You can see the hockey stick in the above graph. “Mike’s Nature Trick”, as his colleague, the now furloughed Phil Jones referred to Penn State “scientist’ Michael Mann’s creative reconstruction of historical temperature data, was to “hide the decline” in temperature data for the late 20th Century which would have obliterated the blade of the hockey stick.

The handle of the hockey stick was made straight by hiding the upward bulge of temperatures during the Medieval Warming period from 900-1300 A.D. The Little Ice Age which lasted from the 1500′s to the mid-19th Century was also manipulated to help straighten the handle of the hockey stick so that a consistent slightly downward trend of historical temperatures for 1,000 years followed by a sudden and marked upward trend in the last half of the 20th Century would result, lending credence to the theory that unprecedented global warming is occurring and human activity must be causing it.

It’s all a massive fraud on the order of Piltdown man.

Understanding Climategate’s Hidden Decline by Marc Sheppard at American Thinker is worth your time, I promise.

But before you head over there, take a look as this amusing “Hide the Decline” short music video.
