Extent Of Multi-Year Ice Has Tripled Over The Past Decade

The fake news press continues to bombard the public with claims that Arctic multi-year sea ice is disappearing. As recently as one hour ago.

As with almost everything else reported by the press about climate, the claims are completely fraudulent. The coverage of multi-year sea ice has tripled since 2008.

This animation shows the huge increase in the areal coverage of multi-year ice.

In 2009, experts announced that Arctic sea ice was “effectively gone.” Since then, the coverage of multi-year sea ice has more than tripled, and experts say it is “disappearing.”

    So much fun is had when we simply “turn the tables”. I wonder if Ms Griff and Ms Rick will understand?

  2. Griff says:

    Well look here:

    That has a diagram of the age of the multi year ice

    See how little of it is over 2 years old? (and much of that is heading out the Fram strait)

    “Ice older than five years in age now only comprises 5 percent of the Arctic’s ice pack. It accounted for 30 percent of all Arctic sea ice in 1984…. Young ice has sprung up in its place and now accounts for nearly 70 percent of all Arctic ice, up from just 35 percent just three decades ago.”

    That’s the real situation.

    • Griff says:

      In fact that article has only 2016 map…

      This has 2016/17 comparison, showing MUCH worse situation as of March 2017

      • sunsettommy says:

        As usual you have no point to make, since you have yet to point out why a no Summer ice situation, should be bad for us.

        Only warmists have this unrelenting pessimism in their blood,even when there is no evidence to support it.

        • rw says:

          If the low point ever gets anywhere close to 1 M square kilometers, I would be happy to concede that Griff was right. Somehow I don’t think that’s going to happen.

          Tell you what Griff – are you a betting man? How about a $100/year bet for each year over the next 10 years that the minimum ice extent, as say shown by Nansen (or DMI or JAXA) doesn’t go below 4 M square kilometers (on the nose)? If the thrust of your arguments is correct, you should have no problem cleaning up. What about it? Maybe Tony is willing to serve as the bank – we can put down our money in April or (this year) in May, and the winner gets $200. Does that sound like a good deal to you?

      • Andy DC says:

        Propaganda, not fact. An excellent regugitation of the alarmist party line.

    • AndyG55 says:

      Griff, Arctic sea ice level is HIGHER than it has been for 95% of the Holocene.

      GET OVER IT !!!

    • AndyG55 says:

      Poor ignorant brain-wash griff,

      WRONG yet again

      Here is Russian comparison of firt couple of days of May

      FAR more old ice in 2017

      Note the amount of young ice off Alaska last year. none this year

      Note how far OLD ice extends across towards Russia,

      And you much extra OLD ice is down the coast of Greenland

      griff. ALWAYS perpetually and moronically brain-washed WRONG !!!

    • gator69 says:

      1984 you say! I wonder if Ms Griff see the irony. :lol:

    • sunsettommy says:

      Which mean it is still there,as it will always be, since even that the low point in the Holocene, there were still a winter ice pack,thinner I am sure but still a pack.

      You have been told dozens of times now that there have been long periods of time in the early Holocene,with little to no Summer ice,even while CO2 levels were around the 260 pmm level. Yet the Polar bears are still here today,the world still exist and Humans are still here.

      You still have yet to show why we should be concerned about it.

    • rw says:

      I’m intrigued that this climate central page doesn’t show any curves in its main graph other than 2016 (and 2017). In particular, the curve for 2012. Or for that matter 2007. Isn’t it odd that you could probably have made a stronger argument 10 years ago?

  3. AndyG55 says:

    A pixel count shows that on the Russian charts,

    OLD ICE is some 12% HIGHER than last year.

    OOPS, griff eats his stinky feet, yet again !!

  4. John Niclasen says:

    My comment is about ice, but in Greenland:

  5. AndyG55 says:

    “Old Ice” on Russian charts.

    2017 is :

    41 % HIGHER than 2008

    26.4% HIGHER than 2009

    30 % HIGHER than 2012

    Unfortunately 2008 is as far back as the comparable Russian charts go,

    But MASIE shows the current total extent ABOVE that of 2006. 2007, 2009, 2011, 2015 and 2016

    • AndyG55 says:

      Note, All “Arctic sea ice” sets differ considerably, but the HUGE takeaway is that..

      There is absolutely NOTHING UNTOWARD happening with Arctic sea ice.

      It is behaving exactly as anyone with any knowledge of the AMO would expect it to.

      The late 1970’s actually had EXTREMELY high levels of sea ice, up there with those of the Little Ice Age. That’s because it was only marginally warmer than the COLDEST period in 10,000 years.

      Current levels are still WELL ABOVE those of 90-95% of the Holocene.

  6. AndyG55 says:


    This is the way to go.

    Keep up the good work, China et al.

    Don’t let the AGW SCAMMERS rule your decisions. :-)


  7. Bud Akendorf says:

    Is there a video or article that compares climate models predictions to actual future data? For example, “here are what the year 2000 models predict over the next 10-20 years if no CO2 reduction is taken”. Then have reality vs prediction for years 2000-2017.

    It seems the models are good are “predicting” historic temperatures, but isn’t that like testing the model with the same data used to develop the model?

  8. Oliver K. Manuel says:

    Here in Missouri (the show-me state), the rivers are flooded, at least two major interstate highways are closed because of flood waters, and it’s raining more today.

    Climatologists are as respected as fortune tellers and witch doctors, and at least one of the residents knows what world leaders and paid consensus scientists seek to ignore:


  9. GW says:

    Tony, a few weeks ago didn’t you catch nsidc altering the multi year sea ice images from a few years ago, to make it appear as if there wasn’t as much ? What ever happened with that ?

  10. AndyG55 says:

    MASIE for day 123 : 2017 is above 2006, 2007, 2009, 2011 and 2016

    NSIDC has 2017 above 2004, 2006, 2015, 2016 (I suspect that 2004, 2015 will only be for a day or so.)

  11. AndyG55 says:

    OT but fun times in Victoria down under.

    The Unions are threatening strike action at Loy Yang power station.

    The Owner say if the action goes ahead, they will have to shut down (temporarily) both A and B plants and the coal mine.

    This is about 50% of Victoria’s electricity supply.

    It seems the people of Victoria might soon get a taste of what it would be like with no coal fired power. :-)

    This would flood on to NSW and QLD and SA.

    Fun times ahead.!

  12. Psalmon says:

    Somehow the Arctic Sea Ice never melts away (bottoms around 3-5M sqkm) and yet there’s no (or a tiny fraction like 5%) multi year ice in a system of 13-15M sqkm max and 9m average.

    That’s impossible.

    By definition, 1/3rd or more is multi year ice, whether it’s piled up or spread out, it IS 1/3 multi year ice…you’re being duped/distracted by the pixels or measurement detail. Wrong argument and/or measurement to make.

    • sunsettommy says:


      this is from EIGHT years ago…..,

      “But David Barber, Canada’s Research Chair in Arctic System Science at the University of Manitoba, said the ice was melting at an extraordinarily fast rate.

      “We are almost out of multiyear sea ice in the northern hemisphere,” he said in a presentation in Parliament. The little that remains is jammed up against Canada’s Arctic archipelago, far from potential shipping routes.

      Scientists link higher Arctic temperatures and melting sea ice to the greenhouse gas emissions blamed for global warming.

      Barber spoke shortly after returning from an expedition that sought — and largely failed to find — a huge multiyear ice pack that should have been in the Beaufort Sea off the Canadian coastal town of Tuktoyaktuk.

      Instead, his ice breaker found hundreds of miles of what he called “rotten ice” — 50-cm (20-inch) thin layers of fresh ice covering small chunks of older ice.

      “I’ve never seen anything like this in my 30 years of working in the high Arctic … it was very dramatic,” he said.”


      David Barber said in the article: “We are almost out of multiyear sea ice in the northern hemisphere,”

      That was EIGHT years ago!!!

      There are still a significant amount of multi year ice hanging around today,not close to running out.
