Sea Ice News #29

In sea ice news this week, Arctic sea ice continues its inexorable climb toward the summit, to be reached sometime in March 2011. At present the ice growth is tracking just below the rate of 2007, but it should also be pointed out that according to JAXA’s AMSRE plot, we are still slightly ahead of this date last year.

The magnified view below shows just how close together all the past years are in the “choke point”:

2010 is just between 2007 and 2009 at present, and all three traces have a “knee bend” at this point, though 2010 is sharper.

Current data for JAXA:

10,31,2010,8075000

11,01,2010,8240938

11,02,2010,8403594

11,03,2010,8500000

11,04,2010,8621875

11,05,2010,8672500

11,06,2010,8693438

11,07,2010,8800781

11,08,2010,8908906

11,09,2010,8987031

11,10,2010,9056406

11,11,2010,9117656

11,12,2010,9164375

11,13,2010,9172969

11,14,2010,9183594

Over 1 million square kilometers of sea ice extent has been added in the past 15 days.

NSIDC’s plot shows 2010 compared to 2007, but has 5 day smoothing, so the knee bend is not visible.

But the NANSEN plot shows these bends clearly:

Overall, nearly the entire Arctic ocean is well filled with sea ice at this point. Only the Barents and Chukchi seas have ice free areas:

Temperature within 80°N is slightly below normal at present, thought= nothing out of the ordinary variance:

Antarctic sea ice extent remains above normal:

I’ve posted on this before, but I now have something to back up my comments about Chinese pollution.
When China has power shortages, as it did in 2004, its factories used diesel generators, which allowed them to continue functioning, but created a lot of pollution. I saw this first hand in Hong Kong: the air simply became very bad.
The Hong Kong Observatory publishes “Number of hours of Reduced Visibility” here:
http://www.hko.gov.hk/cis/statistic/hko_redvis_statistic_e.htm
You can see how dramatically polluted the air became from about 2002 onwards, and that it got (slightly) better by 2008. This coincides quite neatly with the Arctic ice lows.

This focus on one particular pole’s ice extent does the skeptic’s position no good imo. I have been following your ice posts for a long while and all I can say is…. what’s up with that?
You are focusing on weather, for god’s sake. It makes no difference about sea ice extent. This is what THEY want us to think. Once the Arctic ice is gone, we are doomed to an irreversible tipping point which will plunge us all into an eternal hellfire. So this is why you are focusing on it – to rebut THEIR assertions. But I am convinced this tact will come back to bite you. Artic ice is simply weather. Maybe over a decade or two. It has little to do with global climate trends.

I agree with Mike Jowsey November 15 at 12.14am that we should have a wider regular update of key indicaters rather than just sea ice (with emphasis on Arctic). I posted yesterday on Tips & Notes
“I would recommend an article about “Have we arrived at at Tipping Point?” and if so which one? Atmospheric temperatures have remained steady since 1998 and may even be reducing slightly. Global sea levels are going down now. Arctic and Antarctic sea ice extent are within natural variability. Argo will not release ocean temperatures. (Suspicious and assumed to be because they are declining now) That would fit in with declining sea levels. These are all major indicators showing that the globe’s heat budget is not going up. Maybe we are at a tipping point but not as the AGW supporters think. There are clearly other forcings out there overwhelming CO2 (or negative feedbacks) as CO2 has been going up steadily by around 1.5ppm/year when the climate has steadied temperature wise. I think that a great article could be composed drawing together the implications of what major indicators show at present. This could be compared with models to show how wrong they are. Something hard hitting based on recorded facts.”
We should have global atmospheric and sea temperatures, Sea ice N/S, and sea levels To me these are major indicators of where we are heading. As far as I can see we are not at present “racing” towards this socalled “Tipping Point” when temperatures run amok. It seems to me that we are at at 50/50 point where it is as likely we are heading down as up.

Climate does not have tipping points. It changes but all changes are reversible due to natural cycles.
Temperatures have been higher and lower than those of today. Atmospheric CO2 content has certainly been much higher than today, in fact present day CO2 atmospheric content should be higher if you want plants to grow more and produce more food.

I notice that ‘ice cover’ is defined as at least 15% ice. But this means that some areas are 85% open water. Is there any data as to how actual ice, as opposed to water, there is, and how this compares to previous years?

November 15, 2010 4:14 am

I agree with Mike Jowsey that focussing on the Northern polar regions is assisting the Warmists make quick, if spurious points. I would enoy seeing a presentation of Arctic V Antarctic ice growth and retreat and other comparative information to provide a more balanced narrative about ice events on a global scale.
I feel a little greedy making this request, as what we are presented with at WUWT is indeed great, but in a very few cases I feel that more may really be better.

While we all would like a ‘clear’ picture of a lot of things I believe care must be applied to Arctic vs Antarctic comparisons. Which leads, which follows? We don’t know. Then the dynamics involved for each (in regards to sea ice) are different. What winds, currents, and the AO are doing to affect the Arctic will not be relevant to what is going on in the Antarctic.
The “Global Sea Ice” graph on the actual Sea Ice Page

Combined with the data for the individual hemispheres gives about as clear overview of sea ice status as one could hope for.

What you say is possibly correct, but I’m not sure that you have understood exactly what Anthony is doing, and why. What I see is that Anthony has set up a couple of pages giving objective data on sea ice, sea temperatures and sea levels. Scare-mongering about these is one of the alarmists’ tactics, and simply presenting objective data is an effective way of countering scare-mongering. This data is sourced from reputable third parties, and is untouched by WUWT. Data for both poles is in fact provided, though the Arctic has tended to get most of the attention. Anthony also provides a specific post from time to time, such as this one, but IMHO the main thrust is via the now permanent objective data pages.
You may be absolutely correct in saying that sea ice has little to do with global climate trends, and there are a number of papers showing that winds and currents are the major influences on sea ice in the shorter term. However, there is evidence, which has been posted at WUWT, that Arctic ice increased in previous cold periods and decreased during previous warm periods. This suggests that sea ice is indeed affected by temperature. It doesn’t really matter much what the major influences are, the important thing is to make genuine data readily available so that it becomes more difficult to misrepresent what is happening. If you are correct in saying that sea ice has little to do with global climate trends, then the data will eventually show just that. (And BTW, if the skeptics are wrong and the alarm is well-founded, then the data will eventually show that instead).
I hope you can agree that if genuine data is made readily available, then it becomes more difficult for either “we” or “they” to misrepresent the situation.

I don’t know why people measure at the extremes any way.
The extremes, March and September, can be affected by too many things
that have nothing to do with nothing. That’s where Ice is at it’s most unstable,
and even the slightest change in wind or cloud cover can make a huge difference.
It always seems to come back together at the “choke points”, May and December,
and that’s where people should really look.

Hi,
I think that the NSIDC data can’t be trusted, I explain you why.
Their graph shows ice in the southernmost part of the St. Lawrence gulf. I strongly doubt that all that ice is present in the St. Lawrence gulf this time of the year…

November 15, 2010 8:19 am

Question: if “nearly the entire Arctic ocean is well filled with sea ice”, why is the ice extent roughly one million sq km (9%) less than the 1979-2006 monthly average (per NANSEN)? And why is the ice extent roughly 5 million sq km (1/3) less than the March peak extents?
Does the ice extend far outside the Artic Ocen at its peak? If so, what is the significance of the ocean being filled (other than frustrating people starting polar shipping lines)?

AJB
November 15, 2010 8:43 am

Closest to the fill rate pattern of 2004 so far, geography seems to be the upper constraint in all this. Anyone know of any monitoring of the heat coming from these things and how that’s varied over the years?
http://www.nsf.gov/pubs/2005/nsf0539/nsf0539_13.pdf
Seems to at least affect the Chukchi freeze-over, watch the DMI SST anomoly loop at http://ocean.dmi.dk/arctic/satellite/index.uk.php. Since this heat feeds directly into the Gyre, how big a variation does it take to eventually affect the annual cycle and minimum extent numbers?

dp
November 15, 2010 8:51 am

This is the time of year when the rate of ice coverage change varies little from year to year. The larger changes is what day of the year this particular volume is achieved. Missing from all this is what day is the correct day for this volume of ice to have formed. And of course we don’t know. We have only the averages from 1979 to present and that is a blink in the time frame over which our interglacial cycle has existed.
In fact, though, this volume of ice is reached within days of the day for every other year, and the rate of change is always rather close on a seasonal basis. Why is this a talking point? It seems meaningless unless we see a trend where ice coverage volume on this date is consistently occurring ever earlier or later in the year. That is just not happening, and it won’t even be an important chart for at least a hundred years anyway.

I think one improvement that could be made to the ice analysis is to have all of the daily data points on every published graph made available immediately to the public. I believe that one of the reasons that the AMRS-E data is watched so closely is that the data points are released every day. This facilitates analysis and it also makes it relatively more likely that errors in data collection will be quickly detected by someone and reported back to the source of the data.
WUWT could do a service by continually pressuring agencies for the release of such data (something that is already being done to an extent, but perhaps the pressure could be much greater if an effort were made to enlist others in the effort, including sympathetic legislators. If an agency is disseminating only a graph with a five-day average, errors can persist for days, weeks, months or even forever because it’s too difficult to convert the graph to data points, sort out the averaging, etc. One person could do it but it takes too long to make the point to others and so the errors persist. (Or the obfuscation, if you’re the suspicious type.)
Another benefit of agencies releasing daily data points is that discrepancies between agencies would become more obvious. Some would have logical explanations such as one being 30% extent, the other 15%, etc., but some would claim to be measuring the same thing but coming up with significantly different results for extended periods of time. If the daily data is available, people will start digging for explanations of the discrepancies and the data collection/reporting effort will be likely to improve (much as Anthony’s SurfaceStation project is putting pressure on to improve land-based temperature collection.)
It’s my understanding that tax dollars are financing almost all of the data collection efforts. It’s a reasonable request that the daily data points of the publicized graphs be made readily available and easily accessible.

Exactly, weather not climate. The more I follow this along, the more “Arctic” sea ice extent/area seems like a big chocolate pipe wrench being used as a micrometer – nonsense not science.
Measuring the annual latent heat exchanges taking place might tell us something but none of this navel gazing gives us the slightest clue about that IMO. It just serves as fodder for yet more cringe worthy AGW propaganda.

_______
Of course Mike, over the past 3 decades (and even longer) Arctic Sea Ice has been steadily going down down down. Sceptics made much of a “recovery” in 2008-2009, which is within the bounds of normal variation. But 3+ decades of decline and thinning of Arctic Sea Ice IS climate and not weather. True, Anthony and others blow by blow account of the state of sea ice is weather, but as soon as something doesn’t fit in the the sceptical paradigm (like last spring, when Arctic Sea Ice almost got back to normal) you know they must make the most of it.
As it stand, the state of the Arctic is the best indicator of the general state of the climate, but that “state” must be looked at over the longest time-frame in which we have reliable data, which is just over 30 years. Now it may be conincidental that during the entire period we have reliable satellite data on the sea ice that it has been during a declining period and is not indicative of a longer term CO2 induced climate change. But I tend to not like such coincidences, especially when they coincide with other predicted changes from AGW.

We have had this conversation before, but it is simply not true to say we only have reliable records of arctic ice for 30 years. The arctic has been a well travelled and observed region for hundreds of years. My own home town was sending whalers to the region over 350 years ago. I don’t know why you consider satellite records to be so reliable, for example they are unable to properly differentiate between open water and water lying on top of ice.
As regards earlier periods of warming please note these two articles which are on my web site;
http://climatereason.com/LittleIceAgeThermometers/
“Article: The Great Arctic warming in the 19th Century. Author: Tony Brown
This long article -with many links- examines the little known period 1815-60 when the Arctic ice melted and the Royal Society mounted an expedition to investigate the causes.”
http://wattsupwiththat.com/2009/06/20/historic-variation-in-arctic-ice/#more-8688
Plus this:
“Article: Arctic warming 1919-1939. Author: Dr Arnd Bernaerts
I have often written short pieces on the frequent episodes of Arctic warming back to the Ipiatuk some 3000 years ago, and one day will work them up into a longer piece. This free online book by Dr Arnd Bernaerts examines the last great warming -prior to the modern one- in great detail.”
http://www.arctic-heats-up.com/chapter_1.html
I have gathered together the material for my Parts 2 and 3 of ‘Historic variations in sea ice.” There are dozens of episodes of considerable long tern melting of the ice.

R. Gates says:
“…3+ decades of decline and thinning of Arctic Sea Ice IS climate and not weather.”
Wrong. The Arctic is not the globe, it is a region. For example, Antarctic ice cover recently hit a 30-year high. They are neither global climate nor weather; they are examples of always-changing regional variability. Only alarmists believe that the climate never changed prior to the invention of the SUV.
Gates continues:
“As it stand, the state of the Arctic is the best indicator of the general state of the climate…”
Wrong again. Even a broken clock is right twice a day. The reason for all the frantic arm-waving over the Arctic by the alarmist contingent is because that is the only thing that they can point to that might support their crazy world view. Their models are wrong, their predictions are wrong, and their assumptions are wrong — but hey, the Arctic region has fluctuated in a way that could be imagined as supporting their lunatic CAGW argument, so they grasp that lone example like a drowning man grabs at a straw.

Could it be possible that the “choking points” are at least as interesting to measure and compare, from a scientific point of view, than max/min ice extent?
A big deviation there would indicate a fundamental change in how the climate system works?
Or does it represent the same mechanism, only less magnified?

Sealevel graph broached the 20mm level in 2003; broached the 30mm level in 2006 and it is about to broach the 20mm level again, this time coming down. There is a decided flattening of the curve – we should do a polynomial fit too.

To Tony B.,
I respect your research very much and it is this kind of anecdotal evidence for past warmings that do keep me partially in the AGW sceptics camp, but I think the current warming of the Arctic has not happened since at least the Holocene Optimum. I do not believe that the warming earlier in the 20th Century was on the same scale as now. I do believe there is a higher probability than not that the 40% rise in CO2 since the 1700’s is playing a role in the current warming of the Arctic, melting of Greenland, etc. I think those who would completely deny this possibility are being blind to the science. However, I am not a “catastrophic” believer in AGW, as it just could be that a warmer world (induced by CO2) will play out for the better in the long run for life, but I certainly wouldn’t bank on it…

Re the “knee bend”, isn’t that the flip side of the old knee bend on June 1 from the change in algo to reflect the puddle problem? I believe somewhere in November (1st? 15th?) they change back, causing a similar phenomenon, tho for whatever reason not as markedly pronounced as the spring one.
I believe they tried to smooth that out in the Spring this year. Don’t know if they bothered to do the same in the Fall. . .

I find it hard to believe that the 1979-2006 +/- 1SD is in fact part of the same data-set.
The last four years show a much greater amount of variation than would be supported by such a small SD. It would be nice to do a rolling n=7 mean, starting at 1979 (centered on 1983) and see what the plot of SD (n=7) is between 1983 and 2006.

Cryosat 2 is calibrated and due to provide data soon about the real issue; ice volume.
Halelujah, the ice cube will be proven an ice slice. There is nothing odd about the ‘choke point’, when the sea ice reaches land boundaries, the ice growth slows, limited by the Bering Strait to the Pacific and the Greenland Sea to the Atlantic. Maximum sea ice extent still decreases 3.4% per decade and Minimum extent 11.5% per decade. Ice volume (multi year ice) has decreased dramatically. This does not bode well for the next melt season, when there is much more one year ice to melt. Each summer more ocean is exposed collecting heat. Over the next decade we will see melt seasons become longer and freeze seasons shorted. The process is now unstoppable. As expected by scientists the sea ice extent recovered from the exceptionally low 2007 extent (-1.5 million sq km) It recovered one third (.5 million sq km) in 2008 and a similar amount in 2009. 2010 refused to oblige, so the ‘recovery’ is still 500,000 sq km short. If the next melt season combines with an El Nino, may well see the 2007 minimum surpassed. The presen La Nina is now (as expected) decaying, the SOI has dropped from +25 to +15. The ‘choke point’ reading on the graphs is irrelevant but expect the choke point to occur at increasingly lower sea ice extent levels.

Wrong. The Arctic is not the globe, it is a region. For example, Antarctic ice cover recently hit a 30-year high
—–
Wrong. It (antarctic) was below the 30 yr average from Jan. 2010 to May 2010. It was slightly above the 30 yr average from June to September 2010. Then fell to and below the 30 yr average between Sept. and Nov 2010. The arctic and antarctic are literally poles apart, different dynamics. Not tit-for-tat ice comparison, I have less ice but you have more. Antarctic sea ice grows in winter and melts in summer, no landmass boundaries. No thick multi-year ice, like the arctic used to have but is losing rapidly.

A clock maybe, a false argument remains, false. Why are models, predictions and assumptions invariably wrong when supporting global warming and always right when it supports no-warming or behold, cooling. Do models have one-way trustworthiness?

R Gates : “the state of the Arctic is the best indicator of the general state of the climate
Why the Arctic? Surely the Antarctic, which is bigger, is better. Particularly as it is surrounded by oceans, so (a) ice extent is not limited by nearby land masses, (b) it is generally agreed that ocean heat is a better indicator of global warmth than atmospheric heat. CO2 measurements at the S Pole are in line with the rest of the world, so there is no suggestion that it is isolated from AGW.
http://members.westnet.com.au/jonas1/CO2AtVariousStations.JPG
R Gates : “I do not believe that the warming earlier in the 20th Century was on the same scale as now
You may be right, but is that significant? Please note that these temperatures closely match the ocean oscillations:
http://wattsupwiththat.com/2010/09/30/amopdo-temperature-variation-one-graph-says-it-all/
R Gates : “. I do believe .. that the 40% rise in CO2 .. is playing a role… I think those who would completely deny this possibility are being blind to the science.
My reading of WUWT, and of climate skeptics’ statements in general, is that not only is this possibility not usually denied, but it is mostly specifically accepted. But how important is this role of CO2? The main argument is that the role of CO2 and its predicted impacts on the planet have been grossly exaggerated, and that the “scientific” arguments put forward have been woefully unscientific.

______
There are numerous very good scientific reasons why the Arctic, more than the Antarctic has long been predicted to show the first and most extreme effects from global warming. Not that Antarctica is immune, and will not, over time show effects, but GCM’s have long projected the earliest and most extreme changes would be seen in the Arctic. These projections were made long before the extreme summer low of 2007, and in fact, that kind of low was not suppose to occur until 2020 or so, based on the GCM’s. But that is another story entirely, and gets into the whole issue of chaos theory and the unpredictability of systems that are at the edge of chaos, and specifically the unpredictability of positive feedback processes involved in such systems…and this gets back to the reasons why the Arctic is a better and stronger early indicator of a warming planet than the Antarctic…it is precisely because the Arctic is an ocean surrounded by land and warming in one can be amplified and lead to warming in the other. In the Antarctic, the surrounding ocean serves to buffer the warming as it serves as a much better heat sink than the land surrounding the Arctic.

Let’s keep this simple, a la Ocham’s razor. The GCMs were wrong, yet again. Given the remarkable fit between temperatures and ocean oscillations,
http://wattsupwiththat.com/2010/09/30/amopdo-temperature-variation-one-graph-says-it-all/
it is most likely that the decline in Arctic sea-ice in the late 20thC (including 2007) had little to do with AGW but was caused by ocean oscillations (and hence ocean temperatures), winds and currents.
The IPCC report (SfPM) says “Sea ice is projected to shrink in both the Arctic and Antarctic under all SRES scenarios.“. But the Antarctic sea ice has been static or increasing for – how many years now?
I note that you made no reply to my last point : “My reading of WUWT, and of climate skeptics’ statements in general, is that not only is this possibility [that CO2 plays a role] not usually denied, but it is mostly specifically accepted. But how important is this role of CO2? The main argument is that the role of CO2 and its predicted impacts on the planet have been grossly exaggerated, and that the “scientific” arguments put forward have been woefully unscientific.“. If I have misrepresented WUWT or climate skeptics, then I trust that someone will step forward and correct me.

Hallelujah indeed! You really were in the zone, or in the spirit, to produce this extatic stream of AGW Arctic prophecy.
A few factual problems however. You state: “Each summer more ocean is exposed collecting heat.” This is the exact opposite of the case around the Arctic. Here exposed water loses rather than gains heat. This summer for instance the combination of above average sea temperatures (linked to the AMO) and well below average air temperatures resulted in greatly increased loss of heat from Arctic seawater. This fits into a pattern of global decline in ocean heat content over the last 5 years meticulously documented by Bob Tisdale; this OHC decline is sharpest in the Atlantic.
I think your report of the death of the current La Nina is exaggerated. The persistence of warm west Pacific water is linked to the rapid succession of La Nina systems from 2008 to now. The days of dominant and frequent el Nino’s are over – now it’s the turn of the little girl.

“Do models have one-way trustworthiness?”
Actually, models have one-way untrustworthiness. The GCMs [computer climate models] predicting AGW have been repeatedly falsified. They were all wrong. Every one of them.
There may be GCMs that predicted Anthropogenic Global Cooling, but I am unaware of any. If there are such models, please provide credible links, like I do.
Or, maybe you’re just “baffled” that reality debunks all the models predicting big time warming from small time CO2 [.00039 of the atmosphere].
Next, your attempt to argument that the poles are too different to compare is ridiculous. The model predictions were once again falsified. And your statement that Antarctica has “no land mass boundaries” ignores the fact that Antarctica is a continent. Best get up to speed on geography.
Finally, the “moral high ground” is held 100% by scientific skeptics, because the alarmist crowd refuses to abide by the scientific method. Their belief in [non-existent] CAGW has been debunked, but it is still causing immense economic disruptions based on a fake scare. $80 billion spent so far looking for AGW — and they still haven’t found it. Isn’t it time to turn off the money spigot?
The planet’s temperature is well within its natural parameters, and a change in a minor trace gas has not changed that fact. Nothing out of the ordinary is occurring. The false claim that “carbon” is evil is being pushed by folks who are more Scientologists than scientists. They’re doing it for the money. But why are you doing it? Because of your belief system? Follow the scientific method, and you’ll get on the right track.

Antarctic looks a lot more broken up on AMSR-E instrument than it does on NSIDC’s one
http://www.iup.physik.uni-bremen.de:8084/amsr/antarctic_AMSRE_nic.png
so I expect the NSIDC values to lower considerably in the next month back to normal.

I recall three years ago your posting about NASA say it was wind that blew the ice out ot the arctic in 2007:
http://wattsupwiththat.com/2007/10/03/nh-sea-ice-loss-its-the-wind-says-nasa/
Looking back at the iamages from Cryosphere Today, the ice by Svalbard island was very slow to develope in fall 2006.

You’re ridiculous. We’re talking sea ice extent. It can only grow away from the continent. It has no landmass boundaries to restrict outward growth like the arctic. By trying to make me look dumb, you only succeeded in looking so yourself. I’ve been on Antarctica, have you?

For Tony B,
In your analysis of prior Arctic Warming periods, you use a 1922 Weather Review article about Spitsbergen that you claim suggests that in the 20’s the Arctic was warmer than today.
Stories from past expeditions and whalers are of course always anecdotal and should be considered with skepticism.
A picture speaks louder than words when it comes to comparing the past with the present, and in that regard I would like you to comment on the following photo comparisons of Spitsbergens glaciers between the 20’s and 2002, courtecy of Greenpeace.

Oops. That hurts. Where did all that ice go since the ‘warm’ 1920’s ?
For R Gates : compliments on restoring some of the sanity in reasoning here.
It seems that WUWT readers tend to ignore evidence that does not fit with their agenda.

I’m not familiar with hmmm logic. However we have both made emininently testable predictions: you say recent Arctic ice loss is CAGW related and will continue, while I and others here say it is linked to cyclical changes such as the PDO/AMO and is now on a downturn – so recovery is in progress. So the logic of testing these opposed predictions is quite simple. Continued loss – you are right, recovery – we are. It might bump along somewhere in the middle – then we can go on arguing interminably….

Professor Ole Humlum of Oslo University pointed out in 2002 that this is a Greenpeace hoax. Blomstrandbreen is a so-called galloping glacier, which periodically advances and retreats, regardless of the climate.

Mike Jonas says: “Professor Ole Humlum of Oslo University pointed out in 2002 that this is a Greenpeace hoax. Blomstrandbreen is a so-called galloping glacier, which periodically advances and retreats, regardless of the climate.”
Thank you Mike. I was not aware that Blomstrandbreen is a surging (popularly called “galloping”) glacier. I did research surging glaciers a bit more and found that cycle times of 5-15 years are common.
Climate4you has a nice section on Blomstrandbreen and Greenpeace’s photo comparison :
http://www.climate4you.com/ClimateAndHistory%202000-2099.htm#2010:%20Blomstrandbreen%20in%20Svalbard%20begins%20new%20surge%20advance
“In August 2002 Greenpeace launched a campain to exemplify how ongoing climate was affecting glaciers world-wide. One of the glaciers which at that time received much attention was Blomstrandbreen in NW Spitsbergen, Svalbard. Although there is little doubt that 20th century climate change since the end of the Little Ice Age in Svalbard have been unfavourable for glaciers in general, it was however pointed out in August 2002 by the present webmaster that Blomstrandbreen was not an optimal choice of glacier to demonstrate climate effects, as this particular glacier (as many glaciers in Svalbard) is a surge-type glacier. ”
Even though Blomstrandbreen has started surging again since 2009, I found no evidence anywhere that the glacier has ever been back at it’s 1920’s level.
Overall, it seems that Spitbergen’s glaciers have suffered from long term AGW effects and are not returning to 1920 splendor.

Here is the Svalbard temperature record since 1912 :
http://en.wikipedia.org/wiki/File:Svalbard_temperature.png
The trend seems to confirm the trend in (even surging) glacier extent, and the general warming trend in the Arctic.

I’m not convinced it will fill up in a couple of days fishnski. I wouldn’t be surprised if it is still there by December 1 as there are high temp anomalies forecast for the Arctic region on the Canadian side coming up.
