This article contains the original “hockey stick” graph that set me on the path to skepticism. Note that it is truncated at 1400AD even though the climate reconstructions went back 1000 and in some cases 2000 years. Starting at 1400AD was the depth of the Little Ice Age and excluded the earlier Medieval Warm Period. Truncated graphs are one of the most common frauds in science.
But Mann’s comeuppance is the result of his habit of suing anyone who critiques his work. He sued Tim Ball who criticized him for not releasing his methodology and supporting data for examination by other qualified scientists.
One of the basic standards in science is that if something cannot be reproduced, it didn’t happen. Mann apparently hoped Ball, who is 79, would die before the court ruled in the decade long suit. But finally the court has ruled in Ball’s favor, exposing Mann as a fraud, and requiring him to pay Ball’s legal costs as well. The ruling exposes Mann to criminal charges in the US.
Perhaps this will be the beginning of bringing real science back to the climate issue.
