By Barbara Lewis and Bate Felix PARIS (Reuters) - With encouragement from 150 world leaders ringing in their ears, government negotiators in Paris were on Tuesday left to turn the rhetoric into reality and agree a draft text of a global deal to slow climate change. U.S. President Barack Obama and Chinese President Xi Jinping made common cause on Monday with other countries to stress the urgency of an agreement to slow a rise in global temperatures blamed for spurring floods, heat waves and rising sea levels. The main sticking point is how to come up with the billions of dollars needed to finance the cleaner energy sources that are badly needed if emerging countries are to develop without relying heavily on fossil fuels.
US President Barack Obama said Tuesday global warming posed economic and security risks that had to be tackled immediately, but insisted the climate problem could be solved. If global warming continues, "then before long we are going to have to devote more and more of our economic and military resources not to growing opportunity for our people but to adapting to the various consequences of a changing planet," Obama said. "Climate change is a massive problem, it's a generational problem," Obama said, speaking on the sidelines of the November 30-December 11 UN conference north of Paris.
