The Idiots Guide to Global Warming

Want to beat your head against the wall? Try to understand the science relevant to global warming. Good luck. There are literally 10s of thousands of scientific reports of all qualities and deeply divided support. Bottom line scientists agree on very little. The scientist have divided into two camps advocates and skeptics. I choose these names because global warming is the most political science on the globe. Why? Money. We can blame Bush senior and Margaret Thatcher. When he came to office spending on climatologic was 150M. When he left office it was 10B. Global warming is big business. 10s of thousands of people are making a living on global warming papers. Each yea their proposals need to be shriller to get additional funding. You also have to recognize that large political organizations have jumped on the issue and are using for their political goals, the environmental movement, and Anti growth Marxists.

After 30 hours of researching the scientific and political crap I will try to guide you to make your own conclusions. There are few facts and lots of agenda oriented papers on both sides of the issue.

Lets start with the few facts. Global warming in the last 100 years is a fact. The earth’s atmosphere has risen 0.7 degrees Celsius. Everyone agrees. Check the graphs:

The other Temp. Graph you need to know. It is taken from the now famous Antarctic ice core samples, which were also used to calculate CO2 levels. Both numbers have a degree of error but the shape of the graph is meaningful. The blue cooling periods represent the ice ages and the red, the intervening warming periods. Note the max temp variation, from –9.5 to near +3 degrees. This is the most important graph in earth climatology because it is caused by the 800 lb gorilla of earth climatology, orbital mechanics. The earth wobbles and tilts in cyclical patterns known as Milankovitch cycles. See the backup for more detail. No matter what else happens, greenhouse gases, nuclear winter, ice ages are going to happen every 100K years. Yea, and it is going to warm in between. Fact. But since 100K years is a long time, nobody cares.

The other fact you need to know is what are green house gases. An honest answer from is:

The major natural greenhouse gases are water vapor, which causes about 36-70% of the greenhouse effect on Earth (not including clouds); carbon dioxide, which causes 9-26%; methane, which causes 4-9%, and ozone, which causes 3-7%. It is not possible to state that a certain gas causes a certain percentage of the greenhouse effect, because the influences of the various gases are not additive. (The higher ends of the ranges quoted are for the gas alone; the lower ends, for the gas counting overlaps.)[2][3] Other greenhouse gases include, but are not limited to, nitrous oxide, sulfur hexafluoride, hydrofluorocarbons, perfluorocarbons and chlorofluorocarbons (see IPCC list of greenhouse gases).

Notice the wild variation. What do you want for 10B dollars? Notice the two 800 lb gorillas above, water vapor and clouds. Wait a minute clouds are not green house gases. True, but clouds effect weather more than any other atmospheric variable. Why are some places deserts? No water vapor and no clouds, just intense solar radiation. Very hot, but it’s a dry heat. Want cooler temperatures you need clouds. The IPCC does not even list water vapor as a greenhouse gas. What is an IPCC? The UN International Panel on Climate Control. But more on that later.

That all you need to know. Huh? The other 10 million pages are hotly contested by scientists on both sides of the issue. Don’t want to read poorly written jargon filled crap, how about some videos. You can find Al Gore’s speech on “An Inconvenient Truth” to The last 20 minutes is all Bush bashing. The DVD released to schools cost $25. Want to know what your kids are being taught; the curriculum guide to the video is here. Want to hear the other side, see the video “The Great Global Warming Swindle”. Both videos can be found backup .

Well there is one more thing you need to know, what is going to happen? Who knows? The same scientists who can’t tell if it is going to rain tomorrow are predicting temperature and climate effects 100 years from now with 3 digit accuracy. The only thing that is certain is that the biggest effect will be in the Northern Hemisphere. Effects will vary greatly, but it is certain that places with moderate weather will get even nicer weather. The north will get warmer and more productive agriculturally. But deserts will get a lot hotter. The Middle East and Northern Africa are screwed.

Politicalization of Global Warming. There is a significant and loosely organized anti human growth crowd in the world. They want the industrialization of the west reversed and the industrialization of Africa prevented and the increases in India and China stopped. After the fall of the Soviet Union and Communism was no longer popular, the commies took over the anti growth movement, and other Global organizations such as the Sierra Club,, Peta and Greenpeace as well as the UN. Patrick Moore cofounder of Greenpeace left because of the anti capitalist influx. With 10B dollars on the table annually, it is no wonder that this crowd is into Global Warming big time. The goals of global warmers are the same as the anti capitalists – stop growth. To quote Al Gore, “there are 3 factors creating environmental catastrophe 1. Population explosion 2. Scientific and Tecnological Revolution. 3. Our way of thinking.” Sounds like an anti growther.

These guys are also fighting each other. The greatest reduction of man made CO2 would occur if oil and coal fired electric plants were replaced by nuclear plants. But the enviromentalist wacos want no nukes. They have won for the last 30 years. Environmentalists have also shut down refineries in the US for the last 30 years. How do you get alternative fuels, you need refineries. Want to destroy the US economy, destroy all the refineries. 100M people would be out of work. It would take 3 days to walk to the unemployment office. No trucks means no food. We would all starve. The anti growth wacos would win.

Global Warming Backup to the Above Post

The following marerial backs up the summary above called the Idiot's Guide to Global Warming.

From Site:
What causes the earth’s climate to change?The level of Carbon Dioxide in the atmosphere is closely related to global temperature. Carbon Dioxide ConcentrationCarbon Dioxide (CO2) is a “greenhouse gas.” It absorbs energy from the Sun and then releases it back into the atmosphere. This “greenhouse effect” keeps the Earth warmer than it would be if this process did not occur. Throughout most of the past 425,000 years the concentration of CO2 has ranged between 180 and 280 parts per million (ppm). When the concentration was at its highest the world was warmer. The Antarctic ice cores that provided evidence of ancient temperatures also contain tiny air bubbles that were trapped as snow accumulated. These bubbles have been analyzed and provide a record of CO2 concentration over time. There is a close correspondence between average global temperature and CO2 concentration.

Are the changes in CO2 concentration causing changes in temperature or is it the other way around? It’s both.A major reason for the drop in atmospheric CO2 as temperatures decrease is that colder oceans are able to dissolve more CO2. There is a constant exchange of CO2 between the atmosphere and the oceans. Gas is dissolved and also released into the atmosphere. The balance is determined largely by temperature. You can see this effect for yourself. Open a bottle of carbonated water or soda. Pour some into each of two glasses. Put one in the refrigerator and leave one at room temperature. Come back in about an hour and take a drink from each. The one in the refrigerator has retained more bubbles. The fluctuations in CO2 level in the atmosphere are part of the Carbon Cycle, a complex process by which carbon moves between the atmosphere, biological organisms, the Earth’s crust and the oceans. The drops in CO2 concentration do not always begin until after a cooling period has begun. Then, as an ice age is ending, the concentrations may remain low for some time into the warming period. This means that the CO2 changes can not be the driving force in initiating these major climate shifts. But as the climate cools, the concentration of CO2 drops and this has a further cooling effect. And as the climate is warming, more CO2 is released into the atmosphere, further increasing global temperatures. This is called a positive feedback loop.

Ice Ages the Milankovitch_Cycle

Milankovitch cycles are the collective effect of changes in the Earth's movements upon its climate, named after Serbian civil engineer and mathematician Milutin Milanković. The eccentricity, axial tilt, and precession of the Earth's orbit vary in several patterns, resulting in 100,000 year ice age cycles of the Quaternary glaciation over the last few million years. The Earth's axis completes one full cycle of precession approximately every 26,000 years. At the same time, the elliptical orbit rotates, more slowly, leading to a 21,000 year cycle between the seasons and the orbit. In addition, the angle between Earth's rotational axis and the normal to the plane of its orbit changes from 21.5 degrees to 24.5 degrees and back again on a 41,000 year cycle. Presently, this angle is 23.44 degrees.
The Milankovitch theory of climate change is not perfectly worked out; in particular, the largest observed response is at the 100,000 year timescale, but the forcing is apparently small at this scale, in regards to the ice ages. Various feedbacks (from carbon dioxide, or from ice sheet dynamics) are invoked to explain this discrepancy.

From Politics of Global Warming

It is a sign of how politicized global warming has become when a father's push for his daughter's junior high school science class to present both sides of the global warming controversy becomes a national story -- with the father being portrayed as the villain.

To recap, Frosty Hardison, the parent of a seventh-grader who attends school in Federal Way, Wash., was troubled to learn that science teacher Kay Walls had planned on showing her class Al Gore's global-warming pic "An Inconvenient Truth" -- without presenting any contrary information.

Hardison is an evangelical Christian who, as The Washington Post reported, sees global warming as "one of the signs" of Judgment Day. That is, Hardison fits the sort of stereotype bound to attract national media attention under the rubric: religious zealot fights science in schools.

The school board put a moratorium on showing the movie -- since lifted -- while it investigated whether Wells was violating a school policy requiring that, when class materials "show bias," educators "point out the biases, and present additional information and perspectives to balance those biases."

On the one hand, it is a sad commentary that districts see a need to restrict teachers' ability to communicate -- and that this country has become so sensitive that parents feel a need to muzzle what teachers can say in class. On the other hand, we've all seen teachers who think their political views are gospel.

In this case, Walls told The Washington Post that she could not find any authoritative articles that counter "An Inconvenient Truth" -- other than a 32-year-old Newsweek article. CNN apparently went to the same school as Walls, as it aired a segment in which University of Maryland Professor Phil Arkin asserted, "I don't think there is legitimately an actual opposing viewpoint to the 'Inconvenient Truth' film."

Allow me to present a few names. Massachusetts Institute of Technollogy's Alfred P. Sloan Professor of Meteorology Richard S. Lindzen complained to the Boston Globe about the "shrill alarmism" of Gore's flick. Neil Frank, who was considered authoritative when he was the director of the National Hurricane Center, told The Washington Post that global warming is "a hoax." Hurricane expert William Gray of Colorado State University believes the Earth will start to cool within 10 years.

UN IPCC Report Rajendra Kumar Pachauri (chairman)

Climate Change 2007, the Fourth Assessment Report (AR4) of the United Nations Intergovernmental Panel on Climate Change (IPCC)
Rajendra Pachauri, the IPCC chair, said at the briefing that the report's broad participation gives it "the stamp of acceptance of all the governments of the world … that really provides the credibility of this massive scientific undertaking."

Hundreds of climate experts and government representatives from 113 countries labored all week in Paris to reach unanimous agreement on the wording of each sentence in the 20-page summary for policymakers.

Rajendra Kumar Pachauri (born August 20, 1940, Nainital, India) was elected chief of the Intergovernmental Panel on Climate Change in 2002. In 2001 he supported a consumer boycott of ExxonMobil for its stance on global warming, saying it was "a good way to put economic pressure on the US." At that time he was serving as the Director of the Board of the Indian Oil Corporation. [1] [2] He has said:
The Third Assessment Report (TAR) of the IPCC clearly states that the risks associated with climate change have the potential to undermine progress towards sustainable development, such as, damages from extreme climate events, water shortage and degraded water quality, food supply disruptions and hunger, land degradation, and diminished human health. [3]
Pachauri also serves as the head of The Energy and Resources Institute, a developing-country institution devoted to sustainable development.
He obtained an M.S. in industrial engineering in 1972, a Ph.D. in industrial engineering, and a Ph.D. in economics from North Carolina State University.
In acknowledgement of his environmental contributions, Pachauri was awarded the Padma Bhushan in 2001 -- one of India's highest civilian awards that recognizes distinguished service to the nation.
Pachauri was criticized for his comparison of Bjorn Lomborg with Adolph Hitler.

Note: the scientists were not in charge the bureaucrates were. The made the final edits and deletions. This issue is too important to leave to the scientists.

By Debra J. Saunders Tuesday, February 6, 2007 UN IPCC Report

The Intergovernmental Panel on Climate Change report released last week was billed as 100 percent proof positive that global warming is real, modern man is to blame and anyone who doubts that is a bad human being.
Readers should be aware that the IPCC Summary for Policymakers was not exactly the work of disinterested scientists completely divorced from politics. Manning explained that the final draft was based on peer-reviewed research, then reviewed "line by line by government delegates."
The fact they are heavy-handed, of course, doesn't mean that they are wrong. It's no problem if you over-hype global warming. The IPCC summary issued a prediction for how much sea level would rise -- by 7 to 23 inches by 2100 -- a big drop from the 20 feet that former Vice President Al Gore warned about in "An Inconvenient Truth." Where's the scorn?

By Jonah Goldberg Friday, February 9, 2007

You get it already. But in the history of trade-offs, never has there been a better one than trading a tiny amount of global warming for a massive amount of global prosperity. Earth got about 0.7 degrees Celsius warmer in the 20th century while it increased its GDP by 1,800 percent, by one estimate. How much of that 0.7 degrees can be laid at the feet of that 1,800 percent is unknowable, but let's stipulate that all of the warming was the result of our prosperity and that this warming is in fact indisputably bad (which is hardly obvious). That's still an amazing bargain. Life expectancies in the United States increased from about 47 years to about 77 years. Literacy, medicine, leisure and even, in many respects, the environment have improved mightily over the course of the 20th century, at least in the prosperous West.

Global Warming: The Origin and Nature of the Alleged Scientific Consensus
Richard S. Lindzen

Richard S. Lindzen is the Alfred P. Sloan Professor of Meteorology at the Massachusetts Institute of Technology.

Most of the literate world today regards "global warming'' as both real and dangerous. Indeed, the diplomatic activity concerning warming might lead one to believe that it is the major crisis confronting mankind. The June 1992 Earth Summit in Rio de Janeiro, Brazil, focused on international agreements to deal with that threat, and the heads of state from dozens of countries attended. I must state at the outset, that, as a scientist, I can find no substantive basis for the warming scenarios being popularly described. Moreover, according to many studies I have read by economists, agronomists, and hydrologists, there would be little difficulty adapting to such warming if it were to occur. Such was also the conclusion of the recent National Research Council's report on adapting to global change. Many aspects of the catastrophic scenario have already been largely discounted by the scientific community. For example, fears of massive sea-level increases accompanied many of the early discussions of global warming, but those estimates have been steadily reduced by orders of magnitude, and now it is widely agreed that even the potential contribution of warming to sea-level rise would be swamped by other more important factors.
To show why I assert that there is no substantive basis for predictions of sizeable global warming due to observed increases in minor greenhouse gases such as carbon dioxide, methane, and chlorofluorocarbons, I shall briefly review the science associated with those predictions.
Summary of Scientific Issues
Before even considering "greenhouse theory,'' it may be helpful to begin with the issue that is almost always taken as a given--that carbon dioxide will inevitably increase to values double and even quadruple present values. Evidence from the analysis of ice cores and after 1958 from direct atmospheric sampling shows that the amount of carbon dioxide in the air has been increasing since 1800. Before 1800 the density was about 275 parts per million by volume. Today it is about 355 parts per million by volume. The increase is generally believed to be due to the combination of increased burning of fossil fuels and before 1905 to deforestation. The total source is estimated to have been increasing exponentially at least until 1973. From 1973 until 1990 the rate of increase has been much slower, however. About half the production of carbon dioxide has appeared in the atmosphere.
Predicting what will happen to carbon dioxide over the next century is a rather uncertain matter. By assuming a shift toward the increased use of coal, rapid advances in the third world's standard of living, large population increases, and a reduction in nuclear and other nonfossil fuels, one can generate an emissions scenario that will lead to a doubling of carbon dioxide by 2030--if one uses a particular model for the chemical response to carbon dioxide emissions. The Intergovernmental Panel on Climate Change Working Group I's model referred to that as the "business as usual'' scenario. As it turns out, the chemical model used was inconsistent with the past century's record; it would have predicted that we would already have about 400 parts per million by volume. An improved model developed at the Max Planck Institute in Hamburg shows that even the "business as usual'' scenario does not double carbon dioxide by the year 2100. It seems unlikely moreover that the indefinite future of energy belongs to coal. I also find it difficult to believe that technology will not lead to improved nuclear reactors within fifty years.
Nevertheless, we have already seen a significant increase in carbon dioxide that has been accompanied by increases in other minor greenhouse gases such as methane and chlorofluorocarbons. Indeed, in terms of greenhouse potential, we have had the equivalent of a 50 percent increase in carbon dioxide over the past century. The effects of those increases are certainly worth studying--quite independent of any uncertain future scenarios.
The Greenhouse Effect.
The crude idea in the common popular presentation of the greenhouse effect is that the atmosphere is transparent to sunlight (apart from the very significant reflectivity of both clouds and the surface), which heats the Earth's surface. The surface offsets that heating by radiating in the infrared. The infrared radiation increases with increasing surface temperature, and the temperature adjusts until balance is achieved. If the atmosphere were also transparent to infrared radiation, the infrared radiation produced by an average surface temperature of minus eighteen degrees centigrade would balance the incoming solar radiation (less that amount reflected back to space by clouds). The atmosphere is not transparent in the infrared, however. So the Earth must heat up somewhat more to deliver the same flux of infrared radiation to space. That is what is called the greenhouse effect.
The fact that the Earth's average surface temperature is fifteen degrees centigrade rather than minus eighteen degrees centigrade is attributed to that effect. The main absorbers of infrared in the atmosphere are water vapor and clouds. Even if all other greenhouse gases (such as carbon dioxide and methane) were to disappear, we would still be left with over 98 percent of the current greenhouse effect. Nevertheless, it is presumed that increases in carbon dioxide and other minor greenhouse gases will lead to significant increases in temperature. As we have seen, carbon dioxide is increasing. So are other minor greenhouse gases. A widely held but questionable contention is that those increases will continue along the path they have followed for the past century.
The simple picture of the greenhouse mechanism is seriously oversimplified. Many of us were taught in elementary school that heat is transported by radiation, convection, and conduction. The above representation only refers to radiative transfer. As it turns out, if there were only radiative heat transfer, the greenhouse effect would warm the Earth to about seventy-seven degrees centigrade rather than to fifteen degrees centigrade. In fact, the greenhouse effect is only about 25 percent of what it would be in a pure radiative situation. The reason for this is the presence of convection (heat transport by air motions), which bypasses much of the radiative absorption.

What is really going on is schematically illustrated in Figure 1. The surface of the Earth is cooled in large measure by air currents (in various forms including deep clouds) that carry heat upward and poleward. One consequence of this picture is that it is the greenhouse gases well above the Earth's surface that are of primary importance in determining the temperature of the Earth. That is especially important for water vapor, whose density decreases by about a factor of 1,000 between the surface and ten kilometers above the surface. Another consequence is that one cannot even calculate the temperature of the Earth without models that accurately reproduce the motions of the atmosphere. Indeed, present models have large errors here--on the order of 50 percent. Not surprisingly, those models are unable to calculate correctly either the present average temperature of the Earth or the temperature ranges from the equator to the poles. Rather, the models are adjusted or "tuned" to get those quantities approximately right.
It is still of interest to ask what we would expect a doubling of carbon dioxide to do. A large number of calculations show that if this is all that happened, we might expect a warming of from .5 to 1.2 degrees centigrade. The general consensus is that such warming would present few, if any, problems. But even that prediction is subject to some uncertainty because of the complicated way the greenhouse effect operates. More important, the climate is a complex system where it is impossible for all other internal factors to remain constant. In present models those other factors amplify the effects of increasing carbon dioxide and lead to predictions of warming in the neighborhood of four to five degrees centigrade. Internal processes within the climate system that change in response to warming in such a manner as to amplify the response are known as positive feedbacks. Internal processes that diminish the response are known as negative feedbacks. The most important positive feedback in current models is due to water vapor. In all current models upper tropospheric (five to twelve kilometers) water vapor--the major greenhouse gas--increases as surface temperatures increase. Without that feedback, no current model would predict warming in excess of 1.7 degrees centigrade--regardless of any other factors. Unfortunately, the way current models handle factors such as clouds and water vapor is disturbingly arbitrary. In many instances the underlying physics is simply not known. In other instances there are identifiable errors. Even computational errors play a major role. Indeed, there is compelling evidence for all the known feedback factors to actually be negative. In that case, we would expect the warming response to carbon dioxide doubling alone to be diminished.
It is commonly suggested that society should not depend on negative feedbacks to spare us from a "greenhouse catastrophe.'' What is omitted from such suggestions is that current models depend heavily on undemonstrated positive feedback factors to predict high levels of warming. The effects of clouds have been receiving the closest scrutiny. That is not unreasonable. Cloud cover in models is poorly treated and inaccurately predicted. Yet clouds reflect about seventy-five watts per square meter. Given that a doubling of carbon dioxide would change the surface heat flux by only two watts per square meter, it is evident that a small change in cloud cover can strongly affect the response to carbon dioxide. The situation is complicated by the fact that clouds at high altitudes can also supplement the greenhouse effect. Indeed, the effects of clouds in reflecting light and in enhancing the greenhouse effect are roughly in balance. Their actual effect on climate depends both on the response of clouds to warming and on the possible imbalance of their cooling and heating effects.
Similarly, factors involving the contribution of snow cover to reflectivity serve, in current models, to amplify warming due to increasing carbon dioxide. What happens seems reasonable enough; warmer climates presumably are associated with less snow cover and less reflectivity--which, in turn, amplify the warming. Snow is associated with winter when incident sunlight is minimal, however. Moreover, clouds shield the Earth's surface from the sun and minimize the response to snow cover. Indeed, there is growing evidence that clouds accompany diminishing snow cover to such an extent as to make that feedback factor negative. If, however, one asks why current models predict that large warming will accompany increasing carbon dioxide, the answer is mostly due to the effect of the water vapor feedback. Current models all predict that warmer climates will be accompanied by increasing humidity at all levels. As already noted, such behavior is an artifact of the models since they have neither the physics nor the numerical accuracy to deal with water vapor. Recent studies of the physics of how deep clouds moisturize the atmosphere strongly suggest that this largest of the positive feedbacks is not only negative, but very large.

Not only are there major reasons to believe that models are exaggerating the response to increasing carbon dioxide, but, perhaps even more significantly, the models' predictions for the past century incorrectly describe the pattern of warming and greatly overestimate its magnitude. The global average temperature record for the past century or so is irregular and not without problems. It does, however, show an average increase in temperature of about .45 degree centigrade plus or minus .15 degree centigrade with most of the increase occurring before 1940, followed by some cooling through the early 1970s and a rapid (but modest) temperature increase in the late 1970s. As noted, we have already seen an increase in "equivalent'' carbon dioxide of 50 percent. Thus, on the basis of models that predict a four degree centigrade warming for a doubling of carbon dioxide we might expect to have seen a warming of two degrees centigrade already. If, however, we include the delay imposed by the oceans' heat capacity, we might expect a warming of about one degree centigrade--which is still twice what has been observed. Moreover, most of that warming occurred before the bulk of the minor greenhouse gases were added to the atmosphere. Figure 2 shows what might have been expected for models with differing sensitivities to a doubling of carbon dioxide. What we see is that the past record is most consistent with an equilibrium response to a doubling of about 1.3 degrees centigrade--assuming that all the observed warming was due to increasing carbon dioxide. There is nothing in the record that can be distinguished from the natural variability of the climate, however.
If one considers the tropics, that conclusion is even more disturbing. There is ample evidence that the average equatorial sea surface has remained within plus or minus one degree centigrade of its present temperature for billions of years, yet current models predict average warming of from two to four degrees centigrade even at the equator. It should be noted that for much of the Earth's history, the atmosphere had much more carbon dioxide than is currently anticipated for centuries to come. I could, in fact, go on at great length listing the evidence for small responses to a doubling of carbon dioxide; there are space constraints, however.
Consensus and the Current "Popular Vision''
Many studies from the nineteenth century on suggested that industrial and other contributions to increasing carbon dioxide might lead to global warming. Problems with such predictions were also long noted, and the general failure of such predictions to explain the observed record caused the field of climatology as a whole to regard the suggested mechanisms as suspect. Indeed, the global cooling trend of the 1950s and 1960s led to a minor global cooling hysteria in the 1970s. All that was more or less normal scientific debate, although the cooling hysteria had certain striking analogues to the present warming hysteria including books such as The Genesis Strategy by Stephen Schneider and Climate Change and World Affairs by Crispin Tickell--both authors are prominent in support of the present concerns as well--"explaining'' the problem and promoting international regulation. There was also a book by the prominent science writer Lowell Ponte (The Cooling) that derided the skeptics and noted the importance of acting in the absence of firm, scientific foundation. There was even a report by the National Research Council of the U.S. National Academy of Sciences reaching its usual ambiguous conclusions. But the scientific community never took the issue to heart, governments ignored it, and with rising global temperatures in the late 1970s the issue more or less died. In the meantime, model calculations--especially at the Geophysical Fluid Dynamics Laboratory at Princeton--continued to predict substantial warming due to increasing carbon dioxide. Those predictions were considered interesting, but largely academic, exercises--even by the scientists involved.
The present hysteria formally began in the summer of 1988, although preparations had been put in place at least three years earlier. That was an especially warm summer in some regions, particularly in the United States. The abrupt increase in temperature in the late 1970s was too abrupt to be associated with the smooth increase in carbon dioxide. Nevertheless, James Hansen, director of the Goddard Institute for Space Studies, in testimony before Sen. Al Gore's Committee on Science, Technology and Space, said, in effect, that he was 99 percent certain that temperature had increased and that there was some greenhouse warming. He made no statement concerning the relation between the two.
Despite the fact that those remarks were virtually meaningless, they led the environmental advocacy movement to adopt the issue immediately. The growth of environmental advocacy since the 1970s has been phenomenal. In Europe the movement centered on the formation of Green parties; in the United States the movement centered on the development of large public interest advocacy groups. Those lobbying groups have budgets of several hundred million dollars and employ about 50,000 people; their support is highly valued by many political figures. As with any large groups, self-perpetuation becomes a crucial concern. "Global warming'' has become one of the major battle cries in their fundraising efforts. At the same time, the media unquestioningly accept the pronouncements of those groups as objective truth.
Within the large-scale climate modelling community--a small subset of the community interested in climate--however, the immediate response was to criticize Hansen for publicly promoting highly uncertain model results as relevant to public policy. Hansen's motivation was not totally obvious, but despite the criticism of Hansen, the modelling community quickly agreed that large warming was not impossible. That was still enough for both the politicians and advocates who have generally held that any hint of environmental danger is a sufficient basis for regulation unless the hint can be rigorously disproved. That is a particularly pernicious asymmetry, given that rigor is generally impossible in environmental sciences.
Other scientists quickly agreed that with increasing carbon dioxide some warming might be expected and that with large enough concentrations of carbon dioxide the warming might be significant. Nevertheless, there was widespread skepticism. By early 1989, however, the popular media in Europe and the United States were declaring that "all scientists'' agreed that warming was real and catastrophic in its potential.
As most scientists concerned with climate, I was eager to stay out of what seemed like a public circus. But in the summer of 1988 Lester Lave, a professor of economics at Carnegie Mellon University, wrote to me about being dismissed from a Senate hearing for suggesting that the issue of global warming was scientifically controversial. I assured him that the issue was not only controversial but also unlikely. In the winter of 1989 Reginald Newell, a professor of meteorology at the Massachusetts Institute of Technology, lost National Science Foundation funding for data analyses that were failing to show net warming over the past century. Reviewers suggested that his results were dangerous to humanity. In the spring of 1989 I was an invited participant at a global warming symposium at Tufts University. I was the only scientist among a panel of environmentalists. There were strident calls for immediate action and ample expressions of impatience with science. Claudine Schneider, then a congressman from Rhode Island, acknowledged that "scientists may disagree, but we can hear Mother Earth, and she is crying.'' It seemed clear to me that a very dangerous situation was arising, and the danger was not of "global warming'' itself.
In the spring of 1989 I prepared a critique of global warming, which I submitted to Science, a magazine of the American Association for the Advancement of Science. The paper was rejected without review as being of no interest to the readership. I then submitted the paper to the Bulletin of the American Meteorological Society, where it was accepted after review, rereviewed, and reaccepted--an unusual procedure to say the least. In the meantime, the paper was attacked in Science before it had even been published. The paper circulated for about six months as samizdat. It was delivered at a Humboldt conference at M.I.T. and reprinted in the Frankfurter Allgemeine.
In the meantime, the global warming circus was in full swing. Meetings were going on nonstop. One of the more striking of those meetings was hosted in the summer of 1989 by Robert Redford at his ranch in Sundance, Utah. Redford proclaimed that it was time to stop research and begin acting. I suppose that that was a reasonable suggestion for an actor to make, but it is also indicative of the overall attitude toward science. Barbara Streisand personally undertook to support the research of Michael Oppenheimer at the Environmental Defense Fund, although he is primarily an advocate and not a climatologist. Meryl Streep made an appeal on public television to stop warming. A bill was even prepared to guarantee Americans a stable climate.
By the fall of 1989 some media were becoming aware that there was controversy (Forbes and Reader's Digest were notable in that regard). Cries followed from environmentalists that skeptics were receiving excessive exposure. The publication of my paper was followed by a determined effort on the part of the editor of the Bulletin of the American Meteorological Society, Richard Hallgren, to solicit rebuttals. Such articles were prepared by Stephen Schneider and Will Kellogg, a minor scientific administrator for the past thirty years, and those articles were followed by an active correspondence mostly supportive of the skeptical spectrum of views. Indeed, a recent Gallup poll of climate scientists in the American Meteorological Society and in the American Geophysical Union shows that a vast majority doubts that there has been any identifiable man-caused warming to date (49 percent asserted no, 33 percent did not know, 18 percent thought some has occurred; however, among those actively involved in research and publishing frequently in peer-reviewed research journals, none believes that any man-caused global warming has been identified so far). On the whole, the debate within the meteorological community has been relatively healthy and, in this regard, unusual.
Outside the world of meteorology, Greenpeace's Jeremy Legett, a geologist by training, published a book attacking critics of warming---especially me. George Mitchell, Senate majority leader and father of a prominent environmental activist, also published a book urging acceptance of the warming problem (World on Fire: Saving an Endangered Earth). Sen. Gore recently published a book (Earth in the Balance: Ecology and the Human Spirit). Those are just a few examples of the rapidly growing publications on warming. Rarely has such meager science provoked such an outpouring of popularization by individuals who do not understand the subject in the first place.
The activities of the Union of Concerned Scientists deserve special mention. That widely supported organization was originally devoted to nuclear disarmament. As the cold war began to end, the group began to actively oppose nuclear power generation. Their position was unpopular with many physicists. Over the past few years, the organization has turned to the battle against global warming in a particularly hysterical manner. In 1989 the group began to circulate a petition urging recognition of global warming as potentially the great danger to mankind. Most recipients who did not sign were solicited at least twice more. The petition was eventually signed by 700 scientists including a great many members of the National Academy of Sciences and Nobel laureates. Only about three or four of the signers, however, had any involvement in climatology. Interestingly, the petition had two pages, and on the second page there was a call for renewed consideration of nuclear power. When the petition was published in the New York Times, however, the second page was omitted. In any event, that document helped solidify the public perception that "all scientists'' agreed with the disaster scenario. Such a disturbing abuse of scientific authority was not unnoticed. At the 1990 annual meeting of the National Academy of Sciences, Frank Press, the academy's president, warned the membership against lending their credibility to issues about which they had no special knowledge. Special reference was made to the published petition. In my opinion what the petition did show was that the need to fight "global warming'' has become part of the dogma of the liberal conscience--a dogma to which scientists are not immune.
At the same time, political pressures on dissidents from the "popular vision'' increased. Sen. Gore publicly admonished "skeptics'' in a lengthy New York Times op-ed piece. In a perverse example of double-speak he associated the "true believers'' in warming with Galileo. He also referred, in another article, to the summer of 1988 as the Kristallnacht before the warming holocaust.
The notion of "scientific unanimity'' is currently intimately tied to the Working Group I report of the Intergovernmental Panel on Climate Change issued in September 1990. That panel consists largely of scientists posted to it by government agencies. The panel has three working groups. Working Group I nominally deals with climate science. Approximately 150 scientists contributed to the report, but university representation from the United States was relatively small and is likely to remain so, since the funds and time needed for participation are not available to most university scientists. Many governments have agreed to use that report as the authoritative basis for climate policy. The report, as such, has both positive and negative features. Methodologically, the report is deeply committed to reliance on large models, and within the report models are largely verified by comparison with other models. Given that models are known to agree more with each other than with nature (even after "tuning''), that approach does not seem promising. In addition, a number of the participants have testified to the pressures placed on them to emphasize results supportive of the current scenario and to suppress other results. That pressure has frequently been effective, and a survey of participants reveals substantial disagreement with the final report. Nonetheless, the body of the report is extremely ambiguous, and the caveats are numerous. The report is prefaced by a policymakers' summary written by the editor, Sir John Houghton, director of the United Kingdom Meteorological Office. His summary largely ignores the uncertainty in the report and attempts to present the expectation of substantial warming as firmly based science. The summary was published as a separate document, and, it is safe to say that policymakers are unlikely to read anything further. On the basis of the summary, one frequently hears that "hundreds of the world's greatest climate scientists from dozens of countries all agreed that....'' It hardly matters what the agreement refers to, since whoever refers to the summary insists that it agrees with the most extreme scenarios (which, in all fairness, it does not). I should add that the climatology community, until the past few years, was quite small and heavily concentrated in the United States and Europe.
While the International Panel on Climate Change's reports were in preparation, the National Research Council in the United States was commissioned to prepare a synthesis of the current state of the global change situation. The panel chosen was hardly promising. It had no members of the academy expert in climate. Indeed, it had only one scientist directly involved in climate, Stephen Schneider, who is an ardent environmental advocate. It also included three professional environmental advocates, and it was headed by a former senator, Dan Evans. The panel did include distinguished scientists and economists outside the area of climate, and, perhaps because of this, the report issued by the panel was by and large fair. The report concluded that the scientific basis for costly action was absent, although prudence might indicate that actions that were cheap or worth doing anyway should be considered. A subcommittee of the panel issued a report on adaptation that argued that even with the more severe warming scenarios, the United States would have little difficulty adapting. Not surprisingly, the environmentalists on the panel not only strongly influenced the reports, but failing to completely have their way, attempted to distance themselves from the reports by either resigning or by issuing minority dissents. Equally unsurprising is the fact that the New York Times typically carried reports on that panel on page 46. The findings were never subsequently discussed in the popular media--except for claims that the reports supported the catastrophic vision. Nevertheless, the reports of that panel were indicative of the growing skepticism concerning the warming issue.
Indeed, the growing skepticism is in many ways remarkable. One of the earliest protagonists of global warming, Roger Revelle, the late professor of ocean sciences at Scripps Institution of Oceanography who initiated the direct monitoring of carbon dioxide during the International Geophysical Year (1958), coauthored with S. Fred Singer and Chauncy Starr a paper recommending that action concerning global warming be delayed insofar as current knowledge was totally inadequate. Another active advocate of global warming, Michael McElroy, head of the Department of Earth and Planetary Sciences at Harvard, has recently written a paper acknowledging that existing models cannot be used to forecast climate.
One might think that such growing skepticism would have some influence on public debate, but the insistence on "scientific unanimity'' continues unabated. At times, that insistence takes some very strange forms. Over a year ago, Robert White, former head of the U.S. Weather Bureau and currently president of the National Academy of Engineering, wrote an article for Scientific American that pointed out that the questionable scientific basis for global warming predictions was totally inadequate to justify any costly actions. He did state that if one were to insist on doing something, one should only do things that one would do even if there were no warming threat. Immediately after that article appeared, Tom Wicker, a New York Times columnist and a confidant of Sen. Gore, wrote a piece in which he stated that White had called for immediate action on "global warming.'' My own experiences have been similar. In an article in Audubon Stephen Schneider states that I have "conceded that some warming now appears inevitable.'' Differences between expectations of unmeasurable changes of a few tenths of a degree and warming of several degrees are conveniently ignored. Karen White in a lengthy and laudatory article on James Hansen that appeared in the New York Times Sunday Magazine reported that even I agreed that there would be warming, having "reluctantly offered an estimate of 1.2 degrees.'' That was, of course, untrue.
Most recently, I testified at a Senate hearing conducted by Sen. Gore. There was a rather arcane discussion of the water vapor in the upper troposphere. Two years ago, I had pointed out that if the source of water vapor in that region in the tropics was from deep clouds, then surface warming would be accompanied by reduced upper level water vapor. Subsequent research has established that there must be an additional source--widely believed to be ice crystals thrown off by those deep clouds. I noted that that source too probably acts to produce less moisture in a warmer atmosphere. Both processes cause the major feedback process to become negative rather than positive. Sen. Gore asked whether I now rejected my suggestion of two years ago as a major factor. I answered that I did. Gore then called for the recording secretary to note that I had retracted my objections to "global warming.'' In the ensuing argument, involving mostly other participants in the hearing, Gore was told that he was confusing matters. Shortly thereafter, however, Tom Wicker published an article in the New York Times that claimed that I had retracted my opposition to warming and that that warranted immediate action to curb the purported menace. I wrote a letter to the Times indicating that my position had been severely misrepresented, and, after a delay of over a month, my letter was published. Sen. Gore nonetheless claims in his book that I have indeed retracted my scientific objections to the catastrophic warming scenario and also warns others who doubt the scenario that they are hurting humanity.
Why, one might wonder, is there such insistence on scientific unanimity on the warming issue? After all, unanimity in science is virtually nonexistent on far less complex matters. Unanimity on an issue as uncertain as "global warming'' would be surprising and suspicious. Moreover, why are the opinions of scientists sought regardless of their field of expertise? Biologists and physicians are rarely asked to endorse some theory in high energy physics. Apparently, when one comes to "global warming,'' any scientist's agreement will do.
The answer almost certainly lies in politics. For example, at the Earth Summit in Rio, attempts were made to negotiate international carbon emission agreements. The potential costs and implications of such agreements are likely to be profound for both industrial and developing countries. Under the circumstances, it would be very risky for politicians to undertake such agreements unless scientists "insisted.'' Nevertheless, the situation is probably a good deal more complicated than that example suggests.
The Temptation and Problems of "Global Warming''
As Aaron Wildavsky, professor of political science at Berkeley, has quipped, "global warming'' is the mother of all environmental scares. Wildavsky's view is worth quoting. "Warming (and warming alone), through its primary antidote of withdrawing carbon from production and consumption, is capable of realizing the environmentalist's dream of an egalitarian society based on rejection of economic growth in favor of a smaller population's eating lower on the food chain, consuming a lot less, and sharing a much lower level of resources much more equally.'' In many ways Wildavsky's observation does not go far enough. The point is that carbon dioxide is vitally central to industry, transportation, modern life, and life in general. It has been joked that carbon dioxide controls would permit us to inhale as much as we wish; only exhaling would be controlled. The remarkable centrality of carbon dioxide means that dealing with the threat of warming fits in with a great variety of preexisting agendas--some legitimate, some less so: energy efficiency, reduced dependence on Middle Eastern oil, dissatisfaction with industrial society (neopastoralism), international competition, governmental desires for enhanced revenues (carbon taxes), and bureaucratic desires for enhanced power.
The very scale of the problem as popularly portrayed and the massive scale of the suggested responses have their own appeal. The Working Group I report of the Intergovernmental Panel on Climate Change suggested, for example, that a 60 percent reduction in carbon dioxide emissions might be needed. Such a reduction would call for measures that would be greater than those that have been devoted to war and defense. And just as defense has dealt with saving one's nation, curbing "global warming'' is identified with saving the whole planet! It may not be fortuitous that this issue is being promoted at just the moment in history when the cold war is ending.
Major agencies in the United States, hitherto closely involved with traditional approaches to national security, have appropriated the issue of climate change to support existing efforts. Notable among those agencies are NASA, the Department of Defense, and the Department of Energy. The cold war helped spawn a large body of policy experts and diplomats specializing in issues such as disarmament and alliance negotiations. In addition, since the Yom Kippur War, energy has become a major component of national security with the concomitant creation of a large cadre of energy experts. Many of those individuals see in the global change issue an area in which to continue applying their skills. Many scientists also feel that national security concerns formed the foundation for the U.S. government's generous support of science. As the urgency of national security, traditionally defined, diminishes, there is a common feeling that a substitute foundation must be established. "Saving the planet'' has the right sort of sound to it. Fundraising has become central to environmental advocates' activities, and the message underlying some of their fundraising seems to be "pay us or you'll fry.''
Clearly, "global warming'' is a tempting issue for many very important groups to exploit. Equally clearly, though far less frequently discussed, are the profound dangers in exploiting that issue. As we shall also see, there are good reasons why there has been so little discussion of the downside of responding to "global warming.''
A parochial issue is the danger to the science of climatology. As far as I can tell, there has actually been reduced funding for existing climate research. That may seem paradoxical, but, at least in the United States, the vastly increased number of scientists and others involving themselves in climate as well as the gigantic programs attaching themselves to climate have substantially outstripped the increases in funding. Perhaps more important are the pressures being brought to bear on scientists to get the "right'' results. Such pressures are inevitable, given how far out on a limb much of the scientific community has gone. The situation is compounded by the fact that some of the strongest proponents of "global warming'' in Congress are also among the major supporters of science (Sen. Gore is notable among those). Finally, given the momentum that has been building up among so many interest groups to fight "global warming,'' it becomes downright embarrassing to support basic climate research. After all, one would hate to admit that one had mobilized so many resources without the basic science's being in place. Nevertheless, given the large increase in the number of people associating themselves with climatology and the dependence of much of that community on the perceived threat of warming, it seems unlikely that the scientific community will offer much resistance. I should add that as ever greater numbers of individuals attach themselves to the warming problem, the pressures against solving the problem grow proportionally; an inordinate number of individuals and groups depend on the problem's remaining.
In addition to climatologists, are there other groups that are at risk? Here, one might expect that industry could be vulnerable, and, indeed, it may be. At least in the United States, however, industries seem to be primarily concerned with improving their public image, often by supporting environmental activists. Moreover, some industries have become successful at profiting from environmental regulation. The most obvious example is the waste management industry. Even electric utility companies have been able to use environmental measures to increase the base on which their regulated profits are calculated. It is worth noting that about 1.7 trillion dollars have been spent on the environment over the past decade. The environment, itself, qualifies as one of our major industries.
If Wildavsky's scenario is correct, the major losers would be ordinary people. Wealth that could have been used to raise living standards in much of the world would be squandered. Living standards in the developed world would decrease. Regulatory apparatuses would restrict individual freedom on an unprecedented scale. Here too, however, one cannot expect much resistance to proposed actions--at least not initially. Public perceptions, under the influence of extensive, deceptive, and one-sided publicity, can become disconnected from reality. For example, Alabama has had a pronounced cooling trend since 1935. Nevertheless, a poll among professionals in Alabama found that about 95 percent of the participants believed that the climate had been warming over the past fifty years and that the warming was due to the greenhouse effect. Public misperceptions coupled with a sincere desire to "save the planet'' can force political action even when politicians are aware of the reality.
What the above amounts to is a societal instability. At a particular point in history, a relatively minor suggestion or event serves to mobilize massive interests. While the proposed measures may be detrimental, resistance is largely absent or coopted. In the case of climate change, the probability that the proposed regulatory actions would for the most part have little impact on climate, regardless of the scenario chosen, appears to be of no consequence.
Modelling and Societal Instability
So far I have emphasized the political elements in the current climate hysteria. There can be no question, however, that scientists are abetting this situation. Concerns about funding have already been mentioned. There is, however, another perhaps more important element to the scientific support. The existence of modern computing power has led to innumerable modelling efforts in many fields. Supercomputers have allowed us to consider the behavior of systems seemingly too complex for other approaches. One of those systems is climate. Not surprisingly, there are many problems involved in modelling climate. For example, even supercomputers are inadequate to allow long-term integrations of the relevant equations at adequate spatial resolutions. At presently available resolutions, it is unlikely that the computer solutions are close to the solutions of the underlying equations. In addition, the physics of unresolved phenomena such as clouds and other turbulent elements is not understood to the extent needed for incorporation into models. In view of those problems, it is generally recognized that models are at present experimental tools whose relation to the real world is questionable.
While there is nothing wrong in using those models in an experimental mode, there is a real dilemma when they predict potentially dangerous situations. Should scientists publicize such predictions since the models are almost certainly wrong? Is it proper to not publicize the predictions if the predicted danger is serious? How is the public to respond to such predictions? The difficulty would be diminished if the public understood how poor the models actually are. Unfortunately, there is a tendency to hold in awe anything that emerges from a sufficiently large computer. There is also a reluctance on the part of many modellers to admit to the experimental nature of their models lest public support for their efforts diminish. Nevertheless, with poor and uncertain models in wide use, predictions of ominous situations are virtually inevitable--regardless of reality.
Such weak predictions feed and contribute to what I have already described as a societal instability that can cascade the most questionable suggestions of danger into major political responses with massive economic and social consequences. I have already discussed some of the reasons for this instability: the existence of large cadres of professional planners looking for work, the existence of advocacy groups looking for profitable causes, the existence of agendas in search of saleable rationales, and the ability of many industries to profit from regulation, coupled with an effective neutralization of opposition. It goes almost without saying that the dangers and costs of those economic and social consequences may be far greater than the original environmental danger. That becomes especially true when the benefits of additional knowledge are rejected and when it is forgotten that improved technology and increased societal wealth are what allow society to deal with environmental threats most effectively. The control of societal instability may very well be the real challenge facing us.

The first (and sometimes last) stop in the global-warming debate is the question, Is it real? The answer seems to be yes. Ground-based and oceanic temperature records show warming of about three-quarters of a degree Celsius in the last century. About half of that warming, however, occurred before World War II and is widely thought to be related to solar activity. Satellite and weather-balloon records, which do not go back as far, show less warming in the late 20th century than the land-based stations.
What's causing this warming? We don't know. As the vice president of the U.N.'s Intergovernmental Panel on Climate Change (IPCC), Yury Izrael, wrote bluntly last month, "There is no proven link between human activity and global warming." Given the extreme variability of global temperature, warming might simply be statistical noise. It might result from solar and/or volcanic activity. It might be caused by industrial emissions. And it might come from some combination of the three.
What do most scientists suspect is going on? The best way to ascertain the "scientific consensus" is to look at the latest report of the IPCC (released in 2001), which purports to summarize the state of scientific knowledge on global warming. Here's what it says: "Most of the observed warming over the last 50 years is likely to have been due to the increase in greenhouse gas concentrations." The report finds that it is "unlikely (bordering on very unlikely) to be entirely the result of internal variability," and that "natural forcing alone [i.e., solar and/or volcanic activity] is unlikely to explain the increased rate of global warming since the middle of the 20th century."
The promiscuous use of such vague terms as "likely" and "unlikely" by scientists who are trained in precision speaks volumes about how much is unknown. At the very least, such language makes it impossible to accept the Greens' claim that "the debate is over," particularly given all the uncertainty -- fully discussed in the IPCC report -- regarding long-term climate records and important data on atmospheric feedbacks. In fact, uncertainty about future climate conditions is greater in the 2001 IPCC report than it was in the 1995 IPCC report.
Should we worry about such modest warming? From an ecological perspective, probably not. Because water vapor is responsible for 94 percent of the natural greenhouse effect, industrial greenhouse gases have a greater impact in dry air masses than in wet ones. Fully 78 percent of the warming has been concentrated in the driest air masses, which are primarily found during the winter (when 69 percent of the warming has occurred), at night, and in the northern latitudes.
The fact that winter nighttime lows in the Northern Hemisphere aren't quite as cold as they used to be need not cause anyone to panic -- and there seems not to be an increased incidence of the destructive weather events that would follow from warming in wet air masses. According to the IPCC, "[T]here is little sign of long-term changes in tropical storm intensity and frequency," and "no compelling evidence" that local severe-weather events are on the rise. Most important, "no significant acceleration in the rate of sea level rise during the 20th century has been detected." Precipitation in the northern hemisphere has likely increased by a meager 0.5-1 percent a decade, but "no comparable systematic changes in precipitation have been detected in broad latitudinal averages over the Southern Hemisphere."

My Notes on Al Gores “An Inconvenient Truth”

IPCC is the most accurate scientific assessment.

Global Warming is caused by human activity.

Casualties of global warming: glaciers will all melt.

Medevil warming period is not correct.

Graph of temp and CO2 “looks like they go together”

CO2 higher today than in 400,000 years.

Antartic Ice melt in the past made sea levels rise 23 ft (Al your IPCC Report is claiming 19-23 inches, oops)

Alaskan temperatures have gone up 8 degrees.
1 degree change at the equator = 12 degrees change at the Noth Pole which will make climate more violent.

CO2 will not just double but go up 4 times causing 60% loss of soil moisture
Greenhouse gases = CO2 (Al read the IPCC report there are a few more )
US reponsible for more greenhouse gases than S. America, Africa and China combined.
Why people don’t believe – a massive and well organized disinformation campaign lavishly funded by polluters.

Pretending there is disagreement in the scientific community about a broad based consent.

Scientist are taking money from big industry to say global warming is not a fact.
Republican talking points – scientific uncertainty is an issue.
Bush has Industry suing the government to reduce funding for global warming.

Notes on the “ Great Global Warming Swindle”

Little Ice Age occurred in the 14th century.

Medevil warming period occurred from 1100 – 1300

IPCC states that the warmest period was the Holocene Maximum 4-8000 years ago. Polar bears survived this warming period.

Patrick Michaels Uva. Current temp rise of 0.7 degrees celsius mostly occurred before 1940.

1940-1975 temp went down as industrialization went up. OOPs.
Carbon dioxide in atmosphere today = 0.054% total.

Water vapor = 95%.

Climate variability is a result of the temp variation between the equator and the noth pole. The greater the difference the more violent the global weather that year. 64 % of Global Warming occurs at night in the nothern latitudes. Therefore global warming will result in less violent weather. Sorry Al.

Richard Lidzen MIT warming should occur first in the troposphere 10-12 miles up.

John Christie NASA lead IPCC author If greenhouse gases cause global warming the temp should increase as you go up to 10 miles, but surface temps are warmer. Therefore surface temp rise is not due to greenhouse gases.
Al gore forgot to mention that CO2 rises lag 800 years after temp increase.
Volcanoes produce more CO2 than humans.

Animals and bacteria produces even more. Dying vegetation more.

The ocean is the biggest storage of CO2 and the biggest emitter.

Carl Wunsch MIT changes in ocean teps lag 800 years from the cause due to the mass.

Past 150 years the ocean temp has risen 0.5 degrees celsius.

Edward Mornder, astronomer, Sun Spots result in higher solar energy emmissions.

little Ice Age had fewer sun spots.

Eigel Fris-Christensen 1991 Danish Meterorlogical Inst.

400 years of sun spot data. Solar emmission increases with the number of sun spots.
Clouds produce a cooling effect. Formed by sub atomic particles from cosmic rays (protons)

High solar wind results in less cosmic rays. 500M years of recorded congruence.

Tim Ball U of Winnipeg, all climate models are based on man made CO2 increases.

John Christy UAB 1000 years ago Greenland was warmer did not cause significant melting.
