UN to pitch strongest case over global warming

A UN panel of global climate scientists are to make their strongest case yet for man-made global warming in a new report due to be released today.

Drafts show that the Intergovernmental Panel on Climate Change (IPCC) is set to pronounce that most of the warming of the Earth's surface since the 1950s is "extremely likely" - at least 95% probable - to be man-made.

The 30-page summary that the IPCC produces, the first of four about global warming in the coming year, is intended to be the main point of reference on the science of climate change for governments trying to develop their response to global warming.
