COPENHAGEN, Denmark — The UN climate conference has ended after two weeks of intense wrangling.

The conference accepted a new U.S.-brokered deal that offers billions to help poorer nations adjust to global warming but does little to cut emissions of greenhouse gases.

The 193-nation conference -- the largest, most important climate meeting in history -- was gaveled to a close at 3:26 p.m. (1426 GMT) Saturday, ending a 31-hour negotiating marathon.

Its last major action was considering the Copenhagen Accord, product of closed-door summit bargaining Friday between President Barack Obama and the leaders of China and other major developing nations.

Under the accord, richer nations pledge $10 billion a year in climate aid for three years, and set a goal of much more money eventually.

The accord also envisions deeper cuts in big polluters' greenhouse gas emissions, but does not impose limits.
