January Arctic Sea Update

Arctic sea ice extent in January has recovered sharply since last year, and stands at the highest level since 2013, and higher than even 2005.

Much of it is 2m or more thick:

And ice volume is also up this year:

There was certainly a decline in sea ice extent and volume probably beginning in the 1990s, and it culminated in the large losses in 2007 and 2008.

But it is clear that, looking at both summer and winter data, sea ice has been stable since then, despite the occasional up and down.

    The minimum extent is looking as if it will be closer to normal in Antarctica this summer than last summer:

    Paul, thanks for the update. Yes, it certainly does look like Arctic ice by whatever measure has been relatively stable since about 2008 – for over 10 years now. I suspect Arctic ice and air temperatures are very strongly influenced by ocean water temperatures (heat content), especially in winter. And in turn, Arctic Ocean temperatures are strongly influenced by decade scale surges of warmer (less cold) water coming in from the Atlantic Ocean related to the AMO. If this is true, we may begin to see an upswing in Arctic ice statistics gradually over the next decade and a corresponding downswing in surface air temperatures. Since much of the recent global surface air temperature warming has been a result of milder Arctic winters, this Arctic change could potentially flatten or lower global mean surface air temperatures over the next decade. Time will tell.

      DMI, months ago, had promised me to take a hard look at this false statement on their ‘Arctic’ home page:

      The Frozen Sea
      Since the 1970s the extent of sea ice has been measured from satellites. From these measurements we know that the sea ice extent today is significantly smaller than 30 years ago. During the past 10 years the melting of sea ice has accelerated, and especially during the ice extent minimum in September large changes are observed. The sea ice in the northern hemisphere have never been thinner and more vulnerable.

      But, they have not.

        “But, they have not.”

        In any communication you have the ‘message’ and the ‘meta-message.’ The meta-message is the effective one which festers in the sub-conscious and fear-filled brain. The art of the liar consists precisely in putting across a meta-message wrapped in an apparently innocent message.

    Esoterica. Variations in Arctic ice extent of the past decades affects NO ONE.

      ??

      Pls explain for the hard of thinking. While I agree the past can affect no-one in this case it does allow us to understand the present, otherwise the present is essentially uninterpretable.

        The Arctic is generally UNINHABITED. There are few there to care whether there is more or less ice. More or less neither benefits nor harms anyone.

        People in New York or London caring how much Arctic ice there is, or isn’t, is just stupid. They wouldn’t know if someone didn’t tell them.

        BWTM: The best case for Man is LESS ice. Summer great circle route shipping between Europe and the Orient would be very beneficial. Man has dreamed of a NW Passage for centuries.

    No no no, this cannot be right. “Polar bears are affected by climate change and are increasingly forced on to land to look for food” and “Climate change is affecting Russian polar bears because of “Arctic sea ice diminishing as a result of climate change”.

    It must be true because the BBC says so:

      I found a 1922 book reference that says the polar bear invasions happen there when the sea ice gets close to the island chain’s coast – i.e. the presence of sea ice facilitates it. Also until quite recently they were quite heavily hunted here. So the truth is probably normal sea ice and a booming population.

    https://en.wikipedia.org/wiki/Greenland_ice_sheet

    “Analysis of gravity data from GRACE satellites indicates that the Greenland ice sheet lost approximately 2900 Gt (0.1% of its total mass) between March 2002 and September 2012. The mean mass loss rate for 2008–2012 was 367 Gt/year.”

    In the ten years between 2002 and 2012 Greenland lost 2900 Gt which represented –
    (0.1% of its total mass) (Yep, read the fine print.)

    YES – AN ASTONISHING, NAY STAGGERING EVEN, ZERO POINT 1 PERCENT OF ITS TOTAL MASS!!!!!!!!

    Are you effing kidding me? The uncertainty must be 10 times that much.

    Who measures this crap and thinks the numbers have substance???

    Probably those barely 20 millennials with their participation PhDs.

    Every year Greenland “loses” 400 to 500 Gt during the summer and gains it all back in the winter.

      They use a decimal point to show they have a sense of humor.

      “…gains it all back in the winter…”

      Actually, there probably is a net loss from the Greenland ice-cap. After all, we are still recovering from the age of the mammoths. However the last two years saw so much snow that Geenland was most likely in balance.

      What I find curious, is that the same people who seem to be hysterically cautious about any change in the Balance of Nature are totally reckless about demanding changes in human society which would amount to a complete leap in the dark. It is like Sheldon Cooper fussing about having pasta on the wrong night of the week while casually announcing he is taking a one-way trip to Mars!

        They are yelling “fire” and there should be consequences.

    Are changes in Arctic Sea ice extent understood in terms of global warming?

      Both RSS and UAH were up a bit, with their numbers for January. Perhaps this was related to the mild El Nino – which is dying anyway:
