Doctors warn on climate failure

Failure to agree a new UN climate deal in December will bring a "global health catastrophe", say 18 of the world's professional medical organisations.

Expectations are running high for the UN climate change conference in Copenhagen this December. But will we get the global commitment for radical cuts in CO2 emissions that the world so urgently needs? The scientific evidence that global temperatures are rising and that man is responsible has been widely accepted since the 2007 report by the Intergovernmental Panel on Climate Change.1 There is now equally wide consensus that we need to reduce CO2 emissions to at most 50% of 1990 levels by 2050,2 if we are to have even a 50% chance of preventing temperatures exceeding pre-industrial levels by more than 2°C, considered by many to be the tipping point for catastrophic and irreversible climate change.
