Permafrost (frozen soil) left in the Arctic Ocean after the last Glacial Maximum is leaking to the surface at a pace that's worrying to some scientists. Some scientists are now saying that the permafrost layer which is thought to be 600-800 meters thick is actually thinner under the ocean where the temperature is warmer at ground level; thus the slow melting of the permafrost.



What is less known, is that there is a lot of greenhouse gas methane released from the seabed offshore the West Yamal Peninsula. Gas is released in an area of at least 7500 m2, with gas flares extending up to 25 meters in the water column. Anyhow, there is still a large amount of methane gas that is contained by an impermeable cap of permafrost. And this permafrost is thawing.
"The thawing of permafrost on the ocean floor is an ongoing process, likely to be exaggerated by the global warming of the world´s oceans." says PhD Alexey Portnov at Centre for Arctic Gas Hydrate, Climate and Environment (CAGE) at UiT, The Arctic University of Norway.

Thought I'd post this here for ATS to digest and discuss. So, what says ATS?

Great...now methane is going to become the enviromentalist boogey man.
They'll probably add a tax to Mexican food and try to make everyone strap a meter to their ass.

I wonder if this has anything to do with the villages that are falling asleep?

This was long thought to be a consequence of 'changing climate/global warming'. This pdf is from 2007. Sounds like it is happening faster than predicted.

To evaluate the effect of such changes on the volume of the seasonally thawing
organic material, we overlaid the permafrost projections on the digitized geographically
referenced contours of 59 846 wetlands in the Russian Arctic. Results for the mid-21st century
climate indicated up to 50% increase in the volume of organic substrate in the northernmost
locations along the Arctic coast and in East Siberia, where wetlands are sparse, and a relatively
small increase by 10%–15% in West Siberia, where wetlands occupy 50%–80% of the land. We
developed a soil carbon model and used it to estimate the changes in the methane fluxes due to
higher soil temperature and increased substrate availability. According to our results, by
mid-21st century the annual net flux of methane from Russian permafrost regions may increase
by 6–8 Mt, depending on climatic scenario. If other sinks and sources of methane remain
unchanged, this may increase the overall content of methane in the atmosphere by
approximately 100 Mt, or 0.04 ppm, and lead to 0.012 ◦C global temperature rise.

I think the sinkholes were an early sign. I wonder what the next sign will be.....?

IIRC the melting permafrost adds fresh water to the ocean current & jacks us up here in the States. (Canada too)

Chris Field, director of global ecology at the Carnegie Institution of Washington, says "that's the thing that is scary about this whole thing. There are lots of mechanisms that tend to be self-perpetuating and relatively few that tend to shut it off."

Sergei Kirpotin of Tomsk State University describes permafrost melting as an "ecological landslide that is probably irreversible". He says the entire western Siberian sub-Arctic region has begun to melt in the last three or four years.


Methane is a much more potent greenhouse gas than carbon dioxide, but it has a shorter life of about a decade. Ultimately it oxidizes to become carbon dioxide which then stays in the atmosphere for more than a hundred years.


Also this;

Arctic shallow seabed sediments have received little attention with regard to their contribution to the global carbon budget and, particularly, the marine CH4 budget, because of their small areal extent. However, recent work has highlighted the potential for significant CH4 release from Arctic sediments and suggests CH4 release from the Arctic is increasing over time, at least in some regions. The low temperatures that characterize Arctic sediments are not considered conducive to methanogenesis, but psychrophilic methanogens exist. In the case of the East Siberian Arctic Shelf (ESAS), shallow sediments have not been considered a CH4 source to the hydrosphere or atmosphere because submarine (offshore) permafrost, defined as sediments with a 2-year mean temperature below 0°C, acts as an impermeable lid, preventing CH4 escape.

Fig. 1. Dissolved CH4 in surface seawater (nM, upper) and the overlying atmosphere (ppm, lower) along the East Siberian shelf (from 10/2005). Matching areas of increased CH4 concentration noted by red circles.
However, recent data (2003-2005) from the ESAS showed extreme surface water CH4 supersaturation (up to 22,000% saturation), implying high sea-to-air fluxes. Elevated CH4 concentrations in the air above the sea surface along the ship route were detected in the SE Laptev Sea (Fig. 1). Moreover, extremely high dissolved CH4 concentrations (up to 20 µM) were detected in the surface layer of seawater beneath the sea ice during winter. Understanding the factors responsible for the observed high CH4 concentrations in the ESAS surface waters requires additional research.

With this all methane gas leaking out all over the place, what can YOU really do about it ? Nothing, mother nature is gearing up to rid herself of all the fleas. Mother Earth decided that she will gassssssssssssssssss all of you to sleeeppy land. Then earth can grow back the plantlife and be plentiful again. You cannot get away from mother nature or the mad mad space out there. SO, DEAL with it. gasssssssssssssss leak. The higher ups decided to deal with it by imaginating pollution control by a TAX. To scam more money out of you. he,he,he

Methane release has in the past almost extinguished all life on earth.
One such time was during the "permian triassic extintion event."
It is a very real threat,and if sea temperatures rise by 4degrees,we are screwed big time,as all the methane locked in hydrates on the sea floor will bubble to the surface and make the atmosphere toxic.

And there is nothing we can do to change it.

Maybe that's the reason for the mad rush to find habitable world's by TPTB. Maybe they know that time is running out.

Without a doubt this release of permafrost methane is the single greatest contributor to Earth/Solar driven climate change.

It is what we should be concerned about. It is real and at a magnitude not controllable in mankind's current state of thinking.

I remember reading about something like this years ago in Adbusters... it was called a positive feedback loop.
basically we've reached the point of no return, and as soon as the permafrost starts to melt, which was predicted like 6 years ago, methane is released, and well... the planet is just gunna keep getting warmer.

There's no point in arguing over whether it's man mad or natural, fact of the matter is it's happening and we need to find a solution to the problem, or find a way in which we can cope with it. The longer we turn a blind eye, and shrug it off as no big deal, the harder the impact it will have on us.

Sadly I don't think there is a solution.
The reason being that there is simply too much methane locked up in ice and on the sea floor for humans to be able to deal with it if it all goes gaseous.
The japanese(who are getting close) and others have being trying for many years to find a way of bringing methane hydrates into the energy market-but its very difficult,and very expensive.
One reason is that as they bring it from the sea floor it expands something like 1000times in size.
But even if they could flip a switch overnight and make a world where everyones houses/cars/trains/factories ran on methane-and even if it was free(in an attempt to save life on earth)there is still just too much of the stuff to make a dent in it.
It literally covers the entire area of all the continental shelves on the planet.
Never mind the amount locked in the ice caps.

The extinction event I mentioned earlier in the thread took place over a very small amount of time if my memory serves I think it was a matter of a few generations to reduce all life on earth by approx 85%.

There is a kind of "dead zone" in the fossil record in the time of the event(permian triassic) where there is hardly any evidence of life plant or animal-but guess what there is evidence of in that layer all over the world?

Methane.Lots and lots and lots of it.

What has happened before...

I hope so too.

But sadly it looks as though the reports of the growing amounts of methane released from the permafrost(over the last 5-10years) was a clue that methane hydrates on the sea floor would soon become unstable.
That is what we are seeing off the Siberian coast now,on the sea floor.

Not just the Siberian coast either-the east coast of the USA is also seeing increased release of methane:


Now a new study of the seafloor off the West Coast of the United States has revealed that these gaseous "leaks" are already escalating to a full blown jail break, with methane escaping at 500 times its average rate of natural release.

www.natureworldnews.com...


Temperature changes in the Gulf Stream are "rapidly destabilizing methane hydrate along a broad swathe of the North American margin," the experts said in a study published Wednesday in the peer-reviewed journal Nature.
Using seismic records and ocean models, the team estimated that 2.5 gigatonnes of frozen methane hydrate are being destabilized and could separate into methane gas and water.

usnews.nbcnews.com...

The amount being released at the moment is bad news for the environment,because it is much worse than co2 as a greenhouse gas-but if the ocean floors warm just a few more degrees,the amount will skyrocket eventually making the air we,and all life breathe,toxic.

While people may argue about if its our species fault or not,that is irrelevent-
its happening,doesn't really matter who turned on the gas when you are locked in an airtight room does it?
It won't help you get out of the room fighting about who is to blame.

I agree.
Its also I think,the reason for the "secret" deep underground bunkers that all the big powers have.
They read history and mythology,and use that knowledge to prepare for what they believe is a cyclic occurance.
They are correct-anyone can see our planet is one unstable little peach,and there are cycles we can observe.

We the Humans,are the creatures who have worked that out in a very short time.
I mean crocodiles-200 million years old or more-they didn't suss out how to build.
Dinosaurs lived for more than 400 million years and never worked out how to make fire.

We are the anomaly.
We are horrid but beautiful.
Intelligent but foolish.
We cannot comprehend reality but we will always try.
We made science and industry which has given us so much but will ultimatley take it away-unless we use the knowledge to take us off world.

Off world colonies-moon,mars,IO,Europa.
Animals,plants,humans and their eggs/DNA transported to other worlds.
Save all Earth life during the mega floods/quakes/meteors/tectonic shifts .
This should be the biggest funded project on the planet.

Maybe that is what the whole black budget/projects is about.
A lot of money has disappeared over the years-what if it went into an off world project?

Thats a lot of unmerited self-glorification for a species in extreme population overshoot and on the precipice of extinction via an impending self-made ecological collapse.

The crocs will still be here after the coming ecological implosion, but even if they are not... they were about 100x more successful as a species measured by the length of time it was able to survive, than the one that destroyed almost everyone and everything it touched, itself included, thats too dull to even recognize its own approaching, self-inflicted doom.

I just dont understand the unbridled naivety of so many and the delusional attributions they ascribe to humanity, explicitly or implicitly.

You paint humanity as the white knight that can ride in and save the day. Unfortunately, under all that white paint thats been shlocked on, is a deep, hollow void of blackness with a nature that is to consume and destroy nearly everything that it comes into contact with. And if by miracle a thing is not damned by its touch, it always ends up becoming corrupted and altered in a negative, destructive way.

Now, do you really want to "Save all Earth", or do you really just want to save yourself for a chance to perpetuate your, and by extension, humanitys, legacy? Because saving one dooms the other.

Earths best chance is an Earth with the cancer that has ravaged it excised. All the non-human animals best chance is a world devoid of the organism that mercilessly slaughters them without concern nor care, whether for pleasure or profit. All the plants; the oldest inhabitants of the land, best chance is a planet free of the malignancy that has grown exponentially out of control that presses into them on all sides, suffocating them, gnawing at them, and consuming and assimilating their natural mass into the unnatural structure of its ever expanding, ever consuming, ever taking, ever destroying, form.

Off world colonies?! You want the cancer to SPREAD?!? Ahh, right... you dont want to save the Earth... you want to save yourself....

May whatever God there may be, if it be just, never allow humanity to escape. May the deathly tomb it has constructed out of the former Eden, for both itself and innumerable other species, be its permanent and final resting place.

Fortunately the multitude of facts suggests that it seems highly probable, in fact a near certainty, that the above will indeed manifest, and that the most destructive, disharmonious species to ever taint this planet, will not survive to infect and destroy others.

To humanity... may it rot in well deserved oblivion.
