Latest sea ice figures

Last week I wrote about how dire I thought the latest Arctic sea ice figures were. Since then I’ve been keeping an even a closer eye on them than I usually do, and if anything they look even worse. For the 27th of October, 2016 has the lowest sea ice extent on record (since 1979),  with only 74.6% of average, and far lower than 2012 (which is second lowest) by over 400,000 square kilometers or 4.6% by area. I know things can change, and I know it’s still early in the season, but remember you read it here first because I’ve heard nobody in the media make any mention of this slump as yet as they surely will.


It was only at the beginning of the month that the National and Snow and Ice Data Center [NSIDC] were saying that Arctic sea ice had increased at a rapid rate (see below), which at first it did do, as it bounced back from a very early minimum, but I think they may have spoken too soon.

Don’t look for any solace in the Antarctic either, because things are also pretty extreme there as well, with the value for the 27th of October also at a record low for that date (at 94.9% of average), with sea ice now tracking just below the x2 standard deviation area of the graph.

  1. You’re seeing conspiracies when there are none. Its true they swapped satellites and changed to using a running mean this year, but try and explain away the video of the decline in old sea ice if you can.

  2. But who do you believe – it is not an insignificant difference – and NSIDC have had technical and data revision issues (and dare I say climate change political correctness issues). Multi-year ice is a case in point – NSIDC revised their graph last year in a way (a) to make the loss seem greater and (b) actually disappear a massive chunk – all without a word!
