THE HAGUE -- U.N. climate talks collapsed at the 11th hour Saturday after the European Union and the United States failed to settle a bitter row over ways to stop global warming.

Environmentalists called the dramatic result at the climate conference in The Hague a disaster for efforts to clean up the planet's atmosphere and protect poorer nations from devastating storms and floods.

As the two-week conference moved into its last desperate hours, some delegates had said the talks would collapse, but others held out the hope an agreement could be revived.
