WASHINGTON Dec 4 (Reuters) - U.S. President Barack Obama is considering attending the climax of the Copenhagen climate change conference, one of his top advisers said on Friday.
Obama will go to the Dec. 7-18 talks on Dec. 9 but is not currently scheduled to return for the final days, when most of the hard bargaining on cutting greenhouse gas emissions is likely and dozens of other world leaders are due to attend.
"There are suggestions that he should be there on the 17th and 18th," Obama's national security adviser, James Jones, told reporters at the Foreign Press Center in Washington.
"Those discussions are under way and there's no decision at this time as to whether that schedule can be adjusted, so right now he's planning to be there on the ninth."
Some green groups have expressed disappointment that Obama would not attend the climax of the talks. Obama is due to head to the Norwegian capital Oslo after Copenhagen to collect his Nobel peace prize.
The United States will pledge in Copenhagen to cut its greenhouse gas emissions roughly 17 percent below 2005 levels by 2020. (Reporting by Ross Colvin, editing by Anthony Boadle) ((firstname.lastname@example.org; +1-202-898-8392; Reuters Messaging: email@example.com))
