In today's NY Times, another example of this administration silencing government officials who speak the truth based on science and facts:

The top climate scientist at NASA says the Bush administration has tried to stop him from speaking out since he gave a lecture last month calling for prompt reductions in emissions of greenhouse gases linked to global warming.... Dr. Hansen said he would ignore the restrictions. "They feel their job is to be this censor of information going out to the public," he said.... Dr. Hansen, 63, a physicist who joined the space agency in 1967, is a leading authority on the earth's climate system.... Dr. Hansen said that nothing in 30 years equaled the push made since early December to keep him from publicly discussing what he says are clear-cut dangers from further delay in curbing carbon dioxide.

The fresh efforts to quiet him, Dr. Hansen said, began in a series of calls after a lecture he gave on Dec. 6 at the annual meeting of the American Geophysical Union in San Francisco. In the talk, he said that significant emission cuts could be achieved with existing technologies, particularly in the case of motor vehicles, and that without leadership by the United States, climate change would eventually leave the earth "a different planet."

In one call, George Deutsch, a recently appointed public affairs officer at NASA headquarters, rejected a request from a producer at National Public Radio to interview Dr. Hansen, said Leslie McCarthy, a public affairs officer responsible for the Goddard Institute.

Citing handwritten notes taken during the conversation, Ms. McCarthy said Mr. Deutsch called N.P.R. "the most liberal" media outlet in the country. She said that in that call and others Mr. Deutsch said his job was "to make the president look good" and that as a White House appointee that might be Mr. Deutsch's priority.

The fight between Dr. Hansen and administration officials echoes other recent disputes. At climate laboratories of the National Oceanic and Atmospheric Administration, for example, many scientists who routinely took calls from reporters five years ago can now do so only if the interview is approved by administration officials in Washington, and then only if a public affairs officer is present or on the phone.
