Study projects big thaw for Antarctic sea ice

From the Virginia Institute of Marine Science and the department of unverifiable forecasts in our lifetime comes this model based projection.

Researchers say Ross Sea will reverse current trend, be largely ice free in summer by 2100

Antarctica’s Ross Sea is one of the few polar regions where summer sea-ice coverage has increased during the last few decades, bucking a global trend of drastic declines in summer sea ice across the Arctic Ocean and in two adjacent embayments of the Southern Ocean around Antarctica.

Now, a modeling study led by Professor Walker Smith of the Virginia Institute of Marine Science suggests that the Ross Sea’s recent observed increase in summer sea-ice cover is likely short-lived, with the area projected to lose more than half its summer sea ice by 2050 and more than three quarters by 2100. 

These changes, says Smith, will significantly impact marine life in what is one of the world’s most productive and unspoiled marine ecosystems, where rich blooms of phytoplankton feed krill, fish, and higher predators such as whales, penguins, and seals.

Smith, who has been conducting ship-based fieldwork in the Ross Sea since the 1980s, collaborated on the study with colleagues at Old Dominion University. Their paper, “The effects of changing winds and temperatures on the oceanography of the Ross Sea in the 21st century,” appears in the Feb. 26 issue of Geophysical Research Letters. Smith’s co-authors are Mike Dinniman, Eileen Hofmann, and John Klinck.

Smith says “The Ross Sea is critically important in regulating the production of Antarctica’s sea ice overall and is biologically very productive, which makes changes in its physical environment of global concern. Our study predicts that it will soon reverse its present trend and experience major drops in ice cover in summer, which, along with decreased mixing of the vertical column, will extend the season of phytoplankton growth. These changes will substantially alter the area’s pristine food web.”

Researchers attribute the observed increase in summertime sea ice in the Ross Sea—where the number of days with ice cover has grown by more two months over the past three decades—to a complex interplay of factors, including changes in wind speed, precipitation, salinity, ocean currents, and air and water temperature.

But global climate models agree that air temperatures in Antarctica will increase substantially in the coming decades, with corresponding changes in the speed and direction of winds and ocean currents. When Smith and his colleagues fed these global projections into a high-resolution computer model of air-sea-ice dynamics in the Ross Sea, they saw a drastic reduction in the extent and duration of summer sea ice.

The modeled summer sea ice concentrations decreased by 56% by 2050 and 78% by 2100. The ice-free season also grew much longer, with the mean day of retreat in 2100 occurring 11 days earlier and the advance occurring 16 days later than now.

Also changed was the duration and depth of the “shallow mixed layer,” the zone where most phytoplankton live. “Our model projects that the shallow mixed layer will persist for about a week longer in 2050, and almost three weeks longer in 2100 than now,” says Smith. “The depth of the shallow mixed layer will also decrease significantly, with its bottom 12% shallower in 2050, and 44% shallower in 2100 than now.”

The extent and duration of ice cover in the Ross Sea depends on a complex interplay of factors, including changes in wind speed, precipitation, salinity, ocean currents, and air and water temperature.

The extent and duration of ice cover in the Ross Sea depends on a complex interplay of factors, including changes in wind speed, precipitation, salinity, ocean currents, and air and water temperature.

For Smith, these changes in ice, atmosphere, and ocean dynamics portend major changes in the Antarctic food web. On the bright side, the decrease in ice cover will bring more light to surface waters, while a more persistent and shallower mixed layer will concentrate phytoplankton and nutrients in this sunlit zone. These changes will combine to encourage phytoplankton growth, particularly for single-celled organisms called diatoms, with ripples of added energy potentially moving up the food web.

But, Smith warns, the drop in ice cover will negatively affect several other important species that are ice-dependent, including crystal krill and Antarctic silverfish. A decrease in krill would be particularly troublesome, as these are the major food source for the Ross Sea’s top predators—minke whales, Adélie and Emperor penguins, and crabeater seals.

Overall, says Smith, “our results suggest that phytoplankton production will increase and become more diatomaceous. Other components of the Ross Sea food web will likely be severely disrupted, creating significant but unpredictable impacts on the ocean’s most pristine ecosystem.”

The authors use historical temperatures and winds to verify their model. They then accept projected temperature increases of about 1.66 and 2.5 degrees C through 2050 and 2100 respectively to make their projections.
So the model may be quite reasonable, but its forecasts depend entirely on the assumed increases in Antarctic temperatures and wind shifts. Those changes remain entirely absent thus far.

The arctic, which is demonstrably reducing in extent over the record, shows no significant change in the melt season. I show the date of maximum ice in the arctic is coming earlier by 4.5 days per century, but this is offset by the summer minimum also coming earlier by 4.0 days per century. The total melt season is only increasing 0.5 days per century.
Yet this study of the Ross Sea suggests an increase in the melt season by nearly a month?
I pray that “booster spice” is found soon, so these idiots are alive when the predictions are falsified.

The supplemental material notes that the 2046-2050 temperature increase is 1.66C plus or minus 2.58. So if there is cooling over the next 40 years, he’s still spot on. I wonder if he’d be open to a decadal bet; run the model for the endpoint delta T’s at 10, 20, 30 and 40 years based on the central values. I’ll kick in $50 per decade to see if he hits his marks. Think he’ll take me up on it?

The first IPCC report projected a decrease in Antarctica sea ice. Their last report acknowledged an increasing trend since 1979. They admit in the same last report that they don’t know why but still ‘project’ a decrease this century. They also project an increase in snowfall up to 2100.

Now, a modeling study led by Professor Walker Smith…
climate models agree that air temperatures in Antarctica will increase…
Smith and his colleagues fed these global projections into a high-resolution computer model
The modeled summer sea ice concentrations decreased…
Our model projects that the shallow mixed layer will persist for …

Of the 1.66 °C till 2050 we still miss 1.66 after almost 1/3 of the time in this century even with all the innovative adjustments for urban cooling.
This “urban cooling” phenomenon is one of the big recent discoveries of the CAGW science.
http://oprj.net/articles/climate-science/31
NASA GISS are currently the only group calculating global temperature estimates that explicitly adjust their weather station data for urbanization biases. In this study, their urbanization adjustment procedure was considered.
A number of serious problems were found with their urbanization adjustments: 1.) The vast majority of their adjustments involved correcting for “urban cooling”, whereas urbanization bias is predominantly a warming bias. “

February 27, 2014 3:38 pm

I might be able to make it to 2050. If so, I will remember this 56% reduction claim and be there to remind them of it.

February 27, 2014 3:40 pm

Their prediction “modeled summer sea ice concentrations decreased by 56% by 2050” will certainly make the “climate fail” category . The growing Antarctic sea ice is aligned with the lack of warming at the south pole and the increasing ice mass in east Antarctica, as well as declining solar activity. Antarctica’s Ross Sea ice will indeed vary with El Nino/La Ninas and their effect on the Aleutian Low, but the long term trend will continue upward as solar activity continues to wane. Antarctic sea ice is a better indicator of global climate change. Natural cycles will cause Arctic sea ice to recover while Antarctic sea ice will continue to expand. http://landscapesandcycles.net/antarctic-sea-ice–climate-change-indicator.html

Dear Dr. Walker,
I have an important question for you, which I hope you can answer.
How long ago was it that summer sea ice cover in the Ross Sea was
last at the level your modelling attempts predict it to be by 2100?
Oh, yes, and here’s a bonus question:
And where on the planet was the landmass we now call Antarctica
located when this low sea ice event occurred?
Thank you.

February 27, 2014 4:01 pm

Antarctica’s Ross Sea is one of the few polar regions where summer sea-ice coverage has increased during the last few decades, bucking a global trend of drastic declines in summer sea ice across the Arctic Ocean…
OK, first, unless you define ‘few’ as ‘all but one’, the first statment is obviously false. Then, it appears that he is mixxing up Arctic and Antarctic. The Arctic Ocean is in the North (near Canada and Russia), while Ross Sea is in the so called Antarctic Ociean (bits of each ocean surounding Antarctica) is in the South. Some ice reduction in the North (unrelated to this study), but almost all increased ice in the South.

If I predicted a coin toss of heads 100 times in a row, I will eventually be proved correct. However, I may have to toss that coin once a second for several thousand years.
I reminds me of a version of the old saw of 10,000 monkies on 10,000 typewriters eventually producing a Shakespearian play:
If I had a computer which had a display and every second, it produced a new image, simply in black and white, every second, after some time it would produce the Mona Lisa image.
True, theoretically. Assuming the machine can survive that long. Let’s do the math:
For a black and white image, i.e. binary image, no gray scales, of say around 700 x 500 pixels – that is 350,000 pixels, definitely not HD, there are 2 to the power of 350,000 combinations. That is a number of seconds much larger than there is in the Universe; and certainly beyond the MTBF of the computer itself.
Therefore, I suggest that 10,000 monkies on 10,000 typewriters cannot produce a Shakespearian play. Either the monkies will die or the typewrites cease to function.
Therefore, I say that you Warmistas should just give up, game over. You can continue to predict death and disaster (D & D), and you will always be successful in your predictions because D&D is the lot of humanity. However, your prediction of D&D is meaningless.

“Gravy train science.”
That says it all, in just three words.
My own model predicts that any ice loss in Antarctica will be fully offset by ice gain in the Arctic. That has always been the case in the past with the polar see-saw, as far as reliable records go.
I am a big believer in the Null Hypothesis. Nothing happening now is either unusual or unprecedented. And any changes are likely to be toward a cooling planet, as this long term Holocene chart indicates.
But of course I won’t be getting any grants for pointing out the obvious direction of the climate based on past indications. To get my ticket punched on the gravy train I would have to do a Chicken Little imitation, and sound a false alarm that the sky is falling.

Heh. Given the long term increase in global sea ice, the areas must be pretty tightly constrained to make this statement true. “We only have TWO areas where sea ice is increasing! Certainly, we only created an arbitrary group of three so we could make this statement, but 2 is a small number (over 66% smaller than 3 if you study it closely) so we feel justified in saying that it’s one of the few.”

Hmmmmn.
Just one area was increasing, eh? Which Antarctic continent is he looking at, this supposed climate scientist “expert”?
The ANOMALY last year for the Antarctic sea ice extents AVERAGED just at 1.0 Million square kilometers all of last year … In October 2013, the antarctic sea ice extents anomaly – the difference between measured sea ice and the normal sea ice extents was larger than 1.4 Mkm^2. And it was remarkably steady through the entire year. This increase in day-to-day-to-day Antarctic sea ice extents was about 1/3 the entire area of Greenland! And at the same latitude as the middle of Greenland too.
In fact, the ENTIRE Antarctic sea ice extents has been increasing through EVERY season of the ice year since May 2011. Almost three years now the Antarctic sea ice has been increasing, on a pace to soon block the Cape Horn sea route in 8-10 years.
The entire area of Hudson Bay is right at 1.2 Mkm^2.
So, the POSITIVE ANOMALY of Antarctic sea ice extents for the entire year was larger than Hudson Bay, and as mentioned above, a substantial fraction of the entire area of Greenland.
Now, if “one bay” near Antarctica sheds “one” large iceberg, we re told everything is melting and doom will ensue! If in 96 years ONE bay near Antarctica “might” lose “some sea ice” and this “expert” gets written up as if he had discovered a new miracle.
But, just let the Antarctic sea ice extents increase by an area equal to the entire size of Hudson Bay, and does this “expert” even notice?

“My study predicts that there will be little to no significant change in the current trend while experiencing minor fluctuations in ice cover in summer involving varying time scales. Additional
fluctuations in the mixing of the vertical column will result in ebb and flow changes to the season of phytoplankton growth. These ongoing changes will preserve the area’s pristine food web.”

The Magellan Striate is close to freezing enough to block passage. Major shipping companies worldwide are worried about this because even the expanded Panama Canal cannot accommodate the giant container ships now sailing. This tutti fruity is worried about the Ross Sea where the likelihood of melting is slim and none and slim is on a gurney to the morgue. I guess we have to keep up with the enemy but reading this junk gets tiresome.

Same crap, different decade. 25 years ago when I bought into this nonsense they were saying by 2010 Antarctic would be red hot and there was going to be a runaway “greenhouse” effect (comparing it to a real greenhouse).
Nothing they say holds one iota of credibility. They just make it up as they go along. Frankly I’m sick of the whole affair.

Sorry to say, but James Hansen’s Congressional testimony and the below article in Popular Science (how could NASA scientists be wrong?) made me a True Believer for about 15 years, then I discovered Steve McIntyre’s original website (forget the name now), and began asking questions as he was banned from RC for simply asking questions. I thought it was odd that they would ban someone for asking for data. Prior to the internet we only had the MSM and the talking heads on network news. Who was I to doubt them and the climate scientists they hand picked to present the “truth”? Within a year it became clear there was much dishonesty, exaggeration and downright lying going on. I waited for the predictions to occur, but they didn’t happen, particularly the vaunted “greenhouse” effect.

Duh, where did they not predict substantial warming of air temperatures in coming decades?
However, I suspect they may be right about the ice. What they neglect is the corollary that the Arctic sea ice will increase proportionately.

Of course it will decrease in size , the only alternative is that it will keep growing until it takes over the world or stays the same. Sounds like the only option is that it shrinks until it grows again.

Every one talks about the heating effect of sun on the polar seas. Nobody mentions the properties of sea water during the polar winter. Ice has high albedo! How effective is this during the polar winter? The ice surface can cool to many degrees BELOW zero Celsius. Radiative cooling effect of ice is low. Sea water on the other hand will freeze and turn to ice at around -2C only if left in peace. On the other hand if the sea water is churned up by wind storms the sea surface temperature can reach several degrees ABOVE zero. Use the S-B formula to calculate the radiative energy leaving say a million square kilometres of sea surface at say 275K as opposed to that amount of ice surface at 258K over a period of about four months during the polar winter. This energy is leaving from the SEA. I think you will find it accounts for the ‘missing heat’.

Sarah

How is it that the alarmist scientists can find no possible natural explanation for any warming and ergo the warming must be nearly all man made, but they have absolutely no difficulty finding hundreds of natural causes for cooling which counteracts this amazingly mysterious warming.

“But It’s turtles…. ALLLLLLL the ways down…
The turtle story is cute, but when “scientists” basically replace turtles with models, it’s get’s a bit tedious; especially since my taxes help pay for that vile tasting turtle soup…
The Antarctic Ice Extent looks to have just hit its annual minimum yesterday, and still stands at about 2 standard deviations (+620,000 KM^2) above the 34-yr mean…
It’ll be interesting to see what new turtle CAGW acolytes come up with to explain this year’s record-high minimum Antarctic ice extent.
On a somewhat related topic, I noticed an interesting phenomenon this year in the Arctic. When record breaking cold air swept down from the Arctic to cover huge portions of the US, DMI Arctic anomalies spiked up +15C at the same time. Accordingly, with the warmer than normal Arctic temps this winter, less Arctic Sea Ice formed this winter.
When the Arctic Sea Ice starts to melt, I expect the Arctic Sea Ice anomaly to be quite large this year. The warmunistas will, of course, blame the smaller than normal Arctic Sea Ice Extent on Global Warming and conveniently forget about the bitter cold in the US, which at least contributed to the lower than normal Arctic ice formation.

Back in the 90’s Global Warmists gave safe 70 to 80 year projections, gaining confidence they reduced the timeframe to 30 to 50 years, once the governments climbed on board, money started flowing and the arrogance grew the projection timeframe began falling rapidly to the short term which unfortunately could be checked. After the disasterous forecasts of the last decade they have now started to expand their forecasts to the long term again. Can’t be checked.

I realize that the population didn’t die off, England is still here, people there aren’t starving, India is, in fact, doing quite well…BUTTTTTTT….THIS time, I used other models, which have always been wrong, to figure out the amount of warming involved, which they’ve never been able to do, and used that as input to my own untested and unproven model, and it clearly shows that we’re all in dire straights. Oh…and I’ll need some more money to refine things a bit more.”

I agree with both the above comments and,according to a bit of analysis I’ve done on the Cryosphere numbers, the mean date for Antarctic sea ice extent is 25 February. Having said that, I would counsel caution. At either pole and at minimum or maximum extents, the measurements do often fluctuate for some time before any definitive trait becomes apparent.

“If it disagrees with experiment (i.e. reality), it’s WRONG. In that simple statement is the key to science. It doesn’t make any difference how beautiful your guess (model) is, it doesn’t matter how smart you are who made the guess, or what his name is… If it disagrees with experiment, it’s wrong. That’s all there is to it.” – Richard Feynman
“…global climate models agree that air temperatures in Antarctica will increase substantially in the coming decades, with corresponding changes in the speed and direction of winds and ocean currents. When Smith and his colleagues fed these global projections into a high-resolution computer model of air-sea-ice dynamics in the Ross Sea, they saw a drastic reduction in the extent and duration of summer sea ice.”
The only thing this study proves conclusively is that the authors are not scientists. No real scientist would use falsified model projections as input for a subsequent model. Ray (in comment #1) nails it.

The faith that too researchers put into models which have demonstrated no ability to model what they claim they are designed for is fascinating.
The money wasted on studies like this, based on the failed modeling system is annoying.
The transparent attempt to distract from the Arctic, the growing list of failed AGW predictions and to offer yet another target fro fear and hype is quite cynical.
That they seem to claim it is air temperatures and not ocean currents that do most of the melting of pack ice raises questions as to if the authors are even serious.

The Antarctic ice cover has been increasing for 30 years, yet it has had no adverse or substantial effect on flora and fauna. However, all of a sudden, a predicted reduction in ice cover will have a massive adverse effect on said flora and fauna. I smell yet another rat in really poor grade school writing.
Similarly if the UK became covered in ice, it would not require much cenc to state that such an event woud have an adverse effect on cows and sheep living in the UK.

Give him his due. He hasn’t been so stupid as to actually go there. People who do that are liable to get trapped by non-existent ice. At least he stayed warm and at home, where he ran absolutely no risk of his prediction being even a little wrong.

Researchers attribute the observed increase in summertime sea ice in the Ross Sea—where the number of days with ice cover has grown by more two months over the past three decades—to a complex interplay of factors, blah, blah-blah, and blahbitty blah blah. In other words, coincidence.

The Polar See-Saw
Headline Grabbing Climate Scientists are being fundamentally dishonest when they ignore the Polar See-Saw. They know full well that today’s observations of a warming Arctic and cooling Antarctic are completely consistent with natural variability going back tens of thousands of years.
The timescale of the Polar See-Saw matches the natural 1000-1500 year climate cycle observed by many researchers.
Modelling the bipolar seesaw
North Atlantic temperature changes are mirrored by equal amplitude South Atlantic changes of opposite sign.
http://www.iceandclimate.nbi.ku.dk/research/climatechange/modelling_dynamics/bipolar_seesaw/
Applying the model to the data of GRIP and Byrd, we demonstrate that maximum correlation can be obtained using a timescale of about 1000-1500 years.

I remember a ‘prediction’, based on models, that the Arctic would be ice free by 2013 – didn’t happen. We have seen that 95% of GCMs have been wrong about the projected increases in temperature, therefore I can say, with a 95% confidence level, that this ‘prediction’ is also wrong.
As an aside, for over 30 years I worked in the real world with engines which were projected, by the engineers who designed them, to work at efficiencies which they were theoretically capable of achieving. Never did I see one work at its theoretical limit. In my experience, the models used are designed to project the best, or worst, case scenario, and when they are applied to the real world they are almost always overly optimistic, in the best case, or overly pessimistic, in the worst case.

Their Abstract states:
“…We examined the effects of projected changes in atmospheric temperatures and winds on aspects of the ocean circulation likely important to primary production using a high-resolution sea ice–ocean–ice shelf model of the Ross Sea.” [my emphasis]
In other words: “We assume that forecasts made from unproven models are correct; we extract the results that we think are most useful for our hypothesis and then we use them as input into another untested model – one which is based entirely on unproven conjectures.”

I think we can safely predict that, computer technology in the near future will be much more advanced than it is now. So, ten years from now, we will look back at todays computers with much the same view we have now of ten year old computers. Things have improved a lot in the technology world in a relatively short space of time.
However, even though we can see huge errors and failures with past climate model predictions, they seem to be stuck in a time warp. Still intent on making the big warming predictions, despite having missed the big current pause, it looks like the only thing their models are capable of predicting, is warming regardless. In fact, you don’t need models to make these predictions into the future, just a wild guess with a large dose of bias.
Unfortunately, they don’t have to be right, they just have to get the scare out there. For a lot of people, this is good enough to convince them that this disaster, headed our way in 2050 and even worse again another 50 years after that, is a reality. No chance that they are wrong.
