NASA fights Bush Muzzle on Scientists

A week after NASA's top climate scientist complained that the space agency's public-affairs office was trying to silence his statements on global warming, the agency's administrator, Michael D. Griffin, issued a sharply worded statement yesterday calling for "scientific openness" throughout the agency.
It is not the job of public-affairs officers," Dr. Griffin wrote in an e-mail message to the agency's 19,000 employees, "to alter, filter or adjust engineering or scientific material produced by NASA's technical staff."

The statement came six days after The New York Times quoted the scientist, James E. Hansen, as saying he was threatened with "dire consequences" if he continued to call for prompt action to limit emissions of heat-trapping gases linked to global warming. He and intermediaries in the agency's 350-member public-affairs staff said the warnings came from White House appointees in NASA headquarters.
'In my three decades in government, I've never seen control of communications to the public so constrained," Hansen said over the phone this week. ''Communications from government scientists have never been so constrained."
