ClimateIPCC looks to vet, report climate-science better
Major U.S. science organizations aren’t the only ones to realize that the climate-science community has bungled – and badly – its portrayals of research on global change in recent months, if not years, and its responses to criticisms. Yesterday, the Intergovernmental Panel on Climate Change (a group established by the United Nations and World Meteorological Organization) said: “we recognize the criticism that has been leveled at us and the need to respond.” So will be convening an “independent review” panel to investigate what the organization’s procedures should be to vet not only the data it uses and how to synthesize conclusions based on those data, but also how it should convey those conclusions (and any necessary caveats) in reports to the public and policymakers.
