GENEVA, Nov 25 (Reuters) - A "business as usual" approach to climate change could lead to a rise in global temperatures of 6 degrees or more, the head of the U.N. weather agency said on Wednesday.
However, decisions taken at a meeting of world leaders in Paris next week could still mean temperatures stay within 2 degrees Celsius of pre-industrial averages.
"Yes, it's still possible to keep to the 2-degree target but the more we wait for action the more difficult it will be," Michel Jarraud told a news conference.
