Arctic Ice Cap Rebounds From 2012 — But Does That Matter?
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.
Looking at a single year doesn't tell us much about the trend. Here is some real data.

Pointing at year-to-year variations in order to prove or disprove a phenomenon that has a time-scale of decades is stupid, no matter which side of the argument you're on. This is like saying you don't believe winter will be cold, because the weather is actually warmer today than it was last week.
Or it could be that the whole AGW platform has been hijacked by those pushing "cap and trade" who will make a mint thanks to the scam being written by the ones who came up with credit default swaps, 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.
ACs don't waste your time replying, your posts are never seen by me.
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.
ACs don't waste your time replying, your posts are never seen by me.
More like business as usual for the deniers. 60% up from 75% down is still way down, let's do the math:
Start with 1. 1-0.75 = 0.25. 0.25*1.6 = 0.4. So, even after the rebound we're still 60% down.
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.
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 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, 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.
So to summarize, this was expected, and predicted, and no models will have to be changed based on this observation.
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, 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, 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 to check out the next climate meme before you infect others with it. As stated in the title your particular meme is #113.

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?
Posted from my Android phone. Oh, I can change this? There, that's better...
Carbon taxes will do nothing in the face of exponential population growth.
Which is why you want to be educating women, as that seems to be the most effective mechanism for reducing population growth rates.
