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%.’

‘The parapet of these craters suggests an underground explosion.’ Pictures of Yamal crater taken by Vasily Bogoyavlensky

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.

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.


Exaustive Study Finds Atmospheric Concentrations Of Methane Gas Up To 75% Higher Than EPA Estimates

In Uncategorized on February 25, 2014 at 8:51 pm

America's natural gas system is leaky and in need of a fix, new study findsOldspeak: “Duh. When you understand that methane (b.k.a. “Natural’)  gas extraction; “fracking” creates “alarmingly high” uncontrolled gas emissions into the atmosphere. indefinitely. When you understand that methane gas leaks are persistent throughout the extraction, production and consumption cycle, this cannot be surprising. What is surprising to me is that anyone took the EPAs estimates seriously, when they for some reason, excluded natural methane sources, like wetlands and geologic seeps. With the largest sea floor methane seep in the fucking world  right off the coast of the Carolinas, and scientists have no idea how many more are out there, this makes no sense. And for some other ridiculously corrupt reason allowed methane gas extracting corporations to “self report” the emissions levels from their operations. That’s right. They don’t have to allow EPA access to their sites unless they feel like it. They just tell EPA whatever they like, and EPA has zero authority to trust but verify the numbers provided. And if Obama gets his wish to dramatically expand Methane gas extraction operations, ignoring the environmental destruction and contamination its extraction begets, we can expect this madness to get worse. Short explaination? We’re fucked.” -OSJ

By Mark Golden @ Stanford  News Service:

A review of more than 200 earlier studies confirms that U.S. emissions of methane are considerably higher than official estimates. Leaks from the nation’s natural gas system are an important part of the problem. This finding has important implications for natural gas as a possible replacement fuel for coal.

The first thorough comparison of evidence for natural gas system leaks confirms that organizations including the Environmental Protection Agency (EPA) have underestimated U.S. methane emissions generally, as well as those from the natural gas industry specifically.

Natural gas consists predominantly of methane. Even small leaks from the natural gas system are important because methane is a potent greenhouse gas – about 30 times more potent than carbon dioxide. A study, “Methane Leakage from North American Natural Gas Systems,” published in the Feb. 14 issue of the journal Science, synthesizes diverse findings from more than 200 studies ranging in scope from local gas processing plants to total emissions from the United States and Canada.

“People who go out and actually measure methane pretty consistently find more emissions than we expect,” said the lead author of the new analysis, Adam Brandt, an assistant professor of energy resources engineering at Stanford University. “Atmospheric tests covering the entire country indicate emissions around 50 percent more than EPA estimates,” said Brandt. “And that’s a moderate estimate.”

The standard approach to estimating total methane emissions is to multiply the amount of methane thought to be emitted by a particular kind of source, such as leaks at natural gas processing plants or belching cattle, by the number of that source type in a region or country. The products are then totaled to estimate all emissions. The EPA does not include natural methane sources, like wetlands and geologic seeps.

The national natural gas infrastructure has a combination of intentional leaks, often for safety purposes, and unintentional emissions, like faulty valves and cracks in pipelines. In the United States, the emission rates of particular gas industry components – from wells to burner tips – were established by the EPA in the 1990s.

Since then, many studies have tested gas industry components to determine whether the EPA’s emission rates are accurate, and a majority of these have found the EPA’s rates too low. The new analysis does not try to attribute percentages of the excess emissions to natural gas, oil, coal, agriculture, landfills, etc., because emission rates for most sources are so uncertain.

Several other studies have used airplanes and towers to measure actual methane in the air, so as to test total estimated emissions. The new analysis, which is authored by researchers from seven universities, several national laboratories and federal government bodies, and other organizations, found these atmospheric studies covering very large areas consistently indicate total U.S. methane emissions of about 25 to 75 percent higher than the EPA estimate.

Some of the difference is accounted for by the EPA’s focus on emissions caused by human activity. The EPA excludes natural methane sources like geologic seeps and wetlands, which atmospheric samples unavoidably include. The EPA likewise does not include some emissions caused by human activity, such as abandoned oil and gas wells, because the amounts of associated methane are unknown.

However, the analysis also finds that some recent studies showing very high methane emissions in regions with considerable natural gas infrastructure are not representative of the entire gas system. “If these studies were representative of even 25 percent of the natural gas industry, then that would account for almost all the excess methane noted in continental-scale studies,” said a co-author of the study, Eric Kort, an atmospheric science professor at the University of Michigan. “Observations have shown this to be unlikely.”

Natural gas as a replacement fuel

Even though the gas system is almost certainly leakier than previously thought, generating electricity by burning gas rather than coal still reduces the total greenhouse effect over 100 years, the new analysis shows. Not only does burning coal release an enormous amount of carbon dioxide, mining it releases methane.

Perhaps surprisingly though, the analysis finds that powering trucks and buses with natural gas instead of diesel fuel probably makes the globe warmer, because diesel engines are relatively clean. For natural gas to beat diesel, the gas industry would have to be less leaky than the EPA’s current estimate, which the new analysis also finds quite improbable.

“Fueling trucks and buses with natural gas may help local air quality and reduce oil imports, but it is not likely to reduce greenhouse gas emissions. Even running passenger cars on natural gas instead of gasoline is probably on the borderline in terms of climate,” Brandt said.

The natural gas industry, the analysis finds, must clean up its leaks to really deliver on its promise of less harm. Fortunately for gas companies, a few leaks in the gas system probably account for much of the problem and could be repaired. One earlier study examined about 75,000 components at processing plants. It found some 1,600 unintentional leaks, but just 50 faulty components were behind 60 percent of the leaked gas.

“Reducing easily avoidable methane leaks from the natural gas system is important for domestic energy security,” said Robert Harriss, a methane researcher at the Environmental Defense Fund and a co-author of the analysis. “As Americans, none of us should be content to stand idly by and let this important resource be wasted through fugitive emissions and unnecessary venting.”

One possible reason leaks in the gas industry have been underestimated is that emission rates for wells and processing plants were based on operators participating voluntarily. One EPA study asked 30 gas companies to cooperate, but only six allowed the EPA on site.

“It’s impossible to take direct measurements of emissions from sources without site access,” said Garvin Heath, a senior scientist with the National Renewable Energy Laboratory and a co-author of the new analysis. “But self-selection bias may be contributing to why inventories suggest emission levels that are systematically lower than what we sense in the atmosphere.”

The research was funded by the nonprofit organization Novim through a grant from the Cynthia and George Mitchell Foundation. “We asked Novim to examine 20 years of methane studies to explain the wide variation in existing estimates,” said Marilu Hastings, sustainability program director at the Cynthia and George Mitchell Foundation. “Hopefully this will help resolve the ongoing methane debate.”
