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.

No worries, the world will be bankrupt, people will riot, the muslims will launch nuke strikes, the world will be over by 2500.
The entire continent of Antarctica comprises 14,000,000 km squared, or 1.4x107 km2. The area of the earth's salt water (all seas, oceans, bays, and so forth, taken together) is approximately 3.8x108km2 (numbers are from Wikipedia and so not authoritative, but probably in the ballpark).
So to keep my units the same I converted 49 feet to meters (it's 14.935m) and then to kilometers (1.4935x10-2 km). I then figured out the volume required to add this number to the world's sea levels (assuming the boundaries of the salt water remain the same, which is intensely conservative) and arrived at:
3.6x108km2 x 1.4935x10-2 km = 5.3766x106 km3.
...that is to say, 5.3 million cubic kilometers.
If we were to assume, then, that this much water were evenly distributed over the area of ALL of Antarctica, then the height of it would be 5.3766x106 km3 divided by 1.4x107 km2 (the area of Antarctica), or 0.384 km, or 384 meters.
So the ice all over Antarctica would have to be four football fields deep, and all of it would have to melt in order to do what they say.
These numbers are not out of reason. The premise may be false, but the numbers are reasonable given the premise.
more lies and propaganda; west antarctic ice is melting due to volcanic heat:
How many yards of dirt do I need to fill my 8ft square garden 15 inches deep?
Fixed.
You need 80 cubic feet of soil, or just under three yards. :D
That is sort of what I came up with but the other figures
don’t agree. Anyway an inch a year would be easily measurable
I would think.
GMTA - see post 85.
If I don’t change my ways, I potentially will die as soon as 2500.
lol...I love the alarmist tone here. Even IF it happens it's going to be slow and gradual. Do they really believe that people are going to keep building in the sea as they notice the water is rising?
Hmm,... thanks,.
Nope, ain't happening."
If it does though, just think of the new beach front real estate opportunities!
I wonder if this is the reason for the push by liberals to discontinue the study of algebra in high school?
“The solutions are to prosecute people who don’t believe in global warming, and to tax people so that lots of dollars can be used to stop the rise of the oceans.”
Just build desalination plants all over the globe. Fresh water will end poverty as the left claims while at the same time it will prevent the oceans from rising. Use the money that goes to the UN to fund the projects.
In the year 2525, if man is still alive
If woman can survive, they may find
In the year 3535
Ain’t gonna need to tell the truth, tell no lie
Everything you think, do and say
Is in the pill you took today
thanks
The Ice is already floating so any sea rise has already happened
There’s always an Anartic Ice Sheet, or a Corillian Death Ray, or an intergalactic plague that is about to wipe out all life on this miserable little planet, and the only way these people can get on with their happy lives is that they DO NOT KNOW ABOUT IT!
