Skeptical scientist has university certification revoked!

The Green/Left never stop trying to stifle dissent. Press release from Dr. David Deming [profdeming@earthlink.net] below. He is a geophysicist and an associate professor of arts and sciences at the University of Oklahoma who has published numerous peer-reviewed research articles. Dr. Deming's Senate December 6, 2006 testimony is available here. University President Boren is a "staunch supporter of Obama". One Fascist supports another, I guess

For ten years or more, professor David Deming has taught a course in environmental geology at the University of Oklahoma. In October 2008, he was informed that the "general education" certification for his course was being revoked. Under the University of Oklahoma system, this means that student enrollment in the course is likely to drop by two-thirds.

This is a course which receives outstanding student evaluations. Professor Deming is well-known to be a global-warming skeptic. In 2006, he testified before the US Senate that media coverage of global warming had descended into "irrational hysteria." See here.

Professor Deming is unaware of any other case in the history of the University of Oklahoma where the "gen ed" certification for a course has been revoked. It would appear possible that professor Deming's position on global warming was a motivating factor. But in this case, the tragedy is that the people being punished are the students, not the professor. Those who wish to express their concern can do so by writing or calling University of Oklahoma President David Boren.

Germany's chief climate alarmist defends his job

If you headed a body named the "Potsdam Instituts fuer Klimafolgenforschung" (Potsdam Institute for Climate Impact Research), you would hardly say there was no impact ("Folgen") would you? The report below is probably the first English-language report of the press conference that I mentioned here on 20th

SEA levels will rise by 1m this century, according to German scientists who warn global warming is happening faster than previously predicted. Citing UN data on climate change, two senior German scientists say that previous predictions were far too cautious and optimistic. Earlier estimates predicted a rise of 18cm to 59cm in sea levels this century. But that estimate is woefully understated, according to Hans Joachim Schellnhuber, who heads the Potsdam Institute for Research on Global Warming Effects [That's not a literal translation but it is a fair one], and Jochem Marotzke, a leading meteorologist. "We now have to expect that the sea level will rise by a metre this century," Professor Schellnhuber said in Berlin.

He said it was "just barely possible" that world governments would be able to limit the rise in average global temperatures to just 2C by the end of the century, if they all strictly adhered to severe limits in carbon dioxide emissions. Those restrictions call for halving greenhouse emissions by 2050 and eliminating CO2 emissions entirely by the end of the century.

But the German researchers said the resulting limited increase in temperature was predicated on strict adherence to those restrictions without exception, and even then there were many variables which could thwart the goals.

Professor Schellnhuber, who is official adviser to German Chancellor Angela Merkel on climate-change issues, said the new findings employed data unavailable to the Intergovernmental Panel on Climate Change for its most recent global warming report. The two experts said the IPCC report had been based on data up to 2005 only, but since then ice loss in the Arctic had doubled or tripled. While Antarctic ice increased]

Professor Schellnhuber said 20 per cent of the loss of the ice sheet on Greenland could be directly linked to the added emissions from new Chinese coal-fired power stations. [Racist!]


Researchers discover 700,000-year-old ice in Arctic - Survived Warmer Temps than today

This complements previous reports that much of the Greenland icecap survived earlier much warmer periods

Canadian researchers studying the Arctic's ancient permafrost have discovered 700,000-year-old ice wedges buried in the soil that have survived earlier periods of global warming, adding complexity to predictions about the impact of contemporary climate change. Duane Froese, an assistant professor in the Department of Earth and Atmospheric Science at the University of Alberta, found what he describes as "the oldest ice in North America" in the Klondike region of Canada's Yukon Territory about 10 feet below the surface.

Because these ice wedges were found under a layer of volcanic ash, researchers from the University of Toronto and the Geological Survey of Canada were able to use a technique known as "fission track dating" of the ash to date it at roughly 700,000 years old. This means the ice was older than the ash and older than the previous record holder - 120,000-year-old ice wedges found in Alaska. "The fact that this ice survived the interglacials about 120,000 and 400,000 years ago, which we think were warmer than present, really illustrates how stubborn permafrost can be in the face of climate warming," Mr. Froese said.

According to a recent article in Ambio, a journal produced by the Royal Swedish Academy of Sciences, permafrost regions occupy about 25 percent of the Northern Hemisphere, with more than 60 percent in Russia. Warming, thawing and degradation of permafrost have already been observed, and there are fears that its shrinkage could lead to increased output of greenhouse gases and unstable structures built on what was once ice-hard ground. Permafrost can vary from almost a mile thick in parts of Siberia to a few feet and turn up over a large region, in scattered regional patches or isolated, the magazine noted. In Canada, permafrost can be found across half the country, in 80 percent of Alaska, 30 percent of Russia, and 20 percent to 30 percent of China and Mongolia, Mr. Froese said. "Permafrost is the glue" that holds the Arctic together and widespread thawing could have dramatic effects on the northern environment, he said.

During the life span of the recently discovered ice wedges, the earth's climate has shifted from long ice ages or glaciations - when woolly mammoths and saber-toothed tigers roamed the Northern Hemisphere - and short warming periods, which may have been much warmer than our current climate. "This ice is not right at the surface, so it survived several earlier periods of global warming that were longer and warmer than ours," Mr. Froese said.....

So far, only one wedge of permafrost this old has been found, but Mr. Moorman said there may be more, and this could change the way environmentalists look at the effects of climate change. The current Canadian Arctic is a place of complex and varied temperatures and snowfalls - the Yukon is dry, and the Western Arctic is heating faster than the Eastern Arctic. [i.e. the effects are local, not global]

Mr. Moorman said that global warming models and grids do not take into account all the complexities of regional variations on the planet, but they are improving. However, the professor notes that 2007 and 2008 have shown a slight reduction in global temperature averages and that low sunspot activity also point to near-term cooling periods.


Record High Number of Polar Bears

Manitoba Conservation does an annual aerial survey from the Churchill area to the Manitoba/Ontario border, roughly the inland range of the polar bears of western Hudson Bay. In late July (the 22nd I believe), they flew the range and counted around 34 bears. Most were still out on the bay feasting on seals. In fact, there were still two little bits of ice floe in southwestern Hudson Bay on August 22nd...! This means that many of the bears stayed out on the ice until mid-August, almost a month later than usual (or at least, earlier than usual for the last decade, but simply similar to the 'glory days' of the early eighties).

So, almost all of the bears visiting Churchill are in really good shape (around ten to twelve in buggyland right now). This seems to have translated through the larger population with 266 polar bears being counted on the fall aerial survey in September. This is the largest number of bears recorded in the history of this survey. Isn't that crazy?!? Life is good for the bears!

Of course, this also leads to the cut in quota for Nunavut's Inuit. Arviat, an economically challenged traditional Inuit town just north of Churchill (and when I say just north, I mean 250 miles) has had their quota wiped out. From 23 polar bears harvested last year, political pressure (not research) has led the government of Nunavut to cut it to three bears. All three bear 'tags' have now been used in self-defence kills (partially because we relocate bears north from Churchill... but that's another story). So, no commercial hunt, no income, no community pride for Arviat... hmmm...


Global warming caused by solar panels

This finding is kind of cute. Alexander Ac has pointed out that a greenhouse gas emitted during the production of solar panels and HDTVs, nitrogen trifluoride (NF3) that is used for cleaning some parts of the gadgets, is about 17,000 times more potent a greenhouse gas than carbon dioxide.

The concentration of NF3 in the atmosphere was artificially increased by a factor of 20 during the last two decades. The measurements of the concentration surpassed the previous estimates by a factor of five.

The present 5,400 tons in the atmosphere - that will stay there for 700+ years - creates the equivalent warming of all Finland's CO2 emissions (I can't tell you how much it is, because of the unknown feedbacks, but the comparisons are pretty reliable).

Given the fact that the solar panels produce about the same percentage of the global energy as Finland, it is reasonable to guess that the state-of-the-art solar panels that would replace fossil fuels would cause a comparable amount of warming per Joule as fossil fuels.


Australia: The young are turning against proposed Warmist laws

Younger people - the strongest supporters of an emissions trading scheme to cut greenhouse gases - are turning against the Rudd Government's 2010 deadline for the implementation of such a scheme. In a reversal of support, those aged between 18 and 34 years old are now most strongly in favour of a delay in the implementation of an emissions trading scheme, The Australian reports.

According to the latest Newspoll survey, taken exclusively for The Australian last weekend, the impact of the financial crisis is turning people against a carbon reduction scheme, or making them want delays. While 72 per cent of those surveyed still favour an emissions trading scheme to drive up the cost of greenhouse gas producing energy, such as electricity and petrol, there is growing opposition.

In July, a Newspoll survey on an emissions trading scheme found that only 11 per cent of people were totally opposed to a carbon emissions reduction scheme and 23 per cent wanted a delay until other major greenhouse gas emitters, particularly China and India, acted. That Newspoll survey confirmed widespread public support for an emissions trading scheme, with 60 per cent of voters backing the adoption of a scheme "regardless of what other countries do". According to the latest Newspoll survey, 21 per cent now oppose an emissions trading scheme under any circumstances.

The Rudd Government has pledged to introduce in 2010 an emissions trading scheme that would push up energy prices by placing a price on carbon. Opposition Leader Malcolm Turnbull has urged the Government to delay the introduction of the scheme. The former leader of the Opposition, Brendan Nelson, lost his authority within the Coalition when he was rolled in shadow cabinet over the suggestion the Opposition should take a tougher stand against an emissions trading scheme.

Dr Nelson said in July the Coalition's greenhouse gas plan would not be popular but "our priority in deciding our policy is to act in Australia's best interest and for Australia not to get too far out in front of the big guys of greenhouse gas emissions such as India and China". "We need to have our economic eyes wide open," Dr Nelson said.

Opposition to an emissions trading scheme has been strongest among men, those aged over 50 and Coalition supporters, while the strongest supporters of a carbon cutting scheme have been among the young, women and Labor supporters. The weekend's survey found the strongest support overall for an emissions trading scheme even if it put up energy costs, was still among the young, women and ALP voters.

What are the effects of global warming? said...

Iv'e heard about this recently. I agree with your position, and there is no need for arguing with this Professor, simply because when the day comes it won't matter. Nature is stronger than us all.
