In 2007, the IPCC predicted that rising global temperatures would kill off many species. But in its new report, part of which will be presented next Monday, the UN climate change body backtracks. There is a shortage of evidence, a draft version claims. … Global warming is said to be threatening thousands of animal and […]…

Climate Forecast: Muting the Alarm
Even while it exaggerates the amount of warming, the IPCC is becoming more cautious about its effects.By MATT RIDLEY

March 27, 2014 7:24 p.m. ET    THE WALL STREET JOURNALThe United Nations’ Intergovernmental Panel on Climate Change will shortly publish the second part of its latest report, on the likely impact of climate change. Government representatives are meeting with scientists in Japan to sex up—sorry, rewrite—a summary of the scientists’ accounts of storms, droughts and diseases to come. But the actual report, known as AR5-WGII, is less frightening than its predecessor seven years ago.The 2007 report was riddled with errors about Himalayan glaciers, the Amazon rain forest, African agriculture, water shortages and other matters, all of which erred in the direction of alarm. This led to a critical appraisal of the report-writing process from a council of national science academies, some of whose recommendations were simply ignored.Others, however, hit home. According to leaks, this time the full report is much more cautious and vague about worsening cyclones, changes in rainfall, climate-change refugees, and the overall cost of global warming.It puts the overall cost at less than 2% of GDP for a 2.5 degrees Centigrade (or 4.5 degrees Fahrenheit) temperature increase during this century. This is vastly less than the much heralded prediction of Lord Stern, who said climate change would cost 5%-20% of world GDP in his influential 2006 report for the British government.The forthcoming report apparently admits that climate change has extinguished no species so far and expresses “very little confidence” that it will do so. There is new emphasis that climate change is not the only environmental problem that matters and on adapting to it rather than preventing it. Yet the report still assumes 70% more warming by the last decades of this century than the best science now suggests. This is because of an overreliance on models rather than on data in the first section of the IPCC report—on physical science—that was published in September 2013.In this space on Dec. 19, 2012, I forecast that the IPCC was going to have to lower its estimates of future warming because of new sensitivity results. (Sensitivity is the amount of warming due to a doubling of atmospheric carbon dioxide.) “Cooling Down Fears of Climate Change” (Dec. 19), …
