DOHA, Qatar — Even as international climate talks ended this weekend with no new commitments on carbon emissions or climate aid from the United States, some were relieved the nation didn't make a weak deal even weaker.
Other countries are now watching to see if the Obama administration will back up post-election comments about climate change with renewed efforts to cut emissions at home, and pave the way for more ambitious targets as work proceeds to adopt a new global climate pact in 2015.
The two-week talks in Doha ended with an extension of the Kyoto Protocol, which was to expire this year, but which now will only cover 15 percent of global emissions since several developed countries, including Japan and Canada, have opted out. The U.S. never ratified the accord.
European Union Climate Commissioner Connie Hedegaard said Sunday that the U.S. negotiators were "careful not to block" the negotiations, adding that it's "still difficult to know whether they will actually invest political capital in committing to a new international deal."
Hedegaard said she hopes Obama "will present not only an enhanced domestic climate policy but also an enhanced U.S. engagement and willingness to commit more in an international climate context."
Both rich and poor countries have long accused the U.S. of hampering the global effort to fight climate change, which scientists say is raising sea levels, threatening low-lying areas and island nations, and shifting weather patterns with impacts on droughts, floods and the frequency of devastating storms.
Alone among industrialized nations, the U.S. rejected the 1997 Kyoto Protocol, the only binding treaty to reduce emissions of carbon dioxide and other heat-trapping gases.
