(AP) -- China accused developed countries Tuesday of backsliding on what it said were their obligations to fight climate change and warned that the U.N. climate talks in Copenhagen had entered a critical stage. In sharp comments made as the atmosphere at the U.N. climate conference in Copenhagen grows more divisive, Foreign Ministry spokeswoman Jiang Yu said there had been "some regression" on the part of developed countries on their position regarding financial support. China and the United States -- the world's top two carbon polluters -- have been at odds in Copenhagen.
Scientists have warned that the world's commitments so far fall short of what is needed to keep global temperature increases below 2 degrees C (3.6 degrees F) above pre-industrial levels and head off the worst of global warming. They say global warming will create rising sea levels, increasing drought, more extreme weather and the extinction of some species. Here's a look at images coming out of Copenhagen and a few from around the globe.
