With each passing day, more and more current and former members of the United Nations’ Intergovernmental Panel on Climate Change are stepping out of the shadows to suggest that this group’s alarmist conclusions concerning global warming are more based in myth than science.

Another member of this growing list of skeptics is Tom V. Segalstad who was an Expert Reviewer for the IPCC’s third assessment report.

As published in Canada’s National Post Saturday, conveniently coincident with Al Gore’s Live Earth concerts (emphasis added throughout):

We are doomed, say climate change scientists associated with the United Nations Intergovernmental Panel on Climate Change, the United Nations body that is organizing most of the climate change research occurring in the world today. Carbon dioxide from man-made sources rises to the atmosphere and then stays there for 50, 100, or even 200 years. This unprecedented buildup of CO2 then traps heat that would otherwise escape our atmosphere, threatening us all.

“This is nonsense," says Tom V. Segalstad, head of the Geological Museum at the University of Oslo and formerly an expert reviewer with the same IPCC. He laments the paucity of geologic knowledge among IPCC scientists -- a knowledge that is central to understanding climate change, in his view, since geologic processes ultimately determine the level of atmospheric CO2.

"The IPCC needs a lesson in geology to avoid making fundamental mistakes," he says. "Most leading geologists, throughout the world, know that the IPCC's view of Earth processes are implausible if not impossible."

Most leading geologists know this? But, how can that be true? After all, Al Gore, Sheryl Crow, Laurie David, and Leonardo DiCaprio – despite having absolutely no expertise concerning this matter – say otherwise. As such, why should we care what someone that actually specializes in this field thinks?

Regardless, the article demonstrated how the IPCC has basically created computer models to predict an end result it wanted while totally ignoring current and past scientific observations regarding CO2’s expected life in the atmosphere:

[W]ith the advent of IPCC-influenced science, the length of time that carbon stays in the atmosphere became controversial. Climate change scientists began creating carbon cycle models to explain what they thought must be an excess of carbon dioxide in the atmosphere. These computer models calculated a long life for carbon dioxide.

Amazingly, the hypothetical results from climate models have trumped the real world measurements of carbon dioxide's longevity in the atmosphere. Those who claim that CO2 lasts decades or centuries have no such measurements or other physical evidence to support their claims.

Neither can they demonstrate that the various forms of measurement are erroneous.

"They don't even try," says Prof. Segalstad. "They simply dismiss evidence that is, for all intents and purposes, irrefutable. Instead, they substitute their faith, constructing a kind of science fiction or fantasy world in the process."

For those that are interested, this is why anthropogenic global warming is regularly referred to as junk science. As Segalstad stated, rather than base future expectations on known past and present observations, the IPCC has created models to predict future events lacking any historical basis.

The article then explained what has been observed, and why what the IPCC is predicting is so ridiculous:

In the real world, as measurable by science, CO2 in the atmosphere and in the ocean reach a stable balance when the oceans contain 50 times as much CO2 as the atmosphere. "The IPCC postulates an atmospheric doubling of CO2, meaning that the oceans would need to receive 50 times more CO2 to obtain chemical equilibrium," explains Prof. Segalstad. "This total of 51 times the present amount of carbon in atmospheric CO2 exceeds the known reserves of fossil carbon-- it represents more carbon than exists in all the coal, gas, and oil that we can exploit anywhere in the world."

So, how does the IPCC resolve this conundrum? Better remove all fluids from proximity:

Also in the real world, Prof. Segalstad's isotope mass balance calculations -- a standard technique in science -- show that if CO2 in the atmosphere had a lifetime of 50 to 200 years, as claimed by IPCC scientists, the atmosphere would necessarily have half of its current CO2 mass. Because this is a nonsensical outcome, the IPCC model postulates that half of the CO2 must be hiding somewhere, in "a missing sink." Many studies have sought this missing sink -- a Holy Grail of climate science research-- without success.

Marvelous, wouldn’t you agree? But, not as good as the Professor’s conclusion:

"It is a search for a mythical CO2 sink to explain an immeasurable CO2 lifetime to fit a hypothetical CO2 computer model that purports to show that an impossible amount of fossil fuel burning is heating the atmosphere," Prof. Segalstad concludes.

"It is all a fiction."

Sadly, this fiction is making a lot of people a lot of money, and threatens to have a huge negative impact on the economies of the developed world especially that of the United States.
