De Independent bericht: 'Almost too late' to stop a global catastrophe.
The possibility of avoiding a global catastrophe is "already almost out of reach", Sir Nicholas Stern's long-awaited report on climate change will warn today.
One terrifying prospect is that changes in weather patterns could drive down the output of the world's economies by an amount equivalent to up to £6 trillion a year by 2050, almost the entire output of the EU.
With world temperatures on course to rise by two to three degrees in 50 years, rainfall could be catastrophically reduced in some of the world's poorest countries, while others grapple with floods from melting glaciers. The result could be the largest migration of refugees in history.
These problems will be "difficult or impossible to reverse" unless the world acts quickly, Sir Nicholas will warn, in a 700-page report that is expected to transform world attitudes to climate change. It adds: "Our actions over the coming few decades could create risks of major disruption to economic and social activity, later in this century and in the next, on a scale similar to those associated with the great wars and the economic depression of the first half of the 20th century."
But the Chancellor, Gordon Brown, and Environment Secretary, David Miliband, will emphasise the positive message accompanying Sir Nicholas's stark warnings, because the report will also say that the world already has the means to avert catastrophe on this scale, although it will involve the huge expense of 1 per cent of global GDP (£0.3trn).
"The second half of his message is that the technology does exist, the financing, public and private, does exist, and the international mechanisms also exist to get to grips with this problem - so I don't think it's a catastrophe that he puts forward. It's a challenging message," Mr Miliband said.
Combating climate change could become one of the world's biggest growth industries, generating around £250bnof business globally by 2050. Sir Nicholas's report calls for a rapid increase in research and development of low carbon technologies, and in "carbon capture", which involves putting carbon emissions into underground storage rather than pumping them into the atmosphere.'
