G8 leaders in crunch climate-change talks

G8 leaders will enter crunch talks today with emerging economies including China and India over plans to halt global warming.

The G8 reached an agreement last night – hailed as “historic” by British Prime Minister Gordon Brown – at the summit in L’Aquila, Italy, to seek to limit average global temperature increases to 2C by cutting their greenhouse gas emissions by 80% by 2050.
