From ABC News: WASHINGTON, March 19, 2007 — – "A top government climate scientist told Congress today that political appointees without scientific backgrounds are corrupting the scientific process and confusing the public by censoring scientists and improperly editing their research on global warming.
“I believe that the nature of these edits is a good part of the reason for why there is a substantial gap between the understanding of global warming by the relevant scientific community and the knowledge of the public and policymakers,” said James Hansen, director of NASA’s Goddard Institute for Space Studies. “There has been so much doubt cast on our understanding that they think it’s still completely up in the air.” "
Republican critics strongly disagreed with Dr Hansen’s views. The hearing is the latest of several to explore government censorship of climate scientists at NASA and the National Oceanic and Atmospheric Administration (NOAA).
