I know the ice shelves around the edges of Antartica are melting. But, are the itnerior ice flows actually getting much deeper?

People hear that global warming is causing a few glaciers to retreat, and so just assume that all ice, everywhere, must be melting.
Well, they'll be very surprised to hear that they're wrong.
Have a read of this...

For those who can't be bothered to read the above, here's a quote...
***********
Most researchers are agreed that the West Antarctic Ice Sheet has been retreating over the last 10,000 years, but the new findings, published in the journal Science, could be evidence that that this trend is about to be reversed.
Dr Ian Joughin, of the American space agency's (Nasa) Jet Propulsion Laboratory, and Slawed Tulaczyk, of the University of California at Santa Cruz, say they have found "strong evidence" that the ice sheet in the Ross Sea area is growing, by 26.8 gigatons per year.
Most of the growth is on an ice sheet called ice Stream C.
"The ice sheet has been retreating for the last few thousand years, but we think the end of this retreat has come," says Dr Joughin.
*************
So, yes indeed, the ice in Antarctica is growing, reversing a several-thousand year trend.
:::edit:::
Actually, I've just been reading the UN's (IPCC) "Summary for Policymakers" of their "Fourth Assessment Report", and it states...
Antarctic sea ice extent continues to show inter-annual variability and localized changes but no statistically significant average trends, consistent with the lack of warming reflected in atmospheric temperatures averaged across the region.
In other words; the Antarctic is *not* melting.
Given that, historically, the IPCC have always exaggerated how bad global warming is, we can probably assume that the above actually translates to; the Antarctic is getting colder.

No,its not getting thicker , Infact the ice which is present at the deep inside parts of Antarctica are also melting because of The global warming , it is changing the face of the earth..scientists estimate that in this century the melting of ice will raise the sea level about 30-48 meters...and the temperature is expected to raise about 4.5*C ..the worst is in between South America and Antarctica where avg temp is increased this century to 7*C than normal...so this means the earth would end sooner than we think....

It's really sad that the people who say "No" have no evidence to back up their claims, and the one person who said "yes" DOES have reputable evidence.
Kind of tells you all you need to know about the environmental religion. It's all based on faith.

it's melting from the inside aswell as out,
so no, i don't think it's getting thicker, because then it wouldn't be melting.

according to the DVD...INCONVENIENT TRUTH, by Al Gore and scientists that presented their findings.....NO..it is getting very much thinner at an alarming rate...........(Must see.....DVD)...
