Many Scientists Have Written on Mann

Richard Mueller on Mann’s “hockeystick”:

Now comes the real shocker. This improper normalization procedure tends to emphasize any data that do have the hockey stick shape, and to suppress all data that do not. To demonstrate this effect, McIntyre and McKitrick created some meaningless test data that had, on average, no trends. This method of generating random data is called Monte Carlo analysis, after the famous casino, and it is widely used in statistical analysis to test procedures. When McIntyre and McKitrick fed these random data into the Mann procedure, out popped a hockey stick shape!

PROFESSOR WILLIAM HAPPER, PHD:

On February 25th 2009, Professor Hopper 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.”


PROFESSOR WILLIAM HAPPER, PHD is considered to be the greatest living physicist, His bio included: Cyrus Fogg Brackett 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.

“The blade of the hockey stick could not be reproduced using either the same techniques as Mann and Jones or other common statistical techniques.”


Here is what PROFESSOR DAVID R LEGATES, PHD wrote about the hockey stick:


“Recently, my colleagues and I closely examined the “blade” of Mann’s latest temperature reconstruction (Geophysical Reseai'ch Letters, February 2004). According to the IPCC (2001) and many other published sources, the earth warmed only 0.6°C (1°F) during the 20th century. However, that contrasts sharply with the most recent reconstruction by Mann and Jones, which shows warming over the last century of 0.95°C (1.5°F) - a temperature rise more than 50 percent larger than tire IPCC claims. Mann’s warming estimate has grown substantially over the last couple of years, apparently to accommodate his continuing claim that the 1990s were the wannest decade of the last two millennia, but we found that tire blade of the hockey stick could not be reproduced using either the same techniques as Mann and Jones or other common statistical techniques. Since reproducibility is a hallmark of scientific inquiry and the blade does not represent the observed climate record, it is unreliable...”

“Today most scientists dismiss the hockey stick.”

Here is what DR MADHAV KHANDEKAR, PHD, Meteorologist and climatologist. Research Scientist with Environment Canada for 25 years. Editorial board member of The Journal of Natural Hazards, and former editor of Climate Research, had to say about the hockey stick:

The hockey stick was a graph constructed by some scientists about ten years ago. What it was meant to show was that the earth’s temperature from about 1080 till about 1850 remained essentially constant and then it started to shoot up. Lots of problems have been found out in the graph. The most glaring error in the hockey stick was that it did not show the Little Ice Age, which was significant. It did not show the Medieval Warm Period from the 8th to 12th century, which was also significant. There were errors in the use of the tree-ring data and also other errors. So today, most scientists dismiss the hockey stick. They do not consider the hockey stick graph to be a correct representation of the global mean temperature.


DR MADHAV KHANDEKAR, PHD is also a Member of the American Geophysical Union, the Canadian Meteorological and Oceanographic Society, and the American Meteorological Society. Former World Meteorological Organization lecturer in meteorology. MSc in Statistics from Pune University, PhD in Meteorology from Florida State University.

The hockey stick does not show the little ice age a time when the Themes froze over so solidly that they held ice fairs on it. The winters described by numerous writings of the time..

That proves the hockey stick is wrong.

---------------------------------

Here is what PROFESSOR RICHARD MULLER, PHD (a believer in global warming) had to say about Mann’s hockey stick:


  If you are concerned about global wanning (as I am) and think that human-created carbon dioxide may contribute (as I do), then you still should agree that we are much better off having broken the hockey stick. Misinformation can do real harm, because it distorts predictions. Suppose, for example, that future measurements in the years 2005-2015 show a clear and distinct global cooling trend. (It could happen.) If we mistakenly took the hockey stick seriously - that is, if we believed that natural fluctuations in climate are small - then we might conclude (mistakenly) that the cooling could not be just a random fluctuation on top of a long-term warming trend, since according to the hockey stick, such fluctuations are negligible. And that might lead in turn to the mistaken conclusion that global warming predictions are a lot of hooey. If, on the other hand, we reject the hockey stick, and recognize that natural fluctuations can be large, then we will not be misled by a few years of random cooling. (Massachusetts Institute of Technology’s Technology Review, October 15th 2004)
