US aid offer boosts deal at UN climate talks

Large pieces of a climate deal fell into place Thursday with new offers from the U.S. and China, but other tough issues remained before President Barack Obama and other leaders can sign off on a political accord to contain the threat of an overheated world.

An announcement by Secretary of State Hillary Rodham Clinton that the United States would contribute to a climate change fund amounting to $100 billion a year by 2020 was quickly followed by an offer from China to open its books on carbon emissions to international review. AP
