Some perspective

I’m looking at the temperature record as read from this central Greenland ice core. It gives us about as close as we can come to a direct, experimental measurement of temperature at that one spot for the past 50,000 years. As far as I know, the data are not adjusted according to any fancy computer climate model or anything else like that. So what does it tell us about, say, the past 500 years? (the youngest datum is age=0.0951409 (thousand years before present) — perhaps younger snow doesn’t work so well?):

histo6

Well, whaddaya know — a hockey stick. In fact, the “blade” continues up in the 20th century at least another half a degree. But how long is the handle? How unprecedented is the current warming trend?

histo5

Yes, Virginia, there was a Medieval Warm Period, in central Greenland at any rate. But we knew that — that’s when the Vikings were naming it Greenland, after all. And the following Little Ice Age is what killed them off, and caused widespread crop failures (and the consequent burning of witches) across Europe. But was the MWP itself unusual?

histo4

Well, no — over the period of recorded history, the average temperature was about equal to the height of the MWP. Rises not only as high, but as rapid, as the current hockey stick blade have been the rule, not the exception.

histo3

In fact for the entire Holocene — the period over which, by some odd coincidence, humanity developed agriculture and civilization — the temperature has been higher than now, and the trend over the past 4000 years is a marked decline. From this perspective, it’s the LIA that was unusual, and the current warming trend simply represents a return to the mean. If it lasts.

histo2

From the perspective of the Holocene as a whole, our current hockeystick is beginning to look pretty dinky. By far the possibility I would worry about, if I were the worrying sort, would be the return to an ice age — since interglacials, over the past half million years or so, have tended to last only 10,000 years or so. And Ice ages are not conducive to agriculture.

histo1

… and ice ages have a better claim on being the natural state of Earth’s climate than interglacials. This next graph, for the longest period, we have to go to an Antarctic core (Vostok):

vostok

In other words, we’re pretty lucky to be here during this rare, warm period in climate history. But the broader lesson is, climate doesn’t stand still. It doesn’t even stand stay on the relatively constrained range of the last 10,000 years for more than about 10,000 years at a time.

The real scandal is in the CRU computer code

The emails and programmer comments have the advantage that anyone can understand them but -- as damning as the emails and comments are -- the real "smoking gun" evidence of fraud lies in the computer code used to produce the "statistics" that the CRU has published. They are not even "cherrypicked" statistics. They are a straight fraud. It's only by adding completely arbitrary and artificial "adjustments" to the data that they got their "hockey stick" -- thus making the CRU warming claims a complete and deliberate fraud -- an out-and-out hoax

It is fascinating to watch the mainstream media in America duck (and/or make excuses for) the greatest scam in modern history: the "science" behind man-made global warming. Even more entertaining, and far more enlightening, is to follow the analyses by the experts in computer programming of the recently disclosed methods used by the Climate Research Unit (CRU) from the University of East Anglia.

Most commentators in the media have been talking about the "REM" statements in the purloined e-mails and computer codes from the CRU [i]. True believers in anthropogenic global warming (AGW), especially those in the mainstream and "scientific" media, are pooh-poohing such words as "tricks" or "hide the decline" as interoffice slang that had no real impact on how the science was conducted.

But the real action (and the evidence for chicanery) is in the computer code obtained from the CRU. Our own computer guru Marc Sheppard, writing for American Thinker here and here, was one of the first to offer an accurate diagnosis of this fraudulent method of computer programming. Analyzing the code, as Marc has indicated in his work, is a complex business. As he pleads in one article, "please bear with me while I get a tad techie on you."

For the layman readers of American Thinker, I want to explain in a simple manner what went on in the construction of one piece of the controversial programming.

A bit of background: The cornerstone of the evidence for global warming presented by Al Gore and the AGW crowd was a notorious graph that became known as "the hockey stick graph." The graph is based on computer models that supposedly prove our planet has heated exponentially in the last half-century due to increasing amounts of man-made CO2 released into the atmosphere. Proponents further claim (and the computer models purport to show) that temperatures will continue to increase exponentially. The implication is that unless we drastically curtail human output of CO2, the "escalation" in temperature is going to get even worse even faster.

Turns out that these claims are absolutely false, and the computer models have been rigged.

Here is one version of the famous "hockey stick" graph:



Now that is scary [ii]! According to the now-debunked myth, global temperatures started going through the roof about sixty years ago. They will to continue to rise and bring unimaginable disaster. Except they haven't, and they probably won't.

Now to the CRU code that maintains these fictional monstrosities. Pay particular attention to the black line at the far right of the "hockey stick" in Graph 1. The black line starts at about 1900. (This is the same period of time addressed by the code we will examine.) The black line looks something like this very simplified version:



The x-axis (horizontal) shows time. The y-axis (vertical) shows temperature. In the last few decades, the temperature, according to AGW enthusiasts, has been climbing off the charts.

Marc Sheppard discovered and showed us this bit of programming taken from the CRU documents:

yrloc=[1400,findgen(19)*5.+1904]


valadj=[0.,0.,0.,0.,0.,-0.1,-0.25,-0.3,0.,-0.1,0.3,0.8,1.2,1.7,2.5,2.6,2.6,2.6,2.6,2.6]*0.75         ; fudge factor

The long string of bold numbers in the second set of brackets is the "fudge factor" applied (supposedly) to the raw data [iii]. This string of numbers "adjusts" the raw data from 1904 to 1994 in five-year increments. Here is what these nineteen numbers roughly look like on a simple graph (each bar below represents a number in bold above):


I have left a space between the bars that represent each number so the reader can compare the temperature line to the numbers from the program. Time is once again indicated by the x-axis (horizontal). Temperature is portrayed on the y-axis (vertical).

The numbers in the code indicate a degree of cheating that is actually much larger than I was able to show with the bars in Graph 3 [iv].

We can now prove beyond a shadow of a doubt that the hockey stick is an absolute ruse. The hockey stick graph cannot possibly be based on the actual data. (...Wherever and whatever that data might have been, that is. The CRU has admitted destroying the raw data.)

Even if the numbers in the program were not added to the aggregate temperatures (of each preceding period [v]), the numbers in the code plot like this:


Graph 4 this still looks an awful lot like the "hockey stick." In short, no matter how you read the code, it was designed to create a phony outcome.

But don't take my word for it. Computer experts everywhere are all over this particular con game, and many other deceptions, that came out of the CRU files.

Many years ago, I was an instructor in logic at the university level. Some of my best students were young people who planned on entering the new, exciting, rapidly expanding, and lucrative fields of computer science and computer programming.

A solid grasp of logic was, and still is, a great way to start an education in the computer sciences -- since computer programs are grounded in the basic rules and the syntax (sometimes slightly adjusted) of Boolean logic.

Computer programmers are often referred to as "nerds." In fact, they are meticulous; they have to be. Their programs don't work if they're lazy, or skips a step, or ignores the rules of logic and syntax that make computers do the job they are supposed to do. This is why competent computer programmers can spot a phony and a cheater from a mile away.

Writing the beautiful and logical structure of a computer code is almost like writing music. It is very easy for a skilled computer programmer to detect code that is "out of tune." Computer nerds are literally shouting about the audacity of the obviously contrived bit of code we have just examined. They are screaming in Germany, in America, and in lots of other places. Read the comments to these postings -- there are some good ones. (There are also efforts by true believers to justify the code. Try following the logic of the post in that last link.)

The bottom line is that if this kind of code were to be used by, say, an insurance actuary -- or by someone writing banking software or for tracking the stock market -- the programmer would immediately be fired...and probably face criminal prosecution.

The truth about the hockey stick hoax is slowly leaking out. New Zealand climate scientists released a similar doctored graph (for temperatures in New Zealand) that looked like this:


The scientists in New Zealand didn't destroy the raw data. (Oops.) The raw temperature data from New Zealand, when fed into a computer without a "fudge factor," looks like this:


In short, New Zealand has not heated up in the last 150 years. Not a bit. Zealous scientists promoting AGW (not the actual weather) caused the "warming" in New Zealand.  (Notice how closely the doctored Graph 5 from New Zealand resembles doctored Graph 1 and the code from the CRU we have examined.)

Any computer programmer worth his or her salt will tell you, "Garbage in, garbage out." The garbage in the AGW debate turns out to be the scientists who are writing fraudulent computer codes. Time to take out the trash.

Recalculation of climate data is the ONLY legitimate option



Approximately two weeks ago we all learned of e-mails written by those individuals supposedly considered to be the leaders in climate research that discussed manipulation of data and suppression of alternate positions. At the very least, these e-mails demonstrate an appearance of impropriety. Alternately, they may likely be evidence of outright fraud.

Investigations are planned or underway at the University of East Anglia and Penn State University. These investigations alone are insufficient. Science and politics are so deeply entangled that honest debate is practically impossible.

As an example, the UK Met Office is planning on re-examining 160 years of climate data to re-assure the public that the conclusions that warming is real are legit. But hasn't the planet been warming over the past 200 years on average having emerged from the Little Ice Age? Would not such an assessment simply re-validation of the same preconceived conclusion?

Met Office to re-examine 160 years of climate data (Times Online) Hat tip Climate Depot
The Met Office plans to re-examine 160 years of temperature data after admitting that public confidence in the science on man-made global warming has been shattered by leaked e-mails.

The new analysis of the data will take three years, meaning that the Met Office will not be able to state with absolute confidence the extent of the warming trend until the end of 2012.

The Met Office database is one of three main sources of temperature data analysis on which the UN’s main climate change science body relies for its assessment that global warming is a serious danger to the world. This assessment is the basis for next week’s climate change talks in Copenhagen aimed at cutting CO2 emissions.

The data from the past 1000 years must be assessed - all the data. Then a comparison of temperatures during the Medieval Warm Period with present day temperatures can show whether or not the warming seen at the end of the 20th century is necessarily a prelude to a catastrophe.

This week begins the UN's climate conference in Copenhagen. All of the data and conclusions based on that data are suspect. Until this situation can be clarified, there is no legitimate basis for the draconian measures planned to reduce energy consumption and lessen CO2 generation. Governments and individuals who say we need drastic action now are putting politics ahead of science. Scientific rigor and academic honesty require that the data be reanalyzed.

The new analysis cannot simply be a rehash of the same-ol same-ol. The data must be made public. Academia, government and private industry all have a stake and scientists from each of these areas should have access and be allowed to draw their own independent conclusions. The studies must be peer reviewed for the legitimacy and appropriateness of the method - not based on where the funding came from. If the science is sound it does not matter who is paying for it even if the conclusions are different.

The Copenhagen conference should take place as schedule. The agenda must be radically changed. The conference needs to become a working meeting in which the leaders of the conference publicly recognize that the science is not sound and place a moratorium on further actions until and unless the science can demonstrate that the changing climate in indeed being caused by human activity.

Proof of human cause is needed, not just the repetition of theory. The existence of global warming does not prove that it is man made. Proxy data for millions of years shows temperatures and CO2 concentrations far warmer and far cooler than exist today. Data from the Middle Ages and Little Ice Age show similar fluctuations during historical times. Recent temperature data shows natural cooling along with increasing CO2 concentrations. All natural sources must be accounted for and accurately represented.

The Copenhagen conference needs to be a turning point in which the UN IPCC recognizes that mistakes were made - possibly some deliberate. The IPCC must agree to a public accounting of what happened and who was involved. a follow-up conference should be schedule for 2012 or later after the data has been properly vetted.

Anything less would be illegitimate and truly does represent fraudulent behavior in light of the allegations that have come to light.

Another "trust us" claim

Not a single scientific fact is referred to below. This is bureacracy, not science

The Met Office has embarked on an urgent exercise to bolster the reputation of climate-change science after the furore over stolen e-mails.

More than 1,700 scientists have agreed to sign a statement defending the “professional integrity” of global warming research. They were responding to a round-robin request from the Met Office, which has spent four days collecting signatures. The initiative is a sign of how worried it is that e-mails stolen from the University of East Anglia are fuelling scepticism about man-made global warming at a critical moment in talks on carbon emissions.

One scientist said that he felt under pressure to sign the circular or risk losing work. The Met Office admitted that many of the signatories did not work on climate change.

John Hirst, the Met Office chief executive, and Julia Slingo, its chief scientist, wrote to 70 colleagues on Sunday asking them to sign “to defend our profession against this unprecedented attack to discredit us and the science of climate change”. They asked them to forward the petition to colleagues to generate support “for a simple statement that we . . . have the utmost confidence in the science base that underpins the evidence for global warming”.

Met Office reports on temperature changes draw on the work of the University of East Anglia’s Climatic Research Unit, from which the e-mails were hacked. Phil Jones, unit director, has agreed to stand down while an investigation takes place into claims that he manipulated data to exaggerate the warming trend and tried to block publication of alternative views.

One scientist told The Times he felt under pressure to sign. “The Met Office is a major employer of scientists and has long had a policy of only appointing and working with those who subscribe to their views on man-made global warming,” he said.

Professor Slingo denied that the Met Office had put anyone under pressure. “The response has been absolutely spontaneous. As a scientist you sign things you agree with, not because you are worried about what the Met Office might think of you,” she said.

The 1,700 signatories, a fraction of the research scientists working in Britain, include Sir John Houghton, former chairman of the science working group of the Intergovernmental Panel on Climate Change, Sir Brian Hoskins, head of the Grantham Institute at Imperial College, and Professor Lord Hunt of Chesterton, a climate scientist at University College London.

Professor Slingo said the statement was carefully worded to avoid claiming all climate scientists were beyond reproach. It says the evidence for man-made global warming is “deep and extensive” and comes from “decades of painstaking and meticulous research by many thousands of scientists across the world who adhere to the highest levels of professional integrity”.

Benny Peiser, of the Global Warming Policy Foundation, which claims man-made climate change has been exaggerated, said the petition showed that the Met Office was rattled.

Surprise, Surprise, Many Scientists Disagree On Global Warming

There is hardly unanimity among scientists about global warming or mankind's role in producing it. But you wouldn't know it if you just listened to the Obama administration.

As the Climate-gate controversy continues to grow, amid charges of hiding and manipulating data, and suppressing research by academics who challenge global warming, there is one oft-repeated defense: other independent data-sets all reach the same conclusions. "I think everybody is clear on the science. I think scientists are clear on the science ... I think that this notion that there's some debate . . . on the science is kind of silly," said President Obama's Press Secretary, Robert Gibbs, when asked about the president's response to the controversy on Monday. Despite the scandal, Britain's Met, the UK’s National Weather Service, claims: "we remain completely confident in the data. The three independent data sets show a strong correlation is highlighting an increase in global temperatures."

But things are not so clear. It is not just the University of East Anglia data that is at question. There are about 450 academic peer-reviewed journal articles questioning the importance of man-made global warming. The sheer number of scientists rallying against a major intervention to stop carbon dioxide is remarkable. In a petition, more than 30,000 American scientists are urging the U.S. government to reject the Kyoto treaty. Thus, there is hardly the unanimity among scientists about global warming or mankind's role in producing it. But even for the sake of argument, assuming that there is significant man-made global warming, many academics argue that higher temperatures are actually good. Higher temperatures increase the amount of land to grow food, increase biological diversity, and improve people's health. Increased carbon dioxide also promotes plant growth.

Let's take the issue of data. The three most relied-on data series used by the United Nation's Intergovernmental Panel on Climate Change assessment report came from the University of East Anglia, NASA, and the British Met Office. As noted in my previous piece for the Fox Forum, the problem of secretiveness is hardly limited to the University of East Anglia. NASA also refuses to give out its data. NASA further refuses to explain mysterious changes in whether the warmest years were in the 1930s or this past decade. The British Met office, too, has been unable to release its data and just announced its plans to begin a three-year investigation of its data since all of its land temperatures data were obtained from the University of East Anglia (ocean temperatures were collected separately), though there are signs that things might be speeded up.

Neither the Climate Research Unit (CRU) at the University of East Anglia nor the British Met are able to provide their raw data to other research scientists because of the confidentiality agreements that Professor Phil Jones at CRU entered into. Unfortunately, Jones did not keep records of those agreements and, according to the British Met, can neither identify the countries with the confidentiality agreements nor provide the agreements. Earlier this year the British Met wrote the following to Steve McIntyre at Climate Audit:

"Some of the information was provided to Professor Jones on the strict understanding by the data providers that this station data must not be publicly released and it cannot be determined which countries or stations data were given in confidence as records were not kept."

A press spokesman for the British Met, John Hammond, confirmed this statement in a telephone conversation on Monday to FoxNews.com. But the claimed confidentiality restrictions have hardly been followed consistently. When asked why the University of East Anglia was allowed to release the data to the Met but not to other academics, Mr. Hammond e-mailed back: "This is a question for the UEA." Unfortunately, however, neither the University of East Anglia nor anyone associated with the CRU was willing to answer any questions about the climate research conducted at the university.

But why would countries want confidentiality agreements on decades old data that they are providing? "Climate data continues to have value so long as it is commercially confidential," Mr. Hammond says. But when pushed for evidence that this was in fact the concerns that countries had raised, Mr. Hammond said: "Although I do not have evidence to hand at the moment, some nations, especially in Africa for example, believe that the information does have commercial value." Earlier, in July, the Met had raised a different issue -- that scientists in other countries would be less willing to share their scientific research if the Met could be expected to pass on the data to others.

However, professional meterologists are unimpressed by the claimed reasons for confidentiality. "Research data used as the basis for scientific research needs to be disclosed if other scientists are to be able to verify the work of others," Mike Steinberg, Senior Vice President, AccuWeather, told FoxNews.com. In addition, while the data access may be restricted in some countries because they sell data and forecasts, that doesn't explain why the data isn't released for all other countries.

It is not just the University of East Anglia that has been accused of massaging the data (what they called creating "value added" data). Recently, New Zealand has also had its temperature series from the National Institute of Water and Atmospheric Research (NIWA) challenged. Still the NIWA continues to insist that the "Warming over New Zealand through the past is unequivocal." Indeed, the institute claims that the New Zealand warming trend was 50 percent higher than the global average. But the difference in graphs between what NIWA produced after massaging the data and what the original raw data showed was truly remarkable and can be seen here. As the Climate Science Coalition of New Zealand charged: "The shocking truth is that the oldest readings have been cranked way down and later readings artificially lifted to give a false impression of warming, as documented below." Similar concerns have also been raised about Australian temperature data.

Global warming advocates may believe that if they just keep shouting that everyone agrees with them, they will be able to enact their far-reaching regulations before everyone catches on. With President Obama's -- and the Democrats' -- fondness for more spending and increased regulations, our hope may have to rest with India and China to finally bring the Copenhagen conference to its senses.

Climate Liars: Are Pacific Islands Being Swamped From Rising Seas? Only If You Believe Political Hacks @ Copenhagen

Read here. Despite the embarrassment of the Climategate data fraud and conspiracy scandal, it has not stopped the politically motivated and financially hungry at Copenhagen from making every effort to lie and mislead the public about the actual global climate condition. As an example, a favorite lie is to claim that the islands of the Pacific are being inundated by the rising seas caused by global "warming." It's a whopper of a lie, which the mainstream press repeats reflexively, without checking an iota of data concerning the bogus claim. Below is a chart for two of those islands.

The facts: The seas fluctuate up/down over time, rarely exceeding a one-tenth meter change. The sea level changes are recorded by state-of-the-art equipment, installed and maintained by the Australian government. The chart is from the latest 2008 survey.

Big Oil Behind Copenhagen Climate Scam

Shell Oil and British Petroleum express their vehement support for a global carbon tax in “Copenhagen Communiqué”

The big irony behind top globalists descending on Copenhagen in luxury private jets and stretch limos is not just the fact that their own behavior completely contradicts their self-righteous hyperbole about CO2 emissions, but that their propaganda is vehemently supported by the very same big oil interests they accuse climate skeptics of pandering to.

Probably one of the most flagrant examples of climate cronyism to emerge from the climategate scandal were emails in which CRU scientists, the body that provides much of the foundational global warming data for the UN IPCC, discuss how they conducted meetings with Shell Oil in order to enlist them as a “strategic partner” while getting them to bankroll pro-man made global warming research.

The emails reveal that the CRU was also trying to get money from oil giants British Petroleum and Exxon-Mobil, under its former identity as Esso.

“Now who is the shill for Big Oil again?” asks Anthony Watts. “Next time somebody brings up that ridiculous argument about skeptics, show them this.”

A “Copenhagen Communiqué” put out by leaders of over 500 global corporations in advance of this week’s summit calls for drastic measures on behalf of developed countries to “de-carbonise their economies” – a move that would completely devastate living standards and lead to gargantuan levels of unemployment.

The communiqué also demands that a global carbon tax be implemented via a carbon trading system. Bear in mind that the very people calling for such a system are the same people who will benefit from it to the tune of billions, as we shall explore later.

The statement calls for, “Measures to deliver a robust global greenhouse gas emissions market in order to provide the most effective, efficient and equitable emission reductions. It would be comprised of a growing series of national or regional “cap-and-trade” markets linked together, in which the “caps” are brought down in line with the targets that have been adopted for emission reduction.” The document also states that CO2 emissions need to be reduced by a staggering 50-85% by 2050, a process that would return humanity to a near stone age level of development.

And who are the radicals calling for such severe measures in the name of fighting the evil life giving gas that humans exhale and plants breathe? Greenpeace? Al Gore? Namely – James Smith, chairman of UK Shell Oil, Tony Hayward, Group Chief Executive, British Petroleum, along with hundreds of other global corporate giants, many of whom are directly tied in with big oil, and central banks who, far from bankrolling climate change skeptics, are directly invested in the scam of human-induced global warming.

A common charge leveled against global warming skeptics is that they are on the payroll of transnational oil companies, when in fact the opposite is true, oil companies are amongst the biggest promoters of climate change propaganda, emphasized recently by Exxon Mobil’s call for a global carbon tax. According to Exxon Mobil chief executive Rex Tillerson, the cap and trade nightmare being primed for passage in the Senate doesn’t go far enough – Tillerson wants a direct tax on carbon dioxide emissions, essentially a tax on breathing since we all exhale this life-giving gas.

In a speech earlier this year, Tillerson brazenly called out the cap and trade agenda for what it was, an effort to impose a carbon tax camouflaged only by a slick sales pitch and deceptive rhetoric. “It is easier and more politically expedient to support a cap-and-trade approach, because the public will never figure out where it is hitting them,” said Tillerson. “They will just know they hurt somewhere in their pocketbook,” he added, pointing out that he disagreed with this convoluted method of introducing a carbon tax, arguing instead that it would be more successful to openly propose a straight carbon tax.

Tillerson firmly expressed Exxon’s support for climate change alarmists in stating, “I firmly believe it is not too late for Congress to consider a carbon tax as the better policy approach for addressing the risks of climate change.” Exxon’s push for a carbon tax was subsequently restated by its vice president for public affairs Ken Cohen, who told a conference call that he wants a climate policy that creates “certainty and predictability, which is why we advocate a carbon tax.”
