"There are significant questions about the robustness of the numbers at the heart of the new report estimating more than 300,000 deaths are already being caused each year by global warming, with nearly twice that number possible by 2030. The report was commissioned by the Global Humanitarian Forum, created in 2007 by the former United Nations secretary general Kofi Annan, and reviews reams of data and earlier analysis by other researchers and groups."
