Friday is the last day of the Copenhagen climate talks, and the success of the conference could all come down to one tiny number: half a degree Celsius. While 102 countries have called for a limit on temperature rise of 1.5 degrees Celsius, the most powerful nations refuse to back down from a 2 degree target.
