Greenhouse gases reach record levels-UN agency

GENEVA Reuters – Concentrations of greenhouse gases, the major cause of global warming, are at their highest levels ever recorded and are still climbing, the U.N. World Meteorological Organisation (WMO) said on Monday.

The head of the agency, Michel Jarraud, said the trend could be pushing the world towards the most pessimistic assessments of the rise in temperatures expected in coming decades and said this underlined the need for urgent action.

The worst-case scenario envisaged by the IPCC (Intergovernmental Panel on Climate Change) in a 2007 report was that temperatures could rise by between 2.4 and 6.4 Celsius by the end of this century.
