Oldspeak: “Since the area of geological disjunctives (fault zones, tectonically and seismically active areas) within the Siberian Arctic shelf composes not less than 1-2% of the total area and area of open taliks (area of melt through permafrost), acting as a pathway for methane escape within the Siberian Arctic shelf reaches up to 5-10% of the total area, we consider release of up to 50 Gt of predicted amount of hydrate storage as highly possible for abrupt release at any time. That may cause ∼12-times increase of modern atmospheric methane burden with consequent catastrophic greenhouse warming.Dr Natalie Shakhova of the University of Alaska Fairbanks, Dr Igor Semiletov from the Pacific Oceanological Institute at the Russian Academy of Sciences

“So, the arctic is melting, Rapidly. De-gassing massive not recorded in millions of years amounts of methane gas from areas previously thought of as “permafrost”.  And the process seems to be accelerating and expanding, making more likely the 50 megaton burp of methane referenced above catastrophically altering life as we know it on earth. But the news being reported in U.S. media is ISIS, Bibi Netanyahu’s controversial speech to the U.S. Congress, And an unarmed homeless man being shot dead by trigger happy cops. The methane time bomb is ticking away, and only a brave few are listening. Tick, tick, tick, tick, tick, tick, tick…. We now return you to your regularly scheduled programming.” -OSJ

By Anna Liesowska @ The Siberian Times:

Respected Moscow scientist Professor Vasily Bogoyavlensky has called for ‘urgent’ investigation of the new phenomenon amid safety fears.

Until now, only three large craters were known about in northern Russia with several scientific sources speculating last year that heating from above the surface due to unusually warm climatic conditions, and from below, due to geological fault lines, led to a huge release of gas hydrates, so causing the formation of these craters in Arctic regions.

Two of the newly-discovered large craters – also known as funnels to scientists – have turned into lakes, revealed Professor Bogoyavlensky, deputy director of the Moscow-based Oil and Gas Research Institute, part of the Russian Academy of Sciences.

Examination using satellite images has helped Russian experts understand that the craters are more widespread than was first realised, with one large hole surrounded by as many as 20 mini-craters, The Siberian Times can reveal.

Four arctic craters: B1 – famous Yamal hole in 30 kilometres from Bovanenkovo, B2 – recently detected crater in 10 kilometres to the south from Bovanenkovo, B3 – crater located in 90 kilometres from Antipayuta village, B4 – crater located near Nosok village, on the north of Krasnoyarsk region, near Taimyr Peninsula. Picture: Vasily Bogoyavlensky

‘We know now of seven craters in the Arctic area,’ he said. ‘Five are directly on the Yamal peninsula, one in Yamal Autonomous district, and one is on the north of the Krasnoyarsk region, near the Taimyr peninsula.

‘We have exact locations for only four of them. The other three were spotted by reindeer herders. But I am sure that there are more craters on Yamal, we just need to search for them.

‘I would compare this with mushrooms: when you find one mushroom, be sure there are few more around. I suppose there could be 20 to 30 craters more.’

He is anxious to investigate the craters further because of serious concerns for safety in these regions.

The study of satellite images showed that near the famous hole, located in 30 kilometres from Bovanenkovo are two potentially dangerous objects, where the gas emission can occur at any moment.

He warned: ‘These objects need to be studied, but it is rather dangerous for the researchers. We know that there can occur a series of gas emissions over an extended period of time, but we do not know exactly when they might happen.

‘For example, you all remember the magnificent shots of the Yamal crater in winter, made during the latest expedition in Novomber 2014. But do you know that Vladimir Pushkarev, director of the Russian Centre of Arctic Exploration, was the first man in the world who went down the crater of gas emission?

‘More than this, it was very risky, because no one could guarantee there would not be new emissions.’

Professor Bogoyavlensky told The Siberian Times: ‘One of the most interesting objects here is the crater that we mark as B2, located 10 kilometres to the south of Bovanenkovo. On the satellite image you can see that it is one big lake surrounded by more than 20 small craters filled with water.

‘Studying the satellite images we found out that initially there were no craters nor a lake. Some craters appeared, then more. Then, I suppose that the craters filled with water and turned to several lakes, then merged into one large lake, 50 by 100 metres in diameter.

‘This big lake is surrounded by the network of  more than 20 ‘baby’ craters now filled with water and I suppose that new ones could appear last summer or even now. We now counting them and making a catalogue. Some of them are very small, no more than 2 metres in diameter.’

‘We have not been at the spot yet,’ he said. ‘Probably some local reindeer herders were there, but so far no scientists.’

He explained: ‘After studying this object I am pretty sure that there was a series of gas emissions over an extended period of time. Sadly, we do not know, when exactly these emissions occur, i.e. mostly in summer, or in winter too. We see only the results of this emissions.’

The object B2 is now attracting special attention from the researchers as they seek to understand and explain the phenomenon. This is only 10km from Bovanenkovo, a major gas field, developed by Gazprom, in the Yamalo-Nenets Autonomous Okrug. Yet older satellite images do not show the existence of a lake, nor any craters, in this location.

Not only the new craters constantly forming on Yamal show that the process of gas emission is ongoing actively.

Professor Bogoyavlensky shows the picture of one of the Yamal lakes, taken by him from the helicopter and points on the whitish haze on its surface.

He commented: ‘This haze that you see on the surface shows that gas seeps that go from the bottom of the lake to the surface. We call this process ‘degassing’.

‘We do not know, if there was a crater previously and then turned to lake, or the lake formed during some other process. More important is that the gases from within are actively seeping through this lake.

‘Degassing was revealed on the territory of Yamal Autonomous District about 45 years ago, but now we think that it can give us some clues about the formation of the craters and gas emissions. Anyway, we must research this phenomenon urgently, to prevent possible disasters.’

Professor Bogoyavlensky stressed: ‘For now, we can speak only about the results of our work in the laboratory, using the images from space.

‘No one knows what is happening in these craters at the moment. We plan a new expedition. Also we want to put not less than four seismic stations in Yamal district, so they can fix small earthquakes, that occur when the crater appears.

‘In two cases locals told us that they felt earth tremors. The nearest seismic station was yet too far to register these tremors.

‘I think that at the moment we know enough about the crater B1. There were several expeditions, we took probes and made measurements. I believe that we need to visit the other craters, namely B2, B3 and B4, and then visit the rest three craters, when we will know their exact location. It will give us more information and will bring us closer to understanding the phenomenon.’

He urged: ‘It is important not to scare people, but to understand that it is a very serious problem and we must research this.’

In an article for Drilling and Oil magazine, Professor Bogoyavlensky said the parapet of these craters suggests an underground explosion.

‘The absence of charred rock and traces of  significant erosion due to possible water leaks speaks in favour of mighty eruption (pneumatic exhaust) of gas from a shallow underground reservoir, which left no traces on soil which contained a high percentage of ice,’ he wrote.

‘In other words, it was a gas-explosive mechanism that worked there. A concentration of 5-to-16% of methane is explosive. The most explosive concentration is 9.5%.’

Gas probably concentrated underground in a cavity ‘which formed due to the gradual melting of buried ice’. Then ‘gas was replacing ice and water’.

‘Years of experience has shown that gas emissions can cause serious damage to drilling rigs, oil and gas fields and offshore pipelines,’ he said. ‘Yamal craters are inherently similar to pockmarks.

‘We cannot rule out new gas emissions in the Arctic and in some cases they can ignite.’

This was possible in the case of the crater found at Antipayuta, on the Yamal peninsula.

‘The Antipayuta residents told how they saw some flash. Probably the gas ignited when appeared the crater B4, near Taimyr peninsula. This shows us, that such explosion could be rather dangerous and destructive.

‘We need to answer now the basic questions: what areas and under what conditions are the most dangerous? These questions are important for safe operation of the northern cities and infrastructure of oil and gas complexes.’

Pingos are mounds with an ice core found in Arctic and sub-Arctic regions.

They can reach up to 70 metres (230 ft) in height and up to 600 m (2,000 ft) in diameter. They usually appear when groundwaters penetrate between permafrost and the top layer, which melts in summer season. They usually form in drained lakes or river channels.

However, gas is not a factor in their creation.

Scientists Discover Hundreds Of Methane Leaks Bubbling From The Floor Of The Atlantic Ocean… Again.

underwater-bubblesOldspeak: “Fast on the heels of news of a gigantic chasm of a methane blow hole opening in the permafrost in Siberia, we see this.  Not sure why this is surprising any more. We’ve gone from zero gas seeps in these areas off the U.S. east coast to the largest seeps in the atlantic since the mid 2000s. Methane hydrates are being released from countless, unknown numbers of leaks all over the planet.  The most disturbing lines in this article for me are “about 40 of the leaks they detected came from depths of over 3,300 feet, likely originating from deeper reservoirs below the initial sediments that make up the sea floor. If that’s the case, those reservoirs could be a target for extraction by fossil fuel companies…” Translation: the bottom of the deep dark ocean is too hot too keep methane hydrates frozen, and energy corporations are licking their chops. As ocean warming increases, we’ll see more and more and more of these leaks discovered. Climate scientists view them with concern. Energy conglomerates view them as profit. Meanwhile, we have no idea which of these deep reservoirs of gas will become the catastrophic release; The methane time bomb that will release 50 or more gigatons of methane in to the atmosphere & collapse human civilization. Only time will tell. And there’s nothing we can do to defuse it. Tick, tick, tick, tick, tick, tick, tick….” –OSJ

By Jeff Spross @ Climate Progress:

In what could be a clue to the future effects of climate change, scientists have discovered a huge collection of methane leaks from the ocean floor off the United States’ eastern seaboard.

Their work, published Sunday in Nature Geoscience, used a research vessel equipped with sonar to map a 94,000-square-kilometer area that arcs from North Carolina up to Massachusetts. Within that expanse, according to Scientific American, they discovered around 570 separate plumes of bubbles rising from the floor of the Atlantic Ocean. And while the scientists haven’t yet collected samples, the bubbles’ sources suggest they contain methane.

The study is surprising, because such leaks are usually found atop known methane reservoirs — or above active tectonic regions — and scientists had previously thought very few such leaks were to be found in that area of the Atlantic shelf. “This is the first time anyone has systematically mapped an entire margin,” Christian Berndt, a marine geophysicist at GEOMAR in Kiel, Germany, who was not involved in the study, told Science Magazine. “They found that there was much more methane coming out than was suspected beforehand.”

Methane is a greenhouse gas, far more potent on a pound-for-pound basis than carbon dioxide. But at 90 metric tons per ear, the methane being released by the 570 leaks is dwarfed by the annual releases from human industrial and agricultural activity, as well as other natural sources. Still, the researchers estimate there could around 30,000 more of the leaks all over the world.

There’s also the possibility that climate change and alterations to ocean temperatures could lead to far bigger releases.

“These little bits of bubbling here or there will not make a memorable impact,” Jens Greinert, who heads the deep-sea monitoring unit at GEOMAR, told Science Magazine. “It becomes interesting only if you have a catastrophic release.”

Carolyn Ruppel of the United States Geological Survey, one of the study’s co-authors, told the New York Times that about 40 of the leaks they detected came from depths of over 3,300 feet, likely originating from deeper reservoirs below the initial sediments that make up the sea floor. If that’s the case, those reservoirs could be a target for extraction by fossil fuel companies, though more research will be needed to confirm. But most of the leaks came from 800 to 2,000 feet down, and pictures Ruppel and her colleagues were able to take with a submersible show that most of the methane is likely trapped in ice structures called hydrates in the initial sediments at the seabed.

That raises the possibility that the hydrates, which are extremely sensitive to changes in temperature, are being melted by warming waters. That heat could be brought by natural cycles and variability — or by climate change. Another twist is that most of the methane is absorbed by the ocean long before it breaches the surface. The process reacts with oxygen and releases carbon dioxide, which in turn increases the acidification of the ocean in the vicinity. So there’s the possibility that warming waters from climate change could release more methane, thus further speeding up the ocean acidification that is itself being driven largely by humanity’s carbon dioxide emissions.

But with the current evidence, what connection can be drawn to climate change — if any at all — remains unclear. The undersea pictures taken by the research team suggest at least some of the methane leaks have been active for hundreds of years or even a millennia.

“It highlights a really key area where we can test some of the more radical hypotheses about climate change,” John Kessler, a professor at the University of Rochester who was not involved in the research, told the New York Times. “How will those release rates accelerate as bottom temperature warms, or how will they decelerate if there are some cooling events?”

“We don’t really have all of the answers. But this is a great place to try to find them.”

“Hmm. Record low Arctic sea ice at a time it’s supposed to be at maximum. Coincidentally, that same day global average atmospheric concentrations of CO2 went above 400 parts per million, just as it had in around the same time the previous year. Meanwhile, what used to be meters wide plumes of methane gas have grown to a HUNDREDS OF KiLOMETERS in alarmingly short time. These non-linear feedbacks will accelerate as time passed and temperatures rise. As Elites Greenwasher Bill McKibben says, “it’s game over for the climate.” We’re hovering around 400 parts per million of CO2.  Oceans will continue to warm and acidify and melt more methane hydrates. it will be interesting to see what happens this summer. We’re likely to see a near ice-free Arctic.” -OSJ

By Robert Hunziker @ Dissident Voice:

Recent developments up North are cause for concern. The Arctic “sea ice area” registered a record low on March 9, 2014 at 12.88 million square kilometers. 1

Further confirmation, according to reports from NSIDC (National Snow & Ice Data Center, Boulder) and Cryosphere Today (Department of Atmospheric Sciences, University or Illinois), Arctic sea ice area dropped to a record low of 12.95 million square kilometers on March 10 of 2014. It is a measure smaller than that seen during the late 1970s and breaking the previous record low, set just three years ago, by 150,000 square kilometers. Sea ice extent, meanwhile, fell to 14.5 million square kilometers, a measure roughly tied with the previous record low set in 2011 and also below area values seen during the late 1970s.

Forebodingly, the abrupt ice loss may set the stage for new record lows of sea ice area, extent, and volume for the upcoming summer of 2014 (Arctic News.)

According to interpretation by Climate Change Institute (University of Maine), on March 10th, 2014, this “record low sea ice cover occurs at a time that typically features sea ice maximum.”

At the same time, the implicit danger of Arctic sea ice loss triggering subsequent methane release has been compounded by the recent occurrence (March 6th, 2014) of an earthquake, magnitude 4.5, at Gakkel Ridge, which fault line crosses over the Arctic, resulting in a massive spike up of methane in the atmosphere to 2,395 ppb. This was reported by Arctic News on March 6th: “The situation is dire, given that methane concentrations have risen strongly following an earthquake that hit the Gakkel Ridge.”

By its very nature, the wrath of Mother Nature is on full display (payback for fouling the air), as an earthquake shakes lose deadly methane, spiking to new highs, at the same moment in time when the Arctic ice cap shrinks to all-time seasonal lows, which, in turn, creates nail-biting nervousness about the upcoming, or following, summer ice seasons. Will all hell break lose, triggering massive methane release? Nobody really knows! But, the thought, the consideration must be existent.

And, regarding the infamous “2013 ice rebound” chatter in the USA, according to PIOMAS (Applied Physics Laboratory, University of Washington):  “It seems that last year’s rebound has been fully negated after a couple of relatively warm months (the flipside of the cold outbreaks in the US) and 2014 will start out at approximately the same level as previous years.” 2

“No matter how you slice it – by date, by year, by average, by anything – we’re still losing ice, 2013 was not a ‘recovery,’ and the Arctic Ice ‘death spiral’ swirls on… Again, I don’t want to jump to any conclusions about what will happen later this year, but this clearly puts lie to the claim that the Arctic is recovering. And I think we’ll have a lot more bad news like this ahead.” 3

The Methane Predicament

Excessive release of methane into the atmosphere is a threatening and a complex issue that impacts the entire planet, all-in negative. The risk is that a melting Arctic prompts massive release of methane. However, the scientific community is split on the outlook. Most scientists do not believe it an issue for the near future but do recognize the danger. On the other hand, there are some very prominent scientists who believe otherwise, that the Arctic region is a powder keg ready to explode at any time, any year.

For one, the Arctic Methane Emergency Group (AMEG), who answers their own query: “Why is Arctic Methane An Emergency?” by saying, “The reason, in one word, is: “Runaway.”

According to AMEG:

Arctic methane emissions are increasing as the Arctic warms several times faster than the rest of our planet. There are three huge reservoirs of Arctic methane till recently safely controlled by the Arctic freezing cold environment. They are now all releasing additional methane to the atmosphere as the Arctic rapidly warms (carbon feedback). The more the temperature increases and the longer the Arctic warms the more methane these sources will emit. That much is certain.

Furthermore, AMEG claims:

If methane release from Arctic sea floor hydrates happens on a large scale… then this situation can start an uncontrollable sequence of events that would make world agriculture and civilization unsustainable. It is a responsible alarm, not alarmist, to say that it is a real threat to the survival of humanity and most life on Earth.

Down Under, Carlos Duarte, PhD, Director, Oceans Institute, University of Western Australia, who was awarded the Prix d’Excellence by the International Council for the Exploration of the Sea, claims that the “future of human kind face dire consequences due to arguably the first signs of dangerous climate change in the Arctic…”  4

In that regard, the National Academies have stated that the Arctic has already started an “abrupt climate change,” 5  causing one to wonder (shudder) if their analysis qualifies within Duarte’s “dire consequences” statement.

The Global Warming News Syndrome

Over the past several months, the mainstream (and other heterodox) news services have been filled with joy and celebration all across the land over the ostensible bounce back in Arctic sea ice, thus, knocking the props out from under the climate change (warming) advocates, who consistently scare the daylights out of the public with doomsday forecasts of Arctic sea ice loss prompting uncontrollable methane release, leading to a series of problems like food shortages, violent weather systems (already present), and runaway global warming, all because of the reckless use of fossil fuels.

Regrettably, as for the health of the planet, the same USA news sources that aggressively reported the death of global warming were, themselves, dead wrong.

As usual, climate change is not capricious outside of its trend. It shows its true colors over time, and the unfortunate fact of the matter is a trend is a trend until broken. The trend for Arctic ice is decidedly down, melting away by the decade, losing its substance in the face of a leviathan of methane.

Those journalists who pounded the table the hardest about the demise of global warming should spend more time thoroughly analyzing the repercussions of an ice-free Arctic, as well as finding a solution to getting off fossil fuels.

There’s an assignment.
