SINGAPORE (AP): Former U.S. Vice President Al Gore said Wednesday that he may return to politics in the future but repeated his position that he has no plans to enter the 2008 presidential race.

``I may re-enter politics at some point in the future because I'm only 59 years old,'' Gore told reporters on the sidelines of a forum in Singapore.

Gore said he has ``no plan'' to run in the 2008 presidential election but aims to make the environment a focus of public discussion during the campaign.

``There is no single candidate that is putting forward a comprehensive argument about the environment or making climate change a priority,'' Gore said. ``I will continue to work so that public opinion will push all candidates to make climate a priority.''

Gore lost the 2000 U.S. presidential election to George W. Bush despite winning the popular vote.
