Close upon the heels of the Union of Concerned Scientists' laughably biased survey, we have a Global Warming Smear from UK tabloids being reported straight up by the Washington Post after vigorous fact-checking. That is, they applied the standard pioneered by the New York Times' Jayson Blair and infamously associated with Dan Rather.
As a result, the American Enterprise Institute is accosted by:
... Senators Bernard Sanders, Patrick Leahy, Dianne Feinstein and John Kerry sent a letter to Mr. DeMuth complaining that "should these reports be accurate," then "it would highlight the extent to which moneyed interests distort honest scientific and public policy discussions. . . . Does your donors' self-interest trump an honest discussion over the well-being of the planet?"
It not just free speech these Copperheads want suppressed, it's the scientific method.
