"NASA's press office "marginalized or mischaracterized" studies on global warming between 2004 and 2006, the agency's own internal watchdog concluded.

In a report released Monday, NASA's inspector general office called it "inappropriate political interference" by political appointees in the press office. It said that the agency's top management wasn't part of the censorship, nor were career officials.

NASA downplayed the report as old news on a problem that has since been fixed. NASA spokesman Michael Cabbage said the space agency's new policies have now been hailed for openness by the U.S. Government Accountability Office."
