Not as spectacular wrong as deniers.
PROFESSOR WILLIAM HAPPER, P Professor of Physics at Princeton University and a member of the US Government’s group of independent scientific advisors JASON, for whom he pioneered the development of adaptive optics. Recipient of the Davisson-Germer Prize in Atomic or Surface Physics, the Herbert P Broida Prize, and a Thomas Alva Edison patent award. Fellow of the American Physical Society and of the American Association for the Advancement of Science.
This is what Professor William Happer, PH.D. said " The whole hockey-stick episode reminds me motto of Orwell's Ministry of Information in novel 1984.
On February 25th 2009, Professor Happer testified before the US Senate’s Environment and Public Works Committee : The existence of climate variability in the past has long been an embarrassment to those who claim that all climate change is due to man and that man can control it. When I was a schoolboy, my textbooks on earth science showed a prominent “Medieval Warm Period” at the time the Vikings settled Greenland, followed by a vicious “Little Ice Age” that drove them out. So I was very surprised when I first saw the celebrated “hockey stick curve,” in the Third Assessment Report of the IPCC.
I could hardly believe my eyes. Both the Little Ice Age and the Medieval Warm Period were gone, and the newly revised temperature of the world since the year 1000 had suddenly become absolutely flat until the last hundred years when it shot up like the blade on a hockey stick… The hockey stick was trumpeted around the world as evidence that the end was near. The hockey stick has nothing to do with reality but was the result of incorrect handling of proxy temperature records and incorrect statistical analysis.
There really was a Little Ice Age and there really was a Medieval Warm Period that was as warm or warmer than today. I bring up the hockey stick as a particularly clear example that the IPCC Summaries for Policy Makers are not dispassionate statements of the facts…
The whole hockey-stick episode reminds me of the motto of Orwell’s Ministry of Information in the novel 1984 : “He who controls the present controls the past. He who controls the past controls the future.” In 2011, Will Happer expanded his thoughts on “controlling the past” : This damnatia memoriae of inconvenient facts was simply expunged from the 2001 IPCC report, much as Trotsky and Yezhov were removed from Stalin’s photographs by dark-room specialists in the later years of the dictator’s reign. There was no explanation of why both the Medieval Warm Period and the Little Ice Age, very clearly shown in the 1990 report, had simply disappeared eleven years later.
The IPCC and its worshipful supporters did their best to promote the hockey-stick temperature curve. But as John Adams remarked, “Facts are stubborn things, and whatever may be our wishes, our inclinations, or the dictates of our passion, they cannot alter the state of facts and evidence.” Maybe not. But the hockey stick certainly took “facts and evidence” on a wild ride. In order to control the future, the IPCC had to take control of the past and Mann’s graph was their way to do that.
