At the June UK government conference on "Avoiding Dangerous Climate Change" at the Met Office in Exeter, scientists reported an emerging consensus that global warming must remain "below an average increase of two degrees centigrade if catastrophe is to be avoided," which means ensuring that carbon dioxide in the atmosphere stays below parts per million.
