Slash emissions, fly by zepplin – 15 February 2012, The Economist

THE ECONOMIST has long accepted the scientific consensus that the world is warming and that this warming is being caused by carbon-dioxide emissions from human activity. Climate scientists generally believe that avoiding potentially catastrophic warming will require massive cuts in emissions. The world has generally failed to agree on such cuts, and The Economist now believes “a dash to stay under 2°C [of average temperature increase] is no longer plausible.”
