BERLIN/PARIS, Nov 10 (Reuters) - German Chancellor Angela Merkel signalled on Tuesday she would visit Copenhagen to push for a U.N. climate deal with other leaders next month, saying failure would set back climate cooperation by years.

In Paris, the International Energy Agency (IEA) argued strongly for a U.N. carbon-capping deal, projecting that world use of fossil fuels would otherwise surge by 2030 and push up both energy prices and greenhouse gas emissions.

"A failure of the climate conference in Copenhagen would set progress on international climate policy back years. We cannot afford this," Merkel said of bogged-down 190-nation talks on a pact meant to be agreed in Copenhagen in December.

"Time is running out and the EU has developed a clear and distinct negotiating position. Now we expect commitments from the United States and countries like China and India," she said in a speech to the Bundestag lower house of parliament.
