Hugh Pickens writes writes "The NY Times reports that an inquiry by the Commerce Department's inspector general has found no evidence that NOAA scientists manipulated climate data (reg. may be required) to buttress evidence in support of global warming after climate change skeptics contended that e-mail messages between climate scientists that were stolen and circulated on the Internet in late 2009 showed that scientists were manipulating or withholding information to advance the theory that the earth is warming as a result of human activity. 'None of the investigations have found any evidence to question the ethics of our scientists or raise doubts about NOAA's understanding of climate change science,' says Mary Glackin, the agency's deputy undersecretary for operations. The inquiry, requested last May by Senator James M. Inhofe, Republican of Oklahoma, who has challenged the science underlying human-induced climate change, comes at a critical moment for NOAA, as some newly empowered Republican House members seek to rein in the EPA's plans to regulate greenhouse gas emissions, often contending that the science underpinning global warming is flawed. Inhofe says the report (PDF) was far from a clean bill of health for the agency, and that contrary to its executive summary, showed that the scientists 'engaged in data manipulation.'"
