    As sea ice shrinks to record lows, Prof Peter Wadhams warns a 'global disaster' is now unfolding in northern latitudes.

    I really, really hope he is wrong.

    But, but... that eminent scientist Rush Limbaugh has been assuring his listeners for years that global warming is a hoax, a conspiracy between liberal climatologists evil left-wing politicians. So *I* for one know that this is just more of that fraud, and if that Professor's misplaced some Arctic ice, he can just borrow some from the South Pole, there's plenty to go around. Because Rush told me so. icon_biggrin.gif

    Well.. I'm sure we have it coming sometime or another.

    These people have been predicting disasters for years. Why doesn't any of these predictions come true? Sooner or later you gotta start wondering.

    c'mon people lets grab some polar ice and make margaritas with it.

    it's all over on 122112 anyway....

    How I read the OPs article is that this has less to do with sea level rise and more to do with weather events because...

    http://www.arctic.noaa.gov/faq.html#10
    "The North Pole is in the middle of the Arctic Ocean. Ice on the ocean is already floating, so if the North Pole ice cap melts it has no effect on sea level. It would take melting ice on land (Greenland and Antarctic glaciers) to raise sea level"

    &

    http://www.fastcoexist.com/1678611/how-long-can-greenlands-ice-cap-survive
    "Recent measurements show that there's enough ice in Greenland to build a symmetrical cube measuring roughly 90 miles on a side. It could fill nearly 700,000 cubic miles of volume-space and it covers an area three times the size of Texas. Even with huge torrents of meltwater running into the sea each year, it would take a long time to lose that much ice entirely.

    Computer simulations of complex deglacial melting and surging processes are still too primitive to be very reliable, but even the extreme projections require many centuries to do the deed. Most scenarios stretch the thaw over several millennia, depending on how warm it gets; some take as much as 20,000 years.
    "

    So while coastal flooding might become a problem worth considering and some low lying islands might be in eminent danger, losing Florida probably isn't on the map as fun as it might be to see that scenerio. I have relocated my bamboo plants from just 6 ft above sea level to about 50 ft up, further north in the state, just in case.

    The real problem now seems to be an unknown, how will this effect future weather. For all we know, it just might make more ice someplace else...

    As the sea ice continues to decline, the jet stream will likely continue to slow more, and shift further north “bringing wild temperature swings and greater numbers of extreme events” in the future he said. “We’re in uncharted territory.”
