John Cook Says Record Antarctic Ice Is Due To Warmer Southern Ocean

According to John Cook, Antarctic sea ice has been expanding because the Southern Ocean is getting warmer. He also claims that anyone thinking more ice is due to colder conditions is “ignorant”.

 

He forgets that some of us know how to check the data.

Bob Tisdale produces analyses of sea surface temperatures each month, and these have shown that the Southern Ocean has been getting considerable colder since 1981, and particularly in the last 8 years.

    Paul, the NODC’s ARGO era depth-averaged temperature data to the depths of 2000 meters also show much of the Southern Ocean cooling:

    The graph is from this recent post:

    Cheers

    John Cook is a lying liar and if he ever caught himself telling the truth he would lie by reflex. That plus he is a scientific fool who is unaware of just how ludicrous he is.

    His little team of hobgoblins over at SkS are so up themselves that any dissent is instantly attacked by any and all means possible and his teaming up with Lewandowsky just exposes the political nature of their activities.

    Yes John, increasing sea ice is a function of Global Warming. Sure it is. Palooka.

    Watts Up With That’s ignorance regarding Antarctic sea ice

    I wonder what he thinks now and if someone has pointed it out to him.

      They don’t like Bob over there. They will pursue their Lilliputian game plan of trying to tie the argument down with a thousand silken threads.

    I tried a couple of times to spend some time on cook’s website and in the end I decided they acted exactly the same as the SS did in nazi time Germany. He is a real current day Goebbels. He only shows/allows what he wants to show and he censors/cuts anything that you write that he does not like.

    I don’t recall ever clicking on the SkS/John Cook site, and likely won’t. But …

    In the Great State of Pennsylvania (western part where I was raised) there is a State Forest named after John Cook, a large land owner of the middle 1800s. Via marriage there seems to be a connection to my family but in the hills and hollows of the Appalachians such things have an uncertainty about them. Makes me wonder, though.

    @Bob Tisdale

    I probably don’t have to tell you: we are globally cooling from the top latitudes downward:

    (average of 10 weatherstations in Alaska= -0.055K/annum since 1998)

    meaning, we have noticeable and measurable cooling at the top latitudes.

    Due to the increasing temp differential between the equator and the poles, you get more clouds and precipitation on the lower latitudes. Hence, you will not notice that much difference as yet here, due to increased condensation energy coming free.

    Cook refers to an article at WUWT. This shows air temperature over Antarctica and quotes Hansen (1984), specifically referring to “warming of air temperature”. It also quotes air temperatures from Vostok.

    The statement “sea ice extent has been increasing over time around Antarctica – this is consistent with the idea that temperatures are cooling”, is taken as a reference to air, not sea surface temperatures (SST).

    Cook’s reply is misleading. He says “the Southern Ocean surrounding Antarctica has shown strong warming over the same period that sea ice has been increasing”. However, Cook’s chart shows air temperatures ‘over ice-covered areas of the Southern Ocean’; not SST.

    In fact, Antarctic SST decreased and sea ice expanded during a period when air temperatures (land and sea) warmed. Land ice has decreased over the same period, but mostly from the base of ice shelves (IPCC, 2013).

      Cook regularly misleads.

      I’m amazed anybody takes him seriously.

      BTW It is well known that when sea ice freezes, the temperature of the air above it increases.

    That might help explain the slight increase in air temperature above the seas around Antarctica during the last 10 – 12 years, but not the more pronounced increase above its land mass.

    @Paul
    On the RSS
    it seems we only have -60 to -70? It that the furthest down it goes?

    • October 19, 2014 1:07 pm

      Yes, as I understand it, the high average height of Antarctica makes measurements dodgy, so RSS have decided to exclude below 70S.

    Reblogged this on Globalcooler's Weblog and commented:
    You couldn’t make this up if you tried. Typical of warmist claims, it’s usually the opposite. I keep thinking maybe this time but no. Tornado variation responsible for decrease Warming responsible for Australian frosts.

    There is some interplay here. See perhaps “Climate of Extremes” by Virginia State Climatologist Patrick J. Michaels. If the air in the Antarctic region is warmer, it stokes the storm clouds and produces more rain and snow. And after a couple years the heaps of unmelted snow that fell on Antarctica become ice. The same way increased levels of CO2 in the temperate regions produce more trees that need CO2 to grow. But the effect of small amounts of temperature change are increasing ice and snow, not massive melting. That is, the global system is self-balancing. It’s darn hard to produce a run-away heat wave.

      The Earth is remarkably resilient in that respect.

      If it was not, we would have had runaway burn out or freeze out many times in the past.

    John Cook simply does not look at real data. That’s why he keeps getting it wrong. I’m just amazed the guy has not yet faced any disciplinary action over some of the rubbish he trumpets!
