Permafrost Loss Greater Threat Than Deforestation
Pierre Bezukhov writes "Emissions from thawing permafrost may contribute more to global warming than deforestation this century, according to commentary in the journal Nature. Arctic warming of 7.5 degrees Celsius (13.5 degrees Fahrenheit) this century may unlock the equivalent of 380 billion tons of carbon dioxide as soils thaw, allowing carbon to escape as CO2 and methane, University of Florida and University of Alaska biologists wrote today in Nature. Two degrees of warming would release a third of that, they said. The Arctic is an important harbinger of climate change because the United Nations calculates it's warming at almost twice the average rate for the planet. The study adds to pressure on United Nations climate treaty negotiators from more than 190 countries attending two weeks of talks in Durban, South Africa that began Nov. 28."
Based on their inaction and their stated desire for inaction: Canada, Russia, and the USA.
If clathrate gun hypothesis is correct, the things may become interesting during our lifetime (which may be a shorter one).
Questions raise, answers kill. Raise questions to stay alive.
Permafrost makes it harder to dig, hurting the economy and killing jobs. That's why everyone hates it.
To offset political mods, replace Flamebait with Insightful.
Arctic temperatures are *not* rising. The data is flawed because the sensors are all set up near Santa's Village, which has been experiencing massive growth over the past few decades as increasing numbers of spoiled kids get more gifts each year. The resulting urban heat island effect (amplified by primitive and inefficient elven HVAC technology) has severely skewed all the Arctic numbers, and the rising temps are just an illusion.
Because 1. Man is influencing the climate, 2. Most of this change is going to be bad, 3. There is no political or social will to change our current behavior, and 4. Once shit hits the ecological fan, those with resources will shield themselves from the effects and those without resources will be fucked.

Doesn't this mean that the sterile wasteland that is permafrost would also come back to life again? I thought more life, especially plant life, was a good thing?
One of the commenters mentioned marshy bog. Isn't that one of the precursors of peat and coal?
As the globe continues to warm, eventually the Northwest Passage will be a viable route for less ice-hardy vessels more times out of the year, providing economic benefit for those who could utilize the shipping routes. I imagine there are lobbies that would love to see this happen. This is speculation, for I do now know if people actively encourage warming. Looking at the CO2 data and its positive correlation to the mean global temperature increase, it seems we may see that route in our lifetime.
Also as the permafrost disappears, another side affect is a cascading result in the loss of surface ice/snow pack. As the surface area of the snow/ice/arctic shelf shrinks, the Earth's regional albedo will be reduced, ie there will be less radiational cooling and more energy absorbed by the surface. Cycles such as this create feedback loops in the environment that cause these affects to amplify. Lower albedo -> less permafrost/snow/ice/glacier coverage -> more heat -> lower albedo -> ad inifinitum.
I am not a meteorologist, but based on some cursory research these seem to be realistic eventualities.

If nothing else, soft-science and government types get a taxpayer paid trip to South Africa for 2 weeks. Do you think they really want to FIX global warming?
I want to delete my account but Slashdot doesn't allow it.
The study adds to pressure on United Nations climate treaty negotiators from more than 190 countries attending two weeks of talks in Durban, South Africa that began Nov. 28.
I would agree with you, except that we can expect to see exactly the same thing that came out of the last UN climate summit... And the one before that. And the Kyoto accords.
Namely, nothing. Politicians act on a scale measured by the next election cycle (and can't even manage that lately). I have absolute confidence that our "leaders" will do nothing whatsoever about climate change until they get to feign surprise that all their precious coastal cities seem to have started taking on water - At which point, they'll blame the other party and still do nothing.
We have calculated the one-time pulse of CO2 released by thawing. Will the newly arable land not host new carbon absorbing growth into the indefinite future? Perhaps that's how all that carbon got stored there in the first place.
I wonder if this is one of the mechanisms that prevented the Earth from becoming Venus during the last 800 million years of Nitrogen/Oxygen atmosphere. Lord knows I'm left to wonder; I have yet to read a single story about any feedback mechanism that isn't hellbent on destroying the planet.
Think about Alaska, think about the size of Alaska, now, cover it in a layer of mossy stuff several feet thick. That mossy stuff is muskeg, and if you've ever stepped in a soft spot in the muskeg and sunk up to your hip in the muck, you can easily imagine the whole thing decomposing into methane when it gets warm.
It doesn't cover all of Alaska, but then, it's not only in Alaska, it's also all over Canada and Siberia.
Oh well, the polar bears didn't drown, the Antarctic didn't defrost, New York hasn't been inundated, so now we're down to defrosting the Arctic? Based on some bogus "calculation" by the known frauds at the UN. Yawn, wake me up when the world ends.
Go ahead and stay home from school. The world needs ditch-diggers too.
Hard digging is good for jobs. :)
Help stamp out iliturcy.
Let's see - France has better looking women, better food, better wine, better movies and better art, and has been a world leader in aeronautics since Bleriot through Arianespace and Bleriot. Their mintel predated and pioneered the idea of a pervasive online service, they've made tremendous contributions in math. And even though they took it on the chin from Germany in World War II, they had incredible artillery and aircraft in World War I, and previously, pioneered everything in engineering from steel warship construction in the La Gloire, and finally, they gave us mayonaisse.
This is my sig.
If you had ever been really, truly cold, then you would understand why the folk in Canada and Russia could really give a damn that global warming is flooding your Florida swamp real-estate.
So, without further ado: The Cremation of Sam McGee.
Help stamp out iliturcy.
1) And the US has a metric shit ton more resources than Germany. Your point?
2) You fail basic economics. If the mark or the euro are overvalued, exports are terrible because they're more expensive than local goods. Try again.
3) A declining population has nothing to do with economic greatness. Unless you're thinking immigration - in which case, the US is trying real hard to come down to Europe's level.
4) You know squat about German corporate taxes, squat about US taxes and even less about real corporate taxes that arise from such niceties as the dutch sandwich or various indirect contributions.
5) You also know squat about the German university system. Anyone can go to University, except those who keep failing their High School classes. Those that do fail classes go to technical trade schools. It's exactly like the US system, except it's predicated on grades rather than money.
6) Your choice.
7) You're making a lot of assumptions about future events. Would you also like a pony?
8) No idea how that bit of (factual, for once) information relates to how well Germany is doing.
9) Yes, you can get fancy food all over the place. That said, I'd rather walk into a random Braustaette than a random American diner.
10) Your info is about 3 years out of date. In the meantime, the Porsche Panamera bettered the laptime by about 4 seconds.
There are a ton of reasons why Germany has a ton of problems and is worse than the US, but for some reason, you managed to barely allude to only one in your list of ten.
Those who can, do. Those who can't, sue.
An overvalued currency harms exports - it makes your prices higher than those of places without overvalued currencies. (And nothing is overvalued relative to the US dollar - well OK, US treasuries but those are really just future US dollars anyway).
So your logic has Ethiopia, Liberia, Somalia, etc. as being "greater" than the US? And Luxemburg and Turkey have faster growing populations than the USA so your facts are wrong too.
15% business tax + 15% corporate tax + 5.5% solidarity tax is much lower than a 15-35% federal + 0-12% state progressive scheme? That would depend entirely on which two locations in the countries you are comparing the income of the corporation. Pick a US corporation booking its income in a state with a 12% corporate income tax then sure, saner corporations not so much.
And having consequences for your actions is a bad thing now?
You ignore half the equation. Germany has more external assets than the US. if I owe $5,000 on my credit card but have $6,000 in my checking account I'm in better shape than the guy who only owes $4,000 on his credit card but has $3,500 in his checking account.
Subtract external debts from external assets and Germany is at +$1.2 trillion (USD) while the USA is at -$2.4 trillion (USD). Note that Japan, whom Americans who like to pretend debt doesn't matter love to cite, is at +$3.4 trillion (USD).
Apropos "corduroy roads", corduroy fabric in Danish is Jernbanefløjl, which translated literally means - railway velvet! :)
I never thought of that! MightyMartian has a valid point that valuable, difficult-to-manufacture long chain hydrocarbons are being squandered to produce combustion.
That's the same way I feel about sequestering gold. This non-tarnish metal is an extremely valuable manufacturing commodity. And diamonds, the hardest substance known to man, are another stupidly sequestered resource.
Homo sapiens are dingbat dumb.
"1) And the US has a metric shit ton more resources than Germany."
Actually they are so backwards that they have no _metric_ shit at all.
TFA is a Bloomberg summary of a Nature commentary about a survey among permafrost scientists, and the main article isn't even linked by Nature. If this was just an excuse to fire up the global warming flame thread, go for it. However, the same issue of Nature has a far more important (for global change) paper that dismisses the CLAW hypothesis in which dimethyl sulfate released from marine organisms is hugely important for creating clouds. In looking for fluff, the meat got missed.
It is not like you can tell a country to make some changes so the ice stops to melt, this one is out of our control.... are we going to send more ice makers up north to continue freezing the water and ice caps so as they retain all their gases???
But won't thawed permafrost make it easier for more trees (and other plant life) to grow and sequester carbon? The Earth has tremendous balancing mechanisms. It's been WAAAY further out of balance before in its history and those very strong protection mechanisms kick in and push it back the other way. Obviously they DO have limits, but we're nowhere near pushing those. The scope of our pollution doesn't even begin to compare with some of the previous events on the Earth. Pre-human climate history is VERY interesting reading!
I propose we change the name to semi-permafrost.
1) It's also about the size of California. Excluding the mojave desert area, it's about the same population density.
2) German's strong Euro HURTS exports. WTF are you talking about? Just making shit up? It might be worth noting that the EU contributed more than 3x as much as the US during the recent involvement in Libya.
3) This is due in part to Germany's strict immigration policies. The US is also below "replacement rate" in fertility, but also leans on immigration to pick up the bulk of growth. Are you arguing for looser immigration policies in order to spur growth? Interesting...
4) Are you arguing that a European country is more business friendly than a US company? Germany provides national health care, as well as free University education. I like that model. Let's use it!
5) All Germans can go to University if they pass highschool, and even if they don't, they have a path to get there if they choose. Speaking of a class system (and I quote)
There is little available evidence that the United States has more relative mobility than other advanced nations. If anything, the data seem to
suggest the opposite. Using the relationship between parents’ and children’s incomes as an indicator of relative mobility, data show that a number of countries,
including Denmark, Norway, Finland, Canada, Sweden, Germany, and France have more relative mobility than does the United States.
6) Keep in mind the EU is one trading area. Do you live in Kentucky? If not, then importing Kentucky Bourbon is exactly as hard as importing Irish Whiskey or French wine or Polish Vodka for someone in Germany.
7) The Bush tax cuts won't be allowed to expire as long as Republicans control at least 33% of the government. They'll scream bloody murder if someone tries. Also, German's public debt is notably lower than the US, though I guess there are other areas that offset that?
8) Most ironically, the "Republican base", on average, are net recipients of the benefits of the programs they rail against, as you pointed out. Germans don't like that idea. Germans are the California or New York of the US.
9) Anything you can get in the US, you can also get in Germany. Name something where that isn't true.
10) Most German cars will kill their American counterparts on almost any track.
I guess you didn't see Suzuki's scare campaign come out today
And I guess, in your ardour to expose Suzuki's "scare campaign" you didn't read or comprehend the comment "Arctic temperatures are *not* rising ..." which you originally, and so impertinently, responded to. Eh?
