Vulnerable Nations at Copenhagen Summit Reject 2C Target

More than half the world’s countries say they are determined not to sign up to any deal that allows temperatures to rise by more than 1.5C - as opposed to 2C, which the major economies would prefer.
But any agreement to reach that target would require massive and rapid cuts in greenhouse gas emissions combined with removal of CO2 in the atmosphere. An extra 0.5C drop in temperatures would require vastly deeper cuts in carbon dioxide and up to $10.5 trillion (£6.5tr) extra in energy-related investment by 2030, according to the International Energy Agency.
