Hey "My-Socialism-Is-Better-Than-Yours" Fran, my alarmist friend, this
is just one small corner of the WEST Antarctic, and this is OLD NEWS.
We have been hearing this stuff from "scientists" with an agenda for
ages now.
Here is the real news ...

Researchers: Antarctica Ice Sheet Stable

WELLINGTON, New Zealand (AP) - An ice sheet in Antarctica that is the
world's largest - with enough water to raise global sea levels by 200
feet - is relatively stable and poses no immediate threat, according to
new research.
While studies of the Greenland and West Antarctic ice sheets show they
are both at risk from global warming, the East Antarctic ice sheet will
"need quite a bit of warming" to be affected, Andrew Mackintosh, a
senior lecturer at Victoria University, said Wednesday.
The air over the East Antarctic ice sheet, an ice mass more than 1,875
miles across and up to 2.5 miles thick centered on the South Pole, will
remain cold enough to prevent significant melting in the near future,
the New Zealand-led research shows.
But it eventually may become vulnerable to the effects of rising sea
levels driven by the melting of other ice sheets, Mackintosh's team
found. Their research was published this week in the journal Geology.
"The East Antarctic ice sheet is the largest and the coldest and is
going to be the last to respond in any great way" to global warming, he
said. "Our research suggests changes in sea levels due to global warming
will not be caused by changes in the East Antarctic Ice Sheet yet."
The researchers found that from 13,000 to 7,000 years ago, when sea
levels rose by more than 330 feet, the East Antarctic ice sheet thinned
by 660 feet to 1,150 feet. Rising waters during that period would have
lifted the buoyant ice sheet's edges off its rocky base, causing pieces
to detach or "calve" and melt.
If the sheet experienced such calving again, even small changes could
have a significant impact, the researchers said.
The study - conducted with Australia's Macquarie University and the
Australian Nuclear Science & Technology Organization - did not predict
how much sea levels would have to rise before the sheet's edges started
to break away.
Glaciologist Wendy Lawson, head of geography at Canterbury University
who took no part in the study, said the new research supported previous
modeling indicating the sheet was stable.
"There is no short-term risk as far as the overall magnitude of the East
Antarctic ice sheet goes," she said.
