Tony Heller, of RealClimateScience.com has kept track of temperature data manipulation for some period of time. He put together a short video that demonstrates how the catastrophic man-made global warming theory people make the past cooler and the present hotter. They do this to make you believe things are bad and that they will get worse if you don’t get religion and do what they say. After you look at Heller’s Video, you may get a new meaning for “man-made” global warming.
