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.

‘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.’






The latest expedition to Yamal crater was initiated by the Russian Centre of Arctic Exploration in early November 2014. The researchers were first in the world who went down the crater of gas emission. Pictures: Vladimir Pushkarev/Russian Centre of Arctic Exploration

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.

2014 Was The Hottest Year On Record Globally By Far

Oldspeak: “It’s official. 2014 was hot as fuck. Like, Siberian permafrost melting hot. My question is, if it’s already record-shattering hot, what happens when El Nino, that usually accounts for abnormally hot periods arrives?!?!? I’m gonna the proverbial hell of all breaks loose. It’s my feeling that this is extinction event is happening far faster than even our most learned scientists realize. It is gaining speed in a non-linear fashion. Every single update and revision of the latest science and data speaks of underestimation. This is happening faster and far more unpredictably than even the most advanced climate models can predict. Given these facts, the likelihood of even more abrupt changes and effects, increases daily. Still, something close to silence on this, the only thing that is news, in corporate media. There has been more reporting on NYPD cops turning their backs on the mayor. We need a truth and reconciliation commission on the fate of our Great Mother.” -OSJ 

By Joe Romm @ Think Progress:

The Japan Meteorological Agency (JMA) has announced that 2014 was the hottest year in more than 120 years of record-keeping — by far. NOAA is expected to make a similar call in a couple of weeks and so is NASA.

As the JMA graph shows, there has been no “hiatus” or “pause” in warming. In fact, there has not even been a slowdown. Yes, in JMA’s ranking of hottest years, 1998 is in (a distant) second place — but 1998 was an outlier as the graph shows. In fact, 1998 was boosted above the trendline by an unusual super-El Niño. It is usually the combination of the underlying long-term warming trend and the regional El Niño warming pattern that leads to new global temperature records.

What makes setting the record for hottest year in 2014 doubly impressive is that it occurred despite the fact we’re still waiting for the start of El Niño. But this is what happens when a species keeps spewing record amounts of heat-trapping carbon pollution into the air, driving CO2 to levels in the air not seen for millions of years, when the planet was far hotter and sea levels tens of feet higher.

The JMA is a World Meteorological Organization (WMO) Regional Climate Center of excellence. The WMO had announced a month ago that 2014 was on track to be hottest year on record. Different climate-tracking groups around the world use different data sets, so they can show different results for 2014 depending on how warm December turns out to be.

But in mid-December, NOAA said it’s all but certain 2014 will be a record setter. It released this figure showing that

NOAA-YTD-11-14

all plausible scenarios for December still leave last year as the hottest ever (click to enlarge):

If you were wondering how 2014 could be the hottest year on record when it wasn’t particularly hot in the United States (if we ignore California and Alaska), NBC News has the story. It turns out there’s like a whole planet out there that has been getting very toasty:

Some of the hottest places in the world in 2014 included:

          • Europe was the hottest it’s been in 500 years. One new analysis concluded “global warming has made a temperature anomaly like the one observed in 2014 in Europe at least 80 times more likely.”
          • California had record-smashing heat, which helped create its “most severe drought in the last 1200 years.”
          • Australia broke heat records across the continent (for the second year running). Back in January, “temperatures soared higher than 120°F (49°C).”
          • Much of Siberia “defrosted in spring and early summer under temperatures more than 9°F (5°C) above its 1981 to 2010 average,” as Live Science noted. This is the second exceptionally hot summer in a row for the region, and scientists now think the huge crater discovered this year in the area “was probably caused by thawing permafrost.”
            • The permafrost (soon to be renamed the permamelt) contains twice as much carbon as the entire atmosphere. If we don’t reverse emissions trends sharply and soon, then the carbon released from it this century alone could boost global warming as much as 1.5F

 

 

 

Increasing Methane Releases From Thawing Arctic “Permafrost” Is Accelerating Global Warming, As Industrial Civilization Plunders On

In Uncategorized on April 9, 2014 at 1:08 am

Oldspeak: “ Arctic permafrost is an area of intense research focus because of its climate threat. The frozen ground holds enormous stores of methane because the ice traps methane rising from inside the Earth, as well as gas made by microbes living in the soil. Scientists worry that the warming Arctic could lead to rapidly melting permafrost, releasing all that stored methane and creating a global warming feedback loop as the methane in the atmosphere traps heat and melts even more permafrost….Researchers are trying to gauge this risk by accurately measuring stores of methane in permafrost on land and in the ocean, and predicting how fast it will thaw as the planet warms. Though methane gas quickly decays once it escapes into the atmosphere, lasting only about 10 years, it is 30 times more efficient than carbon dioxide at trapping heat (the greenhouse effect)….Shakova and colleague Igor Semiletov of the Russian Academy of Sciences first discovered methane bubbling up from the shallow seafloor a decade ago in Russia’s Laptev Sea. Methane is trapped there in ground frozen during past ice ages, when sea level was much lower.” -Becky Oskin

“When you consider that global atmospheric methane concentrations are higher than at any point in at least the last 650,ooo years and rising, you do the math. As fossil fuel use and temperatures  increase, the probability of a catastrophic methane pulse increase significantly.  it’s not good that scientists have no idea fast methane hydrates are melting, as the planet warms. That means 50 GiGATONS of methane gas could be released into the atmosphere at any timeThe arctic methane timebomb is ticking. it cannot be stopped or mitigated or adapted to. When it goes off it will be very very very bad for life on earth. We need to start accepting this reality.” -OSJ

By Mark Karlin @ Buzzflash:

In 1965, a singer-songwriter, Barry McGuire, wrote a song called “The Eve of Destruction.” It was inspired by the decade of violent foreign wars and civil rights clashes, but applies to the current acceleration of global warming:

But you tell me
Over and over and over again, my friend
Ah, you don’t believe
We’re on the eve
of destruction.

Don’t you understand what I’m tryin’ to say
Can’t you feel the fears I’m feelin’ today?

Some readers may find the recent BuzzFlash at Truthout commentaries on the devastating climate change that is occurring a bit gloomy and lugubrious.  After all, if US residents turn on the television or listen to the radio, few news outlets are discussing the looming cataclysm.  Also, like carbon monoxide, it is odorless. In the air around us, it is not visible.

More frequently, nonetheless, we are seeing reports of its volatile impact in hurricanes, droughts, deluges and the melting of glaciers and the Arctic ice, among other ominous signs of its growing destructive power.

Yet, still most people don’t believe “we are on the eve of destruction,” as fossil fuel plunderers are granted the rights – even subsidized by the US government – to continue their destruction of our ecosphere.

Climate change is not due to any single cause, although carbon dioxide is the key catalyst. However, global warming results from a chain reaction of toxic changes in the Earth’s eco-balance.

For instance, as temperatures rise, ice melts and reduces the cooling of the atmosphere, thus causing an even warmer environment.  As a result, areas that are covered with permafrost melt and methane is released.  With the release of methane, climate change exponentially increases.

The website TGD Daily reports:

A team of researchers lead by Florida State University have found new evidence that permafrost thawing is releasing large quantities of greenhouse gases into the atmosphere via plants, which could accelerate warming trends.

The research is featured in the newest edition of the Proceedings of the National Academy of Sciences.

“We’ve known for a while now that permafrost is thawing,” said Suzanne Hodgkins, the lead author on the paper and a doctoral student in chemical oceanography at Florida State. “But what we’ve found is that the associated changes in plant community composition in the polar regions could lead to way more carbon being released into the atmosphere as methane.”

Permafrost is soil that is frozen year round and is typically located in polar regions. As the world has gotten slightly warmer, that permafrost is thawing and decomposing, which is producing increased amounts of methane.

Relative to carbon dioxide, methane has a disproportionately large global warming potential. Methane is 33 times more effective at warming the Earth on a mass basis and a century time scale relative to carbon dioxide.

As TGD Daily notes, “If the permafrost melts entirely, there would be five times the amount of carbon in the atmosphere than there is now, said Jeff Chanton, the John Widmer Winchester Professor of Oceanography at Florida State.”

Methane is also increasingly being released from the oceans as ice that shielded it melts, with large methane bubbles, for instance, now rising up in the Arctic Ocean (which is expected to be free of ice cover in a few years due to higher temperatures) and being released into the atmosphere.

BuzzFlash at Truthout has mentioned before that the ruling elite in industry and in governments, in general, have moved from a position of virtually ignoring global warming and its likely devastation to a position of adaptation, if that is even remotely possible, to the pending disaster.

Given that sort of betrayal on the part of the developed world’s leadership, some of us may seek to live for the day, since we believe that there is little that we can do as we pass the last hours on the eve of destruction.

This is our collective Earth, however, and those who would so greedily lead us into an apocalyptic ruin should be removed from positions of power.  Attempts at halting the advancing deterioration of the planet cannot begin soon enough.
