synthesis report. Credit: F. BUSTAMANTE/AP The final summary of this year's three massive reports from the Intergovernmental Panel on Climate Change (IPCC) contains notably more urgent


language than before. Released on 17 November in Valencia, Spain, the synthesis report talks about ?dangerous anthropogenic interference with the climate system?. That phrase was absent from


previous IPCC publications because of objections from some political delegates to the panel's conferences. The report confirms that it is at least 90% certain that global warming is


real and caused by human activities, and sets out possible strategies for avoiding global temperature rises that could reach as high as 6 °C by the end of the century. Hans Verolme, head of


the WWF Global Climate Change programme in Washington DC, points to a section called 'reasons for concern', which he says acknowledges the risk of both abrupt climatic shifts and


irreversible impacts. Although there is ?a little hedging and qualifying going on?, he says, the fact that such a statement is in the report is notable. RIGHTS AND PERMISSIONS Reprints and
