President Barack Obama acknowledged on Wednesday that the disappointment surrounding the outcome of the Copenhagen climate change summit was justified, echoing the widespread belief that the conference had not been successful. In an interview with PBS Newshour, he stated that while people had a right to be disappointed, the fact that some progress had been made was better than a complete collapse of the summit. The accord that Obama helped facilitate has been criticized by Sweden as a disaster for the environment, while British Prime Minister Gordon Brown described the summit as flawed or chaotic. Climate change advocates have also been highly critical of the minimal agreements reached at the talks, which fell short of original goals to reduce carbon emissions and address global warming due to ongoing disagreements between wealthy nations and developing economies. Some people criticized China specifically. British Environment Minister Ed Miliband accused China of interfering with efforts to make substantial cuts in global emissions. China rejected this accusation and accused London of trying to create rifts among developing countries regarding climate change. Obama did not accuse anyone directly, but he did mention that the Chinese delegation was not participating in negotiations until he intervened personally. Obama stated that when negotiations were on the verge of collapsing and the Indian prime minister was about to leave, the Chinese representatives were not participating in negotiations, but eventually the situation was resolved calmly. Obama reached an agreement with China, India, Brazil, and South Africa during the last hours of the conference after holding individual meetings with the leaders of these four nations. He stated that they were able to come to a consensus on non-binding targets for all countries, including China and India, who are expected to be the biggest emitters in the future.
