Large Ice Shelf Expected To Break From Antarctica
MollyB sends this excerpt from CNN:
"A large ice shelf is 'imminently' close to breaking away from part of the Antarctic Peninsula, scientists said Friday. Satellite images released by the European Space Agency on Friday show new cracks in the Wilkins Ice Shelf where it connects to Charcot Island, a piece of land considered part of the peninsula. The cracks are quickly expanding, the ESA said. ... The Wilkins Ice Shelf — a large mass of floating ice — would still be connected to Latady Island, which is also part of the peninsula, and Alexander Island, which is not, said professor David Vaughan, a glaciologist at the British Antarctic Survey. ... If the ice shelf breaks away from the peninsula, it will not cause a rise in sea level because it is already floating, scientists say. Some plants and animals may have to adapt to the collapse."
Will the ocean level rise, fall, or remain the same?
I'm betting it will rise a little bit because the salt concentration is different in the ice than in the ocean.
If tt's expected to, how is that news?
Ice shelves that don't calve would worry me more. But due to current media-promoted hysteria about "the environment", I think we should spend 100 trillion dollars to fix our planet. I mean, really, if we don't have a planet or environment, we're all dead. And think of the children!
"Some plants and animals may have to adapt"? Maybe we could collect them all and put them in an artificial environment so they can be safe from nature and man's evil nature. And then cuddle them - well, at least the ones that have comfy fur and cute eyes.
What happens when it melts? I think a chunk of ice the size of CT would cause a -bit- of a rise in sea level, wouldn't you?
The catch is that the ice shelves slow down the ice behind them which is pushing into the sea.
That ice is on land and WILL affect sea levels when it starts moving forward into the sea a LOT faster.
Even worse, glacier motion is lubricated by water - so if there's already a lot more meltwater under the glaciers --- whoooooshhhhh (in slow motion anyway)
How dare you question the word of the Gore-acle and Global Warming?
I mean "Climate Change", because it is awful tough to get people to buy off on warming when the planet is cooling. Yeah, our new "De-Politicized Science" is all about marketing.
Unlike the Arctic (which is just frozen water), Antarctica is actually a continent.
Now -- I know I could be wrong -- but I always thought in order to be a continent, a land mass has to be... land? Am I wrong?
Fact: Everything I say is fiction.
I have a burning question. Why is it now called "Climate Change" and no longer "(Man Made) Global Warming"?
There never was a good war or a bad peace.

Global Warming due to industry and emissions is a hoax...
The truth is the planet keeps getting warmer the closer we get to Hell.
Fortunately, Antarctica is too big to fail - rest assured our representatives are hard at work on crafting a bailout.

>>Fortunately, Antarctica is too big to fail - rest assured our representatives are hard at work on crafting a bailout.
I'll just return my Margaritaville.
That'll give us the trillions of dollars we need to bail out the oceans.
And what is the volume of ice that is resting on land? None of the surface area figures I've seen for the Antarctic specify how much of the area is actual land and how much is ice over water.
The tyrant will always find a pretext for his tyranny - Aesop
So you mean like: wwwwwwwwwwwwwwwwwwwwww hhhhhhhhhhhhhhhhhhhh ooooooooooooooooooooooo ooooooooooooooooooooooooo OOOOOOOOOOOOOOOOOOOOOOO ooooooooooooooooooooo ssssssssssssssssssssssss hhhhhhhhhhhhhhhhhhhhhhhh
I have 2 questions.
According to TFA, the Wilkins Ice Shelf has lost 1,800 km^2 of ice in the past year. This article states that the ice shelf is 200-250m thick. This gives volume lost of 360,000 km^3 to 450,000 km^3; 2000m*900m*200m, 2000m*900m*250m (easy numbers). Remaining area = (1800/.14)-1800 = 11057 km^2.
First question. Is it possible that over time (think glacial timeframe, not human timeframe) that the remaining 11,057 km^2 will rebuild the lost volume? How long is this process? If I remember correctly, Antarctica is a rather dry place regardless of the amount of ice and snow seen in pictures. This would require 32.5m to 40.6m of new packed snowfall/ice to replace what broken off in the past year; 360,000/11,057 = 32.5m, 450,000/11,057 = 40.6m.
Second question. What is the air and surface temperature impact of the hole in the ozone layer? link. Would the increased UV and microwave radiation exposure, especially in the Antarctic summer months, more directly impact surface temperature than global warming?
"The quality of life is determined by its activites."--Aristotle
It is hard to get a sense for the scale and the magnitude from the article's pictures. So, I looked it up on Google Earth.
That "ice bridge" protecting the Wilkins Ice shelf is narrow, only about 2 km wide, or slightly more than mile. And it is that which is breaking up. The floating ice area behind it (i.e. to the east) is huge, about 100x100 km!
Once that bridge is broken, sea currents may more easily flush that ice into the high seas. And, what the effects will be then, we don't know I guess.
.
Let us hope that this Vaughan will not be allowed to read poetry to us. Who knows, maybe we'll die from internal haemorrhaging or the Earth will get destroyed..
Here's a chart of the global hurricane index. It's the lowest it has been in the last 30 years!.
That is probably because the globe's ocean heatcontent is dropping
I remeasured it, the ice bridge is about 60 km long and 3 km wide at its waist.
Never mind the article, it's right there in the summary: "it will not cause a rise in sea level because it is already floating, scientists say"
Imagine if Florida is flooded by rising sea water? All the false teeth and hair pieces would devastate the Atlantic Ocean. I mean Polygrip and Vicks Vapor Rub can't be good for fish. Polyester suits and Golf Balls have to have a bad effect as well. Add in all the Cocaine and pot and you wind up with a lot of stoned fish choking to death on bad hair pieces. Think of the children hell, think of the fish. The picture of a fish coughing up bingo chips is enough to bring tears to my eyes.
Slightly OT: an interesting doomsday scenario was predicted in the sci-fi thriller novel Icefire, by Reeves-Stevens, where a rogue faction in the government of a large country detonates a bunch of bombs around the edge of the Wilkins ice shelf to detach it from land, and then detonate a big blast above it, in effect slapping the ice shelf into the Antarctic Ocean and creating a tsunami that threatens to wipe out the Pacific Rim --Hawaii, California, Japan, etc. It's a fast-paced novel about how the protagonists try to outrace the tsunami wave, which will take most of a day to get to the Pacific Rim, and how they try to warn various incredulous government organizations about how big the danger is, etc.
Oops, waitaminnit, that's the Ross Ice Shelf, not the Wilkins Ice Shelf. Sorry, wrong shelf.
Anyway, worth a read on your next flight that doesn't have WiFi to keep you occupied.

Interestingly, the land ice exerts a gravitational force on the surrounding water. This causes the sea level to rise in the vicinity of the ice. If the land ice melts than the sea level will drop (locally at least).

Because they original "AGW" scientists saw the writing on the wall. There is no human-caused warming, only natural variation. So how can they preserve credibility? Why, change the name. Now, no matter what kind of natural, cyclical change happens, they are bound to be right: "we said 'climate change' and the climate changed".
I'm old enough to remember the last global-cooling scare. In 10 to 20 years, we'll all see the next one, as a new generation of lousy researchers confuses anecdotal evidence with science.

Or, if it is warming, we should adapt to the changes instead of addressing economic activity. That's when they show their true colours.

The ice shelf is imminently expected to break away from ONE island which is considered part of the Antarctic Peninsula. It will still be connected to another island which is considered part of the Antarctic Peninsula.

Seriously, the only reason we hear about these icebergs is due to people using fear to scare mankind into making costly measures to prevent some mythical disaster. Mankind has a remarkable ability to adapt to change. The creatures of this earth also adapt to change. If the conditions are not favorable, they die. Why after all these years of living on this planet do we think we have the ability to stop it? I have seen figures saying more will be spent to ATTEMPT to stop warming than will be spent adapting to the change. It is a SHAM we are trying to stop natural change and are AFRAID to adapt.

Even worse, glacier motion is lubricated by water - so if there's already a lot more meltwater under the glaciers --- whoooooshhhhh (in slow motion anyway)
Highly compressed landmass under glacier could expand rapidly when glacier slides and weight distribution changes. Resulting earthquake would destabilize surrounding glaciers even more and even worse, could cause a tsunami. Talk about self-reinforcing loop.

Maybe that's why that inconvenient truth isn't out there, because it perhaps ISN'T TRUE.
And china already have a declining population (child control: when are YOU going to get limited to one child per family???) and the also took up all the outsourced manufacturing jobs and all the emissions needed to support that. Inconveniently enough, despite having removed heavy industry to China, your country didn't drop its pollution rate.
You can't do justice to the slowness of this whoosh. It reminds me of the Austin Powers scene where a Austing commandeers a very-slow-moving steamroller and steers it toward a security guard who, standing in its path, screams and cowers interminably but fails to simply and slowly step out of the way.
If you're rich enough to have a house so large as to be unrelocatable in the time frame we're talking about, then I am not concerned about your ability to survive. And if you're impoverished and living in a sea-side hut, then I have great confidence in your ability to adapt to the change.
And what of the costs of relocation? That's an unfortunate inefficiency to me. But for the people who are able to rationalize jobs created through "green" regulations, it *should* be as easy to rationalize the relocation requirements as "creating jobs".
Sheesh.
From the fine article: "It is the largest ice shelf on the Antarctic Peninsula yet to be threatened." So, thinking about the US response to "threatened" spiders, frogs, and other critters...that language prepares us all to have our own rights restricted in deference to ice chunks. Sheesh.
the problem of expecting a CO2 market to emerge is that its basically worthless. Everybody can make CO2, its the getting rid of it is that tricky part. If you really wanted to make money, then take a CO2 tax, and then use the money to construct giant atmospheric scrubbers.

The name Climate Change is a lie. If its global warming that you are hawking, you don't change what you are selling because the guy in minnesota is having the worst winter ever. This kind of constant rebranding just infuriates me because it makes me think that the people doing it are a mess of liars. If you think the planet is warming up, call it global warming, because that's what it is.

Heh broken ice ... so mebby a few penguins get smotched. But hellsbelles we shoulda imported a few polar-bears decades ago. Keeps the lil' tux-b*stards frisky. Oh yeah... ice. Drop a cube-or-two into my martini ... please.
Climate Change more accurately reflects that it's going out of whack in both directions.
I seem to remember Al Gore stating that when CO2 levels increase, so does the temperature. So are CO2 levels increasing or not? If they are, then call it "Global Warming". Changing the term to "Climate Change" sounds, to me, like a child who keeps adding on to his "story" every time he's caught in a lie.
Interestingly, the land ice exerts a gravitational force on the surrounding water. This causes the sea level to rise in the vicinity of the ice. If the land ice melts than the sea level will drop (locally at least).
Uh... If the sea level drops locally, then it means that the water goes elsewhere, ie. the sea level rises globally.
if we replant the forests, what are the terrible, terrible consequences?
While I support stopping deforestation and support planting more trees, science is all over the park as to whether planting trees will actually absorb more CO2 than what is emitted do to their planting. Some research shows more CO2 is emitted from planting trees than the trees will absorb. I think more research should be done.

Shelf ice is like an ice cube in your coke. If the ice melts the coke level will neither rise nor fall. And the same thing happens when you are playing with large ice cubes in an ocean.
True, melting ice doesn't raise sea level however thermal expansion does. There's also the ice on land, when it melts it runs to the sea which does raise sea level.

conditions. Shifting away from our current very complicated tax system toward one that both functions to discourage wasteful consumption and simplifies the tax code [eliminating many tax loopoles in the process] may actually offer an overall economic benefit outside of the environment its self.
I and others have proposed as much. I'd like to abolish individual income taxes and replace it with consumption (sales) and pollution taxes and usage fees. That is at the federal level. At the state and local levels property taxes can also be used.

The actual problem with the CO2-certificates is that they are not reduced every year and they get it for free.
Cap and trade can do this. Cap how much can be emitted then auction off permits to emit. If an entity emits more than they have permits for they either have to buy more from those willing to sale or they pay a fine. Then each year the cap is lowered. Of course the devil is in the details, Europe was gung ho with cap and trade but they haven't been able to get it to work right. Also there's a problem with deforestation, deforestation in the Amazon and in Indonesia are big contributors to emissions. Perhaps those who want more permits can pay to preserve forests and or reforest areas. Another problem, Bush came out against Kyoto because it didn't limit every nation, is that some nations will not accept emission limits. China has now surpassed the US as the largest emitter of greenhouse gases.

*remove regulatory barriers to the development of nuclear power, 3rd generation designs are of sufficient safety and can serve to take the burden off of fossil fuels in regard to energy.
You say destroy subsidies to industry then you say the above. If not for subsidies nuclear power would not exist. The freemarket CATO institute published an article originally from Forbes entitled "Hooked on Subsidies" that goes over the cost of energy and shows nuclear power is too costly and would not be profitable without subsidies. If left strictly to the market nuclear power plants would not be built, not even in China, France, India, or Russia.

Yes and that stuff about drinking 8 glasses of water a day is garbage(though it might actually be good for you if the water was oxygenated). Btw, from my understanding fluoride actually acts to reduce IQ among other things (such as brittle bones) and was used in water by Nazi Germany to keep prisoners from wanting to escape concentration camps. Just a little tidbit. Take the Red Pill and wake the fuck up.

I don't know about fluorine reducing IQ but it can cause fluorosis, which as one of the photos shows can cause the mouth and teeth to be stained, and cause brittle bones. What happens is that fluorine replaces calcium in the bones which weakens them. I don't know the validity of it but it's been suggested that that's why the elderly break their hips and other bones easily.

It's called climate change and not global warming because while the earth as a whole is supposed to be warming in specific areas it can actually cool. It makes no sense to say warming when some places will have lower temperatures.

I have concluded that observing that even the possibility of global warming should be a matter of great concern is pointless when you are dealing with people who believe that all problems relating to the melting of ice can be corrected by adjusting your gin to vermouth ratio.

This is news because???
a) We need more grant money.
b) Must raise taxes on 'carbon'.
c) Ice shelves do that.
d) All of the above.
The two aspects of global warming that no one can answer with any certainty are: 1) How much climate change is natural vs man made; 2) What are the repercussions. The world has spent a lot of time and money trying to answer both of those questions and still cannot.
If we had applied those resources to solving world hunger instead of climate change, I'm guessing we could have saved millions of lives.
Is it just me or does it seem idiotic to assume that a map made in the 1930s is accurate enough to make predictions about loosing ice.
How much more? I doubt there is a major difference even in the worst case (compared to other major sources of CO2 emission), and there are many other good reasons why replanting trees is a good idea in general.
First, notice I said "I support stopping deforestation and support planting more trees" so I obviously believe it's a good idea to plant trees. So on to "how much more?" Do more research until science figures out what trees to place where, how to plant them, and what the effects will be.

The perverse incentives in the Kyoto Protocol were especially concerning.
What's even more perverting is that countries in Europe and elsewhere use biofuel to reduce their emmissions. A lot of that biofuel is made from palm oil which is imported from Indonesia. And how does Indonesia get it? The Bog Barons raze rainforest and drain the bogs to grow palm. This causes more CO2 to be released than if petroleum was used for fuel. That "New Scientist" article explains it pretty good.

Thank you for that interesting link!
One of the things that really worries me about this whole 'climate science' thing is the incredible amount of ego, posturing and politics involved. I started years ago with just assuming that the climate scientist were knowing what they're talking about. I'm a physicist, and know how science in physics works, and I pressumed that it would be the same in climate science. But then these creeps like Al Gore started adding their (considerable) weight to the debate with the science is settled.
Ofcourse the science can't be settled. Hardly any science is settled, let alone one as young as complex and as unexperimentable as climate science.
Then I went to a lecture by Amsterdam Paleo-Ecology professor Dr. Bas van Geel, who clearly showed that there are definitely many open ends and that it's unsure what proportion of the warm late 20th century is due to manmade CO2.
It bothers the hell out of me that something that has such large consequences already (extra taxes and such), and maybe large consequences in the future (real climate change, caused by us) is being run like a bloody kindergarten. I'm pretty sure that the late Richard Feynman would have called climate science an example of his Cargo Cult Sciences, that uses the tools of physics without its way of thinking.
All in all it bothers me that both sides (Mann, Watts, Hansen) have political agendas and use their positions (important blog, head of GISS) to pervert this whole process of collecting knowledge.
I'm fairly sure we'll know quite a bit more in the coming decades, and for know it pleases me that the majority of the population is becoming as sceptical as I am.
