NASA scientist claims he’s been silenced

NASA’s top climate scientist said the Bush administration has tried to stop him from speaking out since he gave a lecture in December calling for prompt reductions in emissions of greenhouse gases, The New York Times said.

In an interview with the newspaper, James Hansen, director of NASA’s Goddard Institute for Space Studies, said that officials at the space agency’s headquarters had ordered the public affairs staff to review his lectures, papers, postings on the Goddard website and requests for interviews from journalists.
