Paris (AFP) - Sea levels around Antarctica have been rising a third faster than the global average, a clear sign of high meltwater runoff from the continent's icesheet, scientists said on Sunday.
Satellite data from 1992 to 2011 found the sea surface around Antarctica's coast rose by around eight centimetres (3.2 inches) in total compared to a rise of six cm for the average of the world's oceans, they said.
The local increase is accompanied by a fall in salinity at the sea surface, as detected by research ships.
These dramatic changes can only be explained by an influx of freshwater from melting ice, warned the study.
Freshwater is less dense than salt water, and so in regions where an excess of freshwater has accumulated, we expect a localised rise in sea level," said Craig Rye from Britain's National Oceanography Centre, who led the probe.
The estimate of ice loss and the precise source of it are hard to pin down, though.
According to the team's computer model, around 350 billion tonnes a year of freshwater influx, plus or minus 100 billion tonnes, would explain the rise.
This estimate puts together freshwater from the ground-based icesheet and also from the thinning of ice shelves -- floating ice that is attached to the coast and created by glaciers disgorging from the icesheet.

and to all those who keep FR afloat..
WE Thank You!!
Icesheet break-up haPPens.. I reckun.
For those of you who wonder why the water doesn’t just flow away to other parts of the vast ocean, it’s obvious. Antarctica is at the bottom of the globe. Water flows down hill. Duh!
Yes but there is great benefits to rising seal levels: It will flood and destroy the liberal cesspools of the east coast like NYC, Boston and flood San Fran on the West, so whut is the problem?
“Freshwater is less dense than salt water, and so in regions where an excess of freshwater has accumulated, we expect a localised rise in sea level,” said Craig Rye from Britain’s National Oceanography Centre, who led the probe.”
So the water only gets deeper where there is no way for independent verification? I hate when I’m filling the tub and I have to keep bailing water down to the other end (where the spigot isn’t filling it).../s
Another FReeper used that example a while ago; why would some places see water levels rise while others didn’t?
I have a cup of water with an ice cube in it. I leave it alone overnight. I come back in the morning.
Q: Will the water flow over the cup?
Maybe sea levels are rising at a 1/3 lower rate everywhere else.
Do you realize that the Earth is spinning at 1,040mph?! How does that water (ice or no ice) stay in the glass?!!
/s
No mention of the volcano underneath the Antarctic ice sheet?
Or not. We really have no way of knowing for sure. All we know is that we have to find some way of getting the peasants to commit economic suicide so the oligarchy can live in the Walden paradise it deserves.
No.
How the hell do these people sleep at night with so much to worry about?
NO, the water will pile up where the ice cube was.
(A)Ice melts... evaporates.. falls as snow again.. compacts..
(B) go to “A”..
“Antarctic sea ice grows to greatest extent EVER even as MSM ramps up its desperate attempts to convince us otherwise”

I ask my lib friends that question all the time. Usually ends with them calling me a racist.
When the ice cube melts what was once ice will occupy the volume if water that was displaced by the floating ice cube to begin with. The part of the cube that was above the surface of the water will not cause an overflow. Another point is that an ice cube (or an iceberg) will float higher in saltwater than fresh water.
No, but the water will be deeper where the ice cube was. /s
You obviously just don’t understand how global warming works.
The water piles up, so that the water level where the ice was is higher than the water that was there before.
Your grant funding is therefore denied.
