Impassable Northwest Passage Open For First Time In History
An anonymous reader writes "The Northwest Passage, a normally ice-locked shortcut between Europe and Asia, is now passable for the first time in recorded history reports the European Space Agency. Leif Toudal Pedersen from the Danish National Space Centre said in the article: 'We have seen the ice-covered area drop to just around 3 million sq km which is about 1 million sq km less than the previous minima of 2005 and 2006. There has been a reduction of the ice cover over the last 10 years of about 100 000 sq km per year on average, so a drop of 1 million sq km in just one year is extreme.'"
I'm sure the Northwest Passage Cruise Line vacation scam spams will begin soon.

What could cause this?
The Northwest passage was first traversed in 1903 by that famous Norwegian explorer Roald Amundsen. This was no small feat given the technology available at the turn of the century.

Plus, those big ships'll have a shorter route on which to belch their nasty so-called "greenhouse gasses" (and will, therefore, not pollute as much!); this could be the best thing to happen to the environment in 30 years!!

Seriously, you have noticed that the world isn't flat haven't you? When planes fly they go north because that creates the shortest route (the grand circle) hence the reason that when flying to Asia the planes often go from Europe straight over the north pole. In terms of mileage this is a massive change (think multiples not percentages) over the existing routes and is the reason why the EU and US are already pushing for it to be an international (rather than Canadian) trade route.
So yes it looks similar on Google maps, but it looks completely different on Google Earth.

Maybe it a troll because there is no -1 "Ignorant enough to kill us all" moderation available?
The race isn't always to the swift... but that's the way to bet!
Let the battle begin......Canada has already asserted complete rights to the passage, Russia and the United States want it to be international waters. It matters because this passage is incredibly lucrative for the months of the year it's open.
That posting is the interesting, I useful fact to carry around.
I'm still a global warming sceptic. I'm all for reducing carbon emissions and the like. I'm just not totally convinved the weather patterns and carbon emissions are intertwined as some of the figures look.

Well, considering the years of study of the Northwest Passage are in the 30's, I'm sure someone will get a little hyperbolic with their rhetoric.
Politics is the art of looking for trouble, finding it everywhere, diagnosing it incorrectly and applying the wrong fix.

This is so wrong I don't know where to begin.
Polar bears have historically required pack ice to breed and hunt. As the ice melts more and more bears drown. Their numbers are in decline. Officially they're listed as vulnerable, but I believe later this year that status will be downgraded to endangered. Hopefully they'll be able to adapt their behavior to the new, warmer conditions of the arctic. But I wouldn't expect that.
There's plenty of scientific research on this subject. Granted, Wikipedia isn't the best reference. But it will give you pointers to look further: http://en.wikipedia.org/wiki/Polar_bear
The blue is growing. White is neutral. All else is shrinking. Notice the LARGE amount of Brown. Just out of curiosity, what has been CLAIMED to be shrinking, but is growing? And do you have some real links, say science mag?
As to you saying that there is little cause for alarm, I would like some links from those in the know. Or are you just BSing like many others here?
Yes, and if you read it, you will see that since the 1970s the population has risen from 5k to 25k. This during a period of alleged global warming. Their numbers are not in decline.

Explorers looked for northwest passage from 1400s to 1900, mapping the artic area. in 1906 Roald Amunsen navigated the passage in an ice-fortified ship. Been done with other such ships since then.
Are you referring to the 1530s and Hernán Cortés? You're jumping the gun a little — it wasn't until 1576 that Martin Frobisher first tried to find the Northwest Passage. Of course, you could be referring to the 1630s as several attempts were made after this to find this passage that did not exist. Perhaps (but surely not) you're conflating the (prior lack of) existence of the Northwest Passage with the satellite record — which only stretches back about 30 years or so. Still, we know that the Northwest Passage has not been passable for well over 400 years.
Now, sarcasm aside, I'm going to go out on a limb and guess that you don't agree with the scientific consensus on global warming. You no doubt extol the virtues of having an open mind and being skeptical. Has it occurred to you that the scientists are just as likely to have underestimated our impact as to overestimated it? In fact, evidence suggests that, being the conservative people that scientists are (not in the political sense, mind you), scientists have repeatedly underestimated our impacts. That doesn't mean that certain non-scientists aren't greatly exaggerating things, but I'm guessing (again) that it's the mainstream science view that you're taking umbrage with.

Read that article carefully to see exactly how he "traversed" the Northwest Passage. It wasn't open then, and hasn't been for at least 400 years (and probably an awful lot longer) — until now.

The first attempt to traverse the Northwest Passage happened well over 400 years ago (did your school not teach this in history class?), and several attempts have been made since then. This is the first time that it's been open as far as we know — and not for a lack of looking for it. I love the uncertainty and doubt, though — perhaps you can find some fear now?

Nobody claimed that Amundsen has not done it back then. The claim is that the passage now is practicable in one go, because the whole passage is open. Amundsen needed several years to make it all the way through in bits and pieces. And he couldn't have done it in any larger ship than the one he used, due to the water water being as shallow as 3 feet. Not exactly an economically viable solution.

... massive change (think multiples not percentages) over the existing routes and is the reason why the EU and US are already pushing for it to be an international (rather than Canadian) trade route.And why should Canada's sovereign territory being pieced apart? If it suddenly became globally advantageous to cross shipments through most of the US, the EU and the rest of the world would be perfectly justified in making it international territory as well?
You people can just fly/ship your people/things with our blessings (and taxes), the land and airspace belongs to us.
Try reading up on the history of the Northwest Passage. Sure, we've only had a complete meter by meter map for 30ish years, but we've known about the lack of a Northwest Passage for centuries.

Requiring an icebreaker to get through means that the passage wasn't really open (not that you're disputing that, but some on this thread can't quite seem to grasp the difference here).

"I've got more toys than Teruhisa Kitahara."
What would be coincidental about it? Yes, the world is getting warmer. Everyone agrees with that basic statement. Now tell me _why_ it's because of Mankind. We already have geological proof that the world gets hotter and colder in cycles and we are (geologically speaking) getting out of an ice age. And I want hard numbers, like "23% of global warming compared to the mean of the last decade is due to CO2 emissions from the following nations" etc.
I do not respond to cowards. Especially anonymous ones.
If there was anyway to definitely prove it. We don't know anything about the entire passage prior to 400 years ago, but people have been interested in trying to find a way through continuously since then. If the passage in the last 400 years was ever as wide as it is now, it would have been easily spotted. Have you seen the satellite pictures? Here's a source that has a history for this summer.

You are jesting, surely.
If you had any idea about the condition of the merchant ships and the way their crews are hired, you would have never said that.
Deep sea marine merchant fleets are governed by something which can only be described as a "law of the jungle", where the disposable crews (literally! I heard stories of men simply dumped in the next harbour, regardless of location, after losing arms or legs in accidents on the ship, without any concern about their means of medical care or transportation. Insurance? You gotta be kidding!) and rust-covered ships worked until they literally fall apart at sea, after which the owner simply collects more then their value, having shrewdly adjusted the insurance payout in anticipation. Any attempts at regulation usually result in the owners re-registering all of their ships in places in which bribery, corruption and non-existant regulation make up for an "ideal" merchant shipping home port. What did you think the words "flag of convenience" mean? Ever notice that all of those ships in the news which broke up on some rocks are flying weird flags from strange places, even though they are clearly owned by western conglomerates?
Adding nuclear power to this mix would be truly suicidal.
Now tell me _why_ it's because of Mankind. We already have geological proof that the world gets hotter and colder in cycles and we are (geologically speaking) getting out of an ice age.
Smoothness. Just take a look at the curves, and you'll see lots of cycles, big and small but these are changes that happen over thousands (and in some cases, millions) of years. What we see today is much bigger than "the little ice age" and the yearly variations, it goes straight up and coincides with our industrialization and CO2 emissions. Just because our ability to accurately predict say a storm center months in advance is poor, we know what normal variation is and this isn't it. You seem to want proof on the level of "beyond any reasonable doubt". Personally I think those that are willing to risk destroying the planet on the off chance that "it might not be us" are should err on the side of caution, not suicidalness. YMMV.

Actually, having the Chinese, as well as all other nations, being well off frightens only the proponents of "globalization" (who are usually some variants of "conservative" these days - although any greed blinded individual will do) which hypocritically, depends on vast inequalities which can be exploited for profit.
Wealth and responsibility are not mutually exclusive.
The answer of course is to enable other nations to grow sustainable economies, centered around local products and services.
"Globalization" as it is envisioned and conducted at present is the bastard child resulting from an orgy of greed and colossal waste, orgy conducted with gleeful, utter abandon and contempt for the future generations.
It is the crowning achievement of the "I got mine, so Fuck You All!" world-view
To be fair, your point has one valid element: the Western working class is just as guilty of in this very attitude as the Western business elites, and so, by extension, also complicit in this. Only now do they realize the true implications of their short-sighted political apathy.

Consider another glacier - a really big one with a lot of ice behind it and a large height difference and/or steep slopes. Something like this moves faster. When it gets warmer it will move faster again. These are the glaciers that are advancing.
Unfortuantely we have people that really just want to win an argument that just take the amount of advance and retreat of a lot of glaciers and average it without considering why. They are completely ignoring the temperature measurements in those locations since they are pretending to use a glacier as a thermometer instead of the real thermometers that may actually be there.
As for the warm is good argument - I recommend talking to a farmer. Whether it is a El Nino or La Nina effect in the Pacific in a paticular year is enough to drive farmers backrupt off the land in some areas - they know about warm weather in the wrong spot.
I'll have to say I agree that we're, geologically speaking, still getting out of the last ice age. We haven't started the next one yet, and there's still plenty of ice around, so you can't really say we're done with this one.
You'll also notice, from your graph, that the global temp is actually lower than a number of the previous spikes (showing that as far as that graph is concerned we're NOT warming anymore). You'll also notice that while it's not going down, it's steady (which doesn't show the continuous upward trend that news sources want you to believe). You'll find in your noted graph, on the left at around 425,000 years ago there was a similar leveling, which was followed by a spike and then a drop off in temp.
Now I'm not going to say that all of our CO2 emissions are helping things, but I would like to point out that the earth was doing a fine job spiking it's own temps long before we arrived. Volcanos, changes in the Earth's orbit around (Milankovitch cycles), changes in plate techtonics, solar output and meteorites have been deciding factors before and likely will continue that way in the future. I'm assuming they don't teach this stuff in school anymore, so here's a link http://en.wikipedia.org/wiki/Ice_age.
I find it #1 vain of the human race to think that they're the ONLY reason why temps can change in the world, #2 to think that they're the only thing that can fix it, #3 to think that this hasn't happened before and won't happen again. Humans are but a blip in the geologic time scale.
That being said, there are plenty of other reasons besides global warming to go green, we will run out of oil sooner than later, and land/water pollutants cause more harm that CO2 anyway. Let's not be so one sided and try to come up with ways to make things better for the environment as a whole instead of throwing everything towards "global warming".

"It was a whole lot warmer in the last interglacial, 120kya...balh, blah, blah"
It's not the temprature itself that people are concerned about (go back 250MYA and CO2 concentrations were 4X what they are now and the planet was 10C warmer. It's the unprecedented rate of change that is "unatural" and a "clear and present danger".
The melting of the North pole was predicted and it is now undeniably occuring, one of the predicted "flow on effects" of an ice free Artic ocean is desertification of midwest US ( modern humanity's "breadbasket"). Perhaps you would be happy to return to foraging for grubs and shellfish or hearding goats in an arid wasteland (re: middle east), me - I'm kinda fond of the idea of growing our staple diet in a predictable and sustainable manner. If you think discussing the possiblity of a global famine is hyperbowl then take a good look at what is happening to SE Australia (where I happen to live), if you prefer history then take a look at the "dustbowl" years in the US or the many cases where ancient civilizations crumbled due to rapidly changing environmental conditions. Not to mention global fisheries have been collapsing like dominoes since the 1980's....opps - I just did.
Currently the Artic is predicted to be ice free in 40-50yrs so (according to predictions) the US still has a while before it "dries up", but this year's data (to quote TFA) was "extreme". I have no idea what a 25% reduction from last years record low does to the statistical trend or the predictions of when (no longer "if") the Artic will become ice free in the summer. However using the figures from TFA, if the next three years are as "extreme" as this one then the ice will have receded into oblivion before kyoto even comes up for renewal in 2012.
"It's no mystery."
It is a huge mystery but it's not a total mystery thanks to thousands of scientists who have been very actively working on the broarder question of the "dynamic stablity" of the biosphere in general and climate in particular. Thanks to this large but much maligned group of boffins there have been huge strides in our knowledge over the last three decades (including the sources for your "facts"). Yet when the consensus predictions of these "grant seeking leaches" start occuring in front of our very eyes at a much more alarming rate there are still those who will brush it all aside with some self-serving babble about our distant ancestors who had not even developed language let alone a global econmy and infrastructure that is TOTALLY dependent on the predictability of annual weather patterns (ie:climate). Arguing about the exact definition of an "open" as it pertains to the N.W. passage is the preverbial arranging of deck chairs.

Am an in awe of your grasp of the situation, specially when highlighted with such creative epithets. Now, do please explain how does this hypothetical fleet has its maintenance and hiring practices improved, given that vast majority of it is registered in, say, that bastion of high standards of regulation: Antigua, and owned by companies registered in, say, Dubai. For a bonus question: explain away your method of forcing the merchants to use the astronomically expensive (in relation to everything else) nuclear reactors followed by your gracing us with your enlightening views on the methods of securing the nuclear fuel and the ships themselves from falling into the hands of some bearded and beturbaned individuals with somewhat antisocial attitudes.
I am reeling under the assault of your great wit, so cleverly based upon words of "shit" and "pig". As to being blindly "grafted" on an aspect of reality, I am afraid I got you beat there, since your entire rant consists of "hypothetical" hot air, which does not even withstand most cursory of "hypothetical" searches for traces of common sense.
