   Phil,


   Nothing scary about this. Quite interesting really.


   I have never claimed anyone at UEA has "mis-reported" - even if I thought they had.


   Research paper is at : [1]www.tyndall.ac.uk/publications/working_papers/twp98_summary.shtml
    Submitted for publication.


   Mike

    Mike,
       Not sure if this is the sort of scaremongering reporting you are
    referring to!
       Also not sure who you are referring to as misreporting here at
    UEA. Maybe Dave, but he's not here now!
    Cheers
    Phil

   Analysis Finds Large Antarctic Area Has Melted
   By ANDREW C. REVKIN
   While much of the world has warmed in a pattern that scientists have linked with near
   certainty to human activities, the frigid interior of Antarctica has resisted the trend.
   Now, a new satellite analysis shows that at least once in the last several years, masses of
   unusually warm air pushed to within 310 miles of the South Pole and remained long enough to
   melt surface snow across a California-size expanse.
   The warm spell, which occurred over one week in 2005, was detected by scientists from the
   Jet Propulsion Laboratory of NASA and the University of Colorado, Boulder.
   Balmy air, with a temperature of up to 41 degrees in some places, persisted across three
   broad swathes of West Antarctica long enough to leave a distinctive signature of melting, a
   layer of ice in the snow that cloaks the vast ice sheets of the frozen continent. The layer
   formed the same way a crust of ice can form in a yard in winter when a warm day and then a
   freezing night follow a snowfall, the scientists said.
   The evidence of melting was detected by a National Aeronautics and Space Administration
   satellite, the QuickScat, that uses radar to distinguish between snow and ice as it scans
   the surfaces of Greenland and Antarctica.
   There have been other areas in Antarctica where such melt zones have been seen, but they
   are not common so far inland, said Son Nghiem, a scientist at the NASA laboratory who
   directed the analysis with Konrad Steffen, a glaciologist at the University of Colorado,
   Boulder.
   Some melting also occurred at an elevation of more than 6,000 feet, in regions where
   temperatures usually remain far below freezing year-round.
   It is too soon to know whether the warm spell was a fluke or a portent, Dr. Nghiem said.
   "It is vital we continue monitoring this region to determine if a long-term trend may be
   developing," he said.
   Dr. Steffen said if such conditions intensified or persisted for a long time, the melting
   could conceivably produce streams of water that could, as has been measured in Greenland,
   percolate down to bedrock and allow the thick ice sheets coating the continent to slide a
   bit faster toward the sea.
