A Tale of Two Climate Hockey Sticks

By S. Fred Singer

The false “hockey stick” graph with which (in 2001) the UN climate panel claimed that current surface temperatures are “unprecedented” in a millennium is at odds with hundreds of scientific papers and with their own previous position. There is nothing unusual about today’s temperatures; the world was warmer in the Middle Ages. However, the "hockey stick” graph showing a rapid increase in 20th century CO2 concentration is genuine.

The Third Assessment Report (2001) of the UN-sponsored IPCC (Intergovernmental Panel on Climate Change) espouses a temperature history over the last thousand years that resembles a "hockey stick" (HS). The ‘shank’ is the smooth decline of temperature from 1000 to 1900AD, followed by an apparent sharp rise in the 20th century (forming the ‘blade’ of a hockey stick). IPCC-AR3 promoted this rise as definitive evidence of human influence on climate; emission of carbon dioxide was supposed to cause the 20th century warming. But this temperature history is fake; it is contradicted by much other evidence....To Read More.....
