Climate Change Revisited
By Doug Hornig

In March 2004, we ran an article on a Pentagon-commissioned study on the possibility of abrupt and drastic climate change, such as happened 12,000 years ago when, according to estimates, the average global temperature rose by seven degrees in only twenty years and put a decisive end to the most recent ice age.

The result of the study, a brief paper titled, An Abrupt Climate Change Scenario and Its Implications for United States National Security, pushed certain computer models to their extreme, at which a sudden rise in global temperature results in a shutting down of the Gulf Stream and, counterintuitively, colder conditions for much of the planet.

That, of course, is just one projection among many. Other researchers have modeled quite different futures, with conditions both more and less dire.

In the past two and a half years, the debate over global warming, its potential effects, and (especially) the human role in bringing it about, has only intensified—with Al Gore’s widely seen movie, An Inconvenient Truth, and his packed public lectures leading the way. Thus this seemed like an opportune time for us to revisit the topic.

The central question, it would seem, has been answered. Are we in a period of global warming?

Yes, sort of.

As always, the devil is in the details. While much has been made of record-breaking thermometer readings and “unprecedented” heat waves, the average global temperature has risen by just 1°F in the past hundred years. If this doesn’t seem like much, well, it isn’t and, moreover, it has been unevenly distributed: temperatures rose from 1920-1940, decreased for the next thirty years, increased again until the mid-1990s, and have been nearly flat since 1998.

This is not the result one would expect if human-generated greenhouse gas emissions, which have constantly increased, inevitably caused temperatures to rise. But such fluctuations—and even more dramatic ones—are not only commonplace, they are inevitable, given a dynamic feedback system like that which exists between the Earth and Sun. There is even one current theory that posits super-cycles, within which the average global temperature varies between 120°F and minus 50. It’s a wonder that life has endured at all.

How then should we address the coming 21st-century climate change (something will surely happen), and the proposition that it will primarily be driven by man who, many claim, is creating a massive greenhouse effect through the burning of fossil fuels?

There are many aspects to this but, to begin at the beginning, Al Gore and others, including most of the media, have been telling us there now exists a “consensus” viewpoint on man-made (anthropogenic) global warming (or AGW). For purposes of economy, let’s call them the alarmist faction. Furthermore, we’re told that the faction questioning the majority view—we’ll call them the skeptics—consists of only a tiny handful of shills for the oil industry.

Not so.

Take the famous “hockey stick,” for example. This is a graph that is routinely trotted out by the alarmists, and plays a large role in Gore’s film. It purports to show that global temperature was flat for most of the past millennium, before suddenly and ferociously spiking upward during the 20th century, thereby creating the business end of the hockey stick. I.e., AGW is out of control.

The graph was created by Dr. Michael Mann, then a climatologist at the University of Massachusetts, in a 1999 paper, and it was immediately and rather uncritically accepted.

One problem with Mann’s and others’ attempts to pin down global temps is that the thermometer wasn’t invented until the early 18th century. For data before that point, we have to rely on reconstructions based on inferences from historical records, and climate proxy indicators, such as tree rings (upon which Mann heavily relied), corals, lake sediments and ice core samples. And even there, most of the work has been done in, and on, the Northern Hemisphere, since that’s where most of the people are; we know little about what may have been going on to our south.

(Recent satellite tropospheric temperature data from NASA indicate that the Southern Hemisphere hasn’t heated up at all in the past 25 years; perhaps we should be discussing “north hemispheric” rather than “global” warming.)

Now, granted that research scientists’ methodologies have become increasingly sophisticated over the years, and high-speed computers have enabled the concatenation of huge amounts of data from many different sources. Many climatologists feel confident of their inferences about a given historical period. Nevertheless, it’s wise to keep in mind that there are disagreements, that all estimates are subject to considerable margins of error, and that anyone who purports to “know” for certain exactly how hot or cold it was in 1066 is being disingenuous, at best.

So what are we to make of Mann’s graph, in which actual thermometer-recorded temperatures for the past 150 years are casually grafted onto many more centuries of tree ring records? That’s a bit like gluing an apple to an orange and calling it a new type of fruit. It’s sloppy science.

Even if we completely accept the inferred temperatures scientists have given us—and even if we ignore the large margin of error Mann built into his original graph and which his disciples never bother to reproduce—there still emerges a very major problem with the hockey stick: the graph shouldn’t be flat between 1000 and 1900. During those nine hundred years there were some very substantial fluctuations. Most notable are the Medieval Warm Period that began abruptly around 1000 and peaked somewhat above today’s conditions around 1250 (thereby allowing the Vikings to establish farms in Greenland); and the Little Ice Age of the 15th-18th centuries, when it averaged a degree and a half colder.

The hockey stick simply ignores these periods, making them instead roughly flat, an alteration that geophysicist David Deming, of the University of Oklahoma, calls deliberate. He cites a colleague who, hoping to stir up alarmist sentiment over global warming, once wrote him that, “We have to get rid of the Medieval Warming Period.”

They did. If you leave it in, along with the Little Ice Age, then the graph no longer looks like a hockey stick, but more like a snake slithering along the ground. We are at one of the peaks of warmth, but there was another a thousand years ago, along with a really frigid trough four centuries back. With this perspective, as Dr. Deming writes, “late-twentieth-century temperatures are not anomalous or unusually warm.”

Dr. Deming’s opinion was borne out by a June 2006 publication from the National Academy of Sciences, titled Surface Temperature Reconstructions for the Last 2000 Years. In it, the NAS slammed Mann’s ignoring of the major hot and cold periods. Additionally, it said that “substantial uncertainties” surround the notion that the last half of the twentieth century was the warmest of the millennium and that, while the uncertainty increases the farther back in time one goes, “not all individual proxy records indicate that the recent warmth is unprecedented […] Even less confidence can be placed in the original conclusions by Mann et al. (1999) that the 1990’s are likely the warmest decade, and 1998 the warmest year, in at least a millennium …”

Commenting on the NAS study, the U.S. Senate’s leading skeptic, James Inhofe (R-OK), said in a September 2006 floor speech, “This report shows that the planet warmed for about 200 years prior to the industrial age, when we were coming out of the depths of the Little Ice Age […] Trying to prove man-made global warming by comparing the well-known fact that today’s temperatures are warmer than during the Little Ice Age is akin to comparing summer to winter to show a catastrophic temperature trend.”

Furthermore, the line at the end of the graph has suddenly gone flat. “There is a problem with global warming,” says paleoclimatologist Bob Carter of Australia’s James Cook University, “it stopped in 1998.” Despite all the excess CO2 our SUVs have been pumping into the atmosphere, Carter says, “official temperature records of the Climate Research Unit at the University of East Anglia in the UK [show that] the global average temperature did not increase between 1998-2005.”

All in all, that is one broken hockey stick.

But isn’t there still a “consensus” about global warming? Didn’t most of the world’s nations agree on that at Kyoto?

Well, consider a letter written to Canadian Prime Minister Stephen Harper in April of 2006, in an effort to get the government there to review actual climate change evidence before implementing provisions of the Kyoto Protocol.

The letter leads off by saying: “As accredited experts in climate and related scientific disciplines, we are writing to propose that balanced, comprehensive public-consultation sessions be held so as to examine the scientific foundation of the federal government’s climate-change plans […]

“Observational evidence,” it continues, “does not support today’s computer climate models [...] While the confident pronouncements of scientifically unqualified environmental groups may provide for sensational headlines, they are no basis for mature policy. The study of global climate change is [...] an ‘emerging science,’ one that is perhaps the most complex ever tackled. It may be many years yet before we properly understand the Earth’s climate system. Nevertheless, significant advances have been made since the protocol was created, many of which are taking us away from a concern about increasing greenhouse gases. If, back in the mid-1990s, we knew what we know today about climate, Kyoto would almost certainly not exist, because we would have concluded that it was not necessary […]

“When the public comes to understand that there is no ‘consensus’ among climate scientists about the relative importance of the various causes of global climate change, the government will be in a far better position to develop plans that reflect reality…”

After all, the authors say in conclusion, “It was only 30 years ago that many of today’s global-warming alarmists were telling us that the world was in the midst of a global-cooling catastrophe. But the science continued to evolve, and still does, even though so many choose to ignore it when it does not fit with predetermined political agendas.”

Who signed this letter? 61 of the world’s most prominent experts in the fields of Earth science, climatology, meteorology, geophysics, math and economics. Without them, the “consensus” is thin indeed.

Another consensus-buster came in the form of a reexamination of a study by UCSD social scientist Naomi Oreskes, published in Science, claiming that a review of abstracts of scientific papers on climate showed a 100% agreement that global warming is not the result of natural variations. Oreskes’ study was featured in An Inconvenient Truth.

Unfortunately for Oreskes and Gore, Dr. Benny Peiser, a British social scientist, took a close look at the study and found that Oreskes had referenced only 928 out of nearly 12,000 available papers on the subject. Even among those 928, Peiser found that only 2% wholly endorsed the view that human activity is driving global warming, and several of the studies actually opposed that conclusion.

Another striking image that many will remember from An Inconvenient Truth is of huge chunks of glacial ice breaking off from Antarctica and floating away, presented as “evidence” that the polar continent is warming.

Actually, no. This is what glaciers do when they’re growing. “The breaking glacial wall is a normally occurring phenomenon which is due to the normal advance of a glacier,” says Dr. Boris Winterhalter, a professor of marine geology at the University of Helsinki. “In Antarctica, the temperature is low enough to prohibit melting of the ice front, so if the ice is grounded, it has to break off in beautiful ice cascades.”

Some sections of Antarctica are warming, true enough. But others are cooling, with variations “probably because of a small change in the position of the low pressure systems,” says Dr. Wibjörn Karlén, a professor emeritus of geology at Stockholm University. Overall, Karlén says, the “mass balance” of Antarctica is positive—more ice is building up than melting off.

That’s what’s happening at the bottom of the world. What about at the top? Well, the Arctic was warmer in the 1930s than it is now. It cooled significantly in the ’60s. It warmed until the early ’80s, then cooled again through the mid-’90s. After a sudden 30% drop in ice thickness in the Canadian Arctic between 1996-1998, it has been rebuilding and is now near “normal” levels, whatever that means.

A 2003 paper by Igor Polyakov of the University of Alaska found no overall Arctic temperature rise since 1940. In fact, “For several published records, it is a decrease for the last 50 years,” Karlén says.

Similarly, scare stories about the melting of Greenland’s glaciers and the resulting rise of sea levels are premature. In October 2005, a study of Greenland ice was published by researchers from Bergen University’s Nansen Environmental and Remote Sensing Center (NERSC). The researchers analyzed “a continuous satellite-altimeter height record of Greenland Ice Sheet […] elevation changes over an 11-year period, 1992-2003.”

The NERSC team found that “below 1500 meters, the elevation-change rate is minus 2.0 ± 0.9 cm/year, in qualitative agreement with reported thinning in the ice-sheet margins” (i.e., the alarmists are correct that glaciers are melting along the coast). However, “an increase of 6.4 ± 0.2 cm/year is found in the vast interior areas above 1500 meters.” Averaged over the bulk of the ice sheet, the net result is a mean increase of about 5.4 cm/year. In plain terms, the Greenland ice is expanding, not contracting.

Alpine glaciers? Says Richard Lindzen, professor of atmospheric science at MIT, “Alpine glaciers have been retreating since the early 19th century [i.e. before the Industrial Revolution], and were advancing for several centuries before that. Since about 1970, many of the glaciers have stopped retreating and some are now advancing again. And, frankly, we don’t know why.”

There has also been steadily accumulating, supporting evidence that temperatures today bear about the same relationship to the millennial mean as did those in the Medieval Warm Period, to the upside, and the Little Ice Age, to the downside.

Researchers using proxies other than tree rings have fashioned a climate picture that is remarkably coherent, no matter where on the globe they look. To take one example, in 1996 Lloyd Keigwin, Senior Scientist of Geology and Geophysics at the Woods Hole Oceanographic Institution, published a 3,000-year reconstruction of sea temperatures in the Sargasso Sea, using radiocarbon dating correlated with marine organism populations found in seabed sediments.

Keigwin’s data clearly delineate the Medieval Warm Period (sea temps better than two degrees above the mean) and the Little Ice Age (more than two degrees below it), as well as spikes as high as four degrees above the mean in the first millennium B.C. Today, the Sargasso is right at the mean.

Other proxy studies have involved the study of coral off of Puerto Rico; of Kenyan and Taiwanese lake bed sediments; of oxygen-18 isotopes from ice cores in the Peruvian Andes and from South African stalagmites; and much more. In all of these studies, our era stands near the mid-point of temperature extremes between the Little Ice Age and the Medieval Warm Period.

Yet alarmists continue to proclaim that AGW is out of control.

One of the smoking guns they use is a 1996 report from the UN’s Intergovernmental Panel on Climate Change (IPCC). The IPCC’s website explains that it “does not carry out research nor does it monitor climate related data or other relevant parameters. It bases its assessment mainly on peer reviewed and published scientific/technical literature.” The panel is composed of representatives appointed by governments and organizations. Participation of delegates with appropriate expertise is “encouraged.”

In ’96 these experts concluded that, “The balance of evidence suggests a discernible human influence on global climate,” and set the basis for Kyoto.

However, Dr. Dick Morgan, a climatology researcher at England’s Exeter University, notes that the globe is anything but uniform. Along with the warming parts, he says, there are massive areas that are cooling, including the NW Atlantic, North and South Pacific Ocean, the Amazon valley, north coast of South America and the Caribbean, the eastern Mediterranean, Black Sea, Caucasus and Red Sea, New Zealand, and the Ganges Valley in India.

Furthermore, Morgan questions the IPCC’s methodology. “Had the IPCC used the standard parameter for climate change (the 30-year average) and used an equal area projection, instead of the Mercator (which doubled the area of warming in Alaska, Siberia and the Antarctic Ocean), warming and cooling would have been almost in balance.”

And while we’re on the subject of methodology, one further note. The alarmists’ dire scenarios are based on computer models of the planet’s future, and models are always iffy, to say the least. They depend on what data is put in and how that data is massaged. With regard to weather and climate, they’re often way wrong. Remember the ultra-violent hurricane season computers warned about for the summer of 2006? Didn’t happen. But no doubt, after the savage storms of 2005, big hurricane seasons will continue to be predicted. Any of us can do that, with or without a super-computer and, eventually, the laws of probability will make sages of us.

Are the alarmists right about anything, then? Yes. For example, sea levels are rising. But then, they have been since the peak of the last Ice Age, 18,000 years ago. They’ve risen some 400 feet in the interim. “In recent millennia,” writes S. Fred Singer, an atmospheric physicist and professor emeritus of environmental science at the University of Virginia, “the rate has been 18 cm (7 inches) per century—and there is good argument for this rate to continue until the next ice age. Tidal gauges show no acceleration during the 20th century but only a steady rise [...] Evidently, the rise expected from melting glaciers and a warmer, expanding ocean is largely offset by loss of water from increased ocean evaporation and more ice accumulation on the Antarctic continent.”

It is also true that atmospheric carbon dioxide levels are increasing, from about 280 parts per million in the 19th century to some 387 ppm today, and that humans are primarily responsible for this. That’s about a 38% jump in 100+ years, something the alarmists find, well, alarming.

It’s not, Professor Lindzen maintains, writing that, “carbon dioxide is an infrared absorber (i.e. a greenhouse gas—albeit a minor one), and its increase should theoretically contribute to warming. Indeed, if all else were kept equal, the increase in carbon dioxide should have led to somewhat more warming than has been observed, assuming that the small observed increase was in fact due to increasing carbon dioxide rather than a natural fluctuation in the climate system.”

Not to mention that the relationship between CO2 levels and temperature is far from clear. There is an intricate interplay between release of the gas by humans and natural sources, and uptake by the ocean, plants and soil. Given the dynamism of the process, it is a bit surprising that atmospheric carbon dioxide has remained as stable as it has for the past millennium, before spiking up, in hockey stick fashion, only recently.

Will the upward curve continue indefinitely, as alarmists fear? Or will some other element of the system change, bringing CO2 levels down again? No one knows. What is known is that there have been more significant surface temperature changes during the past thousand years than we are experiencing today, and that CO2 levels were not a factor.

What was the deciding factor, then? Again, no one can say, except that it was probably a combination of ingredients.

The most important of these is the amount of solar radiation that is received on the Earth’s surface. Everyone agrees that greenhouse gases like carbon dioxide (and, much more importantly, water vapor) can serve to trap the sun’s heat and raise surface temperatures. But it’s a feedback system, depending not only on greenhouse gas levels, but on how much heat there is to trap, and that varies for a number of reasons.

For one, the sun itself goes through periods of greater and lesser radiation, with the presence or absence of sunspots being a good indicator. Sunspots are cyclical. So is the variation in the shape of the Earth’s orbit; when it’s at its most elliptical, it receives about 20% less radiation than when it’s at its least elliptical, a state it’s now approaching. Also of influence are the regular changes in the tilt of the Earth’s axis and the effects of planetary wobbling on that axis.

Finally, there’s one other question that’s seldom posed: what are the benefits of global warming? Now, we’re not talking about it becoming so hot that the Earth becomes a skillet and we the bacon. But no model foresees that.

Some will be negatively impacted, but that’s true of any change, man-made or natural. On the other hand, warmer temperatures mean later frosts and longer growing seasons. Crops could be raised where they cannot today. Ocean evaporation would rise, increasing the global supply of fresh water. Farmers could repopulate Greenland.

To us, that doesn’t sound bad. What sounds much worse is that we may have the enormous good fortune to inhabit one of the most benign climatic eras ever, and that ice ages will continue to alternate with interglacials like the present. The giant glaciers tend to grow and recede on a 12,000-year cycle, which means they’re about due to return again. When and if they do, they’ll override our land, flatten our proud skyscrapers, and relentlessly drive humanity into ever more densely populated southern latitudes. Those already living there are not likely to open welcoming arms.

It isn’t a pretty picture. Trapping a bit more of the sun’s heat looks like a very viable alternative.

To sum up, in the spirit of full disclosure we cheerfully confess that we are not physicists, or climatologists, or any other kind of authority on the subject of global warming. We don’t have a clue what’s up for 2007, much less the coming century—best guess based on the evidence we’ve reviewed: continued moderate warming, due in some part to human activity—and we rather suspect no one else does, either. All we did was look into the debate, and we hope that we’ve brought to our readers’ attention the fact that there is a debate, that the absolute “consensus” you hear about is a myth.

The consensus tale has been placed in the hands of some very potent myth makers, including prominent scientists, politicians, and most members of the media. We don’t believe that all of them have been deliberately lying to us, although some have.

We do believe that the debate should be taking place out in the open, with both sides presenting evidence, rather than engaging in name calling. We also believe the mass media should do a better job of framing the debate, but we doubt that they will. Fear sells, and the absence of fear is a non-starter. It’s just that simple. The media has glommed onto the alarmists’ point of view, because it is apocalyptic and generates better headlines. The skeptics get short shrift.

Alarmist and skeptic alike, though, agree on one thing: The sun will eventually burn itself out, leaving Earth as a cold, lifeless rock. Now that’s global climate change.

Great post! A bit long, perhaps a URL and intro/conclusion. Ah well, here are some more questions, and kudos to CA for having a paper that bothers to present another side. The article this is linked to is interesting, but contains the change of mind of one scientist. More to the point for this forum, check out the 'series' found at the link:

The real deal?
Against the grain: Some scientists deny global warming exists

ice

Astrophysicist Nir Shariv, one of Israel's top young scientists, describes the logic that led him -- and most everyone else -- to conclude that SUVs, coal plants and other things man-made cause global warming.

Step One Scientists for decades have postulated that increases in carbon dioxide and other gases could lead to a greenhouse effect.

Step Two As if on cue, the temperature rose over the course of the 20th century while greenhouse gases proliferated due to human activities.

Step Three No other mechanism explains the warming. Without another candidate, greenhouses gases necessarily became the cause.

The series

Statistics needed -- The Deniers Part I
Warming is real -- and has benefits -- The Deniers Part II
The hurricane expert who stood up to UN junk science -- The Deniers Part III
Polar scientists on thin ice -- The Deniers Part IV
The original denier: into the cold -- The Deniers Part V
The sun moves climate change -- The Deniers Part VI
Will the sun cool us? -- The Deniers Part VII
The limits of predictability -- The Deniers Part VIII
Look to Mars for the truth on global warming -- The Deniers Part IX
Limited role for C02 -- the Deniers Part X​

Dr. Shariv, a prolific researcher who has made a name for himself assessing the movements of two-billion-year-old meteorites, no longer accepts this logic, or subscribes to these views. He has recanted: "Like many others, I was personally sure that CO2 is the bad culprit in the story of global warming. But after carefully digging into the evidence, I realized that things are far more complicated than the story sold to us by many climate scientists or the stories regurgitated by the media.

"In fact, there is much more than meets the eye."

Dr. Shariv's digging led him to the surprising discovery that there is no concrete evidence -- only speculation -- that man-made greenhouse gases cause global warming. Even research from the Intergovernmental Panel on Climate Change-- the United Nations agency that heads the worldwide effort to combat global warming -- is bereft of anything here inspiring confidence. In fact, according to the IPCC's own findings, man's role is so uncertain that there is a strong possibility that we have been cooling, not warming, the Earth. Unfortunately, our tools are too crude to reveal what man's effect has been in the past, let alone predict how much warming or cooling we might cause in the future...

Climate of Opinion
The latest U.N. report shows the "warming" debate is far from settled.

Monday, February 5, 2007 12:01 a.m. EST

Last week's headlines about the United Nation's latest report on global warming were typically breathless, predicting doom and human damnation like the most fervent religious evangelical. Yet the real news in the fourth assessment from the Intergovernmental Panel on Climate Change (IPCC) may be how far it is backpedaling on some key issues. Beware claims that the science of global warming is settled.

The document that caused such a stir was only a short policy report, a summary of the full scientific report due in May. Written mainly by policymakers (not scientists) who have a stake in the issue, the summary was long on dire predictions. The press reported the bullet points, noting that this latest summary pronounced with more than "90% confidence" that humans have been the main drivers of warming since the 1950s, and that higher temperatures and rising sea levels would result.

More pertinent is the underlying scientific report. And according to people who have seen that draft, it contains startling revisions of previous U.N. predictions. For example, the Center for Science and Public Policy has just released an illuminating analysis written by Lord Christopher Monckton, a one-time adviser to Margaret Thatcher who has become a voice of sanity on global warming.

Take rising sea levels. In its 2001 report, the U.N.'s best high-end estimate of the rise in sea levels by 2100 was three feet. Lord Monckton notes that the upcoming report's high-end best estimate is 17 inches, or half the previous prediction. Similarly, the new report shows that the 2001 assessment had overestimated the human influence on climate change since the Industrial Revolution by at least one-third.

Such reversals (and there are more) are remarkable, given that the IPCC's previous reports, in 1990, 1995 and 2001, have been steadily more urgent in their scientific claims and political tone. It's worth noting that many of the policymakers who tinker with the IPCC reports work for governments that have promoted climate fears as a way of justifying carbon-restriction policies. More skeptical scientists are routinely vetoed from contributing to the panel's work. The Pasteur Institute's Paul Reiter, a malaria expert who thinks global warming would have little impact on the spread of that disease, is one example....

Planet Gore

By The Editors



The U.N.’s Intergovernmental Panel on Climate Change (IPCC) has released a summary of its latest report. This has had the intended effect: generating fresh gloom-and-doom headlines about global warming. “A grim and powerful assessment of the future of the planet,” said the New York Times, a representative example. The chairman of the IPCC, Rajendra Pachauri, said, “I hope this report will shock people.”

The shock, however, is that the latest summary contains very little that was not in the IPCC’s last report, in 2001. Moreover, what is new represents a pullback from the gloomier claims of 2001. Notwithstanding the authors’ bold assertion of 95-percent confidence that human activity influences global warming, it appears from this short summary of the full 1,400-page report — which, inexplicably, the IPCC won’t release until May — that there has been only slight progress over the past five years in refining our climate models and resolving key uncertainties acknowledged in the last report...

...Gone from the latest summary is the infamous “hockey stick” of the 2001 report. This was a graphic purporting to show that the planet is warmer today than at any time in the last thousand years, a demonstration which required erasing the inconvenient medieval warm period and the little ice age. The new IPCC report has also reduced its estimate of the human influence on warming by one-third (though this change was not flagged for the media, so few if any news accounts took notice of it). That reduction is one reason the IPCC narrowed the range of predicted future warming, and lowered the new midpoint — i.e., the most likely prediction of temperature increase — by a half degree, from 3.5 degrees Celsius in 2001 to 3 degrees in this report. The new assessment also cuts in half the range of predicted sea-level rise over the next century. Now the maximum prediction is about 17 inches, as compared with the 20 to 30 feet Al Gore dramatizes in his horror film. (Which truths are inconvenient now?) There are murmurs from the green warriors that the new report is a disappointment, and no wonder.

Keep in mind that this summary covers only one of the three IPCC working groups that will report their findings later this year. Good news for insomniacs: The three complete reports, covering science, impacts, and mitigation, will run to nearly 5,000 pages. It’s troubling that, in what seems a clear attempt to spin the media, the IPCC has released only one summary in advance of the complete reports.

Climate change is real — the world is warming modestly, and this fact should be taken seriously. But the continuing panic of Gore & Co. in the face of growing evidence that previous predictions were exaggerated and politicized should bolster the position of those who advocate sensible climate policy. Such policy would emphasize development of new energy technologies, and eschew the starvation diet of the Kyoto Protocol.

I wish there really was global warming.



Anyone who has been outdoors for any length of time from the Dakotas to the Northeast U.S. probably does not have to be reminded as to how cold it feels outside. Just in case you were wondering what it feels like up north, or perhaps you were curious why your bare hand stuck to the trash can lid, here goes. Shown below are what the lowest actual temperatures have been the past few days and what the lowest AccuWeather RealFeel® Temperature was so far:

International Falls, MN. - Lowest Temperature minus 32° RealFeel minus 47°.
Fargo, ND. - Lowest Temperature minus 24° RealFeel minus 44°.
Sioux Falls, SD. - Lowest Temperature minus 13° RealFeel minus 36°.
Des Moines, IA. - Lowest Temperature minus 9° RealFeel minus 35°.
Chicago, IL. - Lowest Temperature minus 9° RealFeel minus 35°.
Detroit, MI. - Lowest Temperature minus 4° RealFeel minus 25°.
Indianapolis, IN. - Lowest Temperature minus 5° RealFeel minus 24°.

For most places in the Midwest, the core of the cold air is sliding to your east and you probably already have experienced the lowest temperatures of this particular outbreak. However, for those of you in the northern and central Appalachians, as well as along the coastal Northeast, the coldest morning so far is on the way Tuesday.



For skiing interests in the Northeast, this pattern has been long awaited, allowing for ample snowmaking and fresh powder. Be sure to dress appropriately if you plan on taking to the slopes the
next few days and travel wisely in areas being clobbered by lake-effect in the snowbelts of western and upstate New York and northwestern Pennsylvania.

Global Warming is not due to human contribution of Carbon Dioxide
Global Warming: The Cold, Hard Facts?
By Timothy Ball

Monday, February 5, 2007

Global Warming, as we think we know it, doesn't exist. And I am not the only one trying to make people open up their eyes and see the truth. But few listen, despite the fact that I was the first Canadian Ph.D. in Climatology and I have an extensive background in climatology, especially the reconstruction of past climates and the impact of climate change on human history and the human condition. Few listen, even though I have a Ph.D, (Doctor of Science) from the University of London, England and was a climatology professor at the University of Winnipeg. For some reason (actually for many), the World is not listening. Here is why.


What would happen if tomorrow we were told that, after all, the Earth is flat? It would probably be the most important piece of news in the media and would generate a lot of debate. So why is it that when scientists who have studied the Global Warming phenomenon for years say that humans are not the cause nobody listens? Why does no one acknowledge that the Emperor has no clothes on?

Believe it or not, Global Warming is not due to human contribution of Carbon Dioxide (CO2). This in fact is the greatest deception in the history of science. We are wasting time, energy and trillions of dollars while creating unnecessary fear and consternation over an issue with no scientific justification. For example, Environment Canada brags about spending $3.7 billion in the last five years dealing with climate change almost all on propaganda trying to defend an indefensible scientific position while at the same time closing weather stations and failing to meet legislated pollution targets.

No sensible person seeks conflict, especially with governments, but if we don't pursue the truth, we are lost as individuals and as a society. That is why I insist on saying that there is no evidence that we are, or could ever cause global climate change. And, recently, Yuri A. Izrael, Vice President of the United Nations sponsored Intergovernmental Panel on Climate Change (IPCC) confirmed this statement. So how has the world come to believe that something is wrong?

Maybe for the same reason we believed, 30 years ago, that global cooling was the biggest threat: a matter of faith. "It is a cold fact: the Global Cooling presents humankind with the most important social, political, and adaptive challenge we have had to deal with for ten thousand years. Your stake in the decisions we make concerning it is of ultimate importance; the survival of ourselves, our children, our species," wrote Lowell Ponte in 1976.

I was as opposed to the threats of impending doom global cooling engendered as I am to the threats made about Global Warming. Let me stress I am not denying the phenomenon has occurred. The world has warmed since 1680, the nadir of a cool period called the Little Ice Age (LIA) that has generally continued to the present. These climate changes are well within natural variability and explained quite easily by changes in the sun. But there is nothing unusual going on.

Since I obtained my doctorate in climatology from the University of London, Queen Mary College, England my career has spanned two climate cycles. Temperatures declined from 1940 to 1980 and in the early 1970's global cooling became the consensus. This proves that consensus is not a scientific fact. By the 1990's temperatures appeared to have reversed and Global Warming became the consensus. It appears I'll witness another cycle before retiring, as the major mechanisms and the global temperature trends now indicate a cooling.

No doubt passive acceptance yields less stress, fewer personal attacks and makes career progress easier. What I have experienced in my personal life during the last years makes me understand why most people choose not to speak out; job security and fear of reprisals. Even in University, where free speech and challenge to prevailing wisdoms are supposedly encouraged, academics remain silent.

I once received a three page letter that my lawyer defined as libellous, from an academic colleague, saying I had no right to say what I was saying, especially in public lectures. Sadly, my experience is that universities are the most dogmatic and oppressive places in our society. This becomes progressively worse as they receive more and more funding from governments that demand a particular viewpoint.

In another instance, I was accused by Canadian environmentalist David Suzuki of being paid by oil companies. That is a lie. Apparently he thinks if the fossil fuel companies pay you have an agenda. So if Greenpeace, Sierra Club or governments pay there is no agenda and only truth and enlightenment?

Personal attacks are difficult and shouldn't occur in a debate in a civilized society. I can only consider them from what they imply. They usually indicate a person or group is losing the debate. In this case, they also indicate how political the entire Global Warming debate has become. Both underline the lack of or even contradictory nature of the evidence.

I am not alone in this journey against the prevalent myth. Several well-known names have also raised their voices. Michael Crichton, the scientist, writer and filmmaker is one of them. In his latest book, "State of Fear" he takes time to explain, often in surprising detail, the flawed science behind Global Warming and other imagined environmental crises.

Another cry in the wildenerness is Richard Lindzen's. He is an atmospheric physicist and a professor of meteorology at MIT, renowned for his research in dynamic meteorology - especially atmospheric waves. He is also a member of the National Academy of Sciences and has held positions at the University of Chicago, Harvard University and MIT. Linzen frequently speaks out against the notion that significant Global Warming is caused by humans. Yet nobody seems to listen.

I think it may be because most people don't understand the scientific method which Thomas Kuhn so skilfully and briefly set out in his book "The Structure of Scientific Revolutions." A scientist makes certain assumptions and then produces a theory which is only as valid as the assumptions. The theory of Global Warming assumes that CO2 is an atmospheric greenhouse gas and as it increases temperatures rise. It was then theorized that since humans were producing more CO2 than before, the temperature would inevitably rise. The theory was accepted before testing had started, and effectively became a law.

As Lindzen said many years ago: "the consensus was reached before the research had even begun." Now, any scientist who dares to question the prevailing wisdom is marginalized and called a sceptic, when in fact they are simply being good scientists. This has reached frightening levels with these scientists now being called climate change denier with all the holocaust connotations of that word. The normal scientific method is effectively being thwarted.

Meanwhile, politicians are being listened to, even though most of them have no knowledge or understanding of science, especially the science of climate and climate change. Hence, they are in no position to question a policy on climate change when it threatens the entire planet. Moreover, using fear and creating hysteria makes it very difficult to make calm rational decisions about issues needing attention.

Until you have challenged the prevailing wisdom you have no idea how nasty people can be. Until you have re-examined any issue in an attempt to find out all the information, you cannot know how much misinformation exists in the supposed age of information.

I was greatly influenced several years ago by Aaron Wildavsky's book "Yes, but is it true?" The author taught political science at a New York University and realized how science was being influenced by and apparently misused by politics. He gave his graduate students an assignment to pursue the science behind a policy generated by a highly publicised environmental concern. To his and their surprise they found there was little scientific evidence, consensus and justification for the policy. You only realize the extent to which Wildavsky's findings occur when you ask the question he posed. Wildavsky's students did it in the safety of academia and with the excuse that it was an assignment. I have learned it is a difficult question to ask in the real world, however I firmly believe it is the most important question to ask if we are to advance in the right direction.

The central question, it would seem, has been answered. Are we in a period of global warming?
Yes, sort of.
As always, the devil is in the details. While much has been made of record-breaking thermometer readings and “unprecedented” heat waves, the average global temperature has risen by just 1°F in the past hundred years. If this doesn’t seem like much, well, it isn’t and, moreover, it has been unevenly distributed: temperatures rose from 1920-1940, decreased for the next thirty years, increased again until the mid-1990s, and have been nearly flat since 1998.

This is not the result one would expect if human-generated greenhouse gas emissions, which have constantly increased, inevitably caused temperatures to rise.
This isn't true. It would only be a result we wouldn't expect if human-generated greenhouse gas emissions were the only forcing on global temperature, but they are not. Global warmings also include solar forcings, aerosol forcings and volcanic forcings among other factors.

It is true that 20th century temperature trend cannot be explained by greenhouse gas trends alone, but conversely models are unable to explain the last few decades of warming without including the greenhouse gas forcings.

There's a lot more at error in the article. Not the worst article I've seen, but certaintly not a good one.

The document that caused such a stir was only a short policy report, a summary of the full scientific report due in May. Written mainly by policymakers (not scientists) who have a stake in the issue[/quote]

Actually that's not true. The people writing the summary are scientists. The confusion is because each participating country is represented by a scientist. The other conf

Take rising sea levels. In its 2001 report, the U.N.'s best high-end estimate of the rise in sea levels by 2100 was three feet. Lord Monckton notes that the upcoming report's high-end best estimate is 17 inches, or half the previous prediction.
This is because the IPCC have left out the contribution of ice sheets, which the 2001 report did contain. They left it out because of increased uncertainty in how they will react in future, as discussed here:

http://www.realclimate.org/index.ph...ea-level-rise-model-failure-is-the-key-issue/

The limitations of ice sheet models were revealed starkly by the collapse of the northern sections of the Larson B ice shelf in 1998 and 2002. Glaciers bounded by the landward edge of the ice shelf accelerated toward the sea while glaciers bounded by the more southerly section of the ice shelf, which remained intact, didn’t. Apparently, backpressure on glaciers from the abutting ice shelf provides a significant portion of the restraining forces keeping land-based ice in place, at least in some instances. The recent behavior of glaciers farther south in West Antarctica, and in Greenland, points to a similar dynamical response to ice-shelf fragmentation.
Given that the models could not reproduce these events, and these events contributed significantly to the contribution of ice sheets, they removed this factor from the forecast, which means that sea level forcast is lower in the new report than in the last.

Similarly, the new report shows that the 2001 assessment had overestimated the human influence on climate change since the Industrial Revolution by at least one-third.
I don't believe this is true.

Is it because you haven't published anything on climate for about 15 years?

Nah...it's probably because there's a conspiracy of course...that's why they won't listen man

Maybe for the same reason we believed, 30 years ago, that global cooling was the biggest threat
That wasn't the position of the science at the time.

These climate changes are well within natural variability and explained quite easily by changes in the sun. But there is nothing unusual going on.
The science disagrees. No scientist has been able to explain recent warming in the past few decades as solar. The most anyone has come to is about 30% solar.
Temperatures declined from 1940 to 1980 and in the early 1970's global cooling became the consensus.
No it didn't. Here's some pages from National Geographic in 1976 (which isn't a good science source but it does demonstrate a point in this case):
http://www.wmconnolley.org.uk/sci/iceage/DSCN1557-nat-geog-1976_1200x900.JPG

Notice the future forecast on the graph is says both "Warming?" and "Cooling?" Ie uncertainty. Scientists at the time realised human activity could result in warming or could result in cooling, and didn't know which.

The only way people claim there was a consensus global cooling back in the early 70s is to cherrypick quotes from the time about the possible cooling forecast, and not mention the possible warming forecast at all, therefore implying that cooling was being predicted.

In fact the page which that National Geographic photo comes (http://www.wmconnolley.org.uk/sci/iceage/nat-geog-1976-11.html has some great quotes illustrating this.

1. The New American says (V20 #21, Oct 2004) "National Geographic now claims that the Earth is heating up at an alarming rate. But in 1976 the magazine worried that falling temperatures could lead to another ice age."
See what they did there? It's not a lie, but it's highly misleading.

And another:

2. Mike Oliver, at "energytruth.com" says In November, 1976 the National Geographic carried a warning that "the oceans would eventually freeze" and "snow would advance to the equator"

I wish there really was global warming.



Anyone who has been outdoors for any length of time from the Dakotas to the Northeast U.S. probably does not have to be reminded as to how cold it feels outside. Just in case you were wondering what it feels like up north, or perhaps you were curious why your bare hand stuck to the trash can lid, here goes. Shown below are what the lowest actual temperatures have been the past few days and what the lowest AccuWeather RealFeel® Temperature was so far:

International Falls, MN. - Lowest Temperature minus 32° RealFeel minus 47°.
Fargo, ND. - Lowest Temperature minus 24° RealFeel minus 44°.
Sioux Falls, SD. - Lowest Temperature minus 13° RealFeel minus 36°.
Des Moines, IA. - Lowest Temperature minus 9° RealFeel minus 35°.
Chicago, IL. - Lowest Temperature minus 9° RealFeel minus 35°.
Detroit, MI. - Lowest Temperature minus 4° RealFeel minus 25°.
Indianapolis, IN. - Lowest Temperature minus 5° RealFeel minus 24°.
St. Louis, MO. - Lowest Temperature 5° RealFeel minus 9°.
Columbus, OH. - Lowest Temperature 0° RealFeel minus 21°.
Nashville, TN. - Lowest Temperature 16° RealFeel 6°.
Elkins, WV. - Lowest Temperature minus 3° RealFeel minus 24°.
Washington, DC. - Lowest Temperature 14° RealFeel minus 8°.
Philadelphia, PA. - Lowest Temperature 10° RealFeel minus 16°.
New York, NY. - Lowest Temperature 8° RealFeel minus 10°.
Boston, MA. - Lowest Temperature 10° RealFeel minus 15°.

A good first place to start, private jets:

http://blogs.knoxnews.com/knx/silence/archives/2007/02/fly_the_crowded_1.shtml

Wow. Check out the corporate jets leaving Miami after the Superbowl.



And friendly skies are going to get more crowded:

Third, the impact on the system of the much-anticipated introduction of great numbers of very light jets (VLJs) must be evaluated and dealt with. It is this last matter – the airspace implications of this new category of system user – that is the subject of our statement.

The left wants you fired from your job if you do not buy in to the junk science of global warming



Global warming debate spurs Ore. title tiff

06:09 PM PST on Tuesday, February 6, 2007

By VINCE PATTON, kgw.com

In the face of evidence agreed upon by hundreds of climate scientists, George Taylor holds firm. He does not believe human activities are the main cause of global climate change.


Taylor also holds a unique title: State Climatologist.

Hundreds of scientists last Friday issued the strongest warning yet on global warming saying humans are "very likely" the cause.


“Most of the climate changes we have seen up until now have been a result of natural variations,” Taylor asserts.


Taylor has held the title of "state climatologist" since 1991 when the legislature created a state climate office at OSU The university created the job title, not the state

His opinions conflict not only with many other scientists, but with the state of Oregon's policies.


So the governor wants to take that title from Taylor and make it a position that he would appoint.


In an exclusive interview with KGW-TV, Governor Ted Kulongoski confirmed he wants to take that title from Taylor. The governor said Taylor's contradictions interfere with the state's stated goals to reduce greenhouse gases, the accepted cause of global warming in the eyes of a vast majority of scientists.


“He is Oregon State University's climatologist. He is not the state of Oregon's climatologist,” Kulongoski said.


Taylor declined to comment on the proposal other than to say he was a "bit shocked" by the news. He recently engaged in a debate at O.M.S.I. and repeated his doubts about accepted science.


In an interview he told KGW, "There are a lot of people saying the bulk of the warming of the last 50 years is due to human activities and I don't believe that's true." He believes natural cycles explain most of the changes the earth has seen.


A bill will be introduced in Salem soon on the matter.


Sen. Brad Avakian, (D) Washington County, is sponsoring the bill. He said global warming is so important to state policy it's important to have a climatologist as a consultant to the governor. He denied this is targeted personally at Taylor. "Absolutely not," Avakian said, "I've never met Mr. Taylor and if he's got opinions I hope he comes to the hearing and testifies."


Kulongoski said the state needs a consistent message on reducing greenhouse gases to combat climate change.


The Governor says, "I just think there has to be somebody that says, 'this is the state position on this.'"

Was Al Gore on one of the private jets?



Gore isn't quite as green as he's led the world to believe

Al Gore has spoken: The world must embrace a "carbon-neutral lifestyle." To do otherwise, he says, will result in a cataclysmic catastrophe. "Humanity is sitting on a ticking time bomb," warns the website for his film, An Inconvenient Truth. "We have just 10 years to avert a major catastrophe that could send our entire planet into a tailspin."

Graciously, Gore tells consumers how to change their lives to curb their carbon-gobbling ways: Switch to compact fluorescent light bulbs, use a clothesline, drive a hybrid, use renewable energy, dramatically cut back on consumption. Better still, responsible global citizens can follow Gore's example, because, as he readily points out in his speeches, he lives a "carbon-neutral lifestyle." But if Al Gore is the world's role model for ecology, the planet is doomed.

For someone who says the sky is falling, he does very little. He says he recycles and drives a hybrid. And he claims he uses renewable energy credits to offset the pollution he produces when using a private jet to promote his film. (In reality, Paramount Classics, the film's distributor, pays this.)

Public records reveal that as Gore lectures Americans on excessive consumption, he and his wife Tipper live in two properties: a 10,000-square-foot, 20-room, eight-bathroom home in Nashville, and a 4,000-square-foot home in Arlington, Va. (He also has a third home in Carthage, Tenn.) For someone rallying the planet to pursue a path of extreme personal sacrifice, Gore requires little from himself.

Then there is the troubling matter of his energy use. In the Washington, D.C., area, utility companies offer wind energy as an alternative to traditional energy. In Nashville, similar programs exist. Utility customers must simply pay a few extra pennies per kilowatt hour, and they can continue living their carbon-neutral lifestyles knowing that they are supporting wind energy. Plenty of businesses and institutions have signed up. Even the Bush administration is using green energy for some federal office buildings, as are thousands of area residents.

But according to public records, there is no evidence that Gore has signed up to use green energy in either of his large residences. When contacted Wednesday, Gore's office confirmed as much but said the Gores were looking into making the switch at both homes. Talk about inconvenient truths.

Gore is not alone. Democratic National Committee Chairman Howard Dean has said, "Global warming is happening, and it threatens our very existence." The DNC website applauds the fact that Gore has "tried to move people to act." Yet, astoundingly, Gore's persuasive powers have failed to convince his own party: The DNC has not signed up to pay an additional two pennies a kilowatt hour to go green. For that matter, neither has the Republican National Committee.

Maybe our very existence isn't threatened.

Gore has held these apocalyptic views about the environment for some time. So why, then, didn't Gore dump his family's large stock holdings in Occidental (Oxy) Petroleum? As executor of his family's trust, over the years Gore has controlled hundreds of thousands of dollars in Oxy stock. Oxy has been mired in controversy over oil drilling in ecologically sensitive areas.

Living carbon-neutral apparently doesn't mean living oil-stock free. Nor does it necessarily mean giving up a mining royalty either.

Humanity might be "sitting on a ticking time bomb," but Gore's home in Carthage is sitting on a zinc mine. Gore receives $20,000 a year in royalties from Pasminco Zinc, which operates a zinc concession on his property. Tennessee has cited the company for adding large quantities of barium, iron and zinc to the nearby Caney Fork River.

The issue here is not simply Gore's hypocrisy; it's a question of credibility. If he genuinely believes the apocalyptic vision he has put forth and calls for radical changes in the way other people live, why hasn't he made any radical change in his life? Giving up the zinc mine or one of his homes is not asking much, given that he wants the rest of us to radically change our lives.

and what exactley is it you think you're doing?

None of this is about science anymore. It's about people with agendas who have things to gain by being 'right'. The only way we're gonna find out the truth about the future is when it happens.

At the very, very least we have to admit there is a lot of information available that attempts to support both sides of the argument.

I tend to take a big picture approach to most things and this issue is no different so I ask myself some big picutre questions:

1)Would someone like Al Gore, who is a big believer in one theory, really like to find out if he's wrong?

2)If not, why does he want to be right? Afterall, whether you believe the Gore theory or not you would think it is something everybody would like to be wrong about, but the way that side argues that doesn't seem to be the case. Instead all the energy seems to be focused on finding evidence that supports their case.

3)Concerning global climate in general, at this point in time, what is the whether "suppossed" to be like right now?

4)There also seems to be general consenus about the amount the temp has risen, which is roughly 1 degree F. I REPEAT 1 FRIGGIN DEGREE. Can somone tell me what the worry is a 1 degree increase?

100 inches of snow possible
From the Associated Press
February 8, 2007

Global warming? Tell that to the folks in upstate NY


CHARLESTON, W.VA. — West Virginia called snowplow drivers out of retirement Wednesday as snowstorms and arctic cold blamed for at least 16 deaths hung over much of the Midwest and East. Parts of upstate New York could get more than 100 inches of snow before the massive cold system breaks up Sunday or Monday, forecasters said.

As much as 9 inches of snow fell in West Virginia in the state's first major storm of the season, prompting schools statewide to either close or open late for a second day in a row. Schools were also shut down across much of Ohio and parts of New York.



In West Virginia, 21 retired snowplow drivers were called in to help crews struggling to clear roads.

But for some, the weather was ideal.

"It was the perfect storm," said Joe Stevens, spokesman for the West Virginia Ski Areas Assn. "Over 4 feet of snow has fallen since the middle of January, which has really turned the situation around for the resorts."

and what exactley is it you think you're doing?
I am just pointing out that many global warming skeptics have tried to downplay scientific support for global warming by claiming that there was equal scientific support for a global cooling theory 30 years ago.

Arguments are made such as
"just 30 years ago global cooling was the scientific consensus"
and
"Just 30 years ago global cooling was all the rage"

But the contrast between today and then demonstrates these arguments to be misleading.

Today you have every US scientific body which is related to climate having an official position of agreement with AGW theory. That includeds the AMS (American Meteorological Society), the NOAA (National Oceanic and Atmospheric Administration), the AGU (American Geophysical Union), the AAAS (American Association for the Advancement of Science) and the NAS (National Academy of Sciences).

Yet no scientific bodies had an official position of supporting a global cooling theory during the 70s, simply because no such theory did dominate climate science back then.

It's a false argument that is only kept going via the rumor and myth mills out there who want it to be true.

I don't think the skeptics are downplaying the fact that it is getting warmer. What they are pointing out is that in thirty years a different theory was reached and basically reminding us that this is constantly studied topic that is open to change again and again. Tommy Lee Jones put it best in MIB: "A thousand years ago everybody "knew" the earth was the center of the universe. Five hundred years ago, they "knew" it was flat. Fifteen minutes ago, you "knew" we humans were alone on it. Imagine what you'll "know" tomorrow."


Arguments are made such as
"just 30 years ago global cooling was the scientific consensus"
and
"Just 30 years ago global cooling was all the rage"

But the contrast between today and then demonstrates these arguments to be misleading.
It isn't misleading. Again it's simply pointing out that with knew knowledge comes new conclusions. To think that the currenlty held "conclusion" is the be all and end all one is silly.

Again the question is not whether the Earth is getting warmer. That is easily verifiable. The question is, is it natural? If not how much has man contributed to it? and is it enough to be worried about?

Right now only the extremists are talking. Another question is, is the alarmist attitude of Gore and his ilk the appropriate one at this point? I thought the portion of the earlier article about the omissions in the hockey stick graph were particularilly interesting. With those omissions added it would be very difficult to make the argument that this is a man made or that man is the major cause. So again i ask why do people want to prove the Global Warming is doomsday? I am perfectly willing to examine whatever evidence is out there. It is Gore and his ilk that seemingly won't

I don't think the skeptics are downplaying the fact that it is getting warmer. What they are pointing out is that in thirty years a different theory was reached
My entire point is that this isn't true. There was no different theory reached 30 years ago. There was no such theory 30 years ago analogous to global warming today.

It isn't misleading. Again it's simply pointing out that with knew knowledge comes new conclusions.
It is misleading because the claims are not true. The claims such as:
"just 30 years ago global cooling was the scientific consensus"
"Just 30 years ago global cooling was all the rage"
There was no such consensus or any such rage about global cooling 30 years ago.

The actual situation 30 years ago was that there was very little knowledge compared to today. Scientists could see human activity changing the composition of the atmosphere, but did not know what overall effect this would have on temperature. There was no widely held position on which direction temperature would go. It was only with more knowledge that they arrived to the position of global warming today.

To think that the currenlty held "conclusion" is the be all and end all one is silly.
But without the misleading claim of "global cooling" theory 30 years ago, there is no precedent to think the conclusions are 180 degrees from reality, and so far less reason to think this will be the case.

It is likely man made because noone has been able to explain all the recent warming in the last 3 decades without factoring in enhanced greenhouse effect.

As for the hockey stick, the arguments and counterarguments over it go into very complicated maths and statistics which many people, including me, don't understand, so I have not been able to determine either way who is correct on that issue. It would be nice to know, but it isn't the basis of the theory.

So basically what your telling me is that this was a made up story? As for the last sentence above I again remind you. Imagine what you will 'know' tomorrow.

I would agree to an extent. To think, given the massive industrial expansion not only here but in the world, that we are not haveing an effect of some type is not really plausible. The questions that I have are 1) Is it a bad thing? 2)Will mother nature correct this on her own? 3)What is our actual contribution to CO2 levels taking all sources into account? I tend to think not as high as some believe considering the natural things that give off CO2 like breathing, all plant life on earth as well as oceans. I just think the percentage is smaller than what is being presented. So what percent of all CO2 is man made aside from human respiration? That question would tell us a lot.

Okay we can agree on that, but it is still be presented as evidence despite evidence that the graph itself is incomplete at best, meaning it is being irresponsibly used. That to me is evidence that it is not being used in pursuit of the truth, but in pursuit of an agenda.
