The Intergovernmental Panel on Climate Change's (IPCC's) 31 March report on climate impacts and adaptation echoes many of the concerns raised by the last edition, issued in 2007. It says that climate change is already affecting human communities, agriculture, and natural ecosystems—and impacts are likely to grow in the future. But the report breaks with the past in drawing on an emerging body of social science to identify eight major risks posed by climate change, and to inform an extensive discussion of possible adaptation strategies. It also suggests that governments are, so far, spending too little to prepare. The report is the second of three major new reports from the IPCC. The first, on climate science, was released this past September; the third, on ways to reduce or mitigate greenhouse gas emissions, is scheduled to appear later this month.
