Mass balance of the Antarctic ice sheet.
Wingham, D.J., Shepherd, A., Muir, A. and Marshall, G.J.
What was done The authors "analyzed 1.2 x 108 European remote sensing satellite altimeter echoes to determine the changes in volume of the Antarctic ice sheet from 1992 to 2003." This survey, in their words, "covers 85% of the East Antarctic ice sheet and 51% of the West Antarctic ice sheet," which together comprise "72% of the grounded ice sheet.""
What was learned Wingham et al. report that "overall, the data, corrected for isostatic rebound, show the ice sheet growing at 5 ± 1 mm year-1." To calculate the ice sheet's change in mass, however, "requires knowledge of the density at which the volume changes have occurred," and when the researchers' best estimates of regional differences in this parameter are used, they find that "72% of the Antarctic ice sheet is gaining 27 ± 29 Gt year-1, a sink of ocean mass sufficient to lower [authors' italics] global sea levels by 0.08 mm year-1." This net extraction of water from the global ocean, according to Wingham et al., occurs because "mass gains from accumulating snow, particularly on the Antarctic Peninsula and within East Antarctica, exceed the ice dynamic mass loss from West Antarctica."
What it means Contrary to all the horror stories one hears about global warming-induced mass wastage of the Antarctic ice sheet leading to rising sea levels that gobble up coastal lowlands worldwide, the most recent decade of pertinent real-world data suggest that forces leading to just the opposite effect are apparently prevailing, even in the face of what climate alarmists typically describe as the greatest warming of the world in the past two millennia or more.
Algore put some ice on it.
Now they just need to figure out why growing ice sheets will cause the end of life as we know it. Any change cam be made scary.

Ain't THAT the truth..... (roll eyes)
I have long been concerned with global cooling ....we need to study it and do all we can to stop it
So does this mean we will forced to drive even bigger SUV's?
Here's some data to back up this article: NEW FINDINGS SHOW ANTARCTIC COOLING AND ICE CAP EXPANSION
Here's a good index of articles: Dr Dewpoint Category Listing - Global Warming
Billy Bubba spends hundreds on a haircut, but Treebeard won't even spring for Costcutters!
It's OBVIOUSLY the result of Global Warming. Don't you people know anything? < s>
Its been a scientifically proven FACT that the Antartic ice sheet CONTRACTS during years of Republican control of congress, and EXPANDS during years of 'Rat control of congress.
WE'RE DOOMED!
But--but Arnie says California is onboard with the Kyoto treaty. And--and the Dems in congress say they're going to pass all kinds of new regulations to help stop global warming. They can't be wrong can they?
If the Antarctic ice cap is growing then the danger that Einstein was worried about is looming.
Bump.
The ice age is comeing.
(The enviro-socialists have never explained why we don't have an ARCTIC ozone hole.)
They're saving that for when their current bs quits convincing their sheep.
Good lord,
I didn't realize that he'd gotten that fat.
Someone paint Goodyear on the side of him quick.
