Contrary to what the global-warming alarmists claim, however, there is scientific dispute over ice measurements.
What is not lacking, however, is satellite imagery. You see, U.S. spy satellites are not the only imaging satellites, and while spy satellites may be better at picking up a license plate number from a moving car, plenty of satellites can measure ice caps. But don't take my word for it, just do a Google search (click image right).
So how about this headline: "Bush Hid Ice Images From People Who Can't Use Google."
Added: You don't need a spy satellite to see the hypocrisy on the roof of "go green" expert Thomas L. Friedman's mansion:
UPDATE 7-27-2009: Now Think Progress has joined the propoganda effort, Obama administration reveals evidence of global warming kept secret under Bush. Not only is the spin completely absurd and contradicted by publicly available information which shows widespread ice measurements (see comments below), as Macsmind points out, the released photos only compare ice levels in 2006 (a record level of ice) with 2007, even though up to 10 years of photos were taken.
