Denmark Rottenness Continues

The Danish Meteorological Institute continues to show less Arctic sea  ice than last year.icecover_current_new (9)

However, their maps show slightly more ice than last year.

Due to very cold temperatures, there is almost no melting going on in the Arctic.

It is surprising that there is any melt occurring at all, because our top scientists say that the Arctic is ice-free.

    Hey.. is that black line heading UPWARDS slightly ? ;-)

    Here’s the latest JAXA Arctic surface melt map Tony. I think it’s fair to say it shows more than “almost no melting going on in the Arctic”, don’t you?

    Since when has Jonathan Amos been one of “our top scientists”?

    Jim; I appreciate your input. In your estimation what ice loss is due to AGW and what ice loss is due to natural variability.?

    I always though the saying of “moving the goal posts” was a figure of speech, my god it actually happens.

    How long are you going to continue this farce, Tony? As I already explained your bs…

    DMI explains why there is a difference of 1.4 million sq kms of winter arctic sea ice between 2015 and 2016. Of course, most people here thinks it is something rotten in Denmark, but get over the politics and pay attention to the science.

    A new algorithm with a much higher resolution coast mask was used following the summer of 2015. Although the new graphs are drawn with this difference in total extent accounted for, the maps before and after this change are not comparable. They show side by side comparisons of a winter 2015 map and a winter 2016 map with very different coast masks. They conclude this explanation with the sentence, “A comparison of the 2015/2016 sea ice extent with previous years does therefore not make sense.”

    There is no mystery here, DMI put a warning about this ‘apparent divergence’ in bold, bright red lettering right under their graph with a link-

    If you want to understand how completely wrong Tony is, you will have to click on that link and read a few paragraphs.

    It is clear that Tony uses DMI when it suits his purpose. But this… this is just wrong. Pretending that DMI is now tricking you because Tony refuses to acknowledge their clear explanation why ice maps can not be used to compare arctic sea ice graphs is completely indefensible.

  6. mogur says:

    Here it is in layman’s terms. DMI changed their coastal mask to a very much higher resolution. Because they are no longer masking a large coastal area of ice, the maps will show a significant difference in total sea ice extent. The new maps will show more ice. Their graphs are adjusted for this difference, so new maps are on par with old maps. That difference is about 1.4 million sq kms during winter, since there is a lot of sea ice hugging the shoreline in the winter. The difference lessens during the summer months, because there is significantly less relative coastal ice during the summer ice than the winter ice. We are in the middle of the melt season, so the difference between comparisons of ice maps and ice graphs is about 3/4 of a million kms. Tony is fooling you.

    Very strange… Where is that little black line heading to !

    Sea ice can’t possibly be increasing, surely .

    • Jim Hunt says:

      Just for once I agree with you Andy! At this time of year the amount of sea ice in the Arctic cannot possibly be increasing.

      Your “logic” is most intriguing. When DMI extent decreases you blame the wind, but when the winds change and create some divergence in the Central Arctic Basin “sea ice is increasing!!!”.

      In actual fact surface melt has increased markedly, particularly on the Pacific side of the Arctic. Where is the little red line headed do you suppose?
