Arctic Ice Decline Not Done, Yet!


Well, depending upon which data set one wishes to use, it looks like 2014 won’t have more ice extent than 2009.  But, it should still probably end up with more than 2013 for the minimum.  We’ll see.

    Here’s the source of that graph:

    For almost two years global sea-ice has been tracking the 1979-2008 average, month-by-month, almost exactly. The distribution has shifted slightly, though, with about a million sq. km more ice in the Southern Ocean and about a million sq. km less ice in the Arctic, over the last couple of years, compared to averages from the 1980s through 1990s.

    Scary, eh?

    Anthony ran an excellent article on the factors affecting Arctic sea ice –

    It is well worth the read.

    Today’s update on the CT area metric was higher than the previous day’s so it’s possible that the area minimum has already been reached. If so, it’ll be slightly higher than last years, purportedly with a greater thickness. While I don’t hate on PIOMAS like some, I’d prefer to wait until the next Cryosat-2 update to say it was for sure thicker.

    I still think the 11th was a good guess for the minimum…we’re about to find out.

      Very soon, Scott, we will. For the record, I don’t hate on PIOMAS, I just don’t believe they know what they’re talking about. I believe they fit their data to their expectations. I think, when we see ice return to the extent it was in the 90s, they’ll still tell us it’s thin and fragile ice and much less than it was before.
