Now I don't agree with this, as I do not believe in global warming- But I can see this stirring more arguments about global warming. Really it’s just a trap.

(March 4) -- Scientists have uncovered a powerful source of a leading greenhouse gas that is venting into the atmosphere at unprecedented rates. The permafrost beneath the East Siberian Arctic Shelf, a relatively shallow section of the Arctic Ocean, has been pumping 7.7 million tons of methane into the air each year -- roughly the amount released into the atmosphere by the rest of the world's oceans combined.
The researchers, who report their work in the March 5 issue of Science, caution that their findings in this previously unstudied region raise more questions than answers. The amount of methane released, though higher than expected, represents only a fraction of total global methane emissions.
But further warming could trigger added leakage of the greenhouse gas in the area, potentially leading to a positive feedback cycle. "The current global change might contribute to this process. It might accelerate this process," says University of Alaska Fairbanks scientist Natalia Shakhova. "The subsea permafrost is significantly more sensitive to further warming."
Methane ranks third on the list of greenhouse gas culprits, after water vapor and carbon dioxide, but its concentration in the air has more than doubled in recent centuries. In the past, atmospheric methane levels have varied between .3 and .7 parts per million. Currently, the numbers are up to 1.85 parts per million -- a 400,000-year high. Above the East Siberian Arctic Shelf, this figure is even greater.
"They're measuring very high concentrations that aren't observed elsewhere," says University of Florida climate scientist Ted Schuur, who has studied climate change in the region. "Carbon is moving between different parts of the earth system every year," he explains. "The question for the future is whether we are losing some kind of balance and going into a new carbon state."
The study by Shakhova et al. does not answer that question, Schuur says, but it highlights the East Siberian Arctic Shelf as a potentially critical hot spot for further research. Though that's a paradoxical description: It is a barren, frozen and thoroughly unpleasant region where "warm" temperatures are those just below freezing.
Shakhova and her colleagues braved the conditions, conducting eight separate research trips to the area over several years, ultimately taking more than 5,000 measurements at sea. Schuur and other scientists had studied the release of methane from the permafrost on land, but no group had analyzed the region below the water.
This underwater source has been subject to massive change. At various points in Earth's history, it has been a frozen plain that effectively traps its methane stores. But that plain was flooded as the world warmed since the last ice age, and it now sits under seawater significantly warmer than the air in the surrounding region. So while the terrestrial permafrost has remained frozen, its subsea counterpart has thawed, sending its methane stores into the atmosphere.
Shakhova explains that while the rate of release the scientists measured on the East Siberian Arctic Shelf is already high, relative to the rest of the world's oceans, it could still increase further. Several major rivers flow into that sea, and increased temperatures in the area could lead to more runoff.
This warmer river water could raise the temperature of the sea further, driving the release of still more methane. Shakhova estimates that even if just 1 percent of the methane stored in the permafrost were released into the air, it could triple atmospheric levels of the gas.
The broader implications of the findings are hard to gauge -- Shakhova said it is too early to tell how her research could affect the projections of the Intergovernmental Panel on Climate Change. But she and other scientists will be monitoring that icy hot spot for years to come.

Global warming is so last decade

Stopped reading.
oh man global warming is speading up
this is baaaaaad
[QUOTE=Sigfig;20570334]oh man global warming is speading up

And with only 1% release we will soon triple the atmospheric gas levels.... -> NATURAL PROCESS (secretly is darwin at work)
Look at all these earthquakes! They were caused by GLOBAL WARMING!!! OH GOD THINK OF THE CHILDREN!
God is ready to fart
Is anyone else sick and tired of hearing all this global warming bullshit? Get over it, it's natural, it happened before :v:
global warming is caused by democrat liberal socialist commies and obama care is a front for the new world order of fascism imposed by big government

you cannot be serious especially in this time of speading up in global environment
Oh for christs sake. The guy who brought up this bullshit about global warming needs to get a bullet through the head. I'm sick and tired of hearing this bullshit after we've proven that GW is NATURAL and happens every so often. Sure maybe greenhouse gases speed up the effect some but seriously its not enough to have a cataclysmic effect on Earth. Christ I hate people with no common sense. D:
Whether it's natural or not, it's still a threat to civillization. So stfu.
Anyone with any concern does need to remember that all news is biased and they want to fear monger the gullible into spending more money on so called "Green" products.
Lol climate change deniers :downs:

You are not a scientist.
You have zero understanding or authority to declare something that the overwhelming majority of climate scientists agree is human-caused to be "natural"

Cycles are natural.
We're speeding up the cycles, and intensifying them.
[QUOTE=EcksDee;20572743]Cycles are natural.

No we're not.
The cycles you're referring to are called Milankovich Cycles, and they take place over hundreds of thousands of years. They are due to orbital precession and the gradual shift of the earth's axial tilt. Carbon emissions aren't making the earth's axis move faster, and they're not changing the earth's orbit. So no, we're not speeding up or intensifying them.
Plus, we're already past the high point of the last Milankovich Cycle--if that was the only factor, we'd be getting colder, not warmer.
It better, it's been cold as shit here recently.
So is swamp gas legitimate?
Methane being released from old ice isn't exactly breaking news. I saw something about it on the discovery channel like ten years ago.

An overwhelming majority of scientists that have most likely been payed to say so, yes.
It's not like they actually researched it.

Then why is weather becoming increasingly varied?
[QUOTE=radioactive;20574195]Then why is weather becoming increasingly varied?[/QUOTE]
I meant that scientists have known about the pockets of methane trapped in the ice for at least a decade.
Sorry for not making that clear to begin with. But if you used a bit of logic, you would have realized that more ice melting in recent years = more methane released.
This is really old. We've known this for years.
[QUOTE=Taggart;20574013]An overwhelming majority of scientists that have most likely been payed to say so, yes.

So, the government paid off tens of thousands of climatologists to generate hundreds of thousands of fake research papers, then paid off all the scientific journals to accept and publish those fake research papers, then paid off everyone with a climatological background to pretend the papers weren't fraudulent, all so that the government could...tighten emissions regulations?
And this idea somehow doesn't seem fucking retarded to you?
guys you are so sheep you need to realise we are speading up the destruction of mankind to the date 2012 so that alien monsters can rain from the sly and claim all of our dairy products it's so obvious

Earth will always be fine up until the sun goes supernova and envelopes it in a few billion years. If this problem (climate change) isn't taken seriously, though, [B]CIVILIZATION[/B] is in big trouble.

Then you must not even be able to look in the mirror.
Cows fart and burp methane.
:q:
How can you not believe in global warming? Have you not felt the fucking heat?! :mad:
I mean, where do you honestly believe carbon emissions are going to, space?
You don't need to believe in it, you just gonna acknowledge it exists. Believing in global warming's like believing in the postman. (that analogy once again)
