    NEWS.SKY.COM
    An Arctic research station, which is located 10,551ft above sea level, saw above-freezing temperatures for more than nine hours for the third time in less than a decade.

     

    Remember the Climate change deniers, back in 2012 (?) when we saw the first 'melt' at summit telling us that it was a 160 yr 'cycle' of melt over the summit?....this was now the number 3 instance of the last decade......I wonder what they would say today?

    We've been treated to what 'average seasons' now leave the pack like come Sept but what of the 'rogue' years like 07' /12'?

    I worry that most years we are only 3 or 4 weeks away from melt out by the time refreeze begins. Pump in that energy over a freak year and the ice will just go (probably in late Aug?)

    Since 2012 the continued degradation of Arctic ice has not halted. The floes are small and faster to form, the percentage of ice that is 1st year ice continues to increase (weakest ice) whilst older ice fails. We lost the last 'paleo cryogenic' ice in 2010 so how much 10 year old ice now sits in the basin?, 9 year old ice?, 5 year old ice even???

    Agreed BFTV!

    Back in the late noughties I began noting the seasonal stress on the ice at Spring tides, I was assured it was a normal occurrence.

    This 'denaturing' of the pack , early doors, means that the ice 'gluing' the floes back together is very weak and fails quickly once melt pressures arise.

    We then get mechanical weathering of the floes as the crash into one another chipping off edges/further shattering floes

    Small floes move much faster than large floes

    This year it is not the 1st year ice giving way but the old ice to the N of Greenland and the CAB directly (our best ice?)

    I do not like it Sam I am, I do not like this drift and scram!

    I know it's very early doors but I'm already not liking what I'm seeing in the Arctic?

    We've all seen the animations of seasonal ice loss and just how much Fram takes out of the basin

    This year we seem to be shipping 'good ice' at quite a rate so stretching the ice from the feed areas (CAB/N.Greenland?)

    Will this lead us to a more vulnerable pack in these 'feed regions' allowing more open water, earlier on in the summer, across the areas that normally hold onto our best ice over summer?

    The Hole In The Ozone Layer

    I seem to recall that when the polar night jet becomes misshapen (or bi-lobal/tri -lobal?)  sections can find themselves in sunlight as the lobes loop over lower latitudes so meeting the returning spring sun up at their altitudes?

    I think Feb 2014 saw a sizable hole over the UK (IIRC?)
