Arctic Goes Silent

There has been almost no ice extent loss over the last two days

Compared to the same date in 2007, when the East Siberian Sea was in rapid retreat due to strong southerly winds.

Compared to the September 2007, minimum

    Meanwhile, temps approach boiling point:

    Apparently temps are now interpreted as celsius, due to the heat index.

    So the extent stays still but the concentration thins out?

    The last few days 2007 was still going strong whereas 2011 has dropped off on daily ice extent reduction is true but I don’t think you can tell much from those maps, they don’t give and grading of ice cover like Bremen or Cryosphere does to indicate where next melt might most likely occur.

    Aren’t all winds southerly when close to the pole?

    Meanwhile, at the other end of the planet… whole article is paywalled but sounds inconvenient.

    Antarctic Ice’s Future Still Mired in Its Murky Past

    Summary

    “A new reanalysis by two NASA scientists of the three standard ice-monitoring techniques slashes the estimated loss from East Antarctica, challenging the large, headline-grabbing losses reported lately for the continent as a whole. Although not the final word, the new study shows that researchers still have a lot to learn about the vast East Antarctic Ice Sheet.”

    I still find it hard to credit that July 25 2007 and July 25 2011 are equal in extent – i.e. that there is as much red as green in the second picture. I reckon the difference must have been in the 15% to 30% concentration band. If so this would be good news for 2011 and worse news for 2007.
