Scientists are warning that the West Antarctic ice sheet could collapse, potentially causing sea levels to rise more than 49 feet by 2500.
The study published in the journal Nature this week, cites the impact of greenhouse gas emissions over the coming decades. Collapsing Antarctic ice could cause sea levels to rise more than 3 feet by 2100, say co-authors Rob DeConto, a geoscientist at the University of Massachusetts Amherst and David Pollard, a palaeoclimatologist at Pennsylvania State University in University Park.
If emissions continue unabated, the scientists warn, atmospheric warming will soon become a “dominant driver” of ice loss, with prolonged ocean warming delaying its recovery for thousands of years.

For those who have poor reading skills, that means “in places” (turns out, it’s “most of”) the WAIS is already below sealevel; if it melts, in entire, which no actual scientist claims will happen, or had already happened during the previous interglacial, the sealevel rise would be — worst case, which appears to be a gross exaggeration — 3.3 meters.
Monkeys could fly from my butt.
UF could be competitive in a bowl game...
One of the main objections to your analysis would be that your key paragraph-— the one beginning with the words “The constellation Virgo, the Virgin, has always been identified...”-— is bunk.
You are right...
That is a lot of extra water from one tiny already submerged ice shelf....(already submerged means it doesn;t contribute mroe when melted)
And Danica Patrick could win a NASCAR race.
Well that does it then; I’m moving off the planet.
And the Detroit Lions COULD win the Super Bowl.

Now that is REALLY unlikely.
St Louis is 600+ feet above sea level. I’m not worried.
Hey now, I’m giving McElwain another year.
NEWS FLASH!!!!!
ISIS is today planning to go the western Antartic and jump up and down on the icepack to bring flooding to the world!!!!!
I wonder which of the undersea volcanos they discovered recently is getting more active.
Why back when, at a time real science still existed, I recall reading that IF 100% of all glacial ice were to melt, and all land masses were flat, the rise in global sea levels would cover the land in something on the order of 2 inches of water.
A rise of 2,500 feet isn't possible.
My preserved head in a jar is going to be very concerned.
Before 2500?....................maybe.....................
The Antarctic is land with ice and snow atop it as well as ice extending out from shore. Where is the ice on land going to collapse into and what immeasurably tremendous force is going to make it move horizontally for hundreds of miles past the ice over the water?
If not the ice over land, but the water, the ice weight and volume is already displacing the water not frozen reflected throughout the worlds ocean levels.
Or.. they think we're stupid.
By the way.. your math is right on.

17” rise if every glacier on earth completely melted.
