Satellites say Southern hemisphere sea ice area is at a record area again

Day 110 of 2014 just snuck into record territory again according to graphic at The Cryosphere Today

    More interesting is how far SH sea ice is over the 2 standard deviations line. Looks to be over 3 standard deviations above the average, which make the odds of this being chance (natural variation) very small, in the range of hundreds to one against.

    The repeated claims of a ‘slight increase’ in Antarctic sea ice, are particularly dishonest, even by the standards of climate science.

    It’s all now an outright scam, Mann:

    I don’t understand something so am looking for an explanation..

    Sth ice is up at record levels whereas Nth extent is down (not at lowest but low).

    WUWT site shows latest global trends and Sth hemisphere is warmer and nth is colder – both significantly yet poles are opposite to their respective hemispheres???


  • Think of the polar bears guys!

    Just add a boatload of rent seeking greenies & stir gently!

  • Re: ‘M’
    Your observations reminded me of a graph l have in my archives

    Some sort of Bi-polar see saw ?

    Maybe related to the thermohaline ocean conveyor belt (THC)that changes strength during its cycle

    Probably nobody actually knows whatever you are told.

    after all we were told Greenland could lose all its ice,

    M, Reduced clouds combined with sea ice albedo, explains the hemispheric difference, as well as the summer winter difference in both hemispheres..

    The ‘loss’ of NH sea ice is mostly downwind of the Kola Peninsula, where > 90% of the entire Arctic population live and and it used to be (and to a large extent still is) packed with very polluting Soviet era industry and infrastructure.

    Black carbon gets deposited on the ice and aerosols seed clouds. Reduce both simultaneously which is what happened around the time of the 1998 Russian Financial Crisis, and you have more solar insolation shining on sea ice with embedded black carbon, which melts. Hence the very low NH summer sea ice minimums around that time.

    Studiously ignored by the climate science community was at that time we saw record NH summer lows, we also saw record NH sea ice formation from summer minimum extent to winter maximum extent. Hence, NH sea ice loss was purely a melt season phenomena. Directly, opposite to what GHG warming predicts.

    In the SH at sea ice latitudes, black carbon and anthropogenic aerosols are almost non-existent. Hence, it is where we will see any global trend, and that trend is increasing ice caused by globally decreasing clouds, especially low level clouds.Don’t know where you got NH and SH temperatures from, but be aware surface temperature measurements aren’t worth much.

    And one alarmist I tangled with claims … “but ice volume is decreasing”. (who, exactly, is measuring ice volume, and does it even make sense that volume is decreasing at the same time sea ice extent is growing?

    M – if you check the monthly satellite data at these two links you will see a cool anomaly for March in the Antarctic. You can also see the north polar region has been warming for 35 years while the south polar region shows no trend.
    RSS data – makes charts online – change the region on the right
    UAH data – download last file
    The RSS south polar region is 70South to 60South while the UAH south polar region is 85South to 60South

    Arctic sea ice volume has decreased faster than extent in recent years, because older thicker ice is melting faster (and by a large margin) than newer ice.

    Atmospheric or ocean temperatures could not cause this. The cause is, older ice has higher levels of embedded black carbon, as stated above.

  • OMG! At the current rate of ~0.9 million km²/week, the ice shelf will reach Tasmania by 2016!

    This requires LOTS of urgent research funding to investigate. ;-)

    Imagine what we would be hearing from “the warmist industry” if the trend was the other way.

    Philip your theory is interesting but i cant find any references or material that supports it on the web. is it made up or is there something that supports it

    also jaxa sea ice shows that winter maxima are lower than they were before so it cant just be a melt season summer “phenomena” can it?

    and isn’t the most of the old sea ice that melts only 2 to 4 years old?

  • Accounts of southern hemisphere ice bergs sighted from sailing ships late 19C.
    Imagine if those events happened now.
    It would cause mass media hysteria for sure.
