Thinking small in Cancun

摘要

The gap between climate science and climate diplomacy grows ever wider. At the start of the latest round of climate talks in Cancun, Mexico, this week, the chairman of the Intergovernmental Panel on Climate Change, Rajendra Pachauri, warned that global emissions must peak by 2015 if the world is to avoid dangerous climate change. His message was reinforced by the UK's Royal Society, which the same day published a picture of global chaos in a world warmed by 4 ℃ - which it said could happen as early as the 2060s.
