Computer Models Vastly Exaggerate The Effects Of Carbon Dioxide On Climate

Is Professor Happer, the author of the following editorial a racist, and an enemy of society?  See the previous blog post about some people who think he is.  Judge for yourself.  Who is correct, people who question the premise that man-made carbon dioxide emissions are causing global warming and destructive climate change, or those who scare us into believing we must "cap and trade" (tax) "carbon emissions" in order to save Mother Earth and our own health and future?

Who is more credible, this esteemed Princeton Professor, or Al Gore and President Obama?

Global Warming Models Are Wrong Again

The observed response of the climate to more CO2 is not in good agreement with predictions.

By WILLIAM HAPPER

During a fundraiser in Atlanta earlier this month, President Obama is reported to have said: "It gets you a little nervous about what is happening to global temperatures. When it is 75 degrees in Chicago in the beginning of March, you start thinking. On the other hand, I really have enjoyed nice weather."
What is happening to global temperatures in reality? The answer is: almost nothing for more than 10 years. Monthly values of the global temperature anomaly of the lower atmosphere, compiled at the University of Alabama from NASA satellite data, can be found at the website http://www.drroyspencer.com/latest-global-temperatures/. The latest (February 2012) monthly global temperature anomaly for the lower atmosphere was minus 0.12 degrees Celsius, slightly less than the average since the satellite record of temperatures began in 1979.

The lack of any statistically significant warming for over a decade has made it more difficult for the United Nations Intergovernmental Panel on Climate Change (IPCC) and its supporters to demonize the atmospheric gas CO2 which is released when fossil fuels are burned. The burning of fossil fuels has been one reason for an increase of CO2 levels in the atmosphere to around 395 ppm (or parts per million), up from preindustrial levels of about 280 ppm.

CO2 is not a pollutant. Life on earth flourished for hundreds of millions of years at much higher CO2 levels than we see today. Increasing CO2 levels will be a net benefit because cultivated plants grow better and are more resistant to drought at higher CO2 levels, and because warming and other supposedly harmful effects of CO2 have been greatly exaggerated. Nations with affordable energy from fossil fuels are more prosperous and healthy than those without.

The direct warming due to doubling CO2 levels in the atmosphere can be calculated to cause a warming of about one degree Celsius. The IPCC computer models predict a much larger warming, three degrees Celsius or even more, because they assume changes in water vapor or clouds that supposedly amplify the direct warming from CO2. Many lines of observational evidence suggest that this "positive feedback" also has been greatly exaggerated.

There has indeed been some warming, perhaps about 0.8 degrees Celsius, since the end of the so-called Little Ice Age in the early 1800s. Some of that warming has probably come from increased amounts of CO2, but the timing of the warming—much of it before CO2 levels had increased appreciably—suggests that a substantial fraction of the warming is from natural causes that have nothing to do with mankind.

Frustrated by the lack of computer-predicted warming over the past decade, some IPCC supporters have been claiming that "extreme weather" has become more common because of more CO2. But there is no hard evidence this is true. After an unusually cold winter in 2011 (December 2010-February 2011) the winter of 2012 was unusually warm in the continental United States. But the winter of 2012 was bitter in Europe, Asia and Alaska.

Weather conditions similar to 2012 occurred in the winter of 1942, when the U.S. Midwest was unusually warm, and when the Wehrmacht encountered the formidable forces of "General Frost" in a Russian winter not unlike the one Russians just had.

Large fluctuations from warm to cold winters have been the rule for the U.S., as one can see from records kept by the National Ocean and Atmospheric Administration, NOAA. For example, the winters of 1932 and 1934 were as warm as or warmer than the 2011-2012 one and the winter of 1936 was much colder.

Nightly television pictures of the tragic destruction from tornadoes over the past months might make one wonder if the frequency of tornadoes is increasing, perhaps due to the increasing levels of CO2 in the atmosphere. But as one can read at Andrew Revkin's New York Times blog, dotearth, "There is no evidence of any trend in the number of potent tornadoes (category F2 and up) over the past 50 years in the United States, even as global temperatures have risen markedly."
 
Like winter temperatures, the numbers, severity and geographical locations of tornadoes fluctuate from year-to-year in ways that are correlated with the complicated fluid flow patterns of the oceans and atmosphere, the location of the jet stream, El Niño or La Niña conditions of the tropical Pacific Oceans, etc.

Princeton physicist William Happer argues that computer models vastly exaggerate the effects of carbon dioxide on climate and that CO2 may in fact be beneficial.

As long as the laws of nature exist, we will have tornadoes. But we can save many more lives by addressing the threat of tornadoes directly—for example, with improved and more widely dispersed weather radars, and with better means for warning the people of endangered areas—than by credulous support of schemes to reduce "carbon footprints," or by funding even more computer centers to predict global warming.

But these ominous predictions are based on computer models. It is important to distinguish between what the climate is actually doing and what computer models predict. The observed response of the climate to more CO2 is not in good agreement with model predictions.

We need high-quality climate science because of the importance of climate to mankind. But we should also remember the description of how science works by the late, great physicist, Richard Feynman:
"In general we look for a new law by the following process. First we guess it. Then we compute the consequences of the guess to see what would be implied if this law that we guessed is right. Then we compare the result of the computation to nature, with experiment or experience; compare it directly with observation, to see if it works. If it disagrees with experiment it is wrong."
 
The most important component of climate science is careful, long-term observations of climate-related phenomena, from space, from land, and in the oceans. If observations do not support code predictions—like more extreme weather, or rapidly rising global temperatures—Feynman has told us what conclusions to draw about the theory.

Mr. Happer is a professor of physics at Princeton.

Yet Another Prominent Scientist Challenges The Myth Of Man-Caused Global Warming

This time it is prominent Princeton University Physics Professor William Happer. Pay close attention to what he says. He has far, far more education and experience than most global warming alarmists.
There is little question we need a major national and international debate on the subject of global warming and whether man's carbon dioxide emissions are causing some kind of harmful climate change. This is not merely an academic question, but one that carries with it profound economic, social, and political consequences. We need to figure this out and get it right. The debate can not be over. This is no time to act rashly and irresponsibly.

Professor denies global warming theory

Physics professor William Happer [pictured] GS ’64 has some tough words for scientists who believe that carbon dioxide is causing global warming.

“This is George Orwell. This is the ‘Germans are the master race. The Jews are the scum of the earth.’ It’s that kind of propaganda,” Happer, the Cyrus Fogg Brackett Professor of Physics, said in an interview. “Carbon dioxide is not a pollutant. Every time you exhale, you exhale air that has 4 percent carbon dioxide. To say that that’s a pollutant just boggles my mind. What used to be science has turned into a cult.”

Happer served as director of the Office of Energy Research in the U.S. Department of Energy under President George H.W. Bush and was subsequently fired by Vice President Al Gore, reportedly for his refusal to support Gore’s views on climate change. He asked last month to be added to a list of global warming dissenters in a Senate Environment and Public Works Committee report. The list includes more than 650 experts who challenge the belief that human activity is contributing to global warming.

Though Happer has promulgated his skepticism in the past, he requested to be named a skeptic in light of the inauguration of President-elect Barack Obama, whose administration has, as Happer notes, “stated that carbon dioxide is a pollutant” and that humans are “poisoning the atmosphere.”

Happer maintains that he doubts there is any strong anthropogenic influence on global temperature.

“All the evidence I see is that the current warming of the climate is just like past warmings. In fact, it’s not as much as past warmings yet, and it probably has little to do with carbon dioxide, just like past warmings had little to do with carbon dioxide,” Happer explained.

Happer is chair of the board of directors at the George C. Marshall Institute, a nonprofit conservative think tank known for its attempts to highlight uncertainties about causes of global warming. The institute was founded by former National Academy of Sciences president and prominent physicist Frederick Seitz GS ’34, who publicly expressed his skepticism of the claim that global warming is caused by human activity. Seitz passed away in March 2008.

In 2007, the Institute reported $726,087 in annual operating expenses, $205,156 of which was spent on climate change issues, constituting the largest portion of its program expenses, according to its I-990 tax exemption form.

In a statement sent to the Senate as part of his request, Happer explained his reasoning for challenging the climate change movement, citing his research and scientific knowledge.

“I have spent a long research career studying physics that is closely related to the greenhouse effect, for example, absorption and emission of visible and infrared radiation, and fluid flow,” he said in the statement. “Based on my experience, I am convinced that the current alarm over carbon dioxide is mistaken.”

Geosciences professor Michael Oppenheimer, the lead author of the fourth report of the Intergovernmental Panel on Climate Change (IPCC) — whose members, along with Gore, received the 2007 Nobel Peace Prize — said in an interview that Happer’s claims are “simply not true.”

Oppenheimer, director of the Wilson School’s Program in Science, Technology and Environmental Policy, stressed that the preponderance of evidence and majority of expert opinion points to a strong anthropogenic influence on rising global temperatures, noting that he advises Happer to read the IPCC’s report and publish a scientific report detailing his objections to its findings.

The University is home to a number of renowned climate change scientists. Ecology and evolutionary biology professor Stephen Pacala and mechanical and aerospace engineering professor Robert Socolow, who are co-chairs of the Carbon Mitigation Initiative (CMI) and the Princeton Environmental Institute, developed a set of 15 “stabilization wedges.” These are existing technologies that would, by the year 2054, each prevent 1 billion tons of carbon emissions. They argue that the implementation of seven of these wedges would be needed to reach a target level of carbon in the atmosphere.

Neither Pacala nor Socolow could be reached for comment.

Happer said that he is alarmed by the funding that climate change scientists, such as Pacala and Socolow, receive from the private sector.

“Their whole career depends on pushing. They have no other reason to exist. I could care less. I don’t get a dime one way or another from the global warming issue,” Happer noted. “I’m not on the payroll of oil companies as they are. They are funded by BP.”

The CMI has had a research partnership with BP since 2000 and receives $2 million each year from the company. In October, BP announced that it would extend the partnership — which had been scheduled to expire in 2010 — by five years.

The Marshall Institute, however, has received at least $715,000 from the ExxonMobil Foundation and Corporate Giving division from 1998 to 2006, according to the company’s public reports. Though Exxon has challenged the scientific models for proving the human link to climate change in the past, its spokesmen have said that the company’s stance has been misunderstood. Others say the company has changed its stance.

Happer explained that his beliefs about climate change come from his experience at the Department of Energy, at which Happer said he supervised all non-weapons energy research, including climate change research. Managing a budget of more than $3 billion, Happer said he felt compelled to make sure it was being spent properly. “I would have [researchers] come in, and they would brief me on their topics,” Happer explained. “They would show up. Shiny faces, presentation ready to go. I would ask them questions, and they would be just delighted when you asked. That was true of almost every group that came in.”

The exceptions were climate change scientists, he said.

“They would give me a briefing. It was a completely different experience. I remember one speaker who asked why I wanted to know, why I asked that question. So I said, you know I always ask questions at these briefings … I often get a much better view of [things] in the interchange with the speaker,” Happer said. “This guy looked at me and said, ‘What answer would you like?’ I knew I was in trouble then. This was a community even in the early 1990s that was being turned political. [The attitude was] ‘Give me all this money, and I’ll get the answer you like.’ ”

Happer said he is dismayed by the politicization of the issue and believes the community of climate change scientists has become a veritable “religious cult,” noting that nobody understands or questions any of the science.

He noted in an interview that in the past decade, despite what he called “alarmist” claims, there has not only not been warming, there has in fact been global cooling. He added that climate change scientists are unable to use models to either predict the future or accurately model past events.

“There was a baseball sage who said prediction is hard, especially of the future, but the implication was that you could look at the past and at least second-guess the past,” Happer explained. “They can’t even do that.”

Happer cited an ice age at the time of the American Revolution, when Londoners skated on the Thames, and warm periods during the Middle Ages, when settlers were able to farm southern portions of Greenland, as evidence of naturally occurring fluctuations that undermine the case for anthropogenic influence.

“[Atmospheric carbon dioxide concentration] was exactly the same then. It didn’t change at all,” he explained. “So there was something that was making the earth warm and cool that modelers still don’t really understand.”

The problem does not in fact exist, he said, and society should not sacrifice for nothing.

“[Climate change theory has] been extremely bad for science. It’s going to give science a really bad name in the future,” he said. “I think science is one of the great triumphs of humankind, and I hate to see it dragged through the mud in an episode like this.”
