The study predicts that what remains of the once-prominent ice shelf, a thick floating platform of ice, most likely will "disintegrate completely" before the end of this decade
It's possible. I'm going from memory so it's possible that further data has changed the times when sea levels reached their current level. Either way, it's 2,000 years difference, which geologically is nothing.
Either way, you were wrong.
Possibly. The graph you posted is from a AGW group so their info is a tad biased don't you think?
If you have evidence that it is wrong, by all means, put it up. Otherwise, admit that you were mistaken and move on.
I already did. I said I could be 2000 years off. I haven't kept track of sea level research in 30 years. I am sure that they have refined their figures. I am having a hard time coming up with the original studies that generated that graph though.
Do you have a link to one of them?
Sure. Five bucks:

By the way, even 8,000 years ago sea levels was 20 meters lower than they are today. So you weren't just off, you were completely wrong.

ALL THE TIME on their predictions. There are many threads in this forum that document the scores of fake/fail predictions by these bozo's.

It will do zero to sea levels. For Christsakes Dims are fucking stupid.
So, the fact that the shelf is only 10,000 years old escaped your attention did it? If the shelf is only 10,000 years old, that means that it was a whole bunch warmer before that. Then it got cold. What "magic" is responsible for that?
The age of the shelf is unimportant. What is important is what it's disintegration is going to do to global sea levels, how it will impact coastlines full of people.

A new NASA study finds the last remaining section of Antarctica's Larsen B Ice Shelf, which partially collapsed in 2002, is quickly weakening and likely to disintegrate completely before the end of the decade.
A team led by Ala Khazendar of NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, found the remnant of the Larsen B Ice Shelf is flowing faster, becoming increasingly fragmented and developing large cracks. Two of its tributary glaciers also are flowing faster and thinning rapidly.
"These are warning signs that the remnant is disintegrating," Khazendar said. "Although it’s fascinating scientifically to have a front-row seat to watch the ice shelf becoming unstable and breaking up, it’s bad news for our planet. This ice shelf has existed for at least 10,000 years, and soon it will be gone."
Ice shelves are the gatekeepers for glaciers flowing from Antarctica toward the ocean. Without them, glacial ice enters the ocean faster and accelerates the pace of global sea level rise. This study, the first to look comprehensively at the health of the Larsen B remnant and the glaciers that flow into it, has been published online in the journal Earth and Planetary Science Letters.
Khazendar's team used data on ice surface elevations and bedrock depths from instrumented aircraft participating in NASA's Operation IceBridge, a multiyear airborne survey campaign that provides unprecedented documentation annually of Antarctica's glaciers, ice shelves and ice sheets. Data on flow speeds came from spaceborne synthetic aperture radars operating since 1997.
Khazendar noted his estimate of the remnant's remaining life span was based on the likely scenario that a huge, widening rift that has formed near the ice shelf's grounding line will eventually crack all the way across. The free-floating remnant will shatter into hundreds of icebergs that will drift away, and the glaciers will rev up for their unhindered move to the sea.
Located on the coast of the Antarctic Peninsula, the Larsen B remnant is about 625 square miles (1,600 square kilometers) in area and about 1,640 feet (500 meters) thick at its thickest point. Its three major tributary glaciers are fed by their own tributaries farther inland.
"What is really surprising about Larsen B is how quickly the changes are taking place," Khazendar said. "Change has been relentless."
The remnant's main tributary glaciers are named Leppard, Flask and Starbuck -- the latter two after characters in the novel Moby Dick. The glaciers' thicknesses and flow speeds changed only slightly in the first couple of years following the 2002 collapse, leading researchers to assume they remained stable. The new study revealed, however, that Leppard and Flask glaciers have thinned by 65-72 feet (20-22 meters) and accelerated considerably in the intervening years. The fastest-moving part of Flask Glacier had accelerated 36 percent by 2012 to a flow speed of 2,300 feet (700 meters) a year -- comparable to a car accelerating from 55 to 75 mph.
Flask's acceleration, while the remnant has been weakening, may be just a preview of what will happen when the remnant breaks up completely. After the 2002 Larsen B collapse, the glaciers behind the collapsed part of the shelf accelerated as much as eightfold – comparable to a car accelerating from 55 to 440 mph.
The third and smallest glacier, Starbuck, has changed little. Starbuck's channel is narrow compared with those of the other glaciers, and strongly anchored to the bedrock, which, according to authors of the study, explains its comparative stability.
"This study of the Antarctic Peninsula glaciers provides insights about how ice shelves farther south, which hold much more land ice, will react to a warming climate," said JPL glaciologist Eric Rignot, a coauthor of the paper.
The research team included scientists from JPL, the University of California, Irvine, and the University Centre in Svalbard, Norway. The paper is online at:

Like you do when you're proven wrong right?Umm, no, 12,000 years ago you would be correct. 10,000 years ago the Med probably flowed into the Sea of Marmara and flooded the Black sea, that would have been a huge influx, 95 meters or so, but the rest of the world was within a couple of meters of what it is today. The big flood occurred at the 14,000-12,000 year ago mark. Since then the increase has been vastly reduced to where today it is nearly un-measurable.

An ice sheet in water that melts does nothing to the sea level. A melting/collapsing ice sheet on water holding back a massive glacier on land acts like a failing damn, releasing into the ocean the ice locked up on that land glacier. And THAT does affect sea level.

The remnant's main tributary glaciers are named Leppard, Flask and Starbuck -- the latter two after characters in the novel Moby Dick. The glaciers' thicknesses and flow speeds changed only slightly in the first couple of years following the 2002 collapse, leading researchers to assume they remained stable. The new study revealed, however, that Leppard and Flask glaciers have thinned by 65-72 feet (20-22 meters) and accelerated considerably in the intervening years. The fastest-moving part of Flask Glacier had accelerated 36 percent by 2012 to a flow speed of 2,300 feet (700 meters) a year -- comparable to a car accelerating from 55 to 75 mph.
Flask's acceleration, while the remnant has been weakening, may be just a preview of what will happen when the remnant breaks up completely. After the 2002 Larsen B collapse, the glaciers behind the collapsed part of the shelf accelerated as much as eightfold – comparable to a car accelerating from 55 to 440 mph.
The third and smallest glacier, Starbuck, has changed little. Starbuck's channel is narrow compared with those of the other glaciers, and strongly anchored to the bedrock, which, according to authors of the study, explains its comparative stability.
"This study of the Antarctic Peninsula glaciers provides insights about how ice shelves farther south, which hold much more land ice, will react to a warming climate," said JPL glaciologist Eric Rignot, a coauthor of the paper.
The research team included scientists from JPL, the University of California, Irvine, and the University Centre in Svalbard, Norway. The paper is online at:

Dude....A glacier in water that melts does exactly zero to sea level. Jeezus, if that has to be explained all hope is lost.
An ice sheet in water that melts does nothing to the sea level. A melting/collapsing ice sheet on water holding back a massive glacier on land acts like a failing damn, releasing into the ocean the ice locked up on that land glacier. And THAT does affect sea level.
But it is floating. Big word there. Read what I posted. It's been posted earlier in the thread. Float adds zippolla
