Half of the polar ice cap is missing: Arctic sea ice hits a new record low

Extraordinary melting of sea ice in the Arctic this summer has shattered the all-time low sea ice extent record set in September 2007, and sea ice continues to decline far below what has ever been observed. The new sea ice record was set on August 26, a full three weeks before the usual end of the melting season, according to the National Snow and Ice Data Center. Every major scientific institution that tracks Arctic sea ice agrees that new records for low ice area, extent, and volume have been set. These organizations include the University of Washington Polar Science Center (a new record for low ice volume), the Nansen Environmental & Remote Sensing Center in Norway, and the University of Illinois Cryosphere Today. A comprehensive collection of sea ice graphs shows the full story. Satellite records of sea ice extent date back to 1979, though a 2011 study by Kinnard et al. shows that the Arctic hasn't seen a melt like this for at least 1,450 years (see a more detailed article on this over at skepticalscience.com.) The latest September 5, 2012 extent of 3.5 million square kilometers is approximately a 50% reduction in the area of Arctic covered by sea ice, compared to the average from 1979 - 2000. The ice continues to melt, and has not reached the low for this year yet.

Why the Arctic sea ice is important
Arctic sea ice is an important component of the global climate system. The polar ice caps help to regulate global temperature by reflecting sunlight back into space. White snow and ice at the poles reflects sunlight, but dark ocean absorbs it. Replacing bright sea ice with dark ocean is a recipe for more and faster global warming. The Autumn air temperature over the Arctic has increased by 4 - 6°F in the past decade, and we could already be seeing the impacts of this warming in the mid-latitudes, by an increase in extreme weather events. Another non-trivial impact of the absence of sea ice is increased melting in Greenland. We already saw an unprecedented melting event in Greenland this year, and as warming continues, the likelihood of these events increase.

Huge storm pummels Alaska
A massive low pressure system with a central pressure of 970 mb swept through Alaska on Tuesday, generating hurricane-force wind gusts near Anchorage, Alaska that knocked out power to 55,000 homes. Mighty Alaskan storms like this are common in winter, but rare in summer and early fall. The National Weather Service in Anchorage said in their Wednesday forecast discussion that the forecast wind speeds from this storm were incredibly strong for this time of year--four to six standard anomalies above normal. A four-standard anomaly event occurs once every 43 years, and a five-standard anomaly event is a 1-in-4800 year event. However, a meteorologist I heard from who lives in the Anchorage area characterized the wind damage that actually occurred as a 1-in-10 year event. A few maximum wind gusts recorded on Tuesday during the storm:

McHugh Creek (Turnagain Arm)... ... ..88 mph
Paradise Valley (Potter Marsh)... ... 75 mph
Upper Hillside (1400 ft)... ... ... ... 70 mph
Anchorage port... ... ... ... ... ... ... .63 mph

The storm has weakened to a central pressure of 988 mb today, and is located just north of Alaska. The storm is predicted to bring strong winds of 25 - 35 mph and large waves to the edge of the record-thin and record-small Arctic ice cap, and may add to the unprecedented decline in Arctic sea ice being observed this summer.


Figure 5. An unusually strong storm formed off the coast of Alaska on August 5 and tracked into the center of the Arctic Ocean, where it slowly dissipated over the next several days. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite captured this natural-color mosaic image on Aug. 6, 2012. The center of the storm at that date was located in the middle of the Arctic Ocean. Image credit: NASA.

Arctic storms may be increasing due to climate change
This week's Alaskan storm is the second unusually strong low pressure system to affect the Arctic in the past month. On August 4 - 8, a mighty storm with a central pressure of 963 mb raged through the Arctic, bringing strong winds that helped scatter and break up Arctic sea ice. According to a detailed post at NASA Earth Observatory, that storm was in the top 3 percent for strongest storms ever recorded north of 70 degrees latitude. A study of long-term Arctic cyclone trends authored by a team led by John Walsh and Xiangdong Zhang of the University of Alaska Fairbanks found that number and intensity of Arctic cyclones has increased during the second half of the twentieth century, particularly during the summer. Dr. Zhang explained that climate change has caused sea ice to retreat markedly in recent decades and has also warmed Arctic Ocean temperatures. Such changes may be providing more energy and moisture to support cyclone development and persistence. The strong storms of this week and a month ago would have had far less impact on the ice just a decade ago, when the sea ice was much thicker and more extensive.

A sea ice decline double-whammy
The monster Arctic storms like we've seen this year have sped up the rate of sea ice loss, but increased water temperatures and air temperatures due to human-caused global warming are the dominant reasons for the record melting of the Arctic sea ice. A July 2012 study by Day et al. found that the most influential of the possible natural influences on sea ice loss was the Atlantic Multi-decadal Oscillation (AMO). The AMO has two phases, negative (cold) and positive (warm), which impact Arctic sea ice. The negative phase tends to create sea surface temperatures in the far north Atlantic that are colder than average. In this study, the AMO only accounted for 5% - 31% of the observed September sea ice decline since 1979. The scientists concluded that given the lack of evidence that natural forces were controlling sea ice fluctuations, the majority of sea ice decline we've seen during the 1953 - 2010 period was due to human causes.

Pretty sure that Leslie is going to be downgraded. Recon has not found anything close to hurricane force winds on the surface.
Pretty sure Leslie should be downgraded, but it won't be. The 11am discussion will include some fairly standard boilerplate, like this:
"The initial intensity remains 65kts, based on the latest readings from TAFB and SAB. This number is likely too generous. Aircraft reconnaissance this morning found surface level winds of 54kts, which agrees with the ADT reading."

The issue is that the storm is approaching Bermuda, and its intensity has been difficult to gauge or predict. The NHC really hates to cycle a storm through a downgrade every morning and an upgrade during dmax the next evening. Leslie's not a hurricane. But it's approaching land, and the NHC would rather err on the side of caution, particularly because the models continue to show gradual strengthening back up to solid Category 1 status over the next 24-48 hours.

So the advisory will hold constant, but we'll all know that - at least for now - it's merely a polite fiction.

No many people do, however you don't have to believe in the "holy Bibles" version of god to believe in a god. What makes the "Holy Bibles" god more special than other religion's god.
The absolute statements made by the religious right can get me going all the time.

Wake up people things aren't black and white because they are written in a book centuries old.

I can go on and on but I'll stop right now since this isn't going anywhere. Many religious types love to play victim so often yet forget how many real victims their are from the evil that has come out of religion for centuries.

OMG imagine if we had not invented satellites... what would the religious types be saying about those mean clouds up above that blew my families home away.....

And yet, just about the entire arctic region of the planet has been significantly warmer (5 to 10 degrees+ above the norm) with SST's to match, adn has been significantly warmer than normal for quite some time.

An abnormally cold or warm season is not climatologically significant. That is dictated by weather. If it happens with increasing frequency over the course of a couple decades, then it is something to pay attention too. Thus, your cold winter doesn't really imply anything climate-wise. However, the drop in ice and increasing temperatures in the arctic surface and sea surface temperatures are very significant.

Global temperature anomalies are calculated by looking at the total energy balance of the planet. Right now, that's around .6C-.8C above the norm.

Where in my comment did I say it was anything to do with climate change/GW????

I was just sharing fact about the winter we have just come through down here. Is that not allowed?

I think that probability is under-estimated. Scientist haven't been publicizing these prospects like they have AGW, because they can't pin it on man-made CO2 and govt policy. Fact is we only know about 10% of earth bound asteroids. The Tunguska event in 1908 was only a 100m diameter object that had the impact equivalent of 1000 atom bombs. No satellites where around to measure any effect it may have had the atmosphere at that time.

And people back then didn't have thermometers or barometers or any awareness of the world around them...oh, wait.

Thanks for the reply, Angela, but I'm sorry, as I haven't a clue what you're trying to clarify here, as it had nothing to do with what I was attempting to say. My point was basically this...

You're absolutely certain that "the majority of sea ice decline we've seen during the 1953 - 2010 period was due to human causes? (emphasis mine)


I'm not Angela, but yes. The IPCC report can probably be considered a conservative source that summarizes all the current research on the topic, though it is a little out of date. There have been several papers, including some recent ones, that indicate at least 70% of the sea ice loss has been attributed to human influences (greenhouse gases, soot, etc.).



As I said, I still think the jury is out about why the global climate appears to be getting warmer, and though you'd know better than I, I don't like absolutist statements indicating we know exactly why things are getting warmer, and thus what is truly driving the last couple of decades of Arctic ice melting.


There are no absolute statements in science. Thanks to the uncertainty principle, every measurement has at least a tiny amount of error associated with it.

And no, the jury is not still out on why it is getting warmer. That question was answered 125 years ago with the development of the theory of greenhouse gases.


Again, "human causes" may turn out to be definitively correct (and that we'll thank god for them as the Earth tries to sink into a cyclical "Little Ice Age"). But still, there are a huge number of instances where Occam's Razor has proven wrong, and that we'll find that a majority of the current climate change is being caused by changes in the electrical makeup of the Sun or the internal processes affecting the structure and flow inside the Earth, itself... or both.


You're misapplying Occam's Razor. Solar output has not increased, nor has there been any significant geological heating from the planet (the latter would not be something we missed as it would cause massive planetwide seismic and volcanic activity).

There are thousands upon thousands of scientists out there who have looked at and examined many different aspects of this issue. The most obvious and best supported answer is that the change in atmospheric composition is inducing a set of positive feedbacks that are causing the planet to warm up.




For example, though everyone will scream it's impossible, a gradual increase in the axial inclination of the earth... even a degree or two (many Inuits are claiming the Sun is setting in different areas than it should)... exposing the N. Hemisphere to more solar radiation for longer (with its long wave radiation effects on its greater landmasses), would probably also cause exactly the changes, and speed of changes, that we're seeing


Yes, the orbital and axial mechanics of the planet are well understood, and no that is not happening at the moment. It's not exactly something one would miss as changes in the axial tilt would affect the entire planet.


(especially given the continent of Antarctica is not seeing any global warming... its increased icemelt is caused by increased ocean temperatures at its edges).


That is incorrect. Antarctica IS seeing warming, just not nearly as much as other places. Part of that is due to the unique environment, but you can get more detailed information by doing a search on Antarctic warming and reviewing the papers published on the subject.

My post was simply a cautionary tale about the hubris, and the potential pitfalls, involved with making such absolutist comments about processes we're still struggling to truly, and completely, understand.


There is far more hubris in saying that dumping trillions of tons of sequestered CO2 into the atmosphere is NOT causing any issues.

Nothing can be 100% ruled out here, just like man cannot be 100% blamed for a warming trend.

But 100% isn't ever the standard in science. The chances that man cannot be blamed for a majority of the warming are slim.

Well, that's the problem, the Bible is a book about directing mankind to God, not a scientific document. The scientific aspect was left for us to explore. People back then were equally intelligent(if not more because the earth and our bodies weren't so polluted back then) but did not have the knowledge we have today. The Bible was never designed to be scientific document. You can't use it for or against man caused GW, it's as simple as that.

Facts about the Earth's current warming phase.

1) As the troposphere has warmed, the stratosphere has cooled.

2) Most of the warming has been due to an incresse in night time minima, rather than an increase in daytime maxima.

Interesting facts which, on the face of it, appear to rule out increased solar activity as the cause.



Both were also predicted based on the chemistry that validates greenhouse gases & their affects.
