Scientist's Greenhouse Doubt makes Al Gore Pout

This week a Republican Senate report on Global Warming was released. It contained information from over 400 top scientists who felt that Al Gores Global warming theories were just a tad full of crap. Some of the scientists were even part of the UN committee sharing the Nobel prize with Gore.

"I find the Doomsday picture Al Gore is painting — a six-meter sea level rise, 15 times the IPCC number — entirely without merit," said Dutch atmospheric scientist Hendrik Tennekes, one of the researchers quoted in the report by Republican staff of the Senate Environment and Public Works Committee.

"I protest vigorously the idea that the climate reacts like a home heating system to a changed setting of the thermostat: just turn the dial, and the desired temperature will soon be reached," Mr. Tennekes said in the report.

Gore spokeswoman Kalee Kreider whined that 25 or 30 of the scientists may have received funding from Exxon Mobil Corp. Even if that were true...that leaves 370-375 scientists who think
Gore should retire from science and get a real job.

In the Senate report, environmental scientist David W. Schnare of the U.S. Environmental Protection Agency said he was skeptical because "conclusions about the cause of the apparent warming stand on the shoulders of incredibly uncertain data and models. ... As a policy matter, one has to be less willing to take extreme actions when data are highly uncertain."

The hundreds of others in the report — climatologists, oceanographers, geologists, glaciologists, physicists and paleoclimatologists — voice varying degrees of criticism of the popular global-warming theory. Their testimony challenges the idea that the climate-change debate is "settled" and runs counter to the claim that the number of skeptical scientists is dwindling.

Apparently the world of environmental science is a bit like a bad episode of the Sopranos

Several scientists in the report said many colleagues share their skepticism about man-made climate change but don't speak out publicly for fear of retribution, according to the report. "Many of my colleagues with whom I spoke share these views and report on their inability to publish their skepticism in the scientific or public media," atmospheric scientist Nathan Paldor, professor of Dynamical Meteorology and Physical Oceanography at the Hebrew University of Jerusalem, said in the report.

Here are some of the other comments in that report:

"Even if the concentration of 'greenhouse gases' double, man would not perceive the temperature impact." Oleg Sorochtin of the Institute of Oceanology at the Russian Academy of Sciences

"The hypothesis that solar variability and not human activity is warming the oceans goes a long way to explain the puzzling idea that the Earth's surface may be warming while the atmosphere is not. The [greenhouse-gas] hypothesis does not do this. ... The public is not well served by this constant drumbeat of false alarms fed by computer models manipulated by advocates." David Wojick, expert reviewer for U.N. Intergovernmental Panel on Climate Change

The media is promoting an unprecedented hyping related to global warming. The media and many scientists are ignoring very important facts that point to a natural variation in the climate system as the cause of the recent global warming." Chief Meteorologist Eugenio Hackbart of the MetSul Meteorologia Weather Center in Sao Leopoldo-Rio Grande do Sul, Brazil

"There's no need to be worried. It's very interesting to study [climate change], but there's no need to be worried."Anton Uriarte, a professor of physical geography at the University of the Basque Country in Spain Source Scientists doubt climate change

A legitmate alternate theory to the glacier-ice-melt appeared in this National Science Foundation Report:

Heat From Earth's Magma Contributing To Melting Of Greenland Ice

ScienceDaily (Dec. 18, 2007) — Scientists have discovered what they think may be another reason why Greenland 's ice is melting: a thin spot in Earth's crust is enabling underground magma to heat the ice.

They have found at least one “hotspot” in the northeast corner of Greenland -- just below a site where an ice stream was recently discovered.

The researchers don't yet know how warm the hotspot is. But if it is warm enough to melt the ice above it even a little, it could be lubricating the base of the ice sheet and enabling the ice to slide more rapidly out to sea.

“The behavior of the great ice sheets is an important barometer of global climate change,” said Ralph von Frese, leader of the project and a professor of earth sciences at Ohio State University. “However, to effectively separate and quantify human impacts on climate change, we must understand the natural impacts, too.

“Crustal heat flow is still one of the unknowns -- and it's a fairly significant one, according to our preliminary results.”

Timothy Leftwich, von Frese's former student and now a postdoctoral engineer at the Center for Remote Sensing of Ice Sheets at the University of Kansas, presented the study's early results on Thursday, December 13, 2007, at the American Geophysical Union meeting in San Francisco.

von Frese's team combined gravity measurements of the area taken by a Naval Research Laboratory aircraft with airborne radar measurements taken by research partners at the University of Kansas. The combined map revealed changes in mass beneath the Earth's crust, and the topography of the crust where it meets the ice sheet.

Below the crust is the mantle, the partially molten rocky layer that surrounds the Earth's core. The crust varies in thickness, but is usually tens of miles thick. Even so, the mantle is so hot that temperatures just a few miles deep in the crust reach hundreds of degrees Fahrenheit, von Frese explained.

“Where the crust is thicker, things are cooler, and where it's thinner, things are warmer. And under a big place like Greenland or Antarctica , natural variations in the crust will make some parts of the ice sheet warmer than others,” he said.

The ice thickness, the temperature at the base of the ice, and ground topography all contribute to the forming of an ice stream -- a river of ice that flows within a larger ice sheet. In recent years, Greenland ice streams have been carrying ice out to sea faster, and ice cover on the island has been diminishing.

Once the ice reaches the sea, it melts, and global sea levels rise.

“The complete melting of these continental ice sheets would put much of Florida, as well as New Orleans, New York City and other important coastal population centers, under water,” von Frese said.

The ice sheet in northeast Greenland is especially worrisome to scientists. It had no known ice streams until 1991, when satellites spied one for the first time. Dubbed the Northeastern Greenland Ice Stream, it carries ice nearly 400 miles, from the deepest interior of the island out to the Greenland Sea.

“Ice streams have to have some reason for being there. And it's pretty surprising to suddenly see one in the middle of an ice sheet,” von Frese said.

The newly discovered hotspot is just below the ice stream, and could have caused it to form, the researchers concluded. But what caused the hotspot to form?

“It could be that there's a volcano down there,” he said. “But we think it's probably just the way the heat is being distributed by the rock topography at the base of the ice.”

Collaborator Kees van der Veen began working on the project when he was a visiting associate professor of geological sciences and research scientist at Byrd Polar Research Center at Ohio State. He is now at the University of Kansas.

“Recent observations indicate that the Greenland Ice Sheet is much more active than we ever believed,” van der Veen said. “There have been rapid changes in outlet glaciers, for example. Such behavior is critically linked to conditions at the ice bed. Geothermal heat is an important factor, but until now, our models have not included spatial variations in heat, such as this hotspot.

“Our map is the first attempt at quantifying spatial variations in geo-heat under Greenland -- and it explains why the Northeast Greenland Ice Stream is where it is,” van der Veen added.

To measure actual temperatures beneath the ice, scientists must drill boreholes down to the base of the ice sheet-- a mile or more below the ice surface. The effort and expense make such measurements few and far between, especially in remote areas of northeast Greenland.

For now, the researchers are combining theories of how heat flows through the mantle and crust with the gravity and radar data, to understand how the hotspot is influencing the ice.

Once they finish searching the rest of Greenland for other hotspots, they hope to turn their attention to Antarctica.
