Long-lost Greenland ice core suggests potential for disastrous sea level rise

A mile-thick ice sheet in Greenland vanished around 416,000 years ago during a period of moderate natural warming, driving global sea rise to levels that would spell catastrophe for coastal regions today, a study said Thursday. The results overturn a long-held view that the world's largest island was an impregnable fortress of ice over the past 2.5 million years and instead show it will be far more vulnerable to human-caused climate change than previously thought. "If we want to understand the future, we need to understand the past," University of Vermont scientist Paul Bierman, who co-led the paper published in Science, told AFP Scientists were stunned to learn it contained not just sediment but leaves and moss – irrefutable evidence of an ice-free landscape, perhaps covered by an ancient forest that woolly mammoths would have roamed. If Greenland’s ice sheet saw rapid melting during a period of moderate warming, it may be more sensitive to human-caused climate change than previously understood – and will be vulnerable to irreversible, rapid melting in coming centuries.

      loosing permafrost over a long period will prove fatal at some point

        Permafrost melting also releases massive amounts of methane which exacerbates atmospheric warming...a vicious circle

        We could be setting ourselves up for a disastrous future.
