Arctic Ice Loss Somewhat Natural, Study Says

OSLO (Reuters) - Natural swings in the Arctic climate have caused up to half the precipitous losses of sea ice around the North Pole in recent decades, with the rest driven by man-made global warming, scientists said on Monday.

The study indicates that an ice-free Arctic Ocean, often feared to be just years away, in one of the starkest signs of man-made global warming, could be delayed if nature swings back to a cooler mode.

Natural variations in the Arctic climate "may be responsible for about 30–50 percent of the overall decline in September sea ice since 1979," the U.S.-based team of scientists wrote in the journal Nature Climate Change.

Sea ice has shrunk steadily and hit a record low in September 2012 -- late summer in the Arctic -- in satellite records dating back to 1979.

    "see venus"

    Why look that far when we have an example much closer?

    Earth has spent a lot more time in a hothouse state than our current iceball state.

    Earth has spent a lot more time in a hothouse state than our current iceball state.

    But never in a hellball state as Venus. Not impossible, though.

    Why look that far when we have an example much closer?

    For contrast, buddy.
    Also an example of a equilibrium state that is unable to sustain life (at least not the human one) even if Venus is in the Goldilocks zone.

      Hothouse earth wouldn't exactly support human life either, "buddy."

        I can't figure out what you object to. Is it Venus a bad example?

          Venus just seems like a contrived example, one deliberately removed from Earth.

          Almost as if you are unconsciously shying away from the fact that Earth has had tremendous climate changes many times in the past, without any Humans around to cause them.

            Or not being aware of them, but incidentally knowing the condition in Venus.

            Feel free to put whatever you think as motivation for my choice, free speech is allowed on SN. But don't be surprised if I'll drop the conversation and ignore you when you go to far.

              No need to be offended.

              "Or not being aware of them"

              Perfectly good explanation as well, as far as that goes.

              But either way, surely you can see how it seems interesting to me how often people who lack such basic knowledge on the subject think they are somehow qualified to tell me what to think?

                Heh, yeah... sure, mate.
                It's usually called "Commenting on SoylentNews", not "Publishing in a peer-reviewed science journal" nor "Internet mediated hypno-trace mind washing".
                Glad that you are immune to the latter, but I reckon assuming the worst hidden agenda every time is a bit of an overreaction.
