NSIDC : Summer Weather Doesn’t Affect Arctic Melt

August 28, 2012

“The ice is just thinner than it used to be. So it doesn’t really matter so much what the summer weather does anymore—the thin ice melts out easier during the summer melt season.”

Apparently the cold weather this summer had nothing to do with the doubling of Arctic ice!

In a new study, detailed recently in the journal Geophysical Research Letters, Stroeve and her colleagues analyzed nearly two dozen computer climate models to determine the extent to which global warming is responsible for the increasing shrinkage of Arctic sea ice.

Her team determined that human activity can be blamed for some 60 percent of the observed rate of decline since 1979, with the rest due to natural climate variability.

Arctic Sea Ice Hits Record Low—Extreme Weather to Come?

    A pattern is emerging. It’s the “Hillary” defense:

    “it doesn’t really matter … … anymore.”

  2. Andy DC says:

    Humans are 60% to blame for no warming.

  3. CJ says:

    Does that mean humans are responsible for 60% of the increase???

  4. CJ says:

    and……what do the models say this year. ‘Pay no attention to that ice behind the curtain!’

    lol they think its day after tomorrow !!!

    All of that is still better than what I saw (at least) one commenter on Neven’s blog saying…he/she was claiming that this year’s ice was actually in the worst shape of any year yet and was just really spread out so the extent metrics didn’t show it. Others were arguing that they should come up with their own metric since they no longer trusted the various agencies’ area metrics.

      They are right about not trusting any agency’s metric for measuring the ice! All they have is Computer generated graphics and a program that measures pixel concentration of what it thinks is ice. They have land masks to isolate the sea ice from the land ice. They would do as well reading Chicken Bones!

    Chukchi full of ice and not a part of the record. How much 15% do you need?!

    Maybe it’s time they stop playing with models, and start speaking with geologists.

  9. Dave in Canmore says:

    Are they being paid to be comedians or Arctic experts? I can’t tell with statements like this! 60%? Really? How exactly is this verified? What horsefeathers!

  10. Arctic summer temperatures in recent years have not been warmer than normal anyway.

    The ice was melting because it was thin, and not because higher temperatures.

    I will not let this matter go until someone does story on how all the Ice Breaking Ships are destroying the Ice and the Russians Nuk powered Fleet is huge cause . Giant ice breaking ships that are crushing the Ice have increased while at the same time the Ice has decreased. This summer is an exception because it was coldest on record.
    Come on Steve, do you not see the connection.
    Thanks Chris

    One more from the other day,

    It’s fine to talk about the arctic ice and its variations. Some aspect of it is warmer currents. Most of the world’s ice is in the Antarctic. A study of the area in which the well know
    ‘warmer’ Michael Mann participated did note that even after adjustments and extrapolations were made to the satellite data by his group, they concluded that the eastern antarctic, which comtains between 75-85% of the Antarctic ice, had cooled approximately .2C on average each decade since 1979. Observers suggest that the eastern sea ice is more extensive than it has been in decades. One recent warmer suggested that this was because the eastern land ice was melting and running into the sea making it colder, thus freezing and making more sea ice. The warmer did not explain how as it got colder more of the eastern antarctic ice melted. Warmers do contend that the eastern anarctic is thinner than it was. No information or theory was given why getting colder by about .7C might have led to this. We really do not know why the phenomenon claimed by warmers seems only to affect the northern hemisphere, why the predicted equatorial hot spot seems to have eluded us, nor why temperatures have remained flat for a decade and a half. We would do well to recognize the limited understanding we have about our climate and continue to learn rather than give in to man’s apparently inherent utter fascination with apocalyptic scenarios.
