Rate of arctic summer sea ice loss is 50% higher than predicted.

  1. Ove – they’ve been going on and on about this for years and predicting an ice free Arctic summer yet it hasn’t eventuated. Now they are predicting in in the NEXT decade. If it’s caused by a decreasing temperature gradient between the equator and poles how come the Antarctic is fine?

    Obviously there is another factor that affects the Arctic only, and it’s not AGW.

    At the end of the northern winter ice coverage was normal.

    If it was AGW causing the ice loss surely it would occur equally in the winter and the summer.

  2. Janama, I sense a hint of desperation. Parse it any way you like and the extraordinary Arctic summer ice loss demonstrates the real world effects of an enhanced greenhouse effect. Shifting to comparisons with Antarctica (parts of which are amongst the fastest warming on the planet, with dramatic increase of icesheet loss and other indicators that the continent is indeed impacted by global warming) combined with willful ignorance of why what has been happening there is different to the Arctic isn’t going to help.

    Loss of icesheets, glacial retreat, reduced NH snow cover, ocean heat content rise, sea level rise, global surface temperature rise, increased incidence of extreme weather events… pretty much every measure and indicator there is…. willful ignorance is about all you have to rely on to maintain your illusions about the state of the climate.

  3. janama:”they’ve been going on and on about this for years and predicting an ice free Arctic summer yet it hasn’t eventuated.”

    You are either lying or stunningly ignorant. Your statement is false, and I challenge you to cite one prediction by a climate scientist predicting an ice free summer arctic by now. You won’t find it. Last time I checked the mainstream models put that out around 2030-2050.

    So you are somehow trying to claim that predictions that there will be summertime ice free north polar oceans occurring sometime in the future must be wrong because it hasn’t happened yet!!

    Sheesh.

  4. Janama,
    People have gone on about how rapidly Arctic ice is disappearing; no one expected it to be gone. The models said we might start seeing this by 2030, instead it’s happening now–there are some (but by no means all) who say we may be effectively ice free by 2016–if so, that would be decades ahead of projections. In terms of winter extents–as long as the winter gets cold enough of the water to freeze, we will get ice–since most of the Arctic gets sufficiently cold (even with global warming), we would expect the ocean to freeze over in the winter.
