As ice melts away from Antarctica, parts of the continental bedrock are rising in response -- and other parts are sinking, scientists have discovered.

Before POLENET and its more spatially limited predecessors, scientists had few direct measurements of the bedrock. They had to rely on computer models, which now appear to be incorrect.
"When you compare how fast the earth is rising, and where, to the models of where ice is being lost and how much is lost -- they don't match," Wilson said. "There are places where the models predict no crustal uplift, where we see several millimeters of uplift per year. We even have evidence of other places sinking, which is not predicted by any of the models."

"We're pinning down both parts of this problem, which will improve the correction made to the satellite data, which will in turn improve what we know about whether we're gaining ice or losing ice," Wilson said. Better estimates of sea level rise can then follow.

There is something about a complex system responding to stimuli that science morons like algore don’t comprehend.
Oh wait! When these scientist discover their funds have dried up they will come around and praise AlGore.
It appears that the past decade of media hype about the Antarctic melting may or may not be true, depending on what these new and improved methods tell us. Meanwhile, we proceed to alter the entire global economy based on what may or may not be a correct assumption. Perfect. /s/
“help improve estimates of future sea level rise”
So here’s is what we want to happen doggone it.
THE SEA SHALL RISE
We know it will, we’re staking our funding on it.
I cry BS! Antarctic ice has been increasing in recent decades and Arctic ice is up from the last 5 years. They’ve been doing more “adjusting” of the data to fit their agendas again.
Actually, even the global warming alarmists acknowledge that the Antarctic has been gaining ice. It is truly amazing how a"journalist" can write this story and miss this point. He is either dumber than a rock, or he is intentionally misleading his readers. Neither option is good.
Within the last few weeks I noticed an article about the use of satellite-derived data that implied Greenland was losing ice at a rapid rate, or at least we were confidently told that as a peer-reviewed fact.
Now comes this week's confident news that if we just could understand how we are misunderstanding this stunningly important anomaly in the data that we could know “whether we're gaining ice or losing ice”.
This news that seems to contradict the previous news shares one thing in common: how confident these scientists are that it still will confirm AGW.
"POLENET is funded by the National Science Foundation."
"*Wilson reported the research in a press conference December 15, 2008 at the American Geophysical Union meeting in San Francisco."
The article in no way said that ice melting (or even that it was melting) had anything to do with moving plate. Agenda? You betcha!!
Most of the warming hype I’ve seen for Antarctica centers on ice shelves on the Antarctic Peninsula, which extends fairly far north. Larsen A and Larsen B near the tip collapsed, the latter in 2002, I think, and last year the Wilkes ice shelf on the other side and further south came within a whisker. Larsen A actually started to re-form, and lasted through the last summer season, but it looks fragile this year and I don’t know if it’ll make through February. If it goes again, they’ll be kind of hard put to make much of it.
Anyway, I haven’t noticed anything about any actual reduction in the southern polar ice sheets. I kind of keep track visually for myself with the MODIS images, and the perimeter of Antarctica doesn’t show the same vulnerability that you see in southern Greenland, where the summer weather seems to gnaw at the edges.
BTW, the sea ice near McMurdo is very extensive this new summer season, with “fast ice” ( “fast” to the shore line ) extends well into the Ross Sea, seaward of McMurdo Sound proper. A few years ago, 2005 I think, there was the episode of the B-15 iceberg, which had calved off the Ross Ice Shelf and was the size of Long Island, nestled up against McMurdo Sound. The ice was late to break up and they blamed B-15 for that and all kinds of other things. If this “fast ice” lasts into January, they’re going to have to come up with something.
This is nothing more than plain, ole isostatic rebound, known for many years to occur in the crust whenever glacial ice melts. It's been measured in Scandinavia and Canada for years.
In fact, I've often wondered why the globul warming libtards never mention it, as it would effectively cancel out any coastal flooding that might occur, if globull warming actually did happen the way they say.
Gorbull warming editorial comment:
The finding will give much needed perspective to satellite instruments that measure ice loss on the continent, and help improve estimates of future sea level rise.
Now the (immediately following) actual, unprejudiced quotation from a real scientist:
"Our preliminary results show that we can dramatically improve our estimates of whether Antarctica is gaining or losing ice," said Terry Wilson,* associate professor of earth sciences at Ohio State University.
The dammedia simply cannot resist putting their liberal. biased spin on this issue -- even if it it is printed right adjacent to a proper, unprejudiced, quoted scientific statement that contradicts it!
The problem with this theory is that the ice is actually greater on this date compared to the 1979-2000 mean when they started recording the satellite data:

Here is the actual area since 1979:

As summer begins here is the actual situation as of today:

BTW total sea ice is just about at the mean since 1979:

Gives one a lot of confidence in those who rely on computer models.
One thing they never explain is how ice melts in 50 to 100 degrees below zero temperatures.

Fire Under Arctic Ice: Volcanoes Have Been Blowing Their Tops In The Deep Ocean
ScienceDaily (June 26, 2008) A research team led by the Woods Hole Oceanographic Institution (WHOI) has uncovered evidence of explosive volcanic eruptions deep beneath the ice-covered surface of the Arctic Ocean. Such violent eruptions of splintered, fragmented rock—known as pyroclastic deposits — were not thought possible at great ocean depths because of the intense weight and pressure of water and because of the composition of seafloor magma and rock...

BINGO.
In real life, Ceterus Paribus does not exist.
