about global warming: Antarctic Chill

Got this posting in from Marc Morano detailing the extensive media coverage on the cooling of the southern hemisphere. It is an excellent anecdote to the recent blast over that piece of ice that broke free.

The fact is that while the north warmed up slightly over the past decades, the south went the other way. The net result was probably zero meaning the net input from CO2 is probably zero. The truth is that over the past year, the already tenuous empirical evidence for global warming has been steadily weakening.

The champions of global warming have been way too quiet on the apparent antarctic cooling trend which appears far more convincing than the northern warming trend.

The antarctic is bounded by a circumpolar wind and current system that naturally imposes a greater confidence in measurement because of natural symmetries.

The northern hemisphere already catches more heat than the south and geography micro manages the heat flow far beyond anything that we know as shown by the sudden melt last summer and the sudden freeze this winter.

The major question now is what level of variation will be experienced this summer.

Media Hype on ‘Melting’ Antarctic Ignores Record Ice Growth

The media is once again hyping an allegedly dire consequence of man-made global warming. This time the media is promoting the ice loss of one tiny fraction of the giant ice-covered continent and completely ignoring the current record ice growth on Antarctica. Contrary to media hype, the vast majority of Antarctica has cooled over the past 50 years and ice coverage has grown to record levels since satellite monitoring began in the 1979, according to peer-reviewed studies and scientists who study the area. (LINK)

Former Weather Channel Meteorologist Joe D’Aleo rejected the hype surrounding the recent Wilkins Ice Shelf collapse in Western Antarctica. “The shattered part of the Wilkins ice sheet was 160 square miles in area, which is just 0.01% of the total current Antarctic ice cover, like an icicle falling from a snow and ice covered roof,” D’Aleo wrote on March 25. (LINK) “We are very likely going to exceed last year’s record [for Southern Hemisphere ice extent]. Yet the world is left with the false impression Antarctica’s ice sheet is also starting to disappear,” D’Aleo added.

Climate scientist Dr. Ben Herman, past director of the Institute of Atmospheric Physics and former Head of the Department of Atmospheric Sciences at the University of Arizona, stated, “It is interesting that all of the AGW (anthropogenic global warming) stories concerning Antarctica are always about what's happening around the [western] peninsula, which seems to be the only place on Antarctica that has shown warming. How about the net ‘no change’ or ‘cooling’ over the rest of the continent, which is probably about 95% of the land mass, not to mention the record sea ice coverage recently.”

Former Colorado State Climatologist Dr. Roger Pielke, Sr., presently senior scientist at the University of Colorado in Boulder, chastised the media’s Antarctic reporting as “typical of the bias that many journalists have.” Pielke wrote on March 25, “The media has ignored in their reporting the increase in Antarctic sea ice cover in recent years, with, at present, a coverage that is well one million square kilometers above average.” Pielke added, “Unfortunately, it appears that most journalists just parrot the perspective of the first news release on these climate issues, without doing any further investigation. If this is inadvertent, they need to be educated in climate science. If deliberate bias, they are clearly advocates and the reporters should be clearly and publically identified as having such a bias. In either case, the public is being misinformed!” (LINK)

But the news media sadly tossed out objectivity and balance when it came to this new Antarctic story. Media headlines blared: Bye-bye, Antarctica? (Salon Magazine 3-26-08); Massive ice shelf collapsing off Antarctica (C/Net News 3- 26-08); Slab of Antarctic ice shelf collapses amid warming (Reuters 3-26-08); Ice shelf 'hangs by a thread' (Sydney Morning Herald 2-26-08).

True to form, Associated Press reporter Seth Borenstein could not allow himself to include any scientists or peer-reviewed studies countering alarm over the allegedly “melting” Antarctic. Borenstein instead hyped alarm by writing on March 27, “Scientists said they are not concerned about a rise in sea level from the latest event, but say it's a sign of worsening global warming.” [Note: Borenstein has a long history of incomplete reporting on global warming. See here and here. Also see related links section below for examples of the media's shoddy environmental reporting. In addition, ABC World News Sunday anchor Dan Harris this week produced a low brow smear segment on atmospheric physicist Dr. Fred Singer, a prominent dissenter of man-made climate fears. ABC News violated basic journalistic standards by citing "anonymous" scientists to attack Dr. Singer. See: here, here, here and here. ]

Yet, if only the media would spend a moment to get beyond the hype and alarmism, they would discover that scientists are already thoroughly debunking the media characterization of the “melting” Antarctic. [Note: 2007 and now 2008 are overwhelmingly turning into the “tipping points” for climate alarmism as new peer-reviewed studies continue to debunk rising CO2 fears, a U.S. Senate minority report reveals over 400 scientists dissented from man-made climate fears, and more and more scientists continue in 2008 to declare themselves skeptical of a man-made climate “crisis.” The Earth’s failure to continue warming has also confounded promoters of man-made climate fear. Here is a sampling of inconvenient developments for climate alarmists in 2008 alone: 1) Oceans Cooling! Scientists puzzled by “mystery of global warming's missing heat”- LINK 2) New Data from NASA’s Aqua satellite is showing “greatly reduced future warming projected as a consequence of carbon dioxide.”- LINK 3) Former NASA Climatologist Dr. Roy Spencer found not one peer-reviewed paper has 'ruled out a natural cause for most of our recent warmth' – LINK 4) UN IPCC in 'Panic Mode' as Earth Fails to Warm, Scientist says – LINK 5) UN IPCC Chairman Rajendra Pachauri “to look into the apparent temperature plateau so far this century.”- LINK 6) New scientific analysis shows Sun “could account for as much as 69% of the increase in Earth's average temperature” – LINK & LINK. 7) An International team of scientists released a March 2008 report to counter UN IPCC, declaring: “Nature, Not Human Activity, Rules the Climate” – LINK 8) MIT Climate Scientist Dr. Richard Lindzen’s new analysis finds the Earth has had “No statistically significant warming since 1995.”- LINK ]

Below are a few samples of what scientists have said in the past few days since the Antarctic “melting” stories have hit the media:

1) Climate Scientist Dr. Ben Herman, past director of the Institute of Atmospheric Physics and former Head of the Department of Atmospheric Sciences at the University of Arizona, is a member of both the Institute for the Study of Planet Earth’s Executive Committee and the Committee on Global Change. Herman commented on March 25:

“That ice [the media is hyping] is just a tiny fraction of the Antarctic ice and probably the increase each winter more than compensates. The ice loss does not show up, at least not yet on the Illinois site, http://arctic.atmos.uiuc.edu/cryosphere, which still shows increasing sea ice heading into [Southern Hemisphere’s] winter. It is interesting that all of the AGW (anthropogenic global warming) stories concerning Antarctica are always about what's happening around the (Western) peninsula, which seems to be the only place on Antarctica that has shown warming. How about the net ‘no change’ or ‘cooling’ over the rest of the continent, which is probably about 95% of the land mass, not to mention the record sea ice coverage recently,” Herman wrote on March 25.

2) Meteorologist Joseph D'Aleo served as the first Director of Meteorology at The Weather Channel, was the Chief Meteorologist at Weather Services International Corporation and served as chairman of the American Meteorological Society's (AMS) Committee on Weather Analysis and Forecasting. D’Aleo commented on his website Icecap.us on March 25:

“The shattered part of the Wilkins ice sheet was 160 square miles in area, which is just 0.01% of the total current Antarctic ice cover (just 0.003% of the extent last September), like an icicle falling from a snow and ice covered roof. And this winter is coming on quickly. The latest satellite images and reports suggest the ice has already refrozen around the broken pieces. In fact the ice is returning so fast, it is running an amazing 60% ahead (4.0 vs 2.5 million square km extent) of last year when it set a new record. The total ice extent is already approaching the second highest level for extent since the measurements began by satellite in 1979 and just a few days into the Southern Hemisphere fall season and 6 months ahead of the peak. We are very likely going to exceed last year’s record [for Southern Hemisphere ice extent]. Yet the world is left with the false impression Antarctica’s ice sheet is also starting to disappear,” D’Aleo wrote on march 25. (LINK)

Other scientists and peer-reviewed studies have recently debunked the notion of a “melting” Antarctic as well.

3) Former Virginia State Climatologist Dr. Patrick Michaels and Paul C. Knappenberger, a senior researcher with New Hope Environmental Services posted comments on Antarctica in February on their website WorldClimateReport.com. Michaels and Knappenberger wrote a February 27, 2008, article titled “Antarctica Ain’t Cooperating”: “Another major article on temperature trends in the Antarctic has appeared in a recent issue of the Journal of Geophysical Research by a team of scientists from Ohio State University, the University of Illinois, and the Goddard Space Flight Center; the research was funded by the National Science Foundation Office of Polar Programs Glaciology Program. […] That is correct – despite all you have heard elsewhere on the subject, the South Pole has been cooling over the past half century. The previous research team also reported that any warming in Antarctica has slowed and the cooling has accelerated in the more recent three decades. According to Monaghan et al., yet another team previously examined Antarctic temperatures and “noted that prior to 1965 the continent-wide annual trends (through 2002) are slightly positive, but after 1965 they are mainly negative (despite warming over the Antarctic Peninsula).” The truth from Antarctica is hard for the greenhouse crusade to accept, and in the long run, the truth from Antarctica might melt away the flimsy, well-publicized claims about global climate change—especially the concerns of a rapid sea level rise.”

4) In addition, the media’s reporting on the alleged “melting” of Antarctica fails to take into account other factors. “Volcano, Not Global Warming Effects, May be Melting an Antarctic Glacier” read a headline in a January 21, 2008, article. The article read in part: Scientists have discovered a layer of volcanic ash and glass shards in Antarctica, evidence of an old eruption by a still active volcano that researchers believe may be contributing to the thinning of Antarctic glacial ice. Hugh F.J. Corr and David G. Vaughan, two scientists with the British Antarctic Survey, recently published their discovery of the volcanic layer in the journal Nature Geoscience. The discovery is unique, according to Dr. Vaughan. He said, “This is the first time we have seen a volcano beneath the ice sheet punch a hole through the ice sheet.” The volcano’s heat could possibly be melting and thinning the ice and raising the speed of the Pine Island Glacier in West Antarctica. (Other links on Antarctic Volcanoes: Map of volcanoes in Antarctica; and NASA Image of Antarctic Peninsula and pacific ring of fire groups of volcanoes. )

5) Another inconvenient fact that the media likes to avoid is Antarctica ice extent GREW to record levels in 2007. A September 11, 2007, article on IceCap.US explained: “While the news focus has been on the lowest ice extent since satellite monitoring began in 1979 for the Arctic, the Southern Hemisphere (Antarctica) has quietly set a new record for most ice extent since 1979. This can be seen on this graphic from this University of Illinois site, The Cryosphere Today, which updated snow and ice extent for both hemispheres daily. The Southern Hemispheric areal coverage is the highest in the satellite record, just beating out 1995, 2001, 2005 and 2006. Since 1979, the trend has been up for the total Antarctic ice extent.” (LINK)

6) A January 12, 2008, peer-reviewed paper in AGU (American Geophysical Union) found “A doubling in snow accumulation in the western Antarctic Peninsula since 1850.” The abstract of the paper by Thomas, E. R., G. J. Marshall, and J. R. McConnell, states: We present results from a new medium depth (136 metres) ice core drilled in a high accumulation site (73.59°S, 70.36°W) on the south-western Antarctic Peninsula during 2007. The Gomez record reveals a doubling of accumulation since the 1850s, from a decadal average of 0.49 mweq y−1 in 1855–1864 to 1.10 mweq y−1 in 1997–2006, with acceleration in recent decades. Comparison with published accumulation records indicates that this rapid increase is the largest observed across the region. (LINK) & (LINK)

7) A February 2007 study reveals Antarctica is not following predicted global warming models. Excerpt: “A new report on climate over the world's southernmost continent shows that temperatures during the late 20th century did not climb as had been predicted by many global climate models." The research was led by David Bromwich, professor of atmospheric sciences in the Department of Geography, and researcher with the Byrd Polar Research Center at Ohio State University. [See: Antarctic temperatures disagree with climate model predictions - (LINK) ]

8) Dr. Duncan Wingham, Professor of Climate Physics at University College London and Director of the Centre for Polar Observation and Modeling, has presented evidence that Antarctic ice is growing. According to a December 15, 2006, article in Canada's National Post, "Early last year at a European Union Space Conference in Brussels, for example, Dr. Wingham revealed that data from a European Space Agency satellite showed Antarctic thinning was no more common than thickening, and concluded that the spectacular collapse of the ice shelves on the Antarctic Peninsula was much more likely to have followed natural current fluctuations than global warming." "One cannot be certain, because packets of heat in the atmosphere do not come conveniently labeled 'the contribution of anthropogenic warming,' " Wingham said, noting that the evidence is not "favorable to the notion we are seeing the results of global warming." Wingham and his colleagues found that 72% of the ice sheet covering the entire land mass of Antarctica is growing at the rate of 5 millimeters per year. "That makes Antarctica a sink, not a source, of ocean water. According to their best estimates, Antarctica will ‘lower global sea levels by 0.08 mm' per year" the National Post article reported. (LINK)

9) Statistician Dr. Bjorn Lomborg, author of The Skeptical Environmentalist and professor at the Copenhagen Business School, questioned former Vice President Al Gore's claims about Antarctica in a January 21, 2007, Wall Street Journal op-ed. "[Gore] considers Antarctica the canary in the mine, but again doesn't tell the full story. He presents pictures from the 2% of Antarctica that is dramatically warming and ignores the 98% that has largely cooled over the past 35 years. The U.N. panel estimates that Antarctica will actually increase its snow mass this century. Similarly, Mr. Gore points to shrinking sea ice in the Northern Hemisphere, but doesn’t mention that sea ice in the Southern Hemisphere is increasing. Shouldn't we hear those facts?" Lomborg added. (LINK)

10) UN scientist Dr. Madhav L. Khandekar, a retired Environment Canada scientist and an expert IPCC reviewer, noted in 2007 that the Southern Hemisphere is COOLING. Dr. Khandekar wrote on August 6, 2007: "In the Southern Hemisphere, the land-area mean temperature has slowly but surely declined in the last few years. The city of Buenos Aires in Argentina received several centimeters of snowfall in early July, and the last time it snowed in Buenos Aires was in 1918! Most of Australia experienced one of its coldest months of June this year. Several other locations in the Southern Hemisphere have experienced lower temperatures in the last few years. Further, the sea surface temperatures over world oceans are slowly declining since mid-1998, according to a recent world-wide analysis of ocean surface temperatures.” (LINK)

11) Ivy League Geologist Dr. Robert Giegengack, the chair of Department of Earth and Environmental Science at the University of Pennsylvania, explained that the Earth has been warming for about 20,000 years, and humans have only been collecting data for about 200 years. "For most of earth's history, the globe has been warmer than it has been for the last 200 years. It has only rarely been cooler," Giegengack said according to a February 2007 article. (LINK) Giegengack further explained that extremely long geologic timescales reveal that "only about 5% of that time has been characterized by conditions on Earth that were so cold that the poles could support masses of permanent ice."
