DOHA, Qatar — Seeking to control global warming, nearly 200 countries agreed Saturday to extend the Kyoto Protocol, a treaty that limits the greenhouse gas output of some rich countries, but will only cover about 15 percent of global emissions.
The extension through 2030 was adopted by a U.N. climate conference after hard-fought sessions and despite objections from Russia. The package of decisions also included vague promises of financing to help poor countries cope with climate change, and an affirmation of a previous decision to adopt a new global climate pact by 2015.
Though expectations were low for the two-week conference in Doha, many developing countries rejected the deal as insufficient to put the world on track to fight the rising temperatures that are shifting weather patterns, melting glaciers and raising sea levels. Some Pacific island nations see this as a threat to their existence.
The conference was not "where we need to be in order to prevent islands from going under and other unimaginable impacts," said Nauru Foreign Minister Kieren Keke, who leads an alliance of small island states.
The two-decade-old U.N. climate talks have so far failed in their goal of reducing the carbon dioxide and other greenhouse gas emissions that a vast majority of scientists says are warming the planet.
The 1997 Kyoto Protocol, which controls the emissions of rich countries, is considered the main achievement of the negotiations, even though it didn't impose any binding commitments on China and other emerging economies. It was due to expire this year.
