Arctic Ice Cap Rebounds From 2012 — But Does That Matter? 400

Posted by timothy
from the ask-me-in-a-few-decades dept.
bricko writes "There has been a 60 per cent increase in the amount of ocean covered with ice compared to this time last year, the equivalent of almost a million square miles. In a rebound from 2012's record low an unbroken ice sheet more than half the size of Europe already stretches from the Canadian islands to Russia's northern shores, days before the annual re-freeze is even set to begin. The Northwest Passage from the Atlantic to the Pacific has remained blocked by pack-ice all year, forcing some ships to change their routes. A leaked report to the UN Intergovernmental Panel on Climate Change (IPCC) seen by the Mail on Sunday, has led some scientists to claim that the world is heading for a period of cooling that will not end until the middle of this century." "Some scientsts" in this case do not include Dana Nuccitelli, who blogs cogently in reaction at The Guardian that the 60 percent increase observed in Arctic ice is "technically true, [but] also largely irrelevant." He has no kind words for the analysis in the Daily Mail (and similar report in The Telegraph), and writes "In short, this year's higher sea ice extent is merely due to the fact that last year's minimum extent was record-shattering, and the weather was not as optimal for sea ice loss this summer. However, the long-term trend is one of rapid Arctic sea ice decline, and research has shown this is mostly due to human-caused global warming." If you want to keep track of the ice yourself, Arctic Sea Ice News & Analysis offers frequent updates.

      I expect their models to start matching reality at about the same time as global climate control becomes reality.

          Or it could be that the whole AGW platform has been hijacked by those pushing "cap and trade" [youtube.com] who will make a mint thanks to the scam being written by the ones who came up with credit default swaps [nakedcapitalism.com], you know, the ones that nearly wiped out the economy when their make believe numbers turned out to be bullshit?

          I'm sorry but I don't give a shit WHICH side you are on, if crap and trade didn't cause a giant bullshit sign to appear over your head you frankly haven't been paying attention. Crap and trade is a classic reverse Robin Hood where all the poor and middle class will pay more while those like the Rev Al Gore farts around in his private Lear jet, rides in a fleet of SUVs, goes to his McMansion with indoor ACed basketball court, yet has the brass balls to say he is "carbon neutral" because he pays himself credits from his own company which would be like me moving money from my right to left pocket, calling it "wealth redistribution" and demanding and GETTING a tax break for it!

          You wanna cut down on AGW? Fine by me, there are plenty of common sense ways to get started like putting out a "people's car/truck" that gets over 40MPG and is cheap enough the poor can afford to replace all those used gas guzzlers on the road, paint roofs and roads white to stop the heatsink effect, plenty of things we can start doing tomorrow to get the ball rolling...but you will never hear about any of those, why? Because it don't let a handful of rich douchebags like fatass Al Gore help themselves to your wallet and the government teat, THAT'S why.

          A gesture that would go a looong way to getting the skeptics onboard would be to tell that fat hypocrite Gore to jam his Lear Jet up his ass, if you want a spokesman? Got the perfect guy, Ed Begely Jr. That man actually walks the walk, lives in a modest 3 bedroom, drives a small electric with a bike rack so he can bike short errands, he does everything in his power to cut down on waste and pollution. You look at Al Gore and pals and what you see is the classic "do as I say not as i do" bullshit of the rich and spoiled, and until Gore and his ideas get pushed off an iceberg a lot of us will simply call it what it is, a scam, and vote against anybody who supports him and his bankster buddies.

              The ability to spot a scam is VERY easy, here is how: If a bunch of really REALLY rich people are banging the drum of support, ask yourself THIS question....what is in it for them? From Gates "donations" of software and support for USA style copyrights in the third world to Al Gore and his crap and trade bankster buddies you can be damned sure there IS something in it for them, the rich rarely do anything that doesn't give them at least some ROI, that is why they are obscenely rich after all.

              In the case of crap and trade what is in it for them is trivial to spot, the "rules" are being written by Goldman Sachs, right up there with Halliburton and Monsanto on the "rich evil muthafuckers" scale, so you KNOW its gonna have loopholes up the ass and wadda ya know? They ALSO own offshore crap and trade businesses to sell credits, isn't that amazing? Who would have thought? Oh and watch the video, you'll see that many corps will get grandfathered in, so your biggest donors...err...polluters? they'll get a pass, its YOU, the poor dumbass that can't buy a lobbyist, that will have his wallet raped.

              If I told you I could sell you a magic rock that for a billion dollars from every country on the planet would stop AGW, would you believe me? So why are you willing to believe Rev Al Gore when he has NOT ONCE, not a single fucking time, said a God damned thing about closing trade to countries that have already said they won't let Al and pals rape THEIR economies, like ohhh...China and India? Oh right, Al and pals make crazy money off the Chinese and Indians, how silly of me.

              DO NOT BE SCAMMED FOLKS the scammers are using a combination of appeals to emotion and "we have to DO something!" but their "something" merely empties YOUR wallets into THEIR pockets and does about as much as my magic rock, IE nothing. All crap and trade will do is kill any chance of businesses building shit here, since they can build in Asia crap and trade free with ZERO penalty, Al and pals will make money both on the cheap Indian and Chinese labor AND on taking what little is left in your wallet, and all you'll get is told "Oh well this isn't doing enough to "save the planet" so we need to raise prices by 30% for carbon indulgences....err credits, yeah that will save the Earth!". Bullshit, the only thing it will "save" is a seat for Al and pals in the billionaires club, you will get a magic rock and a big bill.

                It's kind of silly to lay cap and trade on Al Gore's doorstep. Cap and Trade is the 'business-friendly' version of carbon regulation - i.e. the only kind of regulation that stands a chance of passing in today's lobbyist-owned government. I'm sure Gore would tell you a carbon tax would be a more efficient way to reduce consumption - even a revenue neutral one (that distributes the proceeds back to the public). But try proposing a tax as a solution to anything (and calling it a tax). Recipe for gridlock. Anyway, we have gridlock regardless, and cap and trade isn't gonna happen - so why are you railing on about it?

            the laws of physics care not what Al Gore thinks or does.

            it does not matter if it is Al Gore, JP Morgan & Co., or Colonel Fucking Sanders who points it out: internalising the market externalities around the burning of fossil fuels is the single greatest tool we have to do something about this before it is too late.

            we know pretty much how many barrels oil, gas, and coal we sell (and so extract and burn) each year. We know quite well how many molecules of CO2 that will release. We know, pretty much, since the mid-1800s (starting with Fourier) what effect that CO2 will have on our atmosphere. We monitor it both in amount and radioisotope and it matches expectations pretty much spot on.

            arguing over the minute details or the character of the messenger is both totally irrelevant and short sighted, not to mention intellectually dishonest.

            A cap and trade marked based solution worked beautifully for SO2, there's absolutely no reason it wouldn't work for other pollutants as well, beyond intentional and sociopathic sabotage that is.

            As an environmentalist (she worked as an environmentalist involved in carbon trading) explained to me, it doesn't matter if CO2 doesn't turn out to be a problem, because by cutting CO2 you force a reduction in production, and a reduction in consumption. Then she added with emphasis, "it's about reducing greed."

            You just have to look at the "solutions" people are proposing to see their worldview and political outlook. If the science didn't support their worldview, they'd look for some other way to justify it. A worldview (and we all have one) is self-justifying, self-validating, it-looks-like-a-duck-because-i'm-obsessed-with-ducks.

            Note the environmentalists who hold up signs saying "we come armed only with peer reviewed science" (UK's anti-airport groups) but they don't hold up those signs when they protest against GM. Their worldview comes first. Gee there's no evidence that GM is bad? Well we'll protest against it anyway because we know better.

            Unfortunately they seem to have a worldview which operates at a lower level of complexity (huuumans baaaad) and so the money-wheelers-and-dealers and corporate types who actually have to work and excel and network and create results (even if only made up results) run rings around the environmentalists, not by defeating their aims, but by exploiting them. Oh carbon trading, what a great made-up-money paper thing, fantastic. Oh windfarms, great let's soak up all that subsidy for our big landowners, etc. "Every wind farm is a gas plant" they say at their corporate conferences. Many activist environmentalists are too stupid and lacking in skills to find good answers to environmental problems (and to be fair they are very hard problems), and instead have this "new-age" culture of oh how lovely if we all went back to pre-industrial levels where we can all live in a small village and sing songs around the fire. Which kinda ignores that in pre-industrial times, you needed many to be in slavery just to provide the "cheap energy" -- today, oil and gas is our "slave power", which is why we can live daily, as if with the energy of hundreds of slaves at our disposal.

            So excuse the wild rant, but that's just to illustrate (not prove) a point, that you can put the science aside and say, ok, what if we're facing AGW, what's the solution? And then the "solution" will be a function of people's worldview. Many answers are from pre-modern world views, maybe new-romantic, maybe Marxist, and especially from people who can't count. Oh if we all made a small change... yeah it would all add up to a SMALL change. Try living without electricity, see if you can handle that change.

            The rest are power and money drives. Real solutions are basically coming just from the gradual improvements in technology and systems, improvements which have been going on for hundreds of years anyway.

            I honestly think they should go live in Third World countries for at least 10 years, and see what the majority of the world is like, and what problems they are facing. Live like the locals do, not just drive around in your SUV lecturing people on how they should live. Heck even my grandmother never had a fridge. I mean the arrogance is astounding, if not, you know, also kinda cute for its naivety.

            Anyway this is just a rant, nothing real to see here, move on. Have a nice day.

              And they all failed to prove Einstein wrong, in the same way everyone who has tried to prove the climate models (fundamentally) wrong have failed. For anyone who isn't a physicist, don't you agree that it is relevant to note that the vast majority of physicists agree that Einstein's theories of relativity are correct?

              - Patrick Moore left greenpeace (which he helped create) because it bothered him that the entire movement was basically hijacked by socialists. [...]

              Then don't listen to Greenpeace! It doesn't matter what they say, listen to what climate scientists say. Forget about Greenpeace.

              [...] This means we could have periods just like the ones we are in now where there's a sudden heat spike, followed by cooling, and what we're seeing now may even be something that happens all the time. [...]

              For what reason would there be? If that were the case you suddenly have two new problems to find explanations for: 1) There would have to be a mechanism that can cause sudden spikes in the Earth's energy exchange at a planetary scale, other than greenhouse gases; and 2) You need to find a reason why the current increase in greenhouse gases, which should have exactly that (heating) effect based on pretty basic physics, for some reason doesn't.

              - Besides all of that, we already have well known periods where the earth was so much hotter than it is now and had a CO2 PPM ten times what we have now, and very large scale life thrived pretty damn well. In fact, quite possibly the "greenest" period in history:[...]

              Apart from the somewhat dubious claim that it was the "greenest" period in history, then yes, there has been periods with much higher CO2, and consequently a much warmer climate (despite a weaker solar radiation back then). Nobody, who knows what they are talking about, is claiming that a hotter climate precludes life -- that isn't the issue. The issues are that:
              1) Many current organisms will not be able to adapt that quickly to a climate change, meaning we will lose much biodiversity for some millions of years until new species have developed. This isn't a problem for "life" itself, but a loss for humanity.
              2) Human societies will take a pretty big hit in adapting to a hotter world. For one thing, during such warmer periods as you refer to, the sea level was 50 to 70 meters higher than it is today. We are of course not talking about any such increases in the near term, and we could probably adapt to even such extreme changes without going extinct if we had to, but the cost of for example moving portions of coastal cities (to name one of a long range of potential consequences) just so we can continue to use oil for a few decades longer than we otherwise would have (since it runs out anyway), is completely disproportionate. There are other energy sources.

              By the way, I find it somewhat interesting that you say we have "well known periods where the earth was so much hotter", talking about periods hundreds of millions of years ago, a few sentences after you declare your distrust for historical temperature records because "we weren't actually there to measure it proper thousands or millions of years ago". Which way do you want to have it?

        80% of climate scientists who were asked last year expected more ice this year than 2013. So this is hardly an unforseen event. The blog link mentioned in the summary [theguardian.com] explains why, but I'll repeat it since you didn't read it.

        Arctic ice volume has a falling long-term trends, but on top of that there are short-term year-by-year changes. You effectively have a long-term signal with short-term noise on it. As you can see from this figure [nsidc.org], the trend is about -0.065 million square kilometers per year, while the year-to-year variations are 0.5-1 million square kilometers. Hence, on a short timescale you can basically only see the yearly random variations. If you suddenly see a large jump, it is much more likely to be a short-term change than a long term one, and several years of observations are needed to see if the long-term behavior has changed or not.

        The point now is that if you happen to get a particularly low value of the random yearly variations one year, you are likely to get a larger value the next year. Much like if you roll a die and get a 1, you are likely to get a larger value the next time you roll, simply because there are more values (2,3,4,5,6) that are larger than 1 than those that aren't (1). In general, extreme values are unlikely, and the chance of getting several of them in a row is much lower than getting one of them followed by less extreme values. This is called regression toward the mean [wikipedia.org].

        So to summarize, this was expected, and predicted, and no models will have to be changed based on this observation.

            Yes we can.

            2007 was an exceptional year for ice melt, a 1 in 1000 event. In a stable climate we wouldn't expect to see that record beaten for ages.

            But just six years later we saw that record broken. That tells us that either there is a trend in ice extent (there is) or, alternatively, variability is increasing (also generally not a good thing as most living things need a fairly stable environment to survive) or both.

            Even after the exceptional rebound this year, we're still one SD below the long term trend line. Things are not looking good in the arctic at all.

      Perhaps sea ice extent oscillates between the North and South Poles

      • by riverat1 (1048260)

        Perhaps you could put some meat on your hypothesis that sea ice extent oscillates between the poles. But in reality there is little or no connection between the two. The situations are quite different, the Arctic being an ocean surrounded by land whereas the Antarctic is a continent surrounded by ocean.

        There are some explanations for the increase in Antarctic sea ice. One part of it is that the winds that circle Antarctica have strengthened, possibly related to the ozone hole over the continent. This t

        Perhaps sea ice extent oscillates between the North and South Poles

        Yes, it's also been noted that the frequency of that (rough) oscillation seems to be synchronised with the seasons, weird huh?

        Seriously, the ice at the two poles behaves in totally different ways. Just pause for a second and think about the geography, Antarctica is a land surrounded by deep oceans and a strong circumpolar ocean current, the Artic is a (relatively) shallow sea surrounded by land. Melting at the south pole INCREASES* the extent of the Antarctic sea ice.

        This is because in Antarctica the majority of the sea ice comes from glacial outflows, this ice breaks up with the mechanical action of the waves and floats away as icebergs. Whatever bergs (or ships) that are still close to the coast in autumn become part of that years sea ice. The mouths of these glaciers are enormous and create permanent ice shelves that are several hundred feet thick.

        These ice shelves are the best indicators that the warming trend is impacting Antarctica [wikipedia.org], we are seeing Antarctic ice shelves that have existed for at least 4kys breaking up disappearing at the rate of roughly one a year for over a decade now.

        OTOH Greenland and the Antarctic peninsula have a lot in common and are both effected by something called Polar Amplification [wikipedia.org], a phenomena predicted by the much maligned climate models BEFORE it was observed in the data. There are a whole bunch of such phenomena that were predicted by models and subsequently observed in the real world, "stratospheric cooling" is another well known example.

        In other words sea ice extent is basically meaningless without some context, What you really want to know for the Artic is sea ice volume. I've been following the subject for over 30yrs and the best estimates of volume that I have seen use data gleaned from cold war sonar maps that were declassified sometime in the last decade. According to those figures Artic sea ice volume is now less than 1/5th of what it was when I was born (1959).

        Some (perhaps unwelcome) advise, forget about climate science for now and spend a year or two working on your technical research skills, the best way I know of doing that is to skip church (or some other overrated social club), and spend the time browsing WP and "double checking" the theories and assumptions you hold most dearly. Science is intelligently designed to evolve towards the ideal of "truth" (google "the relativity of wrong" and read it, I can't be bothered to link it). Not only that but for the last couple of centuries the rate of these changes has been increasing over time, Meaning that the older you get the faster it changes, and the more neural archives you will need to update (a personal "theory" that I use to explain my "senior" moments).
        I jumped on the quote above because I first heard it in the mid-90's, I'll concede that on the surface it sounds plausible as it did to me when I first heard it. However as with most of the anti-science "talking points" pushed by a minority group within the FF industry via extremely effective (but surprisingly cheap) professional lobbyists, the theorised "oscillation" soon melts under a skeptical eye. This is why "deniers" don't normally give an alternative explanation. let alone one that stands up to rigor of broader peer-review process. I strongly suggest you use a reputable source [skepticalscience.com] to check out the next climate meme before you infect others with it. As stated in the title your particular meme is #113.

    To put this in some context, have a look at Jim Pettit's "spiral" graphs and consider that the grey zone in the NSIDC plots linked from the summary are still two standard deviations from the norm, and this year we're almost touching that (if that doesn't mean much to you now would be a good time to brush up on your statistics). So compared to last year we've gone from holy shit batshit insane outlier to just plain old holy shit.

        Exactly. This means that the data is bad and you can't change that. Period.

        By the prudent norms of science, this is an excellent first approximation. For the first hundred years, the satellite data will support at most modest convictions. Our accumulated climate record will really hit its stride two centuries from now. And actually, from nearly every perspective of human progress, this represents a tremendous leap over what was known previously. Why should the earth's climate prove easier to decode than Mendel's peas? We finally found the actual genes and we're still pretty sketchy about how they really work. Complicated little buggers they are.

        That said, the satellite data isn't actually bad, it just falls way short of historical norms of scientific prudence. We're stuck wandering around in the uncanny valley between one sigma and five sigma.

        This doesn't mean society can't choose to draw a tentative, intermediate conclusion and act on that basis. However, the consequences of human political resolve are even murkier than the climate science itself, and the scientists can't help up sort this out, unless they have a giant boner for N=1. We have no control planet. Any choice we made can only be compared to counterfactual outcomes grounded in a proto-science itself still slowly gaining clearance from the null hypothesis on its major claim and with error bars a mile wide on the magnitude and immediacy and severity of the presumed effect.

        I think we should be paying plenty of attention to the impacts of climate variability whether or not the cause is anthropogenic. Let's just not put the knee-jerk "all change is bad" types in charge who once decided that forests should never burn. Blockading change is change, too. One of the consequences of embarking upon a global economy is that you soon reach the situation where there's no such thing as somebody else's problem, whether the root cause is anthropogenic or not.

        I have severe reservations about whether it's a good idea to instigate novel political initiatives on a global scale (e.g. abandonment of the hydrocarbon economy) against a back-drop of alarmist proto-facts. Much of the time our best, well-cured, time-proven facts barely suffice to move the political dial in any coordinated way. That's going to radically change over the twenty years? I highly doubt it. Of course, change has to begin somewhere, however bleak the early returns.

        I was reading about some dude yesterday knowingly infected with HIV who had sex with 300 partners, none of whom he informed, and many he lied to. The ultimate self-gratifying scumbag. But what if he only worried he had HIV and never got himself tested? Would he still be a scumbag? Yes, I think so. Even if his worry is only 1.5 sigma? Yes, I think so.

        But if Exxon has only 1.5 sigma belief that carbon emissions could prove disastrous, it's business as usual. "We didn't know!" Not with scientific certainty, anyway, which is unfortunately true. Any certainty worth having is late to the party. This is, however, entirely the wrong standard of prudence and concern. While 1.5 sigma is merely a proto-fact, not yet conclusively proven, it nevertheless demands proper consideration. Facthood in the moment is way too high a standard (and harlot to corporate convenience).

        In retrospect, we will know the difference. Just as we do now about the impact of CFCs on the ozone layer. Whatever doubt remained about this in 1970 is now totally busted. We could confiscate their profits in retrospect. That would make them think twice about not knowing in the first place. I understand that it's bad form to suddenly shout "New rule!" so we could instead begin by suggesting that existing companies take out insurance against future confiscation of profit derived from embarking upon unproven, potentially destructive lines of business—as soberly judged by a future generation with a vastly superior knowledge base (subject to the same hor

          That is WHY it is actually bad. Scientific prudence is no joke, but results from hard-earned experience of heads hitting desks at significant velocities, when it turned out that "scientific discoveries" of confident scientists turned out to be figments of illusion and statistical artifacts.

    We have been heading for the next Ice Age, and a disastrous period of global cooling. It is only by the release of more CO2 that we can save ourselves. Some people with their own self interests (research budgets) are trying to stop that, as well as some people doing so simply because they are pure evil (Al Gore).

        Most of the 'fossil-fuel companies' are actually energy companies now, and will happily sell you solar panels, wind generators, and so on, and be the first in the queue for government subsidies on these things. There's a conflict of interest when they make claims in both directions, the difference is that in one case they are making the same claims as people with less of a conflict.
