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".
