The Antarctic Wilkins Ice Shelf Collapse: Media recycles photos and storylines from previous years

Those masters of disaster are at it again, and it appears our friendly scientists at that National Snow and Ice Data Center (NSIDC) help this story along each year.

Thanks to WUWT reader Ron de Haan who spotted this on:

http://www.appinsys.com/GlobalWarming/AntarcticWilkinsIceShelf.htm

Note the dates for these two stories are a year apart, but use the same photo.

It seems that not only is the photography recycled, so is the storyline. It seems to happen every year, about this time. Note the photos show shear failure and cracks, not melted ice. Shear failure is mostly mechanical-stress related, though ice does tend to be more brittle at colder temperatures.

National Geographic reported this story headline last year, March 25th 2008

PHOTO IN THE NEWS: Giant Antarctic Ice Shelf Collapses

Don’t let the date in the upper right fool you, thats just an automatic “today’s date” javascript element found in many webpages.

From the Nat Geo story:

“[It’s] an event we don’t get to see very often,” Ted Scambos, lead scientist at the U.S. National Snow and Ice Data Center in Boulder, Colorado, said in a press statement.

Now, how is it that an ice shelf breaks up in the spring of 2008 and again in the spring of 2009 and it’s “not very often”? Hmmm.

It seems NSIDC’s Ted Scambos gets around.  Doing a Google search for

Wilkins ice shelf + “Ted Scambos”

yields about 4,930 results. Yep, he sure gets the word out every year.

Ted Scambos said something similar in 1999:

“On the southwest side of the peninsula, the Wilkins ice shelf retreated nearly 1,100 square kilometers in early March of last year [1998], said Scambos. … Within a few years, much of the Wilkins ice shelf will likely be gone” [http://www.heatisonline.org/contentserver/objecthandlers/index.cfm?ID=3209&Method=Full&PageCall=&Title=Antarctic%20Ice%20Shelf%20Break-Up%20Accelerates&Cache=False].

But, as can be seen from the following January 1996 and March 2008 images, there has been hardly any change in a decade. Look at the photos below from the appinsys web site:

wilkins_satimages_2008-1996

But wait, there’s more examples of that “not very often” Wilkins ice shelf breakup, again from the appinsys web site:

As the following historical satellite images of the Wilkins Ice Shelf show, the disintegration / re-growth is an annual event (winter ice re-growth season; summer melt season).

Wilkins Ice Shelf Dec 1993
Wilkins Ice Shelf Dec 1993
Wilkins disintegration in Feb 1994
Wilkins disintegration in Feb 1994
Wilkins in Oct 2003, on the mend
Wilkins in Oct 2003, on the mend
Wilkins in Mar 2004 - breaking up again
Wilkins in Mar 2004 - breaking up again
Wilkins in Nov 2008 - icing up
Wilkins in Nov 2008 - icing up
Wilkins in Feb 2009 - uh oh!
Wilkins in Feb 2009 - uh oh!

But we just know warming is involved, NSIDC says so:

The MSNBC 2008 article reports on a NSIDC article which states:

“NSIDC Lead Scientist Ted Scambos, who first spotted the disintegration in March, said, “We believe the Wilkins has been in place for at least a few hundred years. But warm air and exposure to ocean waves are causing a break-up.”

The closest station to the Wilkins Ice Shelf in the NOAA Global Historical Climate Network database is Rothera Point. The following figure shows the historical data for Rothera Point, with monthly temperatures in blue and the annual January temperature in red. Summer (Dec – Mar) temperatures have not increased – the 2000s January temperatures are similar to the 1940s (the oldest data available). So why does NSIDC’s Scambos blame it on air temperatures?

[http://www.appinsys.com/GlobalWarming/climgraph.aspx?pltparms=GHCNT100MJanJanI194020080900110MR70089062000x]

The appinsys article goes on to talk about ocean currents and sea surface temperatures being a contributor, and it is worth the read. See it here.

The real question is, how often are we going to see the Wilkins Ice Shelf be a lead news story as poster child for “global warming” to illustrate ice loss in Antarctica that is actually growing.

I guess as long as we have NSIDC’s Ted Scambos to help the media, it will be “something we get to see fairly often”.

Man, if people walk on that ice just imagine the devastation!
“Yes Mike, if there are places on earth where even a blind horse can’t inflict any damage, it is at the Poles.”
If… IF they would really like to do something about ice, perhaps it would make more sense to keep icebergs off the Arctic sea ice. But then again, perhaps that is not as big a problem as I imagine it to be.

NSIDC is a division of INSTAAR -the Institute of Arctic and Alpine Research (INSTAAR), a the University of Colorado at Boulder.
INSTAAR’s director is James White, a geologist and paleoclimatologist with an environmentally correct agenda, ie, one driven to enviro-wacky notions like ”sustainability.”
http://instaar.colorado.edu/people/bios/white.html
Thus, last week, when White faced the Competitive Enterprise Institute’s Chris Horner to debate global warming at Colorado Christian University, White argued that
we should take climate change as a warning to lighten our footprint — “training wheels for sustainability.” In endorsing the Kyoto Treaty’s agenda, White pleaded ”What is our responsibility to the Earth?” In other words, it isn’t science that determines our policies towards climate change, but the right environmental ethic.
At the debate, an auditorium for 300 overflowed with another 100 ouside. Amazingly, the Denver Post’s environmental reporter refused to cover this event, saying that having Horner there made it “not a debate… not news.”
But getting back to the egregious ”reporting” and ”recycling” by NSIDC (above), this treatment makes perfect sense as White’s cause trumps mere ”science.” How shameful.

I notice at NSIDC that the photo for Wilkins, 10 April 2009 ( MODIS visible) is exactly the same as the photo for AVHRR image (visible) 20 February 1994.
The very same photo. Please confirm that my eyes are not deceiving me.

Your argument is the weakest form of rebuttal. The “But what about X” argument. You do not address the point at all. Seems Wilkins collapses all the time, and recovers. Seems also that media outlets like to put up dramatic pictures of it and tell us that it’s another fearful portent of things to come from global warming. Unfortunately, this isn’t true, hence your reverting to the “But what about X” argument.

Today’s best quote from the Catlin crew – 4/18/09 – Temp -25C
“Crossing open water is now par for the course with polar travel. As spring progresses, the warmer temperatures cause the ice to melt and break up, meaning the frequency and size of leads increases. The emergence of open water at this stage of the survey is typical for this time of year and will become almost a daily occurrence towards the end of the expedition. So, today was a practice run for the days ahead…. ”
They truly are advancing science – now finding ice that melts at -25c

“One warning sign that a dangerous warming is beginning in Antarctica, will be a breakup of ice shelves in the Antarctic Peninsula just south of the January 0C isotherm; the ice shelf in the Prince Gustav Channel, and the Wordie Ice Shelf; the ice shelf in George VI Sound, and the ice shelf in Wilkins Sound.”
Of course, the fact that all these shelves have disappeared (Wilkins being the last survivor)

Rubbish. The George IV Sound iceshelf is still intact and its by far the largest.
The ice shelf in the Prince Gustav Channel is much smaller and on the other side of the Peninsula. It broke up prior to 1995. Although this icesheet hasn’t existed for most of the last 5,000 years. So we have just returned to the Holocene norm.

Mike Bryant (08:50:38) : “[…]The most recent warming started in the seventies, a few years later the 1979 became the year of greatest sea ice extent in the arctic since 1972 til the present time. As the Earth warmed, the arctic sea ice extent has been on a downward trend. 1998 was the warmest year Earth-wide, and then nine years later, we had the lowest extent of Arctic sea ice. Since then the Earth’s temperature has declined and the sea ice extent appears to be making a comeback.
I’m sure this will be torn to pieces, but it sure seems to fit the facts.

I don’t think anyone has replied to this comment of yours.
IMHO it is exactly as one would expect. Over short timescales, warm/cool conditions should not correlate as much with ice amount as with rate of change of ice amount. Just as albedo relates to rate of change of ocean temp not absolute ocean temp.
What I think is happening is that the Earth’s climate over decadal+ timescales is driven by ocean temperature, which is in turn driven by albedo, which may well turn out to be driven by GCRs (we need the CLOUD experiment at CERN to be more sure), which we know are significantly driven by the sun.
Albedo was decreasing up to 2000, then increased again. So the oceans were warming fastest in 2000, then the rate of warming slowed, and in about 2006 they started cooling again. But when warm oceans just start cooling they are still warm, so they are still melting ice until they have cooled for a while. Consequently, the Arctic ice went on melting in 2007.
It is very hard to nail these things to specific years, and things like the El Nino that caused 1998 to be the warmest year (by surface temp) add a lot of noise, so it would be easy to argue about the dates.
For the basic principle, I suppose you could look at how the derivative of a sine wave is 90 deg out of sync with the sine wave itself.

Mike and Mike: Also, the earth functions as a pump, absorbing more energy in the tropics than it admits and pumping heat toward the poles where more energy is emitted than absorbed. There is a lag built into that process.
Yet another reason I’m sure that the Arctic is now freezing back up.

I simply say, it is ice, it breaks up and reforms and this fascination around multi-year float ice at one location
You are confusing sea ice with glacial ice. Once glacial iceshelf ice breaks up it doesn’t reform. It floats away as icebergs.
An iceshelf (like any glacier) is a constant process of new ice forming near the source pushing older ice closer to where it will break up and melt. This takes many thousands of years for the, small by Antarctic standards, Antarctic Peninsula glaciers. Also note the Wilkins iceshelf forms as glaciers on Alexander Island (about the size of Long Island) and not the Antarctic Peninsula.
Whether a glacier is advancing or retreating (gaining or losing ice mass) is determined by many factors and will vary over many timescales (decade, century, millenium).
We can say with reasonable confidence that Antarctic Peninsula iceshelfs/glaciers have retreated over the last century, advanced over the last millenium or two, and have seen a decrease in retreat over the last decade.
Whether the last decade signals a new trend is the same debate as whether the surface temperatures are in a new downward trend or just a temporary slowdown in the warming.

I sent this message to Al Gore in an attempt to calm his hysteria.
The Earth is simply changing due to inherent chemical properties. Every negative aspect of the global warming theory can be also realized as a positive……..we must realize nature’s laws and let our current scientific beliefs fall by the wayside.
THE HEART OF MAN ADRIFT AS EARTH AND HER WATERS SPEAK
It is the Earth who speaks all in creation, as housed memory of our very existence, of all energies required to sustain all languages in one mind, all pulsing in one heart, all answers in one word, are housed here for any individual on her surface who asks, desiring any message at any time to be delivered.
We fear, failing to understand.
We worry needlessly.
We accuse without cause.
We place blame where none should be.
We suffer the pain of disease, ignoring the cause.
We feign the wages of war, when opposition is our invention.
We grieve for those who suffer endless hunger, yet the world has plenty.
We are without answers, for we have failed in our duty to ask.
All is as it should be. Everything on this Earth, every man woman and child, every animal, every plant was conceived by this great planet. It is she who dreamed of life in the first place. Our experience a gift.
The Earth is alive. She lives and dies just as we do. Her cycles extend through billions of years, so we fail to grasp the concept.
All we see before our eyes is a miracle. The living, dying and resurrection of Earth.
Nothing we could possibly do could alter course of her invention. We are to gain insight through the changes, understand her cycles and document memory of these for all who are to follow.
IT IS SHE WHO SPEAKS.
When our actions taint our thoughts, and we come to believe we’ve gone against our morals, our values and concern for one another, we must re-think and come to understand the truth.
We have no power. We are not the force. The decision for all that is or ever will be lies in realm of Earth’s creation.
We have not caused the buildup of CO2 in her atmosphere. She has by exhaling density of rest matter.
We have not forced the melting of ice caps. She has by speeding up the rotation of her core.
We are not behind the depletion of ozone. She is, so that it can be utilized in conjunction with other elements to heal herself.
We live within realm of Earth’s dream and purpose. In time of change she will create the reaction to attain equilibrium.
WATER
Imagine yourself adrift in an open sea. There are no obstructions as it is fluid, each particle miniscule, blending balanced in an equal exchange, giving to the freedom and flight of evaporation and the steadfast horizontal viscous flow. Always moving and swirling in motion is this never ending draw of viscosity.
Sailing now with the wind are we, in direction of the sun’s horizon and ever so merrily drifting with the tide.
And so it is, you realize how much your are alike. Yet all the while knowing there are limits and boundary to which you must adhere. For the likeness and the flows opposition also finds you there.
A sustaining world she is within, and yet she exists within another to nurture their being. Without her we would cease to be, for our balance is one timed with nature as is the sun to rise and each plant to grow in exchange of hydrogen and oxygen’s glow. Of these things man has mind to reason and know. There is life within her seizing and reigning at depths untold. A place unseen that we are oblivious to. Her calculated meandering encroaches as her insiduous nature becomes insolent, invading as vast boundary surmounts the land.
We are not unlike her. Our behaviors manifest deep within too. And we, just as she, react to the stresses placed upon us. She seeks no vengeance as the crest gains momentum of the internal force which drives her, nor does she seek to extinguish life in the depths of the waves trough.
Earth’s mass too beckons this internal force which shifts dense boundary as she engulfs the shore, ravaging and eroding all that vulnerable above as so below, drawing unto her every ridge the sand that the wind so meticulously heaped into foothills. She creates a pass through which she might travel, moving slowly now over land and through valleys like a glacier, cresting with momentum to cradle and nurture the land, pleading for health of the water’s purging cleanse.
And as these waves settle gently now on new shores, submerged beneath pressures we fear, is a life without knowledge of her fierce, engulfing motion. She evenly and warmly fulfills their needs with elements and minerals pouring forth, bonding the constituents of harmony to reason survival. Life to feed life, giving without question and in no need of answers. For what is, just is.
She is the sea. A mightly ocean encapsulated within a vast boundary of fluid dreams. A responding body of water unmerciful at times, who records eternity with incrustations on rock, sifting and shifting to shape each grain of sand by rhythmic beats of her waves upon the shore. We exist above, seemingly beyond this boundary, never to sustain within. We tread upon that which surrounds her, aways taking heed to the intonations made by her voice as waves crash, then blend into the shore.
Life as the ship at sea shall always be set adrift. Searching to seek the calm and peace of the shore, only to once and again find ourselves out adhering to the pull of the tides. This pull for salvation shall set us free beyond safety of the perimeters set in motion of oppositions claim. To accept the flow, though it be against wish of the shore, is within our domain. These ventures are to guide us to our destiny. Intuituion and instinct speak without word, therein harmonizing our actions.
She feeds reflecting the energy of the sun and glow of the moon. She draws the clouds as the horizontal force of the winds deprive they blend. But as the rains begin their vertical descent, she opens gracefully accepting each drop. Continuous is the cycle of these matter and in them we find ourselves conjoined in basis of our likeness. Water is responsible as it never fails the simplistic rise of ascension through separation in gaseous exchange, only to descend and here once again join our hands in viscous motion, so that we too might now drift.
We find reason and therefore understanding of the things we do. In regard and neglect for all she gives and maintains, we are taking for granted with an ever assuming posture she is eternal.. We fail to realize we must give in return to maintain balance in nature. She knows our actions will reap her power and might, for it is through our salvation she takes back all that we failed to give.
Man’s carelessness, stripping and raping seeds of hers and our futures. Now in our pollution dense we see a saturating and weighing of the evaporatory release of energies vital, which mislaid shall sink this ship out to sea, never to find the shore and to submerge neath weight of our own doing.
The sea need not reason her actions, as thought does not find her place unaware. It is as it is. She seeks no harm nor vengeance, and justice comes of our thoughts demand. There is no right or wrong, as it is the way of things. For we do not gravitate in her tide. We find our pull amidst cranial chamber behind window of our eye.
As nature corrects the imbalance in the brain and the projection which has distorted our thoughts and vision blinding us, what comes into view finds man dying as mother earth and circulation in her streams gain the tide to reach out and touch healing that which sustains us. And should the solidity of matter prevent she seep into the place where stillness flows, she shall no longer gain way for strength to prolong that which she knows. Yet all the while purifying in mechansim to lift into the air weights which seem immovable. Her energies find obstruction in the barriers which our minds have taught our hands to build. Now our reasoning unknowingly negligent has construct in opposition her flow. A potential detached in borders which parallel insanity, and the link of unconscious thought owerwhelms behavior.
We take that to set as a potion, curious to cause as it once poured in unison and we form the substance to line our concrete jungles. It strangles all beneath, preventing the waters seepage and overflow to absorb in parched and hungry soil. Here again we find ourselves with misguided intent as the thought to precede purpose is caught unaware.
In time to pass ever so swift we find striking resemblance of our pain and disease mimicked in nature all around us and we wonder what went wrong with the intention of our creative thought. To each who live and are derived from substance alike, perchance cause can be extract from life not far extinct and we can then begin a renewal of our wrongs.
FOR SHE IS THAT VAST AND RESPONDING BODY OF WATER RECORDING AND ETCHING ETERNITY IN STONE, AS SHE SIFTS AND SHIFTS EACH GRAIN OF SAND WITH RHYTHMIC BEATS OF HER WAVES AS THEY CRASH UPON THE SHORE.
I speak of these waters created by this EARTH.
Earths time of change has come, so she uses her power to mend and heal all wounds. She melts the ice caps by speeding up the rotation of her iron core. This core shifts the electromagnetic fields that now hold us on a frequency not familiar with our place of origin. The evaporative nature of hydrogen builds to breach the barriers of the O3 layer or ozone. In so doing, the CO2 buildup in the atmosphere diminishes as Earth’s power breaks this bond to yield in conjunction with the aforementioned, the hydrogen carbonate (HCO3) which infuses the atmosphere recalibrating the ph. The end result is water. With more water in the atmosphere the variables such as refraction and gravitational constraints, which we consider normal , shall be no more. Time’s negative influence on man’s behavior will reverse in that of its opposition. There will be no choice in the matter. We shall adhere the dictation of which she speaks.
Her land mass has been seizing in energetic convulsive shakes preparing for the resurrection of matter. Her contained rest mass is being shattered by the silent infiltrating and unspoken diffusion of sufficient energy to recalibrate the ratios.
Everything we do and have done for millineum is in preparation for Earth’s resurrection. She will not die, and in so doing shall save all that lives on her surface. We cannot shift the tide, we cannot alter course of the flow, for it is she who speaks.
All our aggression, evil actions, self hatred, and warring mentality will cease to be. The light emit as Earth attains balance will fill mankind in the blink of an eye, and we shall all know that paradise existed right here all along.
We must temper ourselves…………dutifully awaiting the moment when from that center, the place of our true origin, all is equidistant to any and every where or when on the periphery.
Tis not founded in the laws of science, but in the law of nature. Here, everything unwinds naturally.

We were in New Zealand last year, where several glaciers that had been retreating 30 years ago have advanced significantly for the last 10.
All data that doesn’t fit the current orthodoxy is ignored:Antarctic temperatures have held steady or declined; northern hemisphere temperatures are declining again. Climate change happens all the time, we just don’t have any real idea what drives it.
I say follow the ice core data and THINK a little about the big picture. The Greenland and Antarctic data seem to correlate quite well, but Antarctica has several glacial cycles in its record but Greenland only one. In fact, the Greenland ice record only goes back to the beginning of the last cooling period. So, watch for instability in the Greenland ice sheet (which would occur after a long warming period – I think it is somehow involved as a trigger for the next cooling/ice age.
