The case for man-made global warming is even stronger than the Intergovernmental Panel on Climate Change maintained in its official assessments, according to the first scientific review published since December's Copenhagen conference and subsequent attacks on the IPCC's credibility.
An international research team led by the UK Met Office spent the past year analysing more than 100 recent scientific papers to update the last IPCC assessment, released in 2007.
Although the review itself preceded the sceptics' assault on climate science over the past three months, its launch yesterday in London's marks a resumption of the campaign by mainstream scientists to show that man-made releases of greenhouse gases are causing potentially dangerous global warming.
