NOAA: Arctic Likely Free Of Summer Ice By 2050 — Possibly Much Sooner
Scientists from the National Oceanic and Atmospheric Administration have published research into the shrinking levels of sea ice in the Arctic. They wanted to figure out how long it would take before summer sea ice disappeared entirely. Since there's no perfect model for predicting ice levels, they used three different methods. All three predicted the Arctic would be nearly free of summer sea ice by the middle of the century, and one indicated it could happen as early as 2020. Two of the methods were based on observed sea ice trends. If ice loss proceeds as it has in the past decade, we get the 2020 timeframe. If ice loss events are large, like the 2007 and 2012 events, but happen at random some years, the estimate is pushed back to 2030. The third method uses global climate models to 'predict atmosphere, ocean, land, and sea ice conditions over time.' This model pushes the timeframe back to 2040 at the earliest, and around 2060 as the median (abstract). One of the study's authors, James Overland, said, "Rapid Arctic sea ice loss is probably the most visible indicator of global climate change; it leads to shifts in ecosystems and economic access, and potentially impacts weather throughout the northern hemisphere. Increased physical understanding of rapid Arctic climate shifts and improved models are needed that give a more detailed picture and timing of what to expect so we can better prepare and adapt to such changes. Early loss of Arctic sea ice gives immediacy to the issue of climate change."
Climate can change and it will change but predicting these kinds of trends to 2050 with any kind of accuracy is ludicrous at best, since they cannot even predict whats the weather next weekend.
Long-range climate predictions are nearly always wrong, despite their insistence to the contrary, I suspect they may be wrong again.
Or not...

The only chance (and it's a damned small one) of getting the various political entities motivated to actually do something is for major shifts to happen in a time frame so obvious that even Rush Limbaugh can figure out there is an issue. If the Arctic weather system collapses, pushes the jet stream away and lets Europe freeze ...
Damn it again.
That'll just confuse them even more.
We're doomed.
Faster! Faster! Faster would be better!
Do you know how long we've waiting for the Northwest Passage to open up? Finally we will be able to move goods between Europe and Asia in weeks rather than months!
There are other models that are based on solar modulation having to do with orbits and magnetic field strength. According to them, we're going back into the deep freeze 2020-2040, so don't worry about it.
I will be able to water ski from North America to Russia, always wanted to do this.
Professor Wadhams at Cambridge already predicted the collapse by 2015. Here is a reference. This site predicts 2030 at the latest.
Climatology isn't a dart board, you don't make a ton of predictions and then claim you are right when one of them hits. You go back and do further research to understand the climate better.
"First they came for the slanderers and i said nothing."
One approach looks only at ice volume measurements, and explicitly ignores theory because the existing theoretical models failed to predict anything like the ice loss that we observed. Using the simplest accelerating-curve-fit, we get first ice free in September 2017, and six months per year ice free by 2025.

There is no global warming, enough of this $HIT, Slashdot.
Arctic ice extent is normal. Look at the DATA not the propaganda doomsday soothsayers claims.
"From 1988 until a few years ago, a lot of multi-year ice was getting transported into the North Atlantic during the winter. This caused a large drop in the thickness of the ice. What they don’t want to talk about is that this pattern has reversed. The amount of multi-year ice is increasing since 2008, and during this past winter almost all of it moved west towards the Beaufort Sea, where it will slow summer melt."

"Climate experts tell us that the poles are melting down, which is why global sea ice area is eighth highest on record for the date."

Or in 10 years or in 20 years or the year after that or.... quiet please!
trying to stop this, we should be spending it on working out how to deal with the issues.
If current trends continue, negative sea ice in 2040, and an entire negative ice cap by around 2080. Next up, negative ice age!
I'd trust climate models a lot more than extrapolation, though both are likely pretty inaccurate; at least the level of inaccuracy is estimated and stated.
it's no longer a discussion,
Climate change will happen - the only question is how much more extreme will future changes be?
I'm mostly interested in how evolution will be effected? Especially homo-sapiens? So little environmental changes brought humans here and even - much more recently has lead to racial difference.
I'm eager for the future...
some good climate change content will help justify the NOAA and get the research scientist's team continued funding.
I would be very worried about this prediction. Luckily all the Global Cooling they predicted earlier will cancel the Global Warming out.
The only chance (and it's a damned small one) of getting the various political entities motivated to actually do something
The United States at least, is done. We have hit Kyoto targets. If that was going to help, then it should help; otherwise obviously no further reductions will help much.
If you truly believed what you say, you would be heavily pushing for fracking and nuclear energy. But we both know that's not going to happen, so take your hypocritical and obviously mindlessly liberal (trigger word: Rush) stance and try and scare someone else. The rest of us can think for ourselves.
In the meantime, if there were really a crisis all sorts of leaders would be eschewing personal jets and other things that emit far more carbon than I will in a lifetime. When people in power start acting like there's a crisis, instead of just claiming there's a crisis - at that point I'll put some credence to there being a real problem that needs addressing.

The most unambiguious measurement of arctic ice at the moment is from the GRACE satellite (Gravity Recovery and Climate Experiment), a satellite that is measuring the mass of ice on the poles.
These results do not support your statement "the amount of multi-year ice is increasing." In fact, it is significantly decreasing
http://www.nasa.gov/mission_pages/Grace/news/grace20121129.html
http://www.nasa.gov/mission_pages/Grace/multimedia/chart20121129.html shows the graph.
Here's an animation showing specifically the data from Greenland: http://photojournal.jpl.nasa.gov/archive/PIA13955_Greenland_Ice_Loss_20111205-640.mov
http://www.geoffreylandis.com
We took a look at past average temperatures and plotted the standard deviation and where the last 10 years of temperatures lie. The odds of this being a natural trend basically exceeded the age of the universe.
I swear to God...I swear to God! That is NOT how you treat your human!
Hardly liberal. If you think that most conservatives like Mr. Limbaugh you live in an especially special place.
No, frakking isn't going to help much of anything except give us a few years before fossil fuel costs really go through the roof. It's not going to help unload the excess carbon from the environment. Natural gas is only marginally 'greener' than coal. Not enough to matter.
Nuclear power is another subject. IF we could do it correctly (better siting, upgrading, monitoring and decomissioning of plants as well as some sort of half reasonable way to deal with waste) it would be fine. Since we seem to be doing none of those things and since even solar and wind are cost comparable to nucs, it's not much of an answer, IMHO.
Kyoto was a bad political joke and had little to do with slowing global warming. It was simply a test of political will and as such, failed.
And yes, if humans, especially those in a 'leadership' position did something other than try to outrace the next guy in terms of carbon consumption it might help. However, the real problem is the several billion people trying to work their way up from dismal poverty to something better and scooping up all sorts of resources in the process. Can't say I blame them, but it is causing enormous, intractable problems.
All in all, Homo Industrialis won't deal with this problem very well. But it will get dealt with. It's just going to be ugly, protracted and scary.
Faster! Faster! Faster would be better!
They need those jets to tell us plebs about the crisis. I also enjoy that a solution to stopping climate change is higher taxes.

Once the ice age is finally completely over, Greenland can once again become a booming botanical powerhouse, as it was 25,000 years ago.
Imagine the possibilities once Greenland becomes arable again.
The Arctic ocean is warming up, icebergs are growing scarcer and in some places the seals are finding the water too hot, according to a report to the Commerce Department yesterday from Consul Ifft, at Bergen, Norway.
Reports from fishermen, seal hunters and explorers, he declared, all point to a radical change in climate conditions and hitherto unheard-of temperatures in the Arctic zone. Exploration expeditions report that scarcely any ice has been met with as far north as 81 degrees 29 minutes. Soundings to a depth of 3,100 meters showed the gulf stream still very warm.
Great masses of ice have been replaced by moraines of earth and stones, the report continued, while at many points well known glaciers have entirely disappeared. Very few seals and no white fish are found in the eastern Arctic, while vast shoals of herring and smelts, which have never before ventured so far north, are being encountered in the old seal fishing grounds.

it's in my head
You pick the year, they pick the theory. This year next year every years a winner. So basically they dont know and need more funding to narrow it down. Maybe next go round it will be odd numbered years, 2025, 2035, 2045.
And how far back did your past data go?
Except for ending slavery, the Nazis, communism, & securing American independence, war has never solved anything.
How quickly can you say BS?
The past three universes. Then their records got a little fuzzy.
Is the next real estate bubble.
"This collapse, I predicted would occur in 2015-16 at which time the summer Arctic (August to September) would become ice-free. The final collapse towards that state is now happening and will probably be complete by those dates"
"Too late"??????? WHAT THE FUCKING FUCK WHAT????
And did you read this bit? "and will probably be complete by those dates"?
No?
What about the volcanoes on the Gakkel Ridge. All the warm water held in the Arctic basin should be contributing to some or even most of the loss of Ice.
I have seen data showing the slow increase in Antarctic Ice versus the slow loss in Arctic Ice.
I tend to be a skeptic on all end of the world scenarios, until an asteroid or comet are heading in our direction.
"Endeavour to persevere"
No?
I didn't think so.
Sigh...
You: Erm the accuracy of predicting a single coin toss is THE SAME as 1000 coin tosses.
In response to: the results of 50 or 100 or 1000 coin tosses in ensemble.
U niid skooling.
What about the volcanoes on the Gakkel Ridge.
The comment I was replying to stated that the decrease in arctic ice thickness "has reversed." That statement is not correct, and I posted a link to the data.
Now you, apparently, are trying to come up with a hypothesis to explain this, other than the trivial hypothesis that since temperatures are increasing, ice is melting.
Fine. Do some back of the envelope calculations, and if you still think that's a viable hypothesis, well, uh, maybe you should get somebody else to check your calculations. Then, if you still think it's plausible, go get your ice model peer reviewed.
...
I tend to be a skeptic on all end of the world scenarios, until an asteroid or comet are heading in our direction.
This majorly pisses me off. I point out data showing that Arctic ice is thinning, and people jump immediately to "he's screaming about the end of the world"! That's a false dichotomy: either carbon dioxide has no effect on climate and everything's fine, or it's the end of the world, no other alternatives.
The planet is warming. This is very well documented. "End of the world"?? Why does everything have to be "it's the end of the world"? It's not the end of the world.

No, frakking isn't going to help much of anything except give us a few years before fossil fuel costs really go through the roof.
The U.S. alone has hundreds of years of natural gas reserves.
Natural gas replaces coal power plants, which emit tons (literally) of CO2.
Nuclear power is another subject. IF we could do it correctly
What "if" is there? Even if you run the most leaakingist explodingist mutation causing nuclear reactor ever fired, you still are emitting zero CO2 compared to whatever else was providing energy that the nuclear plant now provides. Is CO2 caused global warming a crisis or not? If you really thought it was you be willing to accept ANY amount of localized pollution in exchange for not having a climate too hot to support life. So we can pretty obvious understand from you and other people's take on this that CO2 is actually of zero concern whatsoever.
Kyoto was a bad political joke and had little to do with slowing global warming.
Yes it did fail, that is not my point. My point was that it had a TARGET of CO2 levels to meet that was supposed to address the problem. The U.S. has met the target, supposedly set by real scientists. If those targets are not good enough, then what IS a target the U.S. should meet and where is THAT target from? Is the target zero? I get the sense the only answer you and other hopelessly unrealistic warming cultists will accept is zero, with the same percentage of scientific backing behind it.
However, the real problem is the several billion people trying to work their way up from dismal poverty
To the environmentalist, it always comes down to somehow mandating a certain portion of the populace must be kept in squalor "for the good of the Earth". Or I guess we could just hitler them (oh no I DIDN'T)!
Disgusting.
But it will get dealt with. It's just going to be ugly, protracted and scary.
It sure will be scary having greater yields in agriculture across the planet! I shiver! Or I would if it were cold anymore, which it isn't what with winter everywhere being a thing of the past (as they were saying about the UK some years ago). Going to pack a bathing suit and visit Europe next January. Or should it be ten Januaries from now? Or 100? Or 1000? I'm a little fuzzy about that exact rate of warming again...
"There is more worth loving than we have strength to love." - Brian Jay Stanley
The time to act on global climate change is now. We shouldn't worry about whether it is man made or not, but instead we should worry about how we can get to the point to where we can change the climate in a ten year time period. Since we can't agree whether CO2 is the problem we have to agee in a diplomatic fashion how to stage it so that action can start at a moments notice. I would suggest that we develop climate altering technology to the point that we are ready for full deployment. In order to do that we need to develop, test deploy, do full end to end cost studies, and prepair the infrastructure necessary to roll out climate altering solutions in a time frame that will allow us to rapidly turn the climate around. Investing in short term solutions like pumping the atmosphere full of volcanic gasses, and long term solutions such as air carbon capture require lots of planning, and testing. We can pay for it with the trillions made from recycling the worlds plastic and the rest of the MSW that we generate and clean up the environment at the same time. That is a no brainer we can all agree on. See my articles on the subject atrawcell.com under the top menu.
How?
The maximum odd is 1.
So unless the universe is less than 1 in age this isn't even remotely possible.

In a rider to the a bill to fund the Postal Service, a little know rider was attached.
Having passed, although the Federal Government is still under yet another continuing resolution,
the rider bared any Federal scientist using travel funds to attend national or international conferences.
What is in play is Authoritarianism. Scientists employed by the USA Federal Government are 'worker
bees' and nothing more. As such, 'finding of fact' whether bogus or legitimate can only be issued by
the President of the United States of America. So, the Arctic sea ice 'WILL' disappear by 2030 [roundabout]
and this pronouncement is by the President of the United States of America through his organ of choice,
this being the National Oceanic and Atmospheric Administration (NOAA). Given the track record of NOAA
which by the way was instituted by President Richard M. Nixon, is quite lacking in any significant detail as
to give confidence of the Presidential Proclamation of the demise of the Arctic sea ice for all eternity thereafter
at a sufficiently telegenic berth on the shore of the island of Spitsbergen.
Counter attacks on Authoritarianism governments are most productive relative to Fascist governments.

I'm seeing a lot of stories about unseasonably cold weather all over the world.
The idea of Global Warming seems rather thin at the moment.
I'm guessing that the centralist planners who want to implement population control measures through BS excuses and fairytales about human controlled environment (for good or bad) just picked the wrong horse in the race. Shoulda said 'glaciation' instead of warming.
It's all crap, and it's not in under our control, and that knowledge is what the elites fear. They know on the gut level that if the 99% thinks the kings and emperors can't pray fast enough to the gods of the sky that we tend to chop their heads off.
Mob rules, and that's why they're all about the population control measures and misdirection. The mob is damned scary when it gets roused and there aren't enough bullets in Texas to stop us all if we stampede.
The Arctic might actually be put to productive use. I will not give up my pickup truck!
an ill wind that blows no good
http://exhibits.museum.state.il.us/exhibits/larson/LP_extinction.html shows a couple of maps of glacial retreat. The past few years are merely the logical continuation of a ice cover retreat that's been going on for the past 18,000 years. Yes, there have been a few speed bumps along the road (e.g. Younger Dryas and Little Ice Age) but the macro trend has been decreasing ice cover for the past 18,000 years.
And 18,000 years ago, the planet's total human population was approx a million people. http://en.wikipedia.org/wiki/World_population#Antiquity_and_Middle_Ages They weren't running around in CO2-spewing SUV's. So we must agree that the retreat of the icecaps for most of the past 18,000 years was not caused by human civilization. Why is it suddenly humanity's fault today?
I'm not repeating myself

Look at the state of the U.S. and for that matter the world's economy. Sucks doesn't it? Misery all around, right?
And it took this kind of downturn to get us to the Kyoto levels which you claim are a joke.
So just think how bad the economy needs to get before we reach your mythical levels of reduction that ARE designed to slow global warming.
Nice, eh?
The Russians have a temporary Ice Camp near the North Pole for the month of April. The first base camp started in 2002.

Just like in the 70's when they were screaming about the impending Ice Age and how ICE was going to be clogging all of the Northern Port Cities - now it's Global Warming... Anything to get idiots who cannot read a thermometer to pay more money for things and get people willing to jack up the price of energy. They've been trying to do that for the past 40 years... Now they just say it's all Global Warming - temps nose-dive, it's Global Warming, temps climb, it's Global Warming...
How about we mark it up to Stupidity of large numbers of People and call it good... They can fret and worry, I'll pass...
Or a big refrigerator.
Vote monkeys into Congress. They are cheaper and more trustworthy.
Fools call it climate. Shucks folks, even your weatherman cannot get it right consistantly. And their models are for your local weather. But in NASA's wisdom, in the name of the gd of cst savings, they threw away all the working models, that were working to predict the weather, at 90% or better accuracy and have gone to models with a lot worse accuracy. Look at the weather bureaus rate of accuracy now, at one week, to seasonal. wrong models. That affects/effects all of your lives. From planting crops, to harvesting to your daily commute. To me, thats sabatoge. Thats a crime. But just like the bankers, ...
So we justify anothers death in the name of another dollar saved...
And they call themselfs christian...
Put an icecube in a glass of water. As it melts the water level will not change because the ice cube displaces the same volume of water as the amount that melts. In In the same way, sea levels will not rise even if all the ice on the sea melts. Check this video for an example. Nothing to see here, move along and thank you science!
Whenever you read a DIRE prediction about anything, you need to translate this immediately to:
Budget battle underway, cut in funding is imminent, must create panic now.
This has been going on ever since Governments started handing out your money to people who's ideas weren't good enough to survive in the free market.
I predict that in the next ten years, people will continue to shout their ideology at each other while claiming to understand science, physics, and math better than the other guy. People will believe damn near anything if it's dire enough, worrisome enough, and has the end of life as we know it associated with it. Double this effect if some amorphous entity is setup as the straw man to be hated and despised, particularly if the believer can be convinced that these entities have it better than they do. The more emotion, the more proven the "science". The simple fact that GREED is one of the most powerful of all human forces next to LOVE is lost on many people. A FEW people here get this, and they are to be commended. I'd wager they are older than your average "The World is going to End unless" folks.
Murphy was an optimist
I think if you analyze the amount of heat energy volcanoes emit compared to the amount of heat energy required to effect the changes we've observed you would find volcanic heat is totally inadequate to explain the melting.
Climate change gonna come at last
Now your icebergs are meltin' fast
That's right. The warming that we've seen for a few decades has stopped and we will be back to our normal "ice age" self sooner than you think. CO2 is not the control. EVERY SINGLE prediction made by the warming camp has been shown to be WRONG. Their models are garbage. Expensive garbage but still GIGO.
Yay, more info to make the liberals and eco-crazies tell the rest of us how we must live in order to save the planet at the expense of our bank account and/or our comfort. We are more worried about the so-called issues the polar bears are experiencing than we are about the million babies aborted each year, which is REAL, not propaganda. Anyone who believes this is actionable info has their priorities messed up.

Who's bright idea was it that it's a 'good thing' our planet is frozen solid almost perpetually above and below certain lattitutdes? During the time of the dinosaurs there were no polar ice caps and the world was much hotter than even global warming predicts we could get. Was the planet one big smouldering desert that killed off tons of species? Nope. It had a higher biodiversity than we have ever seen in mankinds entire history. Storms were no worse than they are today, more of the available land was habitable, and life THRIVED.
Ask me if I'm afraid of global warming, go ahead, ask me.
No.
If the Arctic starts to become ice free in the summer months it will allow for unprecedented access to the ocean, open up shorter, cheaper, more environmentally friendly trade routes for ocean vessels, not to mention exploration of the ocean and it's depths.
Now if we could only thaw out Antarctica too then we would really be moving along. Yeah we might lose a little coastline around the planet but the rise would be gradual and we would adapt. Remember Jamestown, North America's first settlement? Underwater right now. The fact is that coastlines already change even within a few generations, why be worried about loosing some more? The earth isn't going to flood, it's not going to e a 'water world'. Were the dinosaurs underwater? Nope.
Antarctica is an entire continent that is virtually inaccessible and unexplored. Underneath millions of years of snow and ice is an entire land waiting to come free of a million year deep freeze complete with new mountains, lakes, not to mention habitable land. Who knows what we will discover locked beneath the ice there. It makes me excited.
So don't worry, learn to enjoy not having thousands of people and millions of dollars in lost wages and damage every year from severe winter weather, and uh yeah. We get to go swimming in December, a reward for returning the earth to it's natural state of not being frozen solid year round.
No, your assertion is completely made up.
