“Right after the year 2000, NASA and NOAA dramatically altered US climate history, making the past much colder and the present much warmer. …This alteration turned a long term cooling trend since 1930 into a warming trend,” asserted climate change skeptic Tony Heller (nom de blog Steven Goddard) on his Real Science website. This ignited a frenzy of commentary on the Internet and attracted the attention of the Drudge Report, the Telegraph, the Daily Caller, and Fox News. Reason Science Correspondent Ronald Bailey investigates the claims that NASA climate scientists are retrospectively fiddling with the national thermostat in order to change climate history as a way to bolster the case for man-made global warming.
