Independent: Nasa's climate scientists 'gagged by White House'

James Hansen, the Nasa scientist who first warned the US government about global warming, yesterday delivered a withering critique of the way the White House has "interfered" with climate scientists at the space agency.

Dr Hansen, the director of Nasa's Goddard Institute of Space Studies in New York, said that the space agency's budget for studying the Earth's climate has been slashed and that its scientists have been systematically gagged about speaking of their concerns.

In detailed written testimony delivered yesterday to the US House of Representatives, Dr Hansen said that there had been creeping politicisation of climate change with the effect that the American public has been left confused about the science of global warming.
