Global Warming: OSU Scientist Reports Warming A Natural Cycle – CO2 as byproduct not “climate driver”
VIEWPOINT: GLOBAL WARMING NATURAL, MAY END WITHIN 20 YEARS
COLUMBUS, Ohio — Global warming is a natural geological process that could begin to reverse itself within 10 to 20 years, predicts an Ohio State University researcher.
The researcher suggests that atmospheric carbon dioxide — often thought of as a key “greenhouse gas” — is not the cause of global warming. The opposite is most likely to be true, according to Robert Essenhigh, E.G. Bailey Professor of Energy Conservation in Ohio State’s Department of Mechanical Engineering. It is the rising global temperatures that are naturally increasing the levels of carbon dioxide, not the other way around, he says.
Many people blame global warming on carbon dioxide sent into the atmosphere from burning fossil fuels in man-made devices such as automobiles and power plants. Essenhigh believes these people fail to account for the much greater amount of carbon dioxide that enters — and leaves — the atmosphere as part of the natural cycle of water exchange from, and back into, the sea and vegetation.
“Many scientists who have tried to mathematically determine the relationship between carbon dioxide and global temperature would appear to have vastly underestimated the significance of water in the atmosphere as a radiation-absorbing gas,” Essenhigh argues. “If you ignore the water, you’re going to get the wrong answer.”
How could so many scientists miss out on this critical bit of information, as Essenhigh believes? He said a National Academy of Sciences report on carbon dioxide levels that was published in 1977 omitted information about water as a gas and identified it only as vapor, which means condensed water or cloud, which is at a much lower concentration in the atmosphere; and most subsequent investigations into this area evidently have built upon the pattern of that report.
For his hypothesis, Essenhigh examined data from various other sources, including measurements of ocean evaporation rates, man-made sources of carbon dioxide, and global temperature data for the last one million years.
He cites a 1995 report from the Intergovernmental Panel on Climate Change (IPCC), a panel formed by the World Meteorological Organization and the United Nations Environment Programme in 1988 to assess the risk of human-induced climate change. In the report, the IPCC wrote that some 90 billion tons of carbon as carbon dioxide annually circulate between the earth’s ocean and the atmosphere, and another 60 billion tons exchange between the vegetation and the atmosphere. (Total of 150 billion tons produced by the earth naturally).
Compared to man-made sources’ emission of about 5 to 6 billion tons per year, the natural sources would then account for more than 95 percent of all atmospheric carbon dioxide, Essenhigh said. (Of the total of 156 billion tons of CO2 to pass through the earth’s atmosphere on an anuual basis – less than 6 billion is produced by man)
“At 6 billion tons, humans are then responsible for a comparatively small amount – less than 5 percent – of atmospheric carbon dioxide,” he said. “And if nature is the source of the rest of the carbon dioxide, then it is difficult to see that man-made carbon dioxide can be driving the rising temperatures. In fact, I don’t believe it does.”
Some scientists believe that the human contribution to carbon dioxide in the atmosphere, however small, is of a critical amount that could nonetheless upset Earth’s environmental balance. But Essenhigh feels that, mathematically, that hypothesis hasn’t been adequately substantiated.
Here’s how Essenhigh sees the global temperature system working: As temperatures rise, the carbon dioxide equilibrium in the water changes, and this releases more carbon dioxide into the atmosphere. According to this scenario, atmospheric carbon dioxide is then an indicator of rising temperatures — not the driving force behind it.
Essenhigh attributes the current reported rise in global temperatures to a natural cycle of warming and cooling.
He examined data that Cambridge University geologists Nicholas Shackleton and Neil Opdyke reported in the journal Quaternary Research in 1973, which found that global temperatures have been oscillating steadily, with an average rising gradually, over the last one million years — long before human industry began to release carbon dioxide into the atmosphere. Opdyke is now at the University of Florida.
According to Shackleton and Opdyke’s data, average global temperatures have risen less than one degree in the last million years, though the amplitude of the periodic oscillation has now risen in that time from about 5 degrees to about 10 degrees, with a period of about 100,000 years.
“Today, we are simply near a peak in the current cycle that started about 25,000 years ago,” Essenhigh explained.
As to why highs and lows follow a 100,000 year cycle, the explanation Essenhigh uses is that the Arctic Ocean acts as a giant temperature regulator, an idea known as the “Arctic Ocean Model.” This model first appeared over 30 years ago and is well presented in the 1974 book Weather Machine: How our weather works and why it is changing, by Nigel Calder, a former editor of New Scientist magazine.
According to this model, when the Arctic Ocean is frozen over, as it is today, Essenhigh said, it prevents evaporation of water that would otherwise escape to the atmosphere and then return as snow. When there is less snow to replenish the Arctic ice cap, the cap may start to shrink. That could be the cause behind the retreat of the Arctic ice cap that scientists are documenting today, Essenhigh said.
As the ice cap melts, the earth warms, until the Arctic Ocean opens again. Once enough water is available by evaporation from the ocean into the atmosphere, snows can begin to replenish the ice cap. At that point, the Arctic ice begins to expand, the global temperature can then start to reverse, and the earth can start re-entry to a new ice age.
According to Essenhigh’s estimations, Earth may reach a peak in the current temperature profile within the next 10 to 20 years, and then it could begin to cool into a new ice age.
“If there are flaws in these propositions, I’m listening,” he wrote in his Chemical Innovation paper. “But if there are objections, let’s have them with the numbers.”

Climategate U-turn as scientist at centre of row admits: There has been no global warming since 1995
Data for vital ‘hockey stick graph’ has gone missing
There has been no global warming since 1995
Warming periods have happened before – but NOT due to man-made changes
The data crucial to the famous ‘hockey stick graph’ used by climate change advocates to support the theory, may have gone missing.
Professor Jones also conceded the possibility that the world was warmer in medieval times than now – suggesting global warming may not be a man-made phenomenon.
And he said that for the past 15 years there has been no ‘statistically significant’ warming.
The raw data, collected from hundreds of weather stations around the world and analysed by his unit, has been used for years to bolster efforts by the United Nation’s Intergovernmental Panel on Climate Change to press governments to cut carbon dioxide emissions.

Schools close as South starts getting rare snow
PENSACOLA, Fla. – Schools were shuttered and flights canceled across the South on Friday as snow began falling, bringing a rare white landscape that could stretch into areas that haven’t seen snow in a decade — or longer.
Winter storm warnings spanned the Gulf Coast states early Friday as the snow crawled east out of Texas, where it left the Dallas area with more than a foot of snow, nearly 200 traffic accidents and hundreds of canceled flights. Snow, ice and sleet closed parts of Interstate 49 in central Louisiana early Friday.
Areas of northern and central Louisiana got 5 inches or more of snow before dawn Friday. In southern Mississippi, 3 inches had fallen in McComb and 2 inches were on the ground in Tylertown. One to 3 inches of snow had fallen in Jackson. Snow also began falling in southern Alabama, where up to 5 inches was expected.
Predictions of an inch of snow was enough to close schools in the Florida Panhandle, while classes also were canceled in parts of Alabama.
In Pensacola, Fla., heavy rain fell early Friday as the area braced for possible snow.
Even a Starbucks in nearby Gulf Breeze delayed opening. Jim Pavelic, a retiree from Chicago who relocated to Florida, made his way to the door of the store around 6:20 a.m. and read the sign noting the store would open late “due to the unprecedented weather patterns.”
Pavelic couldn’t believe it.
“You cannot even get a cup of coffee and it’s raining,” he said, laughing. “At least I don’t need a snow shovel.”
Several oceanside communities in South Carolina including Charleston — which hasn’t seen recorded snowfall since January 2000 — could see between 2 and 4 inches of snow, said Jonathan Lamb, a National Weather Service meteorologist based in Charleston.
And as much as 3 inches could hit Savannah, Ga., where snow was last traced in February 1996 — “and that was only 0.2 inches,” Lamb said. It’s been two decades since Georgia’s oldest city had any notable accumulation, with 3.6 inches falling in December 1989. Normally, temperatures in February don’t dip below 41 degrees.
“There’s no doubt this is a significant event for us,” Lamb said.
Highway patrol troopers in Texas, Alabama and several other states warned of treacherous morning commutes. Dallas police responded to 41 major traffic accidents and 132 minor ones Thursday, though no serious injuries were reported.
Nearly 1,100 flights were canceled systemwide by Fort Worth, Texas-based American Airlines and American Eagle airlines Thursday — about 30 percent of American’s daily flight schedule, said American spokesman Steve Schlachter. Of those, 305 were flights from Dallas-Fort Worth.
The snowfall made this the snowiest winter in the Dallas-Fort Worth area in 32 seasons.
In Atlanta, Delta Air Lines canceled 400 flights for Friday in anticipation of as much as 2 inches of snow expected in the region. AirTran also thinned its schedule, announcing Thursday plans to cut 32 of its flights on Friday because of the threat of snow. That included flights in and out of Atlanta.
More Than 700 International Scientists Dissent Over Man-Made Global Warming Claims
Washington, DC: Fifty-nine additional scientists from around the world have been added to the U.S. Senate Minority Report of dissenting scientists, pushing the total to over 700 skeptical international scientists – a dramatic increase from the original 650 scientists featured in the initial December 11, 2008 release. The 59 additional scientists added to the 255-page Senate Minority report since the initial release 13 ½ weeks ago represents an average of over four skeptical scientists a week. This updated report – which includes yet another former UN IPCC scientist – represents an additional 300 (and growing) scientists and climate researchers since the initial report’s release in December 2007.
The over 700 dissenting scientists are now more than 13 times the number of UN scientists (52) who authored the media-hyped IPCC 2007 Summary for Policymakers. The 59 additional scientists hail from all over the world, including Japan, Italy, UK, Czech Republic, Canada, Netherlands, the U.S. and many are affiliated with prestigious institutions including, NASA, U.S. Navy, U.S. Defense Department, Energy Department, U.S. Air Force, the Philosophical Society of Washington (the oldest scientific society in Washington), Princeton University, Tulane University, American University, Oregon State University, U.S. Naval Academy and EPA.
The explosion of skeptical scientific voices is accelerating unabated in 2009. A March 14, 2009 article in the Australian revealed that Japanese scientists are now at the forefront of rejecting man-made climate fears prompted by the UN IPCC.
Prominent Japanese Geologist Dr. Shigenori Maruyama, a professor at the Tokyo Institute of Technology’s Department of Earth and Planetary Sciences who has authored more than 125 scientific publications, said in March 2009 that “there was widespread skepticism among his colleagues about the IPCC’s fourth and latest assessment report that most of the observed global temperature increase since the mid-20th century ‘is very likely due to the observed increase in anthropogenic greenhouse gas concentrations.” Maruyama noted that when this question was raised at a Japan Geoscience Union symposium last year, ‘the result showed 90 per cent of the participants do not believe the IPCC report.” [Also See: The prestigious International Geological Congress, dubbed the geologists’ equivalent of the Olympic Games, was held in Norway in August 2008 and prominently featured the voices of scientists skeptical of man-made global warming fears. [ See: Skeptical scientists overwhelm conference: ’2/3 of presenters and question-askers were hostile to, even dismissive of, the UN IPCC’ & see full reports here & here –More analyses of recent developments see report’s introduction here. ]
“I do not find the supposed scientific consensus among my colleagues,” noted Earth Scientist Dr. Javier Cuadros on March 3, 2009. Cuadros, of the UK Natural History Museum, specializes in Clay Mineralogy and has published more than 30 scientific papers.
Award-Winning Princeton University Physicist Dr. Robert H. Austin, who has published 170 scientific papers and was elected a member of the U.S. National Academy of Sciences, lamented the current fears over global warming.
“Unfortunately, Climate Science has become Political Science…It is tragic that some perhaps well-meaning but politically motivated scientists who should know better have whipped up a global frenzy about a phenomena which is statistically questionable at best,” Austin told the minority staff on the Environment and Public Works Committee on March 2, 2009.
‘Could turn the climate change world upside down’
The rise in skeptical scientists are responding not only to an increase in dire “predictions” of climate change, but also a steady stream of peer-reviewed studies, analyses, real world data, and inconvenient developments have further cast doubts on the claims of man-made global warming fear activists. The latest peer-reviewed study in Geophysical Research Letters is being touted as a development that “could turn the climate change world upside down.” The study finds that the “Earth is undergoing natural climate shift.” The March 15, 2009 article in WISN.com details the research of Dr. Anastasios Tsonis of the University of Wisconsin-Milwaukee. “We realized a lot of changes in the past century from warmer to cooler and then back to warmer were all natural,” Tsonis said. “I don’t think we can say much about what the humans are doing,” he added.
Tsonis further added: “The temperature has flattened and is actually going down. We are seeing a new shift towards cooler temperatures that will last for probably about three decades.” [ See also: Peer-Reviewed Study Finds Global Warming could stop ‘for up to 30 years! Warming ‘On Hold?…’Could go into hiding for decades’ study finds – Discovery.com – March 2, 2009 ]
Climate ‘primarily being driven by natural forcing mechanisms’
Climatologist and Paloeclimate researcher Dr. Diane Douglas, who has authored or edited over 200 technical reports, also declared natural factors are dominating climate, not CO2. “The recent ‘panic’ to control GHG (greenhouse gas) emissions and billions of dollars being dedicated for the task has me deeply concerned that US, and other countries are spending precious global funds to stop global warming, when it is primarily being driven by natural forcing mechanisms,” Douglas, who is releasing a major new paper she authored that will be presented at a UNESCO conference in Ghent, Belgium on March 20, 2009, told the minority staff on the Environment and Public Works Committee on March 10, 2009.
Retired Award Winning NASA Atmospheric Scientist Dr. William W. Vaughan, recipient of the NASA Exceptional Service Medal, a former Division Chief of NASA’s Marshall Space Flight Center and author of more than 100 refereed journal articles, monographs, and papers, also now points to natural causes of recent climate changes. “The cause of these global changes is fundamentally due to the Sun and its effect on the Earth as it moves about in its orbit. Not from man-made activities,” Vaughan told the minority staff on the Environment and Public Works Committee on February 6, 2009.
Geology Professor Uberto Crescenti of the University G.d’Annunzio in Italy, the past president of the Society of Italian Geologists also agrees that nature, not mankind is ruling the climate. “I think that climatic changes have natural causes according to geological data…I am very glad to sign the U.S. Senate’s report of scientists against the theory of man-made global warming,” Crescenti told the minority staff on the Environment and Public Works Committee on January 15, 2009.
UN IPCC Scientist Dr. Steven M. Japar, a PhD atmospheric chemist who was part of Intergovernmental Panel on Climate Change’s (IPCC) Second (1995) and Third (2001) Assessment Reports, and has authored 83 peer-reviewed publications and in the areas of climate change, atmospheric chemistry, air pollutions and vehicle emissions, challenged the IPCC’s climate claims.
“Temperature measurements show that the [climate model-predicted mid-troposphere] hot zone is non-existent. This is more than sufficient to invalidate global climate models and projections made with them!” Japar told the minority staff on the Environment and Public Works Committee on January 7, 2009.
Mathematical Physicist Dr. Frank Tipler, professor at Tulane University who has authored 58 peer-reviewed publications and five books, ridiculed man-made climate claims. “Whether the ice caps melt, or expand — whatever happens — the AGW (anthropogenic global warming) theorists claim it confirms their theory. A perfect example of a pseudo-science like astrology,” Tipler wrote on December 22, 2008.
Botanist Dr. David Bellamy, a famed UK environmental campaigner, former lecturer at Durham University, and host of a popular UK TV series on wildlife, says the international promotion of man-made global warming fears are nearing their end. (Note: Bellamy was in the original 2007 U.S. Senate report.] “The science has, quite simply, gone awry. In fact, it’s not even science any more, it’s anti-science,” Bellamy, who used to believe in man-made warming, declared on November 5, 2008.
Chemist Dr. Mark L. Campbell, a professor of chemistry at the U.S. Naval Academy in Annapolis, MD, who has published numerous studies in the Journal of the American Chemical Society on topics such as methane, squarely blames the media for promoting unfounded climate fears. “The sky is not burning, and to claim that it is amounts to journalistic malpractice…the press only promotes the global warming alarmists and ignores or minimizes those of us who are skeptical,” Chapman wrote on January 13, 2009.
“Scientists across the globe are catching on — global warming is not real science. There is a sucker born every minute who believes in it, and Al Gore is playing the role of P.T. Barnum,” Chemist Max S. Strozier declared on December 22, 2009 in an email to the minority staff of the Environment and Public Works Committee. Strozier spent 26 years specializing in chemical laboratory analysis, served as a U.S. Department of Defense aerospace chemist and is a former lecturer at San Jose State University and the University of Texas.

OPEN LETTER TO THE CONGRESS OF THE UNITED STATES: YOU ARE BEING DECEIVED ABOUT GLOBAL WARMING
You have recently received an Open Letter from the Woods Hole Research Center, exhorting you to act quickly to avoid global disaster. The letter purports to be from independent scientists, but that Center is the former den of the President’s science advisor, John Holdren, and is far from independent. This is the same science advisor who has given us predictions of “almost certain” thermonuclear war or eco-catastrophe by the year 2000, and many other forecasts of doom that somehow never seem to arrive on time.
The facts are:
The sky is not falling; the Earth has been cooling for ten years, without help. The present cooling was NOT predicted by the alarmists’ computer models, and has come as an embarrassment to them.
The finest meteorologists in the world cannot predict the weather two weeks in advance, let alone the climate for the rest of the century. Can Al Gore? Can John Holdren? We are flooded with claims that the evidence is clear, that the debate is closed, that we must act immediately, etc, but in fact
THERE IS NO SUCH EVIDENCE; IT DOESN’T EXIST.
The proposed legislation would cripple the US economy, putting us at a disadvantage compared to our competitors. For such drastic action, it is only prudent to demand genuine proof that it is needed, not guesswork, and not false claims about the state of the science.
DEMAND PROOF, NOT CONSENSUS
Finally, climate alarmism pays well. Many alarmists are profiting from their activism. There are billions of dollars floating around for the taking, and being taken.

World misled over Himalayan glacier meltdown
A WARNING that climate change will melt most of the Himalayan glaciers by 2035 is likely to be retracted after a series of scientific blunders by the United Nations body that issued it.
Two years ago the Intergovernmental Panel on Climate Change (IPCC) issued a benchmark report that was claimed to incorporate the latest and most detailed research into the impact of global warming. A central claim was the world’s glaciers were melting so fast that those in the Himalayas could vanish by 2035.
In the past few days the scientists behind the warning have admitted that it was based on a news story in the New Scientist, a popular science journal, published eight years before the IPCC’s 2007 report.
It has also emerged that the New Scientist report was itself based on a short telephone interview with Syed Hasnain, a little-known Indian scientist then based at Jawaharlal Nehru University in Delhi.
Hasnain has since admitted that the claim was “speculation” and was not supported by any formal research. If confirmed it would be one of the most serious failures yet seen in climate research. The IPCC was set up precisely to ensure that world leaders had the best possible scientific advice on climate change.
Professor Murari Lal, who oversaw the chapter on glaciers in the IPCC report, said he would recommend that the claim about glaciers be dropped: “If Hasnain says officially that he never asserted this, or that it is a wrong presumption, than I will recommend that the assertion about Himalayan glaciers be removed from future IPCC assessments.”
The IPCC’s reliance on Hasnain’s 1999 interview has been highlighted by Fred Pearce, the journalist who carried out the original interview for the New Scientist. Pearce said he rang Hasnain in India in 1999 after spotting his claims in an Indian magazine. Pearce said: “Hasnain told me then that he was bringing a report containing those numbers to Britain. The report had not been peer reviewed or formally published in a scientific journal and it had no formal status so I reported his work on that basis.
“Since then I have obtained a copy and it does not say what Hasnain said. In other words it does not mention 2035 as a date by which any Himalayan glaciers will melt. However, he did make clear that his comments related only to part of the Himalayan glaciers. not the whole massif.”
The New Scientist report was apparently forgotten until 2005 when WWF cited it in a report called An Overview of Glaciers, Glacier Retreat, and Subsequent Impacts in Nepal, India and China. The report credited Hasnain’s 1999 interview with the New Scientist. But it was a campaigning report rather than an academic paper so it was not subjected to any formal scientific review. Despite this it rapidly became a key source for the IPCC when Lal and his colleagues came to write the section on the Himalayas.
When finally published, the IPCC report did give its source as the WWF study but went further, suggesting the likelihood of the glaciers melting was “very high”. The IPCC defines this as having a probability of greater than 90%.
The report read: “Glaciers in the Himalaya are receding faster than in any other part of the world and, if the present rate continues, the likelihood of them disappearing by the year 2035 and perhaps sooner is very high if the Earth keeps warming at the current rate.”
However, glaciologists find such figures inherently ludicrous, pointing out that most Himalayan glaciers are hundreds of feet thick and could not melt fast enough to vanish by 2035 unless there was a huge global temperature rise. The maximum rate of decline in thickness seen in glaciers at the moment is 2-3 feet a year and most are far lower.
Professor Julian Dowdeswell, director of the Scott Polar Research Institute at Cambridge University, said: “Even a small glacier such as the Dokriani glacier is up to 120 metres [394ft] thick. A big one would be several hundred metres thick and tens of kilometres long. The average is 300 metres thick so to melt one even at 5 metres a year would take 60 years. That is a lot faster than anything we are seeing now so the idea of losing it all by 2035 is unrealistically high.”
Some scientists have questioned how the IPCC could have allowed such a mistake into print. Perhaps the most likely reason was lack of expertise. Lal himself admits he knows little about glaciers. “I am not an expert on glaciers.and I have not visited the region so I have to rely on credible published research. The comments in the WWF report were made by a respected Indian scientist and it was reasonable to assume he knew what he was talking about,” he said.
Rajendra Pachauri, the IPCC chairman, has previously dismissed criticism of the Himalayas claim as “voodoo science”.
Last week the IPCC refused to comment so it has yet to explain how someone who admits to little expertise on glaciers was overseeing such a report. Perhaps its one consolation is that the blunder was spotted by climate scientists who quickly made it public.
The lead role in that process was played by Graham Cogley, a geographer from Trent University in Ontario, Canada, who had long been unhappy with the IPCC’s finding.
He traced the IPCC claim back to the New Scientist and then contacted Pearce. Pearce then re-interviewed Hasnain, who confirmed that his 1999 comments had been “speculative”, and published the update in the New Scientist.
Cogley said: “The reality, that the glaciers are wasting away, is bad enough. But they are not wasting away at the rate suggested by this speculative remark and the IPCC report. The problem is that nobody who studied this material bothered chasing the trail back to the original point when the claim first arose. It is ultimately a trail that leads back to a magazine article and that is not the sort of thing you want to end up in an IPCC report.”
Pearce said the IPCC’s reliance on the WWF was “immensely lazy” and the organization need to explain itself or back up its prediction with another scientific source. Hasnain could not be reached for comment.
The revelation is the latest crack to appear in the scientific concensus over climate change. It follows the so-called climate-gate scandal, where British scientists apparently tried to prevent other researchers from accessing key date. Last week another row broke out when the Met Office criticised suggestions that sea levels were likely to rise 1.9m by 2100, suggesting much lower increases were likely.
