Antarctica's Ice Flow Fully Mapped For the First Time

tvlinux writes "Antarctica is a big continent, so mapping all of its ice flow isn't exactly a piece of cake. But for the first time scientists have been able to get the complete picture of the southernmost continent's ice flow, from the South Pole to the shoreline. From the article: '"This is like seeing a map of all the oceans' currents for the first time. It's a game changer for glaciology," said Eric Rignot of NASA's Jet Propulsion Laboratory in Pasadena, Calif., and the University of California (UC), Irvine. Rignot is lead author of a paper about the ice flow published online Thursday in Science Express. "We are seeing amazing flows from the heart of the continent that had never been described before."'"

Useless...

[Anonymous Coward]

What's the point of doing this since it's all going to melt in the summer anyway?

Re:Useless...

[riverat1]

Oh, there's enough ice there it will take several thousand years for all of it to melt. But the West Antarctic Ice Sheet could slide into the ocean pretty fast which would be a problem. A collapse if the WAIS would amount to over 15 feet of sea level rise.

Re:Useless...

[mapkinase]

I wonder if any of the models include a following factor: rising water level leads to increased surface of the water which leads to increased evaporation, which leads to higher rate of ice formation in both Arcticas.

Re:Useless...

[jo_ham]

Yes, I would imagine so, since surface area is an important part of the model.

Re:Useless...

[riverat1]

Rising water levels won't change the area of the oceans all that much. The oceans already cover about 71% of the surface of the Earth. Maybe that goes up to 71.5%. Rising temperature does increase the evaporation rate though. There is around 4% more water vapor in the atmosphere now because of rising temperatures. What rising water levels do to the ice on Antarctica and Greenland is raise the grounding line where the ice sheets/glaciers meet the sea which destabilizes that interface and probably increases the melt rate. Increased temperatures and water vapor in the atmosphere will increase snowfall on the ice sheets somewhat but that's balanced more or less by an increase in the flow rate of the ice sheets. I doubt there is a higher rate of ice formation in the long run.

Re:We need to send all the politicians there.

Don't you think all of the hot air from the politicians would cause a massive melt of the ice? Better to send them to Death Valley.

"The map points out something fundamentally new: that ice moves by slipping along the ground it rests on," said Thomas Wagner.

The story seems to suggest this is new information. Yet this is standard knowledge anywhere there aer icefields and the glaciers that flow from them.

Re:New discovery???

No, prior to this breakthrough, it was believed the ice just grew legs and walked off.

What happened to geology for its own sake?

There was a time, way back, when geologists would have presented this kind of finding and said:

"We finally have a map of how the ice in Antarctica moves. We don't quite know exactly why it moves the way it does, but at least now we know some of the questions we should ask ourselves."

Instead we get scaremongering drivel along the lines of: "That's critical knowledge for predicting future sea level rise. It means that if we lose ice at the coasts from the warming ocean, we open the tap to massive amounts of ice in the interior."

This would only be scaremongering if it weren't true.

1. Have you evidence that it is not?
2. Surmising (on presently available evidence) that sea rises due to melting ice is likely, how can talking about it be bad? Surely more knowledge is a good thing?

No. If you keep repeating "truths" out of all proportion, it is still scaremongering. That's why there are so many more people who feel perfectly fine driving a car to the airport and getting scared as soon as they board the plane - than there are people who are a paranoid, nervous wreak behind the driving wheel and relax upon boarding the much safer airplane (as it is indeed the case).

All that because news about airplane crashes are presented way out of proportion. If any passenger airplane crashes down anywhere on this globe - be it in Washington State, Siberia or Lagos, Nigeria - you'll know it. And they are all real. Not one is counterfeit or a fabrication. It just so happens, that 100% are being reported.

If there were as many dead people in airplane crashes as in car accidents, you'd need to have one major plane crash each day with over 100 dead people on average in the USA alone! Yet, much less than 1% of the car accidents with dead people are reported.

That's not to say anybody would be lying about the number of car accidents - but the biased reporting is very obviously having the effect of making airplanes appear much more dangerous than they actually are. The worst is, however, that it makes people talk and fight like idiots about airplane safety whenever there is a crash - but they all forget about the dreadful danger that car traffic is. There are far over a million dead people in car accidents each year worldwide. But nobody cares.

"What happened to geology for its own sake?"

People insisted that scientists show how their work is relevant to things of concern to taxpayers, because taxpayers are often funding part of the research. That pretty much sums up the reasons why the broader implications of a study get mentioned in journalistic reports no matter how interesting the regular scientific aspects are on their own. Science is the accumulation of a lot of smaller studies that incrementally add up. Individually they usually aren't some great revolution in understanding. But journalists love to increase the drama.

And it's not scaremongering. It's kind of like the grounded coastal ice is acting as a dam for ice moving from the interior. Remove it (by melting and/or breakup), and the ice streams will move much further inland and tap into the main parts of the cap, meaning you haven't just removed the coastal ice and added it to sea level, you've accelerated the movement of the entire land-based icecap into the sea. This is not scaremongering, it's the natural result of a better understanding the dynamics of ice motion in Antarctica. Having a map of the current ice motion over the entire continent is a big advance, and it also means the whole thing can be monitored for longer-term changes.

Re:What happened to geology for its own sake?

The real threat from sea level rise is zero. It would take a long, long time for all of that ice to melt; generations most likely. People will just naturally move inland as the water level rises.

The sea only rises if land ice melts (like on Iceland and the artic mountains). Ice that is already floating in water does not cause any rise in sea level when it melt (Archimedes worked this out a while ago)

Learn the difference between assertion and an evidence backed conclusion. It is not necessary to counter assertion with scientific analysis.

It's not like you're going to wake up in your seventh floor apartment one morning and find out that your balcony would now make a good dock.

There's a lot wrong with this. It doesn't require a full melt for the sea level to rise a few feet. Even a two or three foot rise could have devastating consequences. My parents have a small house in a small town in New England. There house is on a hill and so is pretty safe. But many of the other houses in the area are only a few feet above the high-tide line. If the sea level went up 2 or 3 feet, then when the sea gets really high during storms there would be real damage. Furthermore, some buildings have foundations that go down far which would then lead to problems with the foundations. It doesn't take water up to your balcony window to make the building have problems, that will happen well before that. What do you think will happen to a building with a basement that is partially below the water table? And relocating people takes a massive amount of economic resources and destroys national heritage ("Yes, children, much of where Paul Revere road through you've never heard of. It has been uninhabitable for 30 years." Do you want to have to tell kids that?) And New England isn't the only area that will have problems. New York City right now to keep the subways functioning on dry days pumps out around 13 million gallons of water. http://www.nysun.com/new-york/inside-the-mtas-fight-against-subway-flooding/35672/ And that's just the subways, that's not counting all the other pumps in NYC. Do you realize how much worse that will be from just a 1 or 2 foot increase in water level? Then add to this list a lot of cities in Florida. And that's just the more obviously impacted areas of the US.

And even this ignores the problem in less well-off countries. For example, many people live on small islands in the South Pacific. Consider Tuvalu http://en.wikipedia.org/wiki/Tuvalu which is not at all well off, and is so small that there's no part of it higher than about 15 feet above sea level. If sea level increases by 2 feet, then most of the island will become inhabitable. That's it. An entire country gone. They lack the money and area to relocate if the worst happens. And not surprisingly, they are a bit pissed off that our failure means that they might have to move. And they aren't the only example. There are literally hundreds of small islands in the Pacific which will suffer from sea level rise. And this isn't the only part of the world that will have trouble. Many South American countries have a lot of people on the coasts.

Then there's also all the secondary environmental problems. Many areas which are now fresh water will become much more saline. Fresh water fish will have problems. Water supplies currently used for drinking water will need to add all sorts of expensive desalinization equipment. Environmentally stressed areas like the Florida Everglades will run into even more problems.

So yeah, there's a serious threat here. And it doesn't require water going that high up. Only a few feet can have devastating economic, environmental and social consequences.

There's still a sizable amount of fear every single time I'm on that ride up on the airplane, and a huge amount of adrenaline every time I get to the door, even though I can handle my body in free-fall, and I'm in complete control of the canopy when I'm landing it.

Two feet per a century is one of the more conservative estimates http://epa.gov/climatechange/effects/coastal/slrmaps_probability.html.

It's highly unlikely the person being quoted meant the second "we" to actually mean that some human or humans were the sole actors responsible for the loss of glacial endcaps. Be mindful of the edge when borrowing Occam's razor, especially when using it to parse English.

Re:What happened to geology for its own sake?

[HiThere]

Warning: I'm talking off the top of my head, and I'm no expert, but:

Which current projections? I would have put the range at 1-30 feet, though I guess I consider 3 feet more reasonable. Of course, It's hard to be specific since a lot of what the result is depends on what we do. (I think the 30 foot range was predicting massive use of shale-oil, and poor conservation/pollution controls. Which, unfortunately, isn't at all an unreasonable projection.)

N.B.: It's quite unlikely that China/India/etc. aren't going to use the same energy sources that we use. And will probably be aiming for the same per capita usage. So perhaps that 30 foot projection isn't all THAT unreasonable.

FWIW, these are projections presuming only nominal antarctic melting. If Antarctica starts seriously melting we can expect much worse. I've been told that this probably won't happen. OTOH, there are presuming substantial Greenland melting...but then that's already underway.

Re:What happened to geology for its own sake?

[riverat1]

Here (PDF) is a 2009 paper on the subject. Check out Fig. 6 on page 5. The estimates for 2100 range from around 80 to 180 cm depending on the scenario. Of course there could be events that we can't foresee that would change that but more than 8-10 feet by 2100 seems to be beyond reasonable given what we currently know. If we keep on with business as usual though 30 feet might be possible by 2200.

Re:What happened to geology for its own sake?

[riverat1]

I should have included 80-1180 cm is 2.6-5.9 feet.

Re:What happened to geology for its own sake?

[HiThere]

If that "Intergovernmental Panel on Climate Change’s Fourth Assessment
Report" is the one I heard of, many professionals were complaining because the predictions had been toned down to be more politically acceptable. OTOH that 30 foot projection was a wild outlier. Just about as much as the 1 foot projection. (I think that thermal expansion of the oceans accounted for that, and perhaps a bit more, without any ice melting needed.)

Re:What happened to geology for its own sake?

[Anonymous Coward]

You're being facetious and trying to provide an absurd example to act as a straw man for climate change arguments. I get that, but I don't think you've chosen a very good counter-argument. The reality, however, is that a large asteroid or comet impact at some point in the future is a statistical certainty. It may or may not be in our lifetimes, but it will certainly happen. A Tunguska level event is estimated to occur every 100 years or so. Bigger events will happen less frequently. Chances are probably somewhere in some sort of appreciable range, say 5% or more that an asteroid or comet impact will occur in a populated area within the next 100 years and kill millions of people. The level of certainty that will happen, not to mention the long odds of a civilization destroying, or possibly human species destroying event occurring, probably justifies a few billion dollars thrown at the problem here and there.

Re:What happened to geology for its own sake?

[Anonymous Coward]

There are thousands of years of examples of human nature that entirely disagree with the notion that "people will just naturally move inland as the water level rises". That's not the way people behave en masse. It's naive to think that they will. What happens is that a disaster occurs and, if it's not so bad that it kills everyone, people evacuate, then most of them move back until the next disaster, rinse and repeat until either there's nowhere to move back to, or there aren't enough survivors left. People don't reach some threshold where they say "we're right on the edge of a disaster, let's move", most of them wait for the disaster and that's how they see that they've reached the threshold. Looked at from a distance, it looks like people are simply gradually peacefully moving away. Up close, there's quite a lot of terror and death.

Consider Pompeii and Herculaneum. Mt Vesuvius was erupting for a day without really harming anyone before it finally spewed up a huge eruption that killed absolutely everyone there within a few minutes. People were walking around while the ground shook and the mountain belched fire and ash and small rocks fell out of the sky like rain, going about their daily business as if it were just an annoyance. Very, very few people evacuated during that time, even though there was plenty of time for everyone to evacuate. They didn't because Vesuvius had been safe for their entire lives. That's how human nature works.

I'm not sure what the above paragraph should be implying... Probably that there's a discrepancy between the meaning and implementation of "rule of the people" and (perhaps depending on your worldview) there's no place with much more democracy to migrate to either.

As to taxes in particular, I think everything should belong to everyone by default. Taxes should be raised everywhere to give everyone food, water, shelter, medical care, education, roads, public transport and internet ("Apart from that, what have the Romans ever done for us?").

The capitalists can still have their playground within the rest of the economy. They should just not be allowed to run amok poisoning the planet and exploiting people who need to work their asses off for the basic "necessities" of today, as listed above (perhaps forgetting some).

While you are right that taxes aren't voluntary, they could buy you a better world. Larger socio-economic gaps create more tensions in a society. More crime and misery. Even the rich(er) are more uneasy in societies with greater economic inequality.

Mining competition for Antarctica

[Anonymous Coward]

Is this the start of the contest to Australia's claim of half of Antarctica in 2041?

What a wasted effort...

[Anonymous Coward]

According to climate change experts all of that ice will be melted by next year...

For those of you without a sense of humor... This is a joke... Please don't ask for a reference!

When did /. get to be so far behind the curve?

Fark had this on 20 Aug 2011 at 1:16 PM.

Yes, I've been here since it was Chips and Dips, I survived the Hot Grits, but I missed when /. became the place where articles were posted days later.

Yes they do. You choose to live in a country where the laws say you should pay taxes to finance civilization.

I mean, you need food to live. Does that mean paying the grocer is involuntary?

Re:"...isn't exactly a piece of cake."

[Anonymous Coward]

I can choose which grocer to go to. You might look up how difficult it is to get the IRS off one's back should you decide to expatriate yourself. The government is supposed to follow the Constitution, but it does not. What is my recourse? They violate the contract, yet I am chained to it.

"By being born to wherever you were born you accepted the eula."

Could be sarcasm, but it sounds like you mean it, in which case, you are clearly mistaken.

Being forcefully ejected out a birth canal is not considered an "agreement" North of the Bible Belt.

South of the Bible Belt there remain few "built-in democratic channels," since southerners have largely gone republican following the political pole shift of the late 20th century.

Also, freedom to migrate has been severely restricted ever since driver's license age requirements were raised to exclude newborn infants.

I hear there is a teapot between Mars and Saturn
