Slashdot | Climate Expert Says NASA Tried to Silence Him: "'The top climate scientist at NASA, James E. Hansen, says that the Bush Administration tried to silence him (NY Times) after he gave a lecture last month calling for prompt reductions in emissions of greenhouse gases linked to global warming. 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.' The administration's policy is to use voluntary measures to slow, but not reverse, the growth of emissions.'"
