Antarctica sets new record for sea ice

Antarctic sea ice has set a new all-time record maximum over the weekend of June 28-29, 2014.

Antarctic sea ice has set a new all-time record maximum over the weekend of June 28-29, 2014.

The sea ice surrounding Antarctica, which, as I reported in my book, has been steadily increasing throughout the period of satellite measurement that began in 1979, has hit a new all-time record high for areal coverage.

The new record anomaly for Southern Hemisphere sea ice, the ice encircling the southernmost continent, is 2.074 million square kilometers and was posted for the first time by the University of Illinois at Urbana-Champaign’s The Cryosphere Today early Sunday morning.

It was not immediately apparent whether the record had occurred on Friday or Saturday. Requests for comment to Bill Chapman, who runs The Cryosphere Today, were not immediately returned.

The previous record anomaly for Southern Hemisphere sea ice area was 1.840 million square kilometers and occurred on December 20, 2007.

Global sea ice area, as of Sunday morning, stood at 0.991 million square kilometers above average. (The figure was arrived at by adding the Northern Hemisphere anomaly and the Southern Hemisphere anomaly. A graph provided by The Cryosphere Today showed the global anomaly as 1.005 million square kilometers.)

Although early computer models predicted a diminishment of both Northern Hemisphere and Southern Hemisphere sea ice due to anthropogenic global warming, subsequent modeling has posited that the results of warming around Antarctica would, counter-intuitively, generate sea ice growth.

A freshening of the waters surrounding the southernmost continent as well as the strengthening of the winds circling it were both theorized as explanations for the steady growth of Antarctica’s sea ice during the period of satellite measurement.

A number of prominent climatologists have discounted the growth of Antarctic sea ice, arguing that it is less significant to global circulation than ice in the Arctic basin.

Walt Meier, formerly of the National Snow and Ice Data Center and currently of NASA’s Goddard Institute for Space Studies, has previously said that Antarctic sea ice, which has little ice that survives year to year, is less significant than Arctic sea ice to the climate system.

“While the Arctic has seen large decreases through the year in all sectors, the Antarctic has a very regional signal – with highs in some areas and lows in others,” Meier said in 2013. “And of course, the Arctic volume is decreasing substantially through the loss of old ice. The Antarctic, which has very little old ice, hasn’t much of a volume change, relatively speaking.”

The new Antarctic record anomaly was more than 10 percent greater than the previous record.

The steady growth of Antarctic sea ice and its influence on global sea ice appeared to provide a public relations problem, at a minimum, for those warning of global warming’s menace. According to Meier and some other climatologists, global sea ice area is simply not a metric to consider when examining the climate system.

“A plot of global sea ice is just not informative or useful,” Meier said.

Global sea ice, during the course of the last year and a half, has seen its most robust 18-month period of the last 13 years, maintaining, on average, a positive anomaly for an 18-month period for the first time since 2001.

Phil Jones, of the Climatic Research Unit at the University of East Anglia, waded into the global sea ice analysis in 2013 as well.

“Adding the Arctic and Antarctic sea ice extents doesn’t make that much sense as the two regions are at opposite ends of the world, and the seasons are opposite,” Jones said at the time.

As I also reported in Don’t Sell Your Coat, the temperature at the South Pole has been declining during the past four decades as well.

    Given the different geographies at either pole I would expect the Antarctic ice to be a better proxy for world temps than Arctic ice. Not that either ice extent is a good proxy.

    E.g. sea ice extent is affected by wind more than air temp. That’s why warmists prefer all these proxies to the actual thermometer temps, when it suits their aims.

  2. Michael says:

    99 out of 100 physicians recommend a life saving operation and you want the opinion of # 100?
    That makes sense!?

    • Gary Meyers says:

      Your analogy doesn’t hold water! Maybe 99 quacks and one world acclaimed surgeon, would be more correct.

    • Willy Krusell says:

      That has to be the most quoted false figure ever.

    • Roger G says:

      Let see, Mr. Ambler quotes STATISTICS and Michael quotes a talking point. So Science is dead to talking points? Michael, that statistic you quote comes from a commissioned study/report/opinion request that was sent to the ‘Scientific Community’. I will paraphrase, OF THE # of respondents (Say 50 of 200 sent out responded) OF THOSE THAT RESPONDED 85% SAY GLOBAL WARMING IS A PROBLEM. My numbers and stats are for discussion and not to be quoted, actual data can be acquired. To include ALL scientists in your statement shows a true bias not based in science. If one was to look at the respondents I would be amazed to find that none of them had a financial incentive to promoting the THEORY of MAN MADE global warming. Michael, the earth’s temp has not gone up in like 12 years now. FACT. The amount of CO2 going into the atmosphere over that time period? WAY UP!!! FACT! Due to China, India etc.. You see Michael your arguments are based on models. Models are man made data input. At this point in this debate, basically ALL of the models are dead. Please bring back science before we re-enter the dark ages.

    • jimbow says:

      only if the 99 has be order to give that recommendation by the AMA, then you have to question it.

    • Jason Calley says:

      If 99 physicians, all of whom have been giving consistently wrong prognosis for decades, recommend an operation for me, then yes, I absolutely want a 100th opinion!

  3. Willy Krusell says:

    Since this story is being disseminated to the masses it would be nice if the actual areal quantity of ice was given vs just the anomalies. It is a bit confusing.

    • kingbum says:

      That would be slightly above 13 million sq kilometers right now…funny the last 18 months worldwide there has been above average ice and the anomaly is trending higher. ..not only that NOAA and NSIDC are predicting in August for the Arctic to be in positive ice anomaly for the first time since 1999…the facts are this Al Gore said we will have a ice free Arctic by 2014 in the summer back in 2007….Ice extent is above normal worldwide….hell Lake Superior didnt lose its ice completely until 3 weeks ago…dont sound like warming to me

    • David Appell says:

      Monthly NSIDC sea ice extent for both polar regions is here:
      ftp://sidads.colorado.edu/DATASETS/NOAA/G02135/

    • Sea Ice AREA “anomaly” set a record recently.

      Sea Ice EXTENT “anomaly” did not.

      NSIDC reports EXTENT. Cryosphere reports AREA.

      Sea Ice Extent total set an all time record in 2012 and then again on September 30 2013 when it hit 19.57892 million sq km.

      Sea Ice Extent “anomaly” maximum was Dec 21 2007 2.15 million sq km

  4. Mike Herman says:

    “A plot of global sea ice is just not informative or useful,” Meier said.

    But it is if it’s shrinking.

  5. tomwys says:

    Realize that when light returns to the southern ocean, the world is replacing 80% sunlight absorbing ocean with 70% reflecting ice/snow, and that the reflection is at wavelengths that CO2 cannot intercept and re-radiate. Guess where global temperatures will be headed!!!

    And some don’t consider it “informative or useful?”

    • Baronstone says:

      I have been trying to make people understand what the ever increasing amount of Antarctic sea ice could mean. People simply refuse to listen when you tell them that if the trend continues, it could very well tip the scales against us and cause the Earth to move into a period of glaciation. One thing is for sure, if that happens, we wont have to worry about sea levels rising because sea levels around the planet will fall by hundreds of feet as more and more water is locked up in glaciers around the world.

  6. A thin film of ice spreading out over the southern ocean does not mean the poles aren’t melting.

    Without a doubt, global ice VOLUME AND MASS are decreasing globally; at an increasing rate on both poles. This article cites surface area, not nearly as important an indicator.

    Look at it this way: You have a 10′ deep pond in your back yard with a spring feeding it. One day in the dead of winter when its wicked cold 80% of the pond is frozen solid down to the bottom. The side of the pond fed by the spring is still liquid and so is the surface above it. As spring comes the whole pond thaws but overnight the surface freezes an inch thick. Which is “more ice” the whole surface frozen an inch thick in the spring or an 10′ deep pond that’s 80% frozen solid by volume in the winter?

    Over the past 30 years:

    Arctic Ice Mass is decreasing exponentially and is down 30%
    Arctic Ice Volume is decreasing exponentially and is down 30%
    Arctic Ice Area is decreasing exponentially and is down 40%
    Antarctic Ice Mass is decreasing exponentially and is down 50%
    Antarctic Ice Volume is decreasing exponentially and is down 50%

    Antarctic Ice Area is indeed increasing… linearly, its up 8%

    That certainly doesn’t mean its “growing”. Charts to back up my assertions can be seen here:

    more BS.

    Another false statement.

  8. https://weather.gc.ca/saisons/sea-snow_e.html

    As one can clearly see the ocean waters around Antarctica are mostly below normal not above normal.

    There has been no warming around Antarctica.

    This article is a bunch of nonsense. Data does not lie.

    • David Appell says:

      “In recent decades, the Arctic has been warming
      and sea ice disappearing. By contrast, the Southern
      Ocean around Antarctica has been (mainly) cooling
      and sea-ice extent growing. We argue here that
      interhemispheric asymmetries in the mean ocean
      circulation, with sinking in the northern North
      Atlantic and upwelling around Antarctica, strongly
      influence the sea-surface temperature (SST) response
      to anthropogenic greenhouse gas (GHG) forcing,
      accelerating warming in the Arctic while delaying it
      in the Antarctic. Furthermore, while the amplitude of
      GHG forcing has been similar at the poles, significant
      ozone depletion only occurs over Antarctica. We
      suggest that the initial response of SST around
      Antarctica to ozone depletion is one of cooling and
      only later adds to the GHG-induced warming trend as
      upwelling of sub-surface warm water associated with
      stronger surface westerlies impacts surface properties.”

  9. David Appell says:

    If you want to discuss the “amount” of sea ice, you want to know its volume (or mass), not its area (or extent).

    Yes, the Antarctic SIE is increasing, and global SIE is back near levels of the late-80s/early-90s, though the long-term trend is still very much downward. But the volume of sea ice is not increasing, it’s decreasing.

    The Earth is losing a trillion tonnes of ice a year; here are the numbers:
    http://davidappell.blogspot.com/2014/05/how-fast-is-planet-losing-ice.html

  10. When it comes to climate sea ice area extent is what matters.

  11. Now they are trying to use the ice volume argument which does not hold water as a climatic factor in comparison to sea ice area coverage. Albedo is effected much more by coverage not thickness.

    In addition with a sea ice anomaly of over 2 million sq km in Antarctica I highly doubt sea ice volume has decreased.

    • David Appell says:

      It depends on what you are talking about. If it’s albedo effects, the area matters. If it’s heat changes, then you need to talk about volume or mass.

      I didn’t say sea ice volume was decreasing in the Antarctic — in fact, I said the opposite. Read my link.

    Sure David while Antarctica temperatures have shown no warming for years.

    Next falsehood please.

    • David Appell says:

      It is not a “falsehood,” Salvatore. I gave all the sources in my link. They are peer reviewed studies in major journals.

      You don’t get to dismss facts just because you find them inconvenient — that’s not how science is done.

  13. http://nsidc.org/data/seaice_index/index.html

    Meanwhile, both GISS surface and UAH satellite datasets show the Antarctic has been much colder than usual recently.

    note ANTARCTICA is colder then normal.

  14. Please reply if you find any flaw in the following data. 

    This is what happened in the Arctic during the ‘global warming pause’.

    ABSTRACT: “We use monthly measurements of time-variable gravity from the GRACE (Gravity Recovery and Climate Experiment) satellite gravity mission to determine the ice mass-loss for the Greenland and Antarctic Ice Sheets during the period between April 2002 and February 2009. 

    We find that during this time period the mass loss of the ice sheets is not a constant, but accelerating with time, i.e., that the GRACE observations are better represented by a quadratic trend than by a linear one, implying that the ice sheets contribution to sea level becomes larger with time.

    In Greenland, the mass loss increased from 137 Gt/yr in 2002–2003 to 286 Gt/yr in 2007–2009, i.e., an acceleration of −30 ± 11 Gt/yr2 in 2002–2009. 

    In Antarctica the mass loss increased from 104 Gt/yr in 2002–2006 to 246 Gt/yr in 2006–2009, i.e., an acceleration of −26 ± 14 Gt/yr2 in 2002–2009.

    The observed acceleration in ice sheet mass loss helps reconcile GRACE ice mass estimates obtained for different time periods.”

    • David Appell says:

      And I find that a quadratic fit to the PIOMAS monthly data on Arctic sea ice extent gives a acceleration of -16 +/- 2 Gt/yr2 since 1979.

  15. Temperatures are averaging below normal in ANTARCTICA which means they are well below freezing, the ice is not going anywhere.

    In the Arctic summer temp. have been averaging below normal which is far more important as to how much ice loss may occur then winter temperatures which are well below freezing regardless if the average temp. in winter is above below or just normal.
    So the loss of ice mass is an empty argument at best.

    • David Appell says:

      Arctic sea ice extent is 4.4% lower than this time last year.

      Over their entire datasets, starting in 1979, Arctic SIE’s trend is -53,300 km2/yr. The Antarctic’s is +19,400 km2/yr.

  16. David what matters for ice loss in the end are the number of days the temperature is above 32 not if the temperature is warmer then average.
