Dead Ice

The Antarctic ice is melting and is well below average for the first time in 3 years.  Global sea ice is also below minimum. It looks like the death spiral has come to pass….

Except that it is winter there and that means it is simply not freezing at a typical rate.   It still spells doom though, I’m just not sure how.

  1. What do you think has happened to all the Ocean heat required to bring about that melt?
    The Ice is around -20 C most of the time so there is a lot of energy being drawn from the Oceans and Atmosphere.
    Take a look at the Antarctic on NuSchool’s earth.

    1. Actually, it is just freezing less but I get the point. I need to see how much of the extent loss is related to simple compression due to wind/current also. Sometimes it isn’t really less ice but this is a pretty major shift so that seems unlikely. It looks like it may be a current flow change bringing some warm water in contact with the ice..

  2. Jeff, I don’t really know how to read all this “stuff” I found, but there may be something to it. You might understand it better than me. Sea ice data used to be recorded using something called Goddard. This is the first year data source is listed as NRTSI-G. Here: down at the bottom of the page. Then, there was a problem with the satellite reporting the sea ice data HERE: There may be more dominoes yet to fall.

        1. I recall a situation with the temperature record in the past, a problem started with data loss and was later recognized to create a trend bias that required a satellite switch and some data replacement. It’s not likely that it will happen again but it is worth watching.

      1. The West Antarctic Rift System contains five active sub-ocean volcanoes, with geologic thermal activity from the Mcmurdo volcanic group and Marie Byrd land area, and continues on to the Larsen b ice shelf area.
        Maybe I’m missing something in the translation, but I can’t understand how Antarctic ice goes from an all-time high to a three year low in a year. If so, the planet hasn’t warmed for the last 15-20 years. So it can’t be true unless something else is going on.
