Leaked UN Report Shows Cuts Offered at Copenhagen Would Lead to 3C rise
With the talks entering the final 24 hours on a knife-edge, the emergence of the document seriously undermines the statements by governments that they are aiming to limit emissions to a level ensuring no more than a 2C temperature rise over the next century, and indicates that the last day of negotiations will be extremely challenging.
The emissions cuts offered so far at the Copenhagen climate change summit would still lead to global temperatures rising by an average of 3C, according to a confidential UN analysis obtained by the Guardian.
With the talks entering the final 24 hours on a knife-edge, the emergence of the document seriously undermines the statements by governments that they are aiming to limit emissions to a level ensuring no more than a 2C temperature rise over the next century, and indicates that the last day of negotiations will be extremely challenging.
A rise of 3C would mean up to 170 million more people suffering severe coastal floods and 550 million more at risk of hunger, according to the Stern economic review of climate change for the UK government – as well as leaving up to 50% of species facing extinction. Even a rise of 2C would lead to a sharp decline in tropical crop yields, more flooding and droughts.
Tonight hopes of the summit producing a deal were rising after the US, the world's biggest historical polluter, moved to save the talks from collapse.
