US Secretary of State Hillary Rodham Clinton sought to put new life into flagging UN climate talks Thursday, announcing that the United States would join others in raising US$100 billion a year by 2020 to help poore nations cope with global warming.
She made the offer contingent on reaching a broader agreement at the 193-nation conference that covers "transparency," a reference to US insistence that China allow some international review of its actions controlling emissions of carbon dioxide and other greenhouse ases.
The announcement pointed up the US-Chinese diplomatic duel that has marked the two weeks of climate talks. They ground to a near-halt Wednesday as a chronic rich-poor divide flared into the open again, dimming the hopes of the Danish hosts for a comprehensive deal - a preliminary framework for a fomal treaty next year on combating climate change.
Environment ministers, having taken over from lower-level negotiators, got down to the final hours of talks Thursday in hopes of producing partial agreements to put before President Barack Obama, Chinese Premier Wen Jiabao and more than 110 other leaders a Friday's summit.
Such accords might include the issues raised by Clinton at a news conference here: long-term goals for financing climate aid, and monitoring of emissions controls.
The Clinton offer represented the first time the US government has publicly cited a figure in discussions here over log-term financing to help poorer countries build sea walls against rising oceans, cope with unusual drought and deal with other impacts of climate change, while also financing renewable-energy and similar projects.
