Arctic Ice Extent Overtaking 2005 & 2006

October 14, 2013

By Paul Homewood




Just a month after recording the highest minimum since 2006, Arctic extent, according to DMI, has been growing so fast that it is now greater at this time of year than both 2005 and 2006.

Perhaps just as significant is the fact that DMI only count ice concentration of 30% and over, unlike NSIDC and others that use 15%. This would suggest that the thicker, more concentrated ice is becoming more predominant.

    Years not shown on this graph are 2003 & 2004.
    I’m not sure if data are available from DMI but according to IARC-JAXA (15% concentration), the 2013 figure was getting very close to the 2003

    On the 12th, the 2013 extent got to within 218,000 square km of the 2003 extent figure but fell back to 298,000 short on the 13th, due to relatively low growth on that day.

    Due to the rapid growth in extent during late October in 2003/4, it now seems unlikely that 2013 will now catch up with those years.

      It would be nice to get the NSIDC numbers, but the website is frozen at 30th Sep

    – In a world where greens aren’t green, and science skeptic orgs aren’t skeptical & scientists aren’t scientific there is a website called which The Australian Science Skeptics promote as debunking all that “silly denier” stuff
    ..when you check Rebutr it’s Climate rebutalls consist of pointing people to SkepticaScience (as if that is somehow a credible source) and their friends like Phil Plait
    ..seems very circular arguments to me ..and unscientific e.g. when I tested it with “Artic Ice icreasing” it gave me this
    (I note it choses a strawman to unpick “that we are talking about The Globe is cooling. )
    – It’s quite offputting that they seem to make up some alternative reality instead of deal with reality

    The DMI 15% figure is even stronger:

    Hudson Bay is cranking out the ice too.
