Guardian UK: Stern attacks politicians over climate 'devastation'

[tex-wyo-dem]

Politicians have failed to take on board the severe consequences of failing to cut world carbon emissions, according to Nicholas Stern, the economist commissioned by Gordon Brown to analyse the impact of climate change.

His stark warning about the potentially "devastating" consequences of global warming came as scientists issued a desperate plea last night for world leaders to curb greenhouse gas emissions or face an ecological and social disaster.

More than 2,500 climate experts from 80 countries at an emergency summit in Copenhagen said there is now "no excuse" for failing to act on global warming. A failure to agree strong carbon reduction targets at political negotiations this year could bring "abrupt or irreversible" shifts in climate that "will be very difficult for contemporary societies to cope with".

They said carbon emissions have risen more in recent years than anyone thought possible, and the world's natural carbon stores could be losing the ability to soak up human pollution.

The conference also heard that:

· A 4C rise could turn swaths of southern Europe to desert.

· Sea levels will rise twice as fast as official estimates predict.

· Modest warming could unleash a carbon "time bomb" from Arctic soils.

· A failure to cut emissions could render half of the world uninhabitable.

· Rising temperatures could kill off 85% of the Amazon rainforest.
