UN draft stresses risk of global warming, from economy to health

By Alister Doyle OSLO (Reuters) - Global warming poses a mounting threat to health, economic growth, crops and water supplies, according to a draft report by top scientists that puts unprecedented emphasis on the risks of a changing climate. A leaked 29-page draft by the U.N. Intergovernmental Panel on Climate Change (IPCC), about the impacts of rising temperatures and due for release in March 2014, mentions "risk" 139 times against just 41 in its last assessment in 2007. The increased stress on risk may make the case for cutting greenhouse gas emissions clearer both to policymakers and the public by making it sound like an insurance policy for the planet, analysts say. Many governments, meeting in Warsaw from November 11-22 for U.N. talks on climate change, have long pleaded for greater scientific certainty before making billion-dollar investments in everything from flood barriers to renewable energies.
