Arctic Ice Thickness Update
While I was on vacation last week, I monitored some of the comments and saw the interesting update about the Arctic ice thickness from the National Snow and Ice Data Center (NSIDC).
Earlier concerns about the Arctic sea ice was that much of the Arctic Ocean this year was covered by unusually thin, first-year ice, which is far more likely to completely melt out during the summer 2008 melt season, compared to the thicker multi-year ice.
According to the latest ICESat thickness estimates, it appears that the first-year sea ice in the Arctic Ocean so far this season is comparable in thickness to what it was in 2006 and 2007. Note the charts below. Why is that? The NSIDC says that sparse snow cover over the Arctic Ocean last winter resulted in less insulation from the bitterly cold air, resulting in faster, first-year ice growth. Snow was unable to accumulate last autumn since much of the Arctic Ocean was still ice-free, causing the snow to just melt into the open waters. Once the ice formed later in the fall, it accumulated more quickly than normal as there was very little barrier (snow) between the ice and the cold air just above the surface.
Now, correct me if I am wrong, let's assume that there is even less sea ice coverage at the end of this year's melt season compared to the last two years, based on their above explanation wouldn't that mean that there would be even less early autumn snow accumulation compared to last year and thus another slight increase in the first-year sea ice thickness for 2009?
You can also see that the multi-year ice this year is clearly much thinner than the past two years. The NSIDC notes that this could be due to two factors. melting at the underside of the ice that was observed in the summer of 2007 and the greater than normal export of thick ice out of the Arctic Ocean.

The arctic started the freezing season with the least ice since they started measuring it. If the arctic continued warming, the new ice should have been thinner than usual and cover less area than usual. Going into the melting season, the thin new ice should have quickly melted and the additional arctic warming should has eaten into even more of the multiyear ice than ever before.
Obviously that didn't happen. Let the excuses begin.

hmmm;
No urban heat islands in the arctic ocean.
So, how can there be so much loss of sea ice?
Can you say greenhouse gases; CO2 and CH4?
Evil Oil Executive will of course have their dis-information available for those gullible enough. Maybe they will try to claim there are under water volcanos to blame.

Wow ..........global warming now causes "bitterly cold air" AND more ice ..... Wow ......What more can I say!
The spin doctors have a lot of work to do on this one! With sooooooooooo much money invested by the AGW camp (to prove the A in AGW), they can't afford to let this go unchallenged!

As of today Arctic sea ice extent is midway between 2007 and the average 1979-2000 level. You can see it monitored daily at this site:

Posted by James | July 27, 2008 5:19 PM
Probably true, but, since ice extent is about 1 million sqkm ahead of last year (and most of the melt last year occurred between mid June and mid July it appears that the desire for an ice free pole is a pipe dream.

Posted by paulm | July 27, 2008 7:29 PM
"So why is the first-year ice thicker than anticipated? Sparse snow cover last winter may have hastened its growth: less snow on the ice means less insulation from the frigid winter air, and faster ice growth. Much of the snowfall over the Arctic Ocean occurs in early autumn, but early last autumn much of the Arctic Ocean was still ice-free and could not collect snow. Once the ice formed, it grew quickly."
What a crock.
Put another way.
The "thin ice" was supposed to melt quick this year. This should have meant that Artic sea ice would have melted fast, probably to lower levels than last year. The problem is it's not happening. So hence the ready excuse provided above.
Lets add it to the list.
1. Thin Arctic ice-AGW
Thick Arctic ice-caused by less snow, which resulted in less insulation, creating more ice, all in fact a result of less ice last year, caused, of course, by AGW.
Makes perfect sense.
2. Shrinking glacier-AGW
Growing glacier-more snow due to AGW
3. Warm winter-AGW
Cold winter-weather stupid. No one said there wouldn't be cold spells even with GW. Oh yea, and more extremes.
4. Shrinking ice sheet-AGW
Growing ice sheet-more snow due to AGW
5. Less Artic ice-AGW
More Antarctic ice-a variety of factors, none of which involve it being colder. Besides it's not significant.
6. More hurricanes-AGW
Less hurricanes-AGW
Makes sense right.
7. Droughts-AGW
Heavy rain and floods-AGW
I can't imagine why anyone would be skeptical.
Posted by iceman | July 27, 2008 8:57 PM
The implication of this story is that NSIDC didn't bother to measure the actual ice thickness before predicting it's demise in June. The Canadian Government had reported all winter that ice was recovering to near normal thickness - but that apparently wasn't significant enough to stop the publicity hounds in Boulder.

Posted by Patrick Henry | July 28, 2008 12:46 AM
iceman/PH: basically they are trying to go for the "thickness" now because the "extent" ain't happening. Predict NH ice will increase both in thickness and extent... from now on and will probably be above anomaly for much of 09. We shall see....
Of course SH ice is extraordinarily ABOVE anomaly considering it ain't gone below once in the last 11 months! (1-2 km2 million but thats not important....)

Anonymous,
More disinformation and misinformation.
Arctic sea ice extent is 1 million sqkm ahead of this time last year and doesn't appear to be melting as quickly as last year (regardless if it is 1st year or thin).
Antarctica sea ice extent is setting another record for extent this year even though there aren't any UHI there either.
Did CO2/CH4 levels decrease in the Arctic and Antarctic?
Alaska is having the coldest summer on record - http://www.adn.com/life/story/473786.html - guess the CO2 and Methane levels in Alaska must have decreased too, or maybe increased CO2/CH4 is causing lower temps? Of course what would help is if the eco-tourists would stop traveling to gawk at the melting glaciers, dumping tons of soot from their cruise ships on said glaciers and ice, increasing the melt rate.
Posted by Bill | July 28, 2008 8:26 AM
It is apparent that the AGW proponents have a poor understanding of the arctic climate and the mechanisms which affect the ice sheet. They see an anomaly and jump to false conclusions because it supports the AGW hypothesis; that isn't science. If the computer models were accurate then they would have predicted this but they didn't.
The AGW folks are not willing to admit that they don't understand these phenomena and, instead, try to reconcile contradictory real world events with AGW dogma. They should simply be honest and declare that they don't understand why the ice sheet isn't behaving the way they said it would. They lose credibility with every false prediciton.

HI all - I was looking at this over the weekend & it is of interest that the ice melt rate starts to slow & is near flat by August 20th & then the freeze begins in earnest about ( surprise ) Sept 20th ... the start of total darkness at the pole.

Soft hail ... isn't that graupel? I believe it is a type of snow ... or at least it sure seems to be snow when you are skiing / boarding on it and the Swiss have a name for it. Soft hail seems to be an oxymoron , in that if it ain't ice, it ain't hail.
Again it makes for the most amazing skiing since the tiny balls are like styrofoam ball bearings under your feet & it is hero snow, almost impossible to not ski well & fast on. Also, on TV I saw a snowman made from the stuff & since there is no such thing as a hailman it has to have been snow!!

SammyK: Think of sitting on a beach in Acapulco, and look at that Margaretta you just ordered, then watch the ice melt as the sun bears down on it. That is what the Arctic will be like in five years, and all the perma frost around it. And you'll be sitting there saying"could I have a glass of ethanol this time, my car won't start. Just look at the images and you'll see the transition, and if you go there don't forget your canoe. Don't light any matches around those bogs either. Methane, is what I don't look forward to.
The Earth is warming and I don't give a damn what the IPCC predicts. There are too many sources, from too many areas of science that agree that global warming is a reality. If America doesn't get it's alternate energy act together soon then we won't be able to capitalize on that.
I don't think stalling anymore is a profitable soulution, and if China now is producing the majority of solar panels, why aren't we. Even if I thought like PatrickH that the ice age is starting, as a venture capitalist, I would go into the energy field yesterday. You guys don't sound like Republicans anymore. Look what the largest owner of natural gas in the world just did. He made an agreement with Texas to build the worlds largest wind farm. So!Wake UP!!Americans.When the price of gas went up, that was the time you knew we had to change or die,as they say in New Hampshire. Everyone say's Ya! we need gas, but not off my state. Just happened in New Jersey. Got the picture yet!

Brett do any of these maps or graphs exist for years in the 70s,80s,90s? I would assume flucuations are the norm for here, depending upon wind, snow , etc as much as the temp. I do agree with the assumption the more melt the more first year ice next year, just for the fact that there is more open water to freeze and less area for snow to insulate so the first year ice would also be thicker, correct. And say that area stays drier than normal and it does cool over the next X amount of years, couldn't it build back up fairly rapidly and in a few years these maps could look like the coming of the next ice age? Climate change just won't quit. Also I had a low of a pleasant 47 this morning, refreshing.

Thanks for the additions. I'd forgotten about the dreaded "equipment failures".
The fact that those "equipment failures" only seem to happen with findings that punch holes in AGW, well that's just a coincidence.
Posted by iceman | July 28, 2008 9:04 PM
Josh,
Last August NSIDC had an animation in one of their sea ice updates that shows the progressive decrease in multi-year ice since 1982. This gives us a rough idea of how the thickness of the ice has changed over time since older ice tends to be thicker ice. Most of the old ice has historically been pushed out of the Arctic through Fram Strait (between Greenland and Svalbard), but is usually replenished by first-year ice that didn't melt. Typically about 70% of first-year ice melts during the course of the summer, leaving 30% to thicken during the following winter.
Yes, if we have several cool winters in a row, we could see a build-up of multi-year ice again. The obvious question follows: will we?
Here's a link to the NSIDC report in the archive page. Scroll down for the animation; it's figure 4 in the August 22nd report.
It's also worthy of note that melting season in the Arctic has about seven more weeks to go. I highly doubt this year will see a minimum extent eclipsing last year's record low, but we could still easily see the extent dipping below the previous record from 2005.
I do agree with the assumption the more melt the more first year ice next year, just for the fact that there is more open water to freeze and less area for snow to insulate so the first year ice would also be thicker, correct.
I just want to clarify; the NSIDC article did not say the first-year ice was thicker than normal; they said it was thicker than expected. The numbers accompanying the three thickness maps back this up; this year's new ice is marginally thinner than (i.e. about the same as) the previous two year's new ice.
It's not an obvious result, and it may not be a consistent one year-to-year depending on winter and spring weather in the Arctic. This year the Arctic had a particularly cold winter (as is evident by the significantly larger sea ice maximum extent compared to the past several years). If it had instead been a more typical or a warmer Arctic winter, the first-year ice would very likely have been much thinner.
Consequently, I can't think of any circumstance in which Arctic sea ice soon returns to positive anomalies for an extended period of time as Vincent suggests, especially seeing as the Arctic hasn't seen a positive sea ice anomaly in over five years. Given that history, I'm not ready to share his optimism. If we get another cold winter this year, I might be willing to reconsider.

Rick Ressler,
Every person, from both sides of the argument, should watch the videos that you posted and also the trailer videos about the sun and testimony from former environmental movement organizers, that accompany them.
They clearly show the misguided history of the environmental movement and how easy it is to recruit the mis-informed.
If you watch these videos with an open mind and still don't get the truth in it, then you deserve to be a mis-guided follower, until the next cult comes along and recruits you.
I laughed out loud when I watched how many hundreds of folks at the "save the earth rally" gladly sign the petition to ban H20, when it was presented to them in the full chemical pronounciation and were told we must get rid of it because it was getting into all our plants and food and what we breathe.
It is a taste of reality that is the reason I am a sceptic and not a lemming for the very rich and devious AGW spinners.
How sad that so many seemingly intelligent folks can be taken in so easily, by so few, with so little effort through a simple, well funded, mis-information campaign.

It would have been a miracle if the ice had melted completely in the North pole region!
The trend is there though! It probably will go sooner rather than later unless some thing changes.

Steve, I thought you knew the answers to these easy questions. You keep writing a small p with the larger H. That is incorrect as PH was nicknamed the power of hydrogen only. No meaning for the small p.
Secondly, it's not about saltwater fish but shell making because to make shell fish you need more alkaline not more acid(calcification). Shells won't dissolve, but they will not be as dense. There has been a loss of one unit,10 as a negative logarithm. .Read the Discovery of Global Warming by Spencer Weart. I thought you knew more about these topics then you apparently show because of your questions. Well your still good at Algebra.
Next time I think you should make a thesis instead of trying to tear down what other people hold true. Start with Global cooling, if you can find such a sparce topic. Thanks, KIPP

MARK-Denver,CO:: So today you are an environmentalist. I was finding a silver lining in the California disasters and was not sticking to the main AGW consensus as skeptics stick to denial. Anything I have learned about climate is that it is always changing. How much soot will land in the Arctic I don't know. I don't presume that the soot will re-freeze however. In my first postings I had discussed going out to California, where firefighters new that it was Global Warming that is making the difference. More land is giving up it's frost and moving north. They call them Super fires. Soot does effect the reflectivity of
long wave infrared bands. What is your point. If you are saying that fires are bad then I agree totally. It is not paradoxical that good and bad things happen at the same time. We must have biomass as part of the carbon cycle, and because it is our mother Earth, that we must learn to love, and not destroy.

This single picture of three subs in open water at the North Pole in 1987 tells us that the idea the Pole was once brick hard, and now is falling apart, isn't correct. http://www.john-daly.com/NP1987.jpg
If such a situation reoccurred, do you think the media would reassure us, saying, "Don't worry; it happened back in 1987 and the world didn't end?"
Probably not. That doesn't sell papers as well as a blaring headline, "Open Water At North Pole! Scientist Predicts Disaster!"
I wish I had more time to sit about watching ice melt, but I can only visit this site occasionally these days. It's good to see that the ice-watchers are on the job.

Yes, the videos are revealing. I also thought the comments from the former co-founder of Greenpeace were cogent. The environmental movement has become a political movement and the evidence in support of this is compelling.
What's scary is that there are too many people (voters) who would gladly sign the petition to ban dihydrogen monoxide if someone knocked on their door. Many of these folks simply don't think for themselves and are quick to jump on any bandwagon which claims to be about saving the planet. Even the leaders of the rally and the spokesperson couldn't answer fundamental questions in defense of their cause.

Even so, (and that particular area has been breaking up since 1900), sea ice extent is 1 million sqkm ahead of last year http://nsidc.org/data/seaice_index/images/daily_images/N_timeseries.png and, while it is still below the 20 year average, it appears to be headed towards the 20 year average rather than last years record (no ice free pole this year I'm afraid).
If you want to see the current weather/temp in the Arctic go here http://www.arctic.noaa.gov/latest/noaa1.jpg.
Also, Alaska is having the coldest summer on record and there appears to be more ice than normal in some areas of the Arctic.
The 'Arctic' in not 'breaking up', that's a misleading exaggeration of a relatively normal process, plus, breaks in ice sheets are caused by pressure, not melting.

Yep, once it got started in 2007, it did well, but the later start, warmer ocean, and earlier end ensured that the first year ice that formed was THINNER by 0.2m. Your bias blinds you to facts. You zeroed in on a factoid instead of using a holistic approach. Please open your eyes.

What does amaze me is the gullibility with which our populace is able to embrace AGW with such a heightened sense of guilt.
Look to advertising and the media in general to answer this.
We are constantly told via advertising that were too fat too thin, have poor skin, need more clothes because ours are out of date or dont look good anymore - etc buy buy buy - all based on the guilt complex! Just watch advertising for a while and guilt is the dominating emotion that carries forward the sales pitch.
Couple this with fear propagated by the media at large and we have fanatical tendencies exhibited by a populace that can be directed at will by media hype and speculation.
Sensationalism if you like and ruling by fear via the media services.
Services indeed - who do they really serve?
The oldest tricks are the best and with our nurtured sense of guilt we have bred a fascist green movement on a religious mission to stamp out life as we know it.
Keeping us squabbling among ourselves while the banks manipulate our economy beyond all recognition and with the use of our own money to do so in the first place!
DIVIDE AND CONQUER!!
You all should be ashamed of yourselves - suckered in by the highly evolved feudal system and manipulated by a sociological experiment of global proportions.
You all deserve the bleakness that is coming this time ironically it really is Anthropologically Caused but has nothing to do with the weather.
Hope it works out for you all!
