“It’s generally accepted that it’s no longer a question of whether the West Antarctic Ice Sheet will melt, it’s 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.”

Ask God to spare the normal folks this time. Besides, He has promised the fire not the flood next time.

I am merely making an observation ~ if NYC were to be suddenly annihilated, I would lose blood relatives, many friends, and acquaintances - But I could deal with it....
At least it would wash all that sh*t and p*ss that the low T, lowerer IQ liberal mayor has allowed to be placed there by his democrat voters.
Could we manage a two fer with California falling into the ocean?
If it really was of Biblical proportions I’d look for fire and brimstone and people turning into pillars of salt and that sort of thing...
Pretty sure this is ice completely (or mainly) on top of land.
[[New study finds Antarctic ice growing, countering earlier studies
According to the new analysis of satellite data, the Antarctic ice sheet showed a net gain of 112 billion tons of ice a year from 1992 to 2001. That net gain slowed to 82 billion tons of ice per year between 2003 and 2008. The mass gain from the thickening of East Antarctica remained steady from 1992 to 2008 at 200 billion tons per year, while the ice losses from the coastal regions of West Antarctica and the Antarctic Peninsula increased by 65 billion tons per year.]]
And I COULD win a $20 million lottery!
Suffolk County, the eastern HALF of Long Island is red. Trump country.
Oops, lower, not lowerer...although I kind of like the way it matches the progressive mentalitity.
But they’re not talking about floating ice. They’re talking about glacial ice on top of bedrock. They’re still full of crap. Just sayin’
A tiny but powerful alien critter can destroy the planet!
I am quite sure this is my fault. I went to Whole Foods the other day. Got on line to pay without a recyclable bag the cashier said it was my fault that we were all going to be doomed to drowning in a sea of global ice melting. Well, she didn’t SAY it. But it was the body language.
Beach front Vegas! ...
After thinking on it for a few minutes, I’ve decided that we might want to try to warn the good folks at Henry rifles so they have a chance to move their operations. They are currently located in Brooklyn and it would be a shame if their excellent lever-action rifles were no longer available.
I don’t claim to be an expert on these things, but wouldn’t the pillars of salt dissolve in the flood waters?
Interesting theory that a meteor or comet hit polar cap 12,000 years ago which caused great flood. Lot of evidence to back it up. Dovetails with Plato’s timeline of destruction of Atlantis
That's up next, since we were promised no more floods.
Jerk!
Why couldn’t you have thought of someone other than yourself for once in your life?
;-)
So, will that melting be before or after the mini-ice age that is supposed to be coming in the 2020’s and 2030’s?
