"White House officials have undermined their own government scientists' research into climate change to play down the impact of global warming," Paul Harris reports in the Observer. "Emails and internal government documents obtained by The Observer show that officials have sought to edit or remove research warning that the problem is serious. They have enlisted the help of conservative lobby groups funded by the oil industry to attack US government scientists if they produce work seen as accepting too readily that pollution is an issue." Evidence includes an email from the Competitive Enterprise Institute [3] to the White House Council on Environmental Quality that "reveals how White House officials wanted the CEI's help to play down the impact of a report last summer by the government's Environmental Protection Agency (EPA), in which the US admitted for the first time that humans are contributing to global warming. ... The email discusses possible tactics for playing down the report and getting rid of EPA officials, including its then head, Christine Whitman. ...
The CEI is suing another government climate research body [4] that produced evidence for global warming. The revelation of the email's contents has prompted demands for an investigation to see if the White House and CEI are co-ordinating the legal attack."
