The Bush administration has routinely suppressed or distorted communication of climate change science to the public, a climate specialist at Nasa's Goddard Institute said on Tuesday.
The accusation, before the chief oversight committee in the House of Representatives, was reinforced by claims by Democratic lawmakers that the White House was withholding documents proving that Philip Cooney, a former Bush administration official who now works as a lobbyist for ExxonMobil, regularly edited climate reports for political reasons.
The testimony risks embarrassing the Bush administration ahead of the release on Friday of a landmark report on climate change science that will say there is a 90 per cent certainty that human activity is changing the world's climate and temperatures will rise by 3 degrees Celsius by 2100. It paints the most dramatic and comprehensive picture yet of a future of heatwaves, droughts and floods.
