The White House announced today that President Obama will attend the United Nations Climate Change Conference in Copenhagen December 9, the day before he accepts his Nobel Peace prize in Oslo, Norway.

“The president believes it is possible to reach a meaningful agreement in Copenhagen,” the White House statement said about the conference commonly referred to as COP-15. “The president’s decision to go is a sign of his continuing commitment and leadership to find a global solution to the global threat of climate change.”

During the two-week conference, international leaders are seeking to reach commitments nations will take to reduce emissions and other actions to slow climate change. The White House says President Obama is prepared to support a reduction of U.S. emissions by about 17 percent below 2005 levels in 2020. This target is in line with proposed legislation being considered by Congress.

Most heads of state will be attending the final days of COP-15. Do you think Obama’s presence at the conference will have an impact?
