"OSLO -- A global deal to combat climate change in 2015 looks more likely after promises for action by China, the United States and the European Union, but any agreement will probably be too weak to halt rising temperatures.

Delegates from almost 200 nations will meet in Lima, Peru, from Dec. 1-12 to work on the accord due in Paris in a year's time, also spurred by new scientific warnings about risks of floods, heatwaves, ocean acidification and rising seas.

After failure to agree a sweeping U.N. treaty at a summit in Copenhagen in 2009, the easier but less ambitious aim now is a deal made up of 'nationally determined' plans to help reverse a 45 percent rise in greenhouse gas emissions since 1990."
