NSIDC Busted!

Reader Chris71 has discovered the smoking gun on the NSIDC web site. Read on.

A few weeks ago, NSIDC put out this press release, claiming that 5+ year old ice is at its smallest level on record.

ice at least 5 years or older, is at its smallest level in the satellite record, representing only 3 percent of the total ice cover


The press release included the map below. This is a new style map which they just started in week 39 2015. The map below is for week 41 2015. All of their previous  1984-2015 maps have been deleted from their archive.


March ends a most interesting winter | Arctic Sea Ice News and Analysis

The good news is that Chris found one of their old style maps which had not been scrubbed from their website, and is annotated with the following text.

This graph is reloaded from ftp://ccar.colorado.edu/pub/tschudi/iceage/gifs/age${year}_${month}.gif every day and is available here as http://www.arctic-charts.net/ccar.colorado.edu/pub/tschudi/iceage/gifs/latest.gif



NSIDC has deleted the original graphs, but seem to have forgotten to get rid of the copy.


Here is where they get in trouble. Besides deleting data, NSIDC also deleted a lot of older ice when they switched maps. Note inside the circle how the red five year old ice has disappeared in their new maps.


The alterations are huge, and shown in the graph below. NSIDC deleted almost half of the five year old ice when they switched to the new maps. They also deleted about a third of the four year old ice, and some of the three year old ice.


Referring back to the top graph again, it becomes clear what they are up to. Had they used the same map set for the 2016 data as they did for all the other data in the graph below, 2016 would have had the most 4+ ice since about 2009. The graph below is junk science, useful only for propaganda.


It is bad enough that they switched data without telling anyone and used it to generate meaningless propaganda, but they also deleted all of the 1984 to week 36 2015 data from the disk. Fortunately they missed one map, which is the smoking gun. If the old data was that bad and needed to be deleted, then any comparisons made between the old and new data are extremely misleading- which is exactly what NSIDC was doing. They tracked that region of five year old ice for several years, and then suddenly decided it didn’t exist. Unbelievable.

They are busted, big time.

    I keep updating articles I am writing for papers or elsewhere and something new like this comes along. and I find I want to change the priorities of what I Am writing.

    and to Chris71
    CHEERS, wherever you are!

    And Tony/Steve, well done (again)

  2. Marsh says:

    AGW has never had a solid foundation and it was always anticipated ; when the “predictions” for melting weren’t there to be found… the lies & propaganda will make it so.! I still believe there will be a day of reckoning for extreme “Warmist” organisations ; the sooner the better…

    Congratulations to Chris71 and to you again, Steven, congratulations for having the analytical ability to detect and the courage to report FALSE INFORMATION disguised as “CONSENSUS SCIENCE!”

    On 4 JULY 1776 the Declaration of Independence proclaimed that we were endowed by our Creator with inalienable rights to establish, alter or abolish governments to protect our right to enjoy life, liberty and the pursuit of happiness.

    Less than 170 years later, on 24 OCT 1945, our independence as a nation was compromised by the decision of frightened world leaders to unite nations and national academies of sciences to “save the world from nuclear annihilation” by hiding the source of energy in atomic bombs.

    The National Academy of Sciences guided federal research programs over the past seventy years (1946 – 2916) to prevent the public from learning that;

    1. The source of energy in atomic bombs is indelibly recorded in exact rest masses of the 3,000 types of atoms that compromise all matter, as Aston explained in his Nobel Lecture in DEC 1922, and

    2. The Creator & Sustainer of every atom, life and planet in the solar system uses the same source of energy as atomic bombs and has this physical appearance:


    Public anger this election year at mainstream Democrats and Republicans, who worked
    together to deceive the public for decades, means the above empirical fact may leak past the Orwelluan Ministry of Scientific (UN)Truths,” especially if angry Democrats and Republicans join forces in a Trump-Sanders sweep of the November election!

  5. bit chilly says:

    has anyone contacted them for an explanation of this change ? climastrology is a funny old game, rather than use the same method to create a data set it seems every time a metric is not playing ball they just measure it a different way or adjust the measurements to suit the narrative.

    whatever it is they are doing it sure doesn’t meet any normal definition of science. once again thanks to tony for highlighting these issues.

  6. Richard Healy says:

    You know this is really quite silly. Since the data is obtained using passive microwaves and weather models there’s no reason why they couldn’t have just issued the younger sea ice age data to begin with. The fact that the data has changed may simply reflect a re-analysis based on recalibration or simply erroneous inputs into the model.

  7. David A says:

    There also appears to be a massive reduction in total ice???

    Re: Bit Chilly April 23, 2016 at 7:58 am

    I’ve read their web site if that’s what you mean? Wanna play “spot the difference” with me?


    • AndyG55 says:

      Jimbo, the village clown, hasn’t heard of the AMO, the LIA, or the Holocene Optimum (during which there was regularly ZERO Arctic sea ice).

      Jimbo, is a LYING, DECEITFUL, MORONIC P.O.S.

      Tell the TRUTH, for once in your miserable life.

      Can you even try to do that or is it totally against your character.

      • Jim Hunt says:

        Hello again Andy,

        See above: “This is a new style map which they just started in week 39 2015.”

        Where do you suppose I found “a new style map” for week 41 1984?

        Who here is an actual fact “a LYING, DECEITFUL, MORONIC P.O.S.”?

        • AndyG55 says:

          “Who here is an actual fact “a LYING, DECEITFUL, MORONIC P.O.S.”?”

          You can prove you are NOT by admitting that Arctic Sea Ice is still anomalously HIGH compared to all but the last 200-400 year of the Holocene.

          Until you have the GUTS to do that, on your web site, you are COWARDLY, DECIEITFUL, LYING P.O.S….. and you know it.

          Run and hide from the truth, dog s**t

        • catweazle666 says:

          “Who here is an actual fact “a LYING, DECEITFUL, MORONIC P.O.S.”?”

          You are, Jimbo.

        • AndyG55 says:

          Jimbo is mentally unable to face even the most basic truths about Arctic sea ice.

          This continued LYING to himself, as well as to his one or two “followers”, seems to be a deep mental state/sickness of his…… a natural part of his being.

    • AndyG55 says:

      And everybody here KNOWS already that your puke of a web site is nothing but a self-aggrandising load of tripe… well named as a monumental CON job.

    • bit chilly says:

      yep, lots of old ice around about the end of the last period the amo was in the cool phase jim . as it is moving into the next cool phase at the moment, i wonder how long it will take to build back up to that level or maybe a bit higher or lower.

      probably the 30 or so years it took to get to the high of the late 70’s from the 40’s.

    • bit chilly says:

      ps, do you have the original version , just for a comparison :). sometimes things get missed out in climate science when changes are made to visual depictions of various phenomena ,accidentally of course 😉

      • Jim Hunt says:

        Accidental changes such as adding bright yellow circles and giant text you mean?

        Assuming that you’re addressing yours truly, and referring to version 3 of the NSIDC’s Arctic sea ice age map for week 41 of 1984 it’s where you’d expect to find it. See the sea ice age section of the NSIDC web site.

        • AndyG55 says:

          How about you make some changes to your web site and start telling the whole truth about Arctic sea ice.

          Or are you too much of a LAIR and a COWARD to do so.

          1984.. just near the trough of the AMO, and at the end of a climb out of the COLDEST period in the last 10,000 years… of course there was more sea ice than basically the whole of the current interglacial. So what. Even now after a bit of natural warming from the AMO cycle, the Arctic sea ice level is still very high.

          You know that, but refuse to say so, because you know your AGW swillers from Exeter Uni would not like it.

        • Jim Hunt says:

          I’ve got a better idea Andy, How about Tony making some changes to his web site(s) instead?

          Such as prominently displaying the fact that “a few weeks ago, NSIDC put out this press release”


        • AndyG55 says:

          Your little CON of a web site professes to tell the facts about Arctic sea ice..

          But you know it doesn’t.

          You know it misses out on the full history, just to make a baseless propaganda LIE.

          Its all you have

          Its all you are.

          And empty propaganda LIAR.

          Why would NS-DIC change their methodology except to perpetuate the LIE.

          There is NOTHING untoward happening to Arctic sea ice levels.

          It is still higher than almost all of the last 10,000 years.

          You KNOW that, but are too much of a COWARD to admit it.

        • AndyG55 says:

          ” the fact that “a few weeks ago, NSIDC put out this press release”

          and just by coincidence, it allows them to show LESS Arctic sea ice.. WOW !!!

          Tom and Gavin would be so, so impressed. 😉

        • Jim Hunt says:


          FYI the Great White Con web site professes to:

          An ironic play on the title of David Rose’s series of “Great Green Con” articles in The Mail on Sunday.

          Is the word “irony” in your vocabulary?

        • gator69 says:

          It’s only “ironic” when you forget the twenty-one thousand who will needlessly today, because of your team’s advocacy.

          Is the word “monster” in your vocabulary Jimbo?

        • gator69 says:

          “…the twenty-one thousand who will needlessly DIE today…

          How about “responsibility”? Or “genocide”? Are either of those in you mealy-mouthed vocablualry?

        • AndyG55 says:

          Is the word HONESTY in your vocabulary, Jimbo?

          You seem to have absolutely no idea what it means.

          Still cowardly refusing to be honest about Arctic sea ice levels.

        • AndyG55 says:

          The ONLY thing you are honest about, unintentionally, is that your web site is one GREAT BIG CON job.

  14. AndyG55 says:

    Poor Jimbo, a rabid, irrational Arctic sea ice WORRIER and apostle.

    He seems to think the current losses of Arctic sea ice as the AMO climbed, and as we finish the continue the recovery from the LIA actually have some meaning other than purely natural cycles

    In the context of real time, these minor changes are INSIGNIFICANT and MEANINGLESS…

    Arctic sea ice is still very much on the high side of average for the current interglacial.

    but the WORRYING must go on, because that’s all he has in his insignificant and meaningless life.

    Jimbo, the time to really worry is if it starts to climb back up to the levels of the last major ice age.


  15. ScottyMorePower says:

    Did anyone ask the maintainer, Mark Tschudi, about why the ages are different?

    • Jim Hunt says:

      At the risk of repeating myself:

      “A few weeks ago, NSIDC put out this press release”


      • AndyG55 says:

        Gavin and Tonm would be proud of NS-DIC.. find another way to “ADJUST” the data
        odd that its ALWAYS in support of the AGW FRAUD.

        Speaking of FRAUD, how is that pathetic LYING CON of a web site going ?

        You know, the one whose owner is TOO COWARDLY to indicate the real Holocene history of regular ZERO summer sea ice for most of the first 7000 years, and its too MIS-INFORMED to mention that the reason there is STILL SO MUCH Arctic sea ice is because we are still very much at the cold end of the interglacial.

      • ScottyMorePower says:

        Jim Hunt, that press release is from April and does not indicate whether it is associated with the September map changes months earlier nor the deletion of the old maps.

    • Neal S says:

      And isn’t it obvious that four and five year ice is NOT going to disappear quickly. This is clearly fraudulent. It takes the blindest of the blind to NOT see this. (Or any CAGW believer) You can try to make all the excuses you want, but if you CANNOT explain how four and five year ice could so rapidly become much thinner, then you are just lying.

      They were either wrong or lying before when they claimed there was so much multi-year ice, or they are wrong or lying now when they claim there is so much less. Either way you cut it, there is error or lies or both. And considering that only the claim that there is less multi-year ice now supports CAGW, I know what I believe as a result.

      • AndyG55 says:

        “And isn’t it obvious that four and five year ice is NOT going to disappear quickly”

        NS-DIC can manage it.. just change the algorithm when ever you need to change the reality…… easy peasy…

        …. the natural way of the “climate scientist™”

        • Jim Hunt says:

          Strangely enough, no.

          …. you know , his high priest Richard Betts et and friends… who’s rings Jimbo undoubtedly kisses regularly.

          Lies and propaganda is all we will ever get from him or them.

          We have already seen that Jimbo has absolutely ZERO intent on EVER TELLLING THE TRUTH about Arctic sea ice over the full Holocene… choosing to concentrate only on the short period out of the coldest period in the last 10,000 years.

          TRUTH is not and has never has been in his vocabulary.
