Big Chill in October Arctic


ESL2018290to301Siberian Big Chill in last Ten days

With the Canadian Arctic already frozen over, the action has moved to the Russian side.  The image above shows massive gains in ice extent in East Siberian and Laptev basins. East Siberian added 383k km2 for a total of 821, or 75% of last March maximum.  Laptev was mostly open water in September, but added 550k km2 in the last ten days for a total of 650k km2 or 72% of last March maximum.


The graph shows MASIE reporting ice extents totaling 7.8M km2 yesterday,  400k km2 below the 11 year average (2007 to 2017 inclusive).  Note how 2018 started on average, then went fairly flat the first week or so, falling 900k km2 below average.  Recent gains in ice extent exceed average gains, closing the gap.  Presently, 2018 is about four days behind the average, tracking above 2016, 2012 and 2007. NOAA’s Sea Ice Index is matching MASIE through most of October.


The current IMS Snow and Ice Chart shows how snow is covering Siberia completely, and has spread over northern and eastern canada.

    Bob, what should Gore be saying?

      I changed the date from 2016 to 2213! (even then, he’d be wrong, but who will know???)

      BTW, if you’d like to look at a review draft of my book (nearing completion) in pdf format, send me an email.

      Title: “Is Climate Change Really Human-Caused? / The trial of carbon dioxide in the court of public opinion”

      The evidence is compelling that it isn’t… written for non-scientists and scientists, the reader is cast in the role of a juror. Looking for any feedback. I can send you a link to my dropbox account where the pdfs for each section reside.

    I am waiting for a really big freeze ay 20% above the long term average. This year appears to be just catching up to average.
