Larson B Ice Shelf In Antarctica To Disintegrate Within 5 Years
BarbaraHudson writes: A new study (abstract) from NASA scientists predicts an Antarctic ice shelf half the size of Rhode Island will disintegrate around 2020. The shelf has existed for roughly 10,000 years. "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." At its thickest point, the ice shelf remnant is a half kilometer tall, and spans approximately 1,600 square kilometers. "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."
Quick, we need everyone to pile on for why this proves catastrophe is imminent and favored policy changes must be passed. Then the other half can pile in and explain why this means nothing and the next ice age is still coming...
Ironically, Rhode Island will need this mass, because half the state will be under water.
The last 12,000 years has been an interglacial period. Melting is normal. It is better than freezing.

Fun fact: Alarm is a completely rational response to alarming events, regardless of frequency.
Burn the hairitic! Unbelievers are not welcome here!
thanks... quite disheartening to see /. devolve over the years... what a waste of bandwidth
Contradict ? Reading comprehension not so much ?
One talk about land ice and the link talk about (the same) OCEAN ice study
from YOUR link "...and the continent's sea ice has set new records for the past three winters. At the same time, Antarctica's ice sheet (the glacial ice on land) is melting and retreating"
Gee, it's a good thing Anthropogenic Global Warming is just a Big Leftist Conspiracy, or imagine how bad things would be!
How much evidence is required before denialist clowns will be convinced that Global Warming is a thing, and it is almost certainly Our Fault? It's kind of amusing that the same people that will shovel 100's of $B and sacrifice thousands of lives to counter theoretical threats posed by countries all over the world somehow require absolute irrefutable "I must personally get burnt before I'll ever admit fire exists" proof when it comes to climate change?
One must note that the ice sheet has **ONLY** existed for 10,000 years.
It's very important to stress this point, as those who do not understand geologic time are at risk of thinking that 10,000 years is a long time.
It's a nanosecond on the geologic clock.
This is a very young icesheet. It's loss is noteworthy, but does not have significance when viewed on macro timeframes.

Do not confuse climate change from the weekly Alarmist news release. The right wing disputers have muddied the water and polarized the public. (OK, too many metaphors) . What's with the media, including our esteemed slashdot, automatically posting any alarmist report each week. Indeed, many of them contradict each other, and sometimes a theory from one week appears in a press release a few months later as an established fact. This is not science! It clouds the study of the climate just as much as the right-wing nutcases. Stop appeasing the alarmists just to contest the nothing-is-happening group.
Earth is not a stable static thing. It changes. All the time.
Fun fact: Alarm is a completely rational response to alarming events, regardless of frequency.
Except that in this case the "Alarm" being raised is due to the output of some computer simulations that are trying to predict the future.... Simulations I might add which have been wildly wrong in the past, but they claim to have fixed now. Of course none of this "alarm" has anything to do with political and financial power either....
Riiight...
So in this case, the RATIONAL thing to do is to be a bit skeptical of all the alarmist rhetoric about things where there obviously is a potential for political and financial gains by the people making the claims.

How religious of you... Nice to see that somebody has correctly identified the source of the alarm... Looks like worship of the earth to me!
I'm of the third position, that we could have fixed this 50 years ago. But now it's too late and we're all screwed. Time to stock up on supplied for the apocalypse and ride this thing out.

No, the alarm is triggered by events on the ground. The models are just responding to those.

Isn't there anywhere that's half the size of Rhode Island that this ice shelf could be compared to?
systemd is Roko's Basilisk.
Except you're wrong: On the timescales of human civilization, climate is virtually static. Civilization is pretty solidly predicated on world temperature and climatic patterns being what they are, and the oceans being the height they are (ports and coastal cities having been a Thing since the beginning of civilization). The collapse of more than one civilization can be attributed to shifts in climatic patterns over centuries, and we are now driving measurable, substantial changes on scales not comparable to the age of civilizations, but a single human lifetime and soon even mere decades.
Knowing this fact, perhaps we shouldn't knowingly and deliberately be doing a frantic tango on some of Earth's primary climate control levers. And even if we *have been*, now that we realize it's a really bad thing we should *stop doing it*.
I for one can't wait for boating season on Lake Vostok.
Please forgive me for hijacking this thread with a question related to the Larson B Ice Shelf rather than global warming, but I was hoping someone could shed some light on how this ice shelf formed during the current interglacial. I would've thought more or less all of the major ice shelves and glaciers around the world were relics of the Pleistocene, but it sounds like this formed during the hottest part of the Holocene (with the possible exception of today).
Stop learning! Only you can prevent esoterrorism.
so, like, an ice cube.
The only thing certain about climate science is that it isn't actually a predictive science as the long list of their failed, and thus falsified, hypotheses demonstrate. They have yet to make any actual predictions with dire consequences that have actually come true. Meanwhile the global sea ice is at record levels, Antarctic sea ice is at near record levels, even the Arctic is the same as it was ten years ago and as it was back in the 1970's (per Nimbus 5 satellite data).
When climate scientists predictions start to actually be validated then maybe they can be taken seriously. Till then they are not much better than doomsday rapture prognosticators like Harold Camping.
Don't worry, eventually the simulations will cause enough CO2 to melt the ice sheets by itself.
Then all the predictions will be true.

You will notice, I hope, that of this list, only the dailycaller has even a slight tendency to not parrot liberal talking points, I hope?
...maybe we'll see more of that petrified wood from Antarctica.
You know, from when it wasn't snow and ice? (Yet somehow the world didn't end?)

From all the previous ones? To date, a coin flip is still far more accurate than long-term climate predictions based on mathematical models.

I'm denying the existence of deniers - there are only pro or anti geo-engineering advocates.
Wow. You just caused a major deja vu for me. I'm recalling the baffling moment when I was trying to talk about dinosaurs to another child at school and he authoritatively explained to me that his father had told him that dinosaurs were just made up by scientists who had dug up some old bones and put them together wrong. I mean seriously. At the time, I was pretty much an expert on dinosaurs and I was, in fact, well aware that Iguanodon, for example, had been put together wrong at first. But no, that wasn't what he was talking about. It was one of my earlier experiences with that form of prideful, willful ignorance and I just had no idea what to say.

I'd be interested in a small wager on the outcome of this prediction. Without knowing much about it, I'll bet that it comes true in slightly more than five years, say seven years. Anyone want to bet a small sum that it doesn't come true? A small sum to me is, oh, between five and two hundred dollars.
How many should we kill off with smog? Starvation? That's what we'd do if we don't change our energy production methods.
That's right, for 8000 years the interglacial WAS COOLING. Until, really, the last 100 years. Then it DRASTICALLY reversed.
Yes, theoretically, it could have warmed instead, but to do so it would have required to be different from every other interglacial, but there's nothing logically or mathematically stopping it from happening. For example, some fuckwittted species could release massive amounts of CO2 into the atmosphere and make it warm. That would do it.
Of course, the same fuckwits would blame it on nature, because they know they're blameless for everything. It's always nature's fault, god's fault, satan's fault, the fault of the liberals, the fault of goverment, the fault of the left, the fault of the hippies, the fault of the nimby's, the fault of ANYONE ELSE BUT THEM.
And if that doesn't seem to work, it's not happening at all.
I don't decide that the science must be wrong.
Gravity's pull on objects is settled science. Things really do fall down when you let them go. I do not therefore go and think that there's no such thing as gravity.
CO2 is a greenhouse gas. Settled science.
CO2 increases are from humans. Settled science.
Most or more than all (it would normally be continuing the cooling trend if not for us) of the recent warming is settled science.
How much, precisely? Not settled.
None or less than none? Settled. Both are bollocks.
Is it the Sun? Settled science. It's us. The sun is cooling
Is it cosmic rays? Not settled, 100%, but nearly so: every test so far shows no.
Gravity? Settled.
What causes gravity? Still debating, not settled.
Measure ice at the hottest time of the year take pictures and claim its decreasing every year. Send story to media to push Globalist agenda. Profit.

Subsurface volcanoes anyone?
A question for everyone who thinks that CO2 controls the climate. How long with rising CO2 and flat or falling temperatures before you admit your theory is wrong? 20 years? 30? Never?
All 5 of the major datasets (RSS, UAH, HadCRUT4, GISS, NCDC) show no warming for between 15 and 18+ years. In that time CO2 has risen 8-10%.
There is a simple and relatively cheap way to stop the ice from sliding off into the ocean. It's well understood and has been used in large numbers for 40 years.
I refer to the Trans-Alaska Pipeline supports. There is a picture here of one of the thermal diodes that keep the permafrost frozen under the line. They are dirt simple, a pipe with a few gallons of ammonia or propane.

Far as I know, nobody has yet studied what it would cost or how to pay for it, but enough of them would freeze the glaciers to bedrock.

Wow! It is a good thing global warming is a hoax. :):)
I have this snowball and it was cold this winter... You mean my senator's are actually uninformed/greedy bigots? @.o
I just don't get... eh, ugh... never mind. This post wasn't worth the research I put into it.
ZOMG all animals will be extinct in six months unless you give me lots of grants for "research" which supports my need for more grants. Then when it doesn't happen, I'll crow about what a great job I'm doing!
When did this site stop being a tech site and become the Climate Change (TM) newsletter?
According to past predictions, there was to be no Arctic ice by 2015 (also every other prediction has failed to happen). Global Warming is a Fraud. http://news.discovery.com/earth/global-warming/arctic-sea-ice-reaches-new-record-low-120920.htm
