Sunrise 2 days early in Greenland - Climate change to blame

    The sun over Greenland has risen two days early, baffling scientists and sparking fears that Arctic icecaps are melting faster than previously thought.
    Experts say the sun should have risen over the Arctic nation's most westerly town, Ilulissat, yesterday, ending a month-and-a-half of winter darkness.
    But for the first time in history light began creeping over the horizon at around 1pm on Tuesday - 48 hours ahead of the usual date of 13 January.
    The mysterious sunrise has confused scientists, although it is believed the most likely explanation is that it is down to the lower height of melting icecaps allowing the sun's light to penetrate through earlier.

    World Climate Report
    The recent hype in Nature notwithstanding, Greenland has been cooling for the better part of two generations.

    It’s hot news: Temperatures in Greenland have been rising like a rocket during the past 10 years or so—returning to the temperatures that characterized the 1930s, ’40s, and ’50s.

    Yet that bit of history—that temperatures were as warm or warmer in Greenland 50 years ago—appears lost on the global warming crowd. Instead, they have increasingly pointed a finger at the changing conditions there during the past decade as a clear sign of anthropogenic global warming.

    An article in the March 11, 2004, issue of Nature magazine even goes so far as to suggest that Greenland may be on a path of warming and ice loss from which it can never recover. Apparently, Nature writer Quinn Schiermeier is ignorant of the fact that 70 years ago, a similar temperature rise in Greenland was followed by six decades of cooling—it seems as if it recovered from that warming just fine!

    Its something to do with the pole shift , the dark rift and frequency or harmonics of whatever , i think . Its all explained on utube .

    Any chance you could link the video. Sounds interesting to say the least.

    You'd think they'd be happy!

    Didnt realise the ice caps could be high enough to effect the sun shining on Greenland that much.

    How about the axis of the earth? Is that not factored into this or already been checked?

    There's an interesting piece about it here - http://halfastro.wordpress.com/2011/01/14/greenlands-early-sunrise/

    It may have been a sun-dog caused by ice crystals in the atmosphere. Sounds far more probable than the global warming reason which is being bandied about

    Are you people for real?

    Sunrise and sunsets are due to the angle of the Earth's axis on the ecliptic plane. How can climate change affect this?

    Pure baloney!

    An explanation is that the horizon is lower as the ice has melted.

    Why don't they raise the horizon?
    Awaits multiple awards for solving Global Warming.

    The horizon is the horizon - it can't lower - you cannot deflate the size of the Earth.

    However if you were to follow the CT'er logic (in the loosest possible term of the word) less ice means line of sight has changed,
    - however that would mean apparent altitude to sea level is lower (less ice to stand on)
    - so the horizon should appear closer
    - so that should mean for an observer that the sun should appear to be below the horizon for longer
    - so that should mean that it remain darker for longer.

    eh.. the 'climate change is to blame' theory is not one from the CT'ers, it's one of the possible reasons being put forward by scientists

    Yeah - I read that.
    None of the scientist witnessed it. Only one small town. Ilulissat
    It wasn't seen in Fairbanks.

    "While they disagreed on the cause of the town's early sunrise, experts did reach one consensus: This was an isolated event, not a sign of earlier spring around the Northern Hemisphere."
