   Just a few more gigatons of snow on land encircling the Arctic, is all.

   Try Sep 2nd 1996 vs 2010.

     How about 2011? What will it be then?

     Daniel:
     Seeing how we do not have satellite records going back 4,000 years we do not know.
     Due to “Improvements” in equipment and algorithms those alone could well explain any differences seen in changes one year over the next decades apart.
     The final answer without 10,000 years of “accurate” data : We Do Not Know! Your wild ass guess is as good as the one we get from NSIDC.

     Daniel, If you’re saying last September was much lower than the same date in 1996, you’ve just made a very important discovery: Here we are mere months later, and that disparity has vanished. What kinda damn death spiral is this? One that won’t spiral and it won’t die?

     You still have not answered this question:

     How much ice was there at the Arctic in summers during the Medieval Warm Period. Was there less? More? Same?

       How regional was the medieval warm period? What significance does it have on processes that work on time scales of the order of a century? Why is it more significant to see the ice extent at the end of summer than at the end of winter?

         Hi Daniel,

         Can you point me to an ncl script for displaying the WRF output surface temperature, and/or at various levels in the atmosphere?

       Daniel,

       “Why is it more significant to see the ice extent at the end of summer than at the end of winter?”
       —————————————————–

       Because ice at the end of winter doesn’t matter. There is so little light in the arctic at that time there is almost no albedo effect. The theory is the ice cap reflects light and keeps the world cool. Its ludicrous, but that’s the theory. If it is albedo, summer is the time it matters.

       PS, it doesn’t really matter.

   Dark purple concentration all in my eyes.
