Its generally accepted that its no longer a question of whether the West Antarctic Ice Sheet will melt, its a question of when, said Ian Howat, associate professor of earth sciences at Ohio State.
We may see a significant collapse of West Antarctica in our lifetimes.
In 2013, a gigantic rift began forming within a valley in the ice of the Pine Island Glacier.
Then, in 2015, a 225-square-mile iceberg broke off and floated away. Discovered a massive crack across the Pine Island Glacier, in the West Antarctic Ice Sheet. Extending for 19 miles, the crack was 260 feet wide and 195 feet deep.Photo: NASA
Howat said this could indicate that the massive slab of ice was being eaten away from the inside out.
Rifts usually form at the margins of an ice shelf, where the ice is thin and subject to shearing that rips it apart, he added.
However, this latest event in the Pine Island Glacier was due to a rift that originated from the center of the ice shelf and propagated out to the margins.
This implies that something weakened the center of the ice shelf, with the most likely explanation being a crevasse melted out at the bedrock level by a warming ocean.
The ice sheet has previously been described as an awakened giant and is mostly made up of glaciers sitting on top of a layer of bedrock.
If it melts, it would add vast amounts of water into the oceans, sending sea levels rocketing to dangerous heights.
The really troubling thing is that there are many of these valleys further up-glacier, Howat added. If they are actually sites of weakness that are prone to rifting, we could potentially see more accelerated ice loss in Antarctica.

“If it melts, it would add vast amounts of water into the oceans, sending sea levels rocketing to dangerous heights.”
Did the writer graduate from high school? When ice melts water is going from the solid state to the liquid state. Sea levels will not rise one millimeter. In fact, the ocean levels would go down a tiny fraction because water contracts when it goes from solid state to liquid state.
I guess I am not as smart as John Kerry is.
A drought could turn it into a desert.
Well, I'm certainly not an expert either, but I do know (shudders) what sea water tastes like. Tastes like...PEOPLE!!
Promises, promises....
15 I will remember my covenant between me and you and all living creatures of every kind. Never again will the waters become a flood to destroy all life. 16 Whenever the rainbow appears in the clouds, I will see it and remember the everlasting covenant between God and all living creatures of every kind on the earth.
Yes. You see normally when the ocean rises it rises all over the world but with Man Caused Climate Change it will only rise in ONE spot because Gaia is punishing the humans.
The only way to appease her is to send great quantities of money to High Priest AlGore.
NYC is going to be nuked. Hopefully not in my lifetime.
True, but God said that He wouldn't do that again.
When our time is up, we will see the effects of the real Man caused Global Warming.
2 Peter 3:9-13 The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance. But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up. Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness, Looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat? Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness.
You are correct if the water is floating like an ice berg. But this water is a glacier which is on land presently. If the glacier slides in to the ocean it will cause the ocean water level to rise.
Consequently the land on which the glacier resides will also rise (rebound) because of the weight of the water has been lifted off the land. Land elsewhere is likely to fall because this land has risen.
I’d be more worried about that volcano in the Canary Islands area lets go!
so approximately a 7.5 to 8 cubic mile piece of ice(assuming a height to depth 200 feet average with .9 of the ice under water) broke off...since that ice was already floating on the water there would be no positive displacement.
Will the flushing tide reach Albany?
I was given to understand that the ice was floating on water but still attached to the sheet until it got displaced from the ice behind it on land.
“Will the flushing tide reach Albany?”
No, but it will flush out Flushing!
Doooomed! Doomed, I tell ya!
We need amnesty for illegals and common sense gun control to combat this.
I know. I was going to grab the recyclable, even thought, “this could mean the life or death of millions in the coastal regions”, but nooo! I blew it off. Had four family people needing four different things and thought of them.
Doomed. The cashier made me remember. Thank God I have a chance at confession with a promised. I KNOW that cashier will never forgive me. Never
