Global Warming Impacts Will Worsen in Coming Decades

Richard Kerr (Science April 13, News Focus) summarizes the latest report of the United Nations-sponsored Intergovernmental Panel on Climate Change (IPCC). The Report of Working Group II (WGII) was released last week, following the release in February of the Working Group I Report.

Excerpt from Kerr's analysis:
"The latest IPCC report sees a bleak future if we humans persist in our ways. The climate impacts, mostly negative, would fall hardest on the poor, developing countries, and flora and fauna--that is, on those least capable of adapting to change. Even the modest climate changes expected in the next few decades will begin to decrease crop productivity at low latitudes, where drying will be concentrated. At the same time, disease and death from heat waves, floods, and drought would increase. Toward midcentury, up to 30% of species would be at increasing risk of extinction."
