World leaders overcame bitter divisions on Saturday over how to fight global warming and agreed to reach a new deal by 2009.

The contentious, two-week U.N. climate conference on the resort island of Bali ended with the United States, facing angry criticism from other delegations, relenting in its opposition to a request from developing nations for more technological help fighting climate change.

The new deal does not commit countries to specific actions against global warming. It simply sets an agenda and schedule for negotiators to find ways to reduce pollution and help poor countries adapt to environmental changes by speeding up the transfer of technology and financial assistance.

Despite an aggressive campaign led by the European Union to include specific emissions reduction targets for industrial nations — by 25 to 40% below 1990 levels by 2020 — the final road map has none.

The guidelines were eliminated after the United States, joined by Japan and others, argued that targets should come at the end of the two-year negotiations, not the beginning.
