More than 190 nations agreed to work toward a treaty that would require all countries to reduce emissions that contribute to global warming.
"Two weeks of contentious United Nations talks over climate change concluded Sunday morning with an agreement by more than 190 nations to work toward a future treaty that would require all countries to reduce emissions that contribute to global warming.
The result, coming as the sun rose after nearly 72 hours of continuous wrangling, marked a tentative but important step toward the dismantling of a 20-year-old system that requires advanced industrialized nations to cut emissions while allowing developing countries — including the economic powerhouses China, India and Brazil — to escape binding commitments.
The deal on a future treaty was the most contested element of a package of agreements that emerged from the extended talks here. The delegates also agreed on the creation of a fund to help poor countries adapt to climate change, and to measures involving the preservation of tropical forests and the development of clean-energy technology."
