I really hate to wade into this one again.
But once more, FOR THE RECORD...
There is NO statistical proof for global warming. The correlational studies between increases in carbon dioxide and mean global temperature DO NOT generate statistical poof that a relationship exists between the two, even if a statistical correlation is proven. So far, a statistical correlation has not been proven with correlations.
For such a correlation to exist there has to be only a 1 in 20 chance that the correlation DOES NOT exist. That is, to say, that there can be only a 5% chance that global warming does not exist.

Statistics needed, The Deniers -- Part I (Proof 'global warming' based on sloppy research)
National Post ^ | 2/2/07 | Lawrence Solomon

In the global warming debate, there are essentially two broad camps. One believes that the science is settled, that global warming is serious and man-made, and that urgent action must be taken to mitigate or prevent a future calamity. The other believes that the science is far from settled, that precious little is known about global warming or its likely effects, and that prudence dictates more research and caution before intervening massively in the economy.
The "science is settled" camp, much the larger of the two, includes many eminent scientists with impressive credentials. But just who are the global warming skeptics who question the studies from the great majority of climate scientists and what are their motives?
Many in the "science is settled" camp claim that the skeptics are untrustworthy -- that they are either cranks or otherwise at the periphery of their profession, or that they are in the pockets of Exxon or other corporate interests. The skeptics are increasingly being called Deniers, a term used by analogy to the Holocaust, to convey the catastrophe that could befall mankind if action is not taken. Increasingly, too, the press is taking up the Denier theme, convincing the public that the global-warming debate is over.
In this, the first of a series, I examine The Deniers, starting with Edward Wegman. Dr. Wegman is a professor at the Center for Computational Statistics at George Mason University, chair of the National Academy of Sciences' Committee on Applied and Theoretical Statistics, and board member of the American Statistical Association. Few statisticians in the world have CVs to rival his (excerpts appear nearby).
Wegman became involved in the global-warming debate after the energy and commerce committee of the U.S. House of Representatives asked him to assess one of the hottest debates in the global-warming controversy: the statistical validity of work by Michael Mann. You may not have heard of Mann or read Mann's study but you have often heard its famous conclusion: that the temperature increases that we have been experiencing are "likely to have been the largest of any century during the past 1,000 years" and that the "1990s was the warmest decade and 1998 the warmest year" of the millennium. You may have also heard of Mann's hockey-stick shaped graph, which showed relatively stable temperatures over most of the last millennium (the hockey stick's long handle), followed by a sharp increase (the hockey stick's blade) this century.
Mann's findings were arguably the single most influential study in swaying the public debate, and in 2001 they became the official view of the International Panel for Climate Change, the UN body that is organizing the worldwide effort to combat global warming. But Mann's work also had its critics, particularly two Canadians, Steve McIntyre and Ross McKitrick, who published peer-reviewed critiques of their own.
Wegman accepted the energy and commerce committee's assignment, and agreed to assess the Mann controversy pro bono. He conducted his third-party review by assembling an expert panel of statisticians, who also agreed to work pro bono. Wegman also consulted outside statisticians, including the Board of the American Statistical Association. At its conclusion, the Wegman review entirely vindicated the Canadian critics and repudiated Mann's work.
"Our committee believes that the assessments that the decade of the 1990s was the hottest decade in a millennium and that 1998 was the hottest year in a millennium cannot be supported," Wegman stated, adding that "The paucity of data in the more remote past makes the hottest-in-a-millennium claims essentially unverifiable." When Wegman corrected Mann's statistical mistakes, the hockey stick disappeared.
Wegman found that Mann made a basic error that "may be easily overlooked by someone not trained in statistical methodology. We note that there is no evidence that Dr. Mann or any of the other authors in paleoclimate studies have had significant interactions with mainstream statisticians." Instead, this small group of climate scientists were working on their own, largely in isolation, and without the academic scrutiny needed to ferret out false assumptions.
Worse, the problem also applied more generally, to the broader climate-change and meteorological community, which also relied on statistical techniques in their studies. "
f statistical methods are being used, then statisticians ought to be funded partners engaged in the research to insure as best we possibly can that the best quality science is being done," Wegman recommended, noting that "there are a host of fundamental statistical questions that beg answers in understanding climate dynamics."
In other words, Wegman believes that much of the climate science that has been done should be taken with a grain of salt -- although the studies may have been peer reviewed, the reviewers were often unqualified in statistics. Past studies, he believes, should be reassessed by competent statisticians and in future, the climate science world should do better at incorporating statistical know-how.
One place to start is with the American Meteorological Society, which has a committee on probability and statistics. "I believe it is amazing for a committee whose focus is on statistics and probability that of the nine members only two are also members of the American Statistical Association, the premier statistical association in the United States, and one of those is a recent PhD with an assistant-professor appointment in a medical school." As an example of the statistical barrenness of the climate-change world, Wegman cited the American Meteorological Association's 2006 Conference on Probability and Statistics in the Atmospheric Sciences, where only eight presenters out of 62 were members of the American Statistical Association.
While Wegman's advice -- to use trained statisticians in studies reliant on statistics -- may seem too obvious to need stating, the "science is settled" camp resists it. Mann's hockey-stick graph may be wrong, many experts now acknowledge, but they assert that he nevertheless came to the right conclusion.
To which Wegman, and doubtless others who want more rigourous science, shake their heads in disbelief. As Wegman summed it up to the energy and commerce committee in later testimony: "I am baffled by the claim that the incorrect method doesn't matter because the answer is correct anyway. Method Wrong + Answer Correct = Bad Science." With bad science, only true believers can assert that they nevertheless obtained the right answer.

THE CV OF A DENIER
Edward Wegman received his Ph.D. degree in mathematical statistics from the University of Iowa. In 1978, he went to the Office of Naval Research, where he headed the Mathematical Sciences Division with responsibility Navy-wide for basic research programs. He coined the phrase computational statistics, and developed a high-profile research area around this concept, which focused on techniques and methodologies that could not be achieved without the capabilities of modern computing resources and led to a revolution in contemporary statistical graphics. Dr. Wegman was the original program director of the basic research program in Ultra High Speed Computing at the Strategic Defense Initiative's Innovative Science and Technology Office. He has served as editor or associate editor of numerous prestigious journals and has published more than 160 papers and eight books.

Polar Bear bites reporter: proof of global warming
60 Minutes has never heard of bears getting stroppy with intruders. So when one polar bear - normally a cute little zoo animal - bites a reporter they conclude the reason.....of course...global warming. As they report:
"If you still have any lingering doubts about global warming, stick around. Weâre off to the Arctic, where Tara Brown found all the proof she needed that thereâs something drastically wrong with the worldâs weather. It came in the shape of a very large, very hungry polar bear - an angry predator, with us as its prey. Stranded in the middle of nowhere with a three-metre, 300kg bear on the attack is a frightening experience. Itâs also a graphic lesson in what happens when we mess with nature. As global temperatures rise, the ice cap melts and the polar bearsâ hunting grounds disappear. Now theyâre starving, desperate for food - so desperate even humans look appetising."
Case closed. However the Wall street journal thinks otherwise:
Apparently so, because there are in fact more polar bears in the world now than there were 40 years ago, as the nearby chart shows. The main threat to polar bears in recent decades has been from hunting, with estimates as low as 5,000 to 10,000 bears in the 1950s and 1960s. But thanks to conservation efforts, and some cross-border cooperation among the U.S., Canada and Russia, the best estimate today is that the polar bear population is 20,000 to 25,000.
It also turns out that most of the alarm over the polar bearâs future stems from a single, peer-reviewed study, which found that the bear population had declined by some 250, or 25%, in Western Hudson Bay in the last decade. But the polar bearâs range is far more extensive than Hudson Bay. A 2002 U.S. Geological Survey of wildlife in the Arctic Refuge Coastal Plain concluded that the ice bear populations âmay now be near historic highs.â One of the leading experts on the polar bear, Mitchell Taylor, the manager of wildlife resources for the Nunavut territory in Canada, has found that the Canadian polar bear population has actually increased by 25%âto 15,000 from 12,000 over the past decade.
Mr. Taylor tells us that in many parts of Canada, âpolar bears are very abundant and productive. In some areas, they are overly abundant. I understand that people not living in the North generally have difficulty grasping the concept of too many polar bears, but those who live here have a pretty good grasp of what that is like.â Those cuddly white bears are the Earthâs largest land carnivores.
But hey, I can understand 60 minutes on one side. My next door neighbours car hissed at me the other day, so naturally I thought cats were almost extinct too. 
BUT GET a LOAD of THIS! (http://www.numberwatch.co.uk/manmade.htm)
Yes, global warming really is man-made
When you are trying to troubleshoot an instrumentation system (whether it is in examining a PhD thesis or facing a major industrial crisis) there are, self-evidently, two vital areas you need to address:
1. The physical process of data acquisition
2. The computational process of Data handling
The central problem with data acquisition, now that data conversion is largely standardised through advances in electronics, is the housing and siting of sensors. Sometimes the problems are glaring, such as caking with mud or salt, but often they are more subtle and veiled. Particularly difficult are cases where instrumentation interacts with nearby systems (see appendix below for an example where an expensive court case was averted).
Data handling is an even greater problem, especially when âintuitiveâ or obscurely argued methods are implemented. Even if we discount the possibility of deliberate fraud, the power of the human subconscious to influence outcomes is a known but difficult to quantify hazard, especially in computer programs.
In considering data handling for climate monitoring in these terms, we now have the advantage of new information on siting and a description, though not a perspicuous one, of alterations made to original data.
We have long known that there have been examples of badly sited monitoring stations. The late John Daly showed seven years ago an example of bad siting, while, incidentally, raising the question of whether the surface record was as reliable as we were led to believe and proposing improvements of methodology. Dalyâs analysis has not only stood the test of time, but has been vindicated by recent developments. The satellite record continues to show little or no change while the surface record shows what is alleged to be a continued rising trend.
Here is the satellite record:
While here is the surface record:

In any other field (with the possible exception of epidemiology) such a discrepancy would result in an international conference to hammer out which version was correct. When you take into account that the difference is responsible for a multi-billion dollar international industry and a world-wide raft of draconian, liberty-crushing legislation, the silence is leaden.
The new development on the siting problem is that a systematic investigation has begun, involving the gathering of photographic evidence. The results so far are disturbing, even shocking.
This for example is a monitoring station at Wickenburg Arizona:
wickenburg_facing_se
The objects in the background are large air-conditioning units.
This is what John Daly wrote seven years ago about surface stations:
The only way surface data can be used with any confidence is to exclude all town/city and airport data - no exceptions. Only rural sites should be used, and by `ruralâ is meant strictly `greenfieldsâ sites where there is no urbanisation of any kind near the instrument. Even when greenfields stations are used, those which are technically supervised (eg. managed by scientists, marine authorities, the military etc.) should be treated with greater credibility than those from sheep stations, post offices and remote motels.
This total and obvious common sense has been completely ignored by the Climate Change Establishment. An industry turning over billions of dollars does nothing to ensure the integrity of the data on which it is based. The fee Al Gore gets for one hair-raising lecture alone would more than pay the annual salary of a warden to look after several such stations. âInsoucianceâ is an inadequate word for what appears to be a calculated dereliction. You might even suspect that they do not wish to know the truth.
So, that is the data acquisition â what about the processing? We can get a description of that from the horseâs mouth.
Mental warning lights flicker when the phrase âhigh-qualityâ appears in each of the first two sentences. It is redolent of the salesmanâs patter â never mind the quality, feel the width. There are other warning phrases such as âseveral adjustmentsâ or âempirical modelâ, enough to raise the hackles of an experienced PhD examiner. But any such reservations pale into insignificance compared with the effect of the overall adjustment.
Not only is the total adjustment sufficient to account for a large proportion of the claimed temperature rise, but as a graph against time it is just the right shape to give support to the claim that the rise is post-industrial. Such a coincidence is more than enough to make an old-fashioned scientist feel, to say the least, uncomfortable
Global warming is a new phenomenon in human affairs. Not only is it now a major religion, but it has an associated industrial complex of a wealth sufficient to give it unheard of political power throughout the world. It presides over a virtual monopoly of research funding. The tiny band of critics have to work without resources and under a continual barrage of abuse. Experience suggests that those collectors of photographs had better watch out for dirty tricks, now that they are making an impact.
Clearly, global warming is anthropogenic (man-made). It exists mainly in the human mind and is manufactured from two sources â careless data acquisition and dubious data processing.
Appendix
Example of a case of a system interaction problem (from Sorry, wrong number!)
I was consulted by a company who were having difficulties with their customers over an instrument within their equipment that was giving seriously faulty readings. The company was in legal dispute with the supplier of the instruments, who claimed that, when they were returned, they proved to be in perfect working order. I visited the client with two colleagues from my consultancy practice. When we opened the door of the cabinet the explanation was glaring. The instrument, which was not built to high standards of electromagnetic screening, shared its housing with large switchgear designed to control heavy machinery. Whenever a switch operated it induced large pulses of current within the instrument, causing it to misread. I advised that both parties were at fault in failing to communicate their specifications correctly and the case stayed out of court.
Moral: it is a necessary but not sufficient condition for a system to work correctly that all its subsystems work correctly.

How tragic for the late Alfred Nobel that science has abandoned the prize given in his memory and that politics has taken it over...
