Dutch Agency Admits Mistakes In UN Climate Report

Hugh Pickens writes "The AP reports that the Netherlands Environmental Assessment Agency has taken the blame for one of the glaring errors that undermined the credibility of a seminal, 3,000-page UN report last year on climate change, and disclosed that it had discovered more small mistakes. However, the review by the agency also claims that none of the errors affected the fundamental conclusion by a UN panel of scientists: that global warming caused by humans already is happening and is threatening the lives and well-being of millions of people. The Dutch agency reported in 2005 that 55 percent of the Netherlands is below sea level, when only 26 percent is. The second previously reported error claimed the Himalayan glaciers would melt by 2035, which the Dutch agency partly traced to a report on the likely shrinking of glaciers by the year 2350. The original report also said global warming will put 75 million to 250 million Africans at risk of severe water shortages in the next 10 years, but a recalculation showed that range should be 90 million to 220 million. The analysis said future IPCC reports should have a more robust review process, and should look more closely at where information comes from."
