Siberian Permafrost Methane Shows Growing Eruption: Number of Global Warming-Induced Craters Now Estimated at 20-30

Siberian Crater Locations

The ground smoked for hours. Then, with a great flash and an enormous boom, the land exploded. When the smoke cleared, all that was left was a great, black hole. Ejected earth lay scattered around it — sheer sides plunging into the permafrost like some gigantic, gaping gun barrel.

This was the scene last summer in Yamal, Siberia — a region of extreme northern Russia.

Mysterious Holes Emitting Methane Gas

Speculation about the cause of this mysterious hole became rampant. It looked like a sink hole, except for the ejected material surrounding it. Some said it was a pingo. But pingos weren’t known to form due to explosions.

Teams of scientists rapidly descended upon the hole. And there they found high readings of methane at the hole’s base — in the range of 10% concentration, which is a very explosive level for the gas. At the base of the hole they also found evidence of hydrate. A form of frozen water-methane that is quite unstable unless kept under high pressure and low temperature.

The initial conclusion of the Russian scientists was that relic hydrate sealed beneath the previously flooded Siberian permafrost had been destabilized. Eventually reaching an explosive concentration, it then erupted from the ground.

Discovery of this methane crater spurred a sweep of the area. Almost immediately, two other craters with similar features were discovered. And throughout fall and winter, both ground searches and satellite reconnaissance identified still more.

Now, according to recent reports in the Siberian Times, a total of seven craters with features similar to the Yamal eruption have been pinpointed by observers. Just one of these craters (shown above) hosted about 20 smaller ‘baby craters’ surrounding it. In this instance, a large methane store below the permafrost is thought to have explosively displaced a shot-gun pattern of frozen soil sections before filling with water.

Most of the craters, like the one above, were observed to rapidly fill with water even as they continued to emit methane. In many instances, the methane emission was visible as bubbles on the newly formed lake surface.

Bubbles from Methane Crater Lake

Additional reports from reindeer herders have led these same scientists to believe that in the range of 20-30 of these methane eruption holes are likely to exist in this region of Northwestern Siberia.

A Problem of Relic Hydrates Facing Rapid Warming

The fact that reindeer herders keep discovering new holes and that the first Yamal craters discovered earlier this year were recent events have led local scientists to believe that the eruptions are a new phenomena for Siberia. There, temperatures have warmed by a stunning 2 degrees Celsius within the mere span of 14 years. A very rapid rate of warming that is putting severe stress on the geophysical stability of this Arctic region.

Last night, as polar amplification again ramped up, we saw an example of this very rapid warming with locations in Yamal, Russia experiencing -3.1 C temperatures as of 1 AM Eastern Standard Time. A very warm measure for this region during winter time — representing an anomaly at least 20 degrees Celsius above average. For reference, North Texas, an area far south of the Arctic Circle, experienced similar readings (-3.4 C) at the same time:

In other words, it was colder in North Texas last night than it was in Yamal, Siberia near the 70 degree North Latitude line beside the Arctic Ocean.

This extremely rapid warming is thought by Russian scientists to have destabilized zones of relic hydrate trapped beneath the permafrost. There, the methane gas bonded with water to form a kind of methane ice.

Sandwiched beneath frozen permafrost, the hydrate remains stable so long as temperatures and pressures are relatively constant. Any increase in warmth — either through geological processes working below the hydrate, or from changes at the surface causing permafrost to melt and warmer, liquid water to contact the hydrate — would result in increased hydrate instability.

Yamal Crater Wall

In some cases, the gas would very rapidly liberate from its frozen traps forming increasingly high pressure pockets beneath the permafrost. If these pockets reach 10 percent methane concentration, they become very explosive and can be ignited when in contact with a catalyst or ignition source. The result, either due to very high pressure or ignition, is plugs of permafrost exploding from the ground as the gas erupts to the surface.

Conditions in Context

It is important to note that the amount of methane liberated by these initial eruption events is likely rather small — when considered on the global scale. However, what we see in Siberia now may be part of a growing and ominous trend.

First, we do not know the size of the potential methane store that could be liberated in such an explosive fashion. And the question must be asked — if we are looking at such rapid warming of methane hydrates in shallow sea and former shallow sea regions, what scale eruptions could we potentially experience in the future? Could very large sections of hydrate go critical? Areas possibly covering hundreds or thousands of square meters or more?

The Russian scientists seem very concerned. And, ironically, it is for the future safety of their oil and gas infrastructure, which sits atop what is potentially a rapidly destabilizing zone. A zone that could see explosive eruptions of the ground beneath pipes, equipment and extraction fields. (One would think that the Russians would also begin questioning the continued exploration and production of oil and gas considering its contribution to the dangers they are now identifying. But that level of wisdom appears absent in the recent assessments.)

Second, it appears that these methane eruptions provide pathways for ongoing release. Not all of the gas in the relic hydrate is initially liberated. And the structures that remain apparently release methane gas for some time — as is evidenced by continued high methane concentrations found at crater sites and by observed emissions from crater lake surfaces.

In essence, if this is a growing trend, then it is a rather unsettling one. Especially when one considers that it is just a single instance of many possible amplifying carbon feedbacks set off by a very rapid human warming. Particularly, the explosive land and ocean floor-altering nature of this specific carbon feedback makes it especially troubling. For it encompasses the very nature of a catastrophic upheaval.

In the end, the question must be asked — is Siberia sitting atop a methane volcano that is being prodded to rapid wakening by high-velocity human warming?

The Keystone Pipeline, Arctic Methane Eruptions, and Why Human Fossil Fuel Burning Must Swiftly Halt

Human fossil fuel emissions heating the Earth’s airs, waters, and ice.

From historic droughts around the world and in places like California, Syria, Brazil and Iran to inexorably increasing glacial melt; from an expanding blight of fish killing and water poisoning algae blooms in lakes, rivers and oceans to a growing rash of global record rainfall events; and from record Arctic sea ice volume losses approaching 80 percent at the end of the summer of 2012 to a rapidly thawing permafrost zone explosively emitting an ever-increasing amount of methane and CO2, it’s already a disastrous train-wreck.

Since the 1880s, humans have emitted nearly 600 billion tons of carbon into the atmosphere. This vast emission has spiked atmospheric CO2 and CO2e (when all other heat trapping gasses are included) levels to above 400 parts per million and 481 parts per million respectively. According to climate sensitivity and paleoclimate science, these volumes are already enough to increase global temperatures by between 1.5 to 2 C this century and 3-4 C long term.

At the current carbon emissions rate of more than 10 billion tons each year and growing at around 2 percent, humans will have emitted a trillion tons of carbon by 2041. Under business as usual fossil fuel burning, more than 2.5 trillion tons of greenhouse gas trapping carbon will hit the atmosphere before the end of this century. It’s a terrible blow we will sorely want to avoid. And one we can only circumvent if we start working to radically curtail carbon emissions now.

Already, we can see instances of emissions-driven climate change and related harm. But what we see now is minor compared to what the future holds in store. We’ve warmed the Earth by more than 0.8 degrees Celsius since the 1880s, and if human emissions do not swiftly come to a halt, we could easily see warming of 4, 5, 7 C or more by the end of this century alone.

Probability of stabilizing below 2 C

(Probability of exceeding 2 C warming this Century [equilibrium climate sensitivity] given a certain level of human greenhouse gas forcing. Note that this study did not include feedbacks from Arctic carbon stores. Also note that current CO2 equivalent forcing without aerosols is around 481 CO2e and with the aerosol negative feedback is around 425 CO2e. Also note that equilibrium climate sensitivity is about half that implied by Earth Systems Sensitivity over the long term [many centuries]. For a final note, consider that the aerosol negative feedback is temporary. Image source: IPCC.)

What Does Warming Look Like If We Continue To Burn Fossil Fuels?

We talk about warming in terms of degrees Celsius and gigatons of carbon burned. But what does it all really mean?

Droughts rampaging through the lower to mid latitudes as the US, Southern Europe, India, the Middle East, Brazil, Australia, the Sahel and sections of China rapidly turn to desert. Stratified oceans turning into extinction engines for fish and marine life, fresh water poisoning due to toxic algae blooms, oceans emitting increasing volumes of poisonous hydrogen sulfide gas into the air. Fires the likes of which we have never seen in the far north as the permafrost burns and methane leaks and explodes from the thawing earth. Floods raging from an atmosphere whose moisture cycling has increased by 30 percent or more. Sea level rise rapid enough to swallow cities and coastlines over the course of decades. Devastating storms emerging from the regions closest to large glacial melt events bordering Greenland and West Antarctica. And all around, more and more people migrating, trying to find a place that is not being gobbled up by desert, incessantly burning, ravaged by storms, flooded, or poisoned by toxic air and water.

Very Large Algae Bloom Barents

(Very large bloom of micro-organisms north of Scandinavia in Arctic waters on August 14, 2014. Arctic waters are rich in nutrients. As they warm and as the sea ice retreats, larger areas are freed for invasion by major blooms of algae and other microbes. Large enough blooms can rob the ocean of oxygen, produce harmful toxins, result in large fish kills, and in the end create dangerous bottom conditions favoring microbial hydrogen sulfide production. Image source: LANCE-MODIS.)

That’s the dark future we inch closer to with every 0.1 C degree of further warming, with each additional megaton of fossil fuel and industrial carbon hitting the atmosphere.

And it is in this context that we must judge our actions and those of our leaders in reducing or in failing to reduce a nightmare that now grows in intensity with each passing year. A nightmare we create and continue to contribute to each time we light a fossil fuel driven fire.

Quibbling over Keystone Carbon Emissions When Tar Sands is the Real Issue

50 billion tons. That’s the amount of extractable, burnable carbon that likely sits beneath what were once the green forests of Alberta and are now little more than a sprawling waste of smoking pits covering tens of square miles. It’s more than 8 percent of the carbon we’ve already dumped into the atmosphere and it’s a volume of carbon we simply cannot afford to burn.

1.7 million barrels of crude oil per day now comes out of a place that Tolkien would likely describe as a mechanized orc warren. Keystone would boost that total to 2.2 million barrels per day, enrich the pit owners, and lay the groundwork for an ever-more-rapid exploitation of this dangerous pile of atmospheric heat-venom.

This week, a recent study out of Stockholm’s Environment Institute found that the pipeline itself would result in at least 4 times the carbon emissions currently estimated by the US State Department. This, well-duh, assessment, came as pit mining cheerleaders such as the American Petroleum Institute and Canadian Industry groups marshaled yet another effort to ram the pipeline through and boost global carbon emissions all in one go.

In the end, all fossil fuels are terrible, adding to the global nightmare described above. But tar sands are between 12 and 20 percent more carbon intensive than even regular oil, especially when burning of the, worse than coal, coke bi-product is taken into account.

Arctic Methane Explosions — A Result of Human Warming

On the other side of the Arctic from the smoking fossil fuel pits of Alberta, nature is in the process of excavating a new, and no less terrifying, kind of pit. For from the Siberian tundra this summer were discovered three gaping wounds in the earth. Black holes shaped by impressive charges of methane blasting up from beneath the thawing permafrost.

All around the holes were ejected material. A kind of reverse meteor strike or methane volcano in which frozen methane trapped in clathrate beneath the thawing permafrost warmed enough to destabilize. The thawed methane built up in pressure pockets 250 feet or more below ground. Eventually, the pressure became too great and the permafrost overburden erupted, ejecting both earth and methane into the air above.

Eyewitnesses described eruption scenes where the Earth at first began to smoke. The smoke continued to bleed from the ground. Then, there was a loud flash and bang. When the smoke cleared, the methane eruption craters were plainly visible — a rim of sloped and ejected earth surrounding a black, gun-barrel like structure tunneling deep into the ground.

Scientists investigating the sites of these explosions found methane readings of 9.8% at the bottoms of the holes. These are high enough levels to burn if exposed to an ignition source — an atmospheric reading 50,000 times the current and already highly elevated ‘normal’ level.

Russia Siberia Crater

The Arctic permafrost alone contains about 1.5 trillion tons of carbon. And when it thaws, a portion of that carbon is bound to be released. It will be broken down by microbes and turned into methane in wet soil. In drier soil, it will form a peat like underburden that will slowly release CO2 by decay or, in more violent instances, by burning in one of the ever more powerful wildfires raging through the Arctic during the increasingly hot summers.

Beneath the icy permafrost layer are pockets of frozen methane in the form of clathrates. These structures are not included in the 1.5 trillion ton carbon estimate for permafrost. They are an addition of likely billions more tons of carbon. And, this year, we can now see a physical mechanism for their continued release — warming and thaw of the permafrost overburden.

The Human-Arctic Feedback Link: Why We Absolutely Must Stop Burning Fossil Fuels, And Swiftly

It is estimated that 1.5-2 degrees Celsius worth of global warming (5-8 C Arctic warming) is enough to thaw all the permafrost and eventually release a substantial portion of the carbon stored in and beneath it. For the Arctic warms much faster than the globe as a whole. In tundra regions, rates of warming over the past three decades have been 0.5 degrees Celsius per decade or more. In the region where the methane craters were discovered, recent temperatures at 5 degrees Celsius above average, during summer heatwaves in 2013 and 2014, have been reported.

As a result of past and current human greenhouse gas emissions, we have already locked in a substantial and significant rate of Arctic carbon emission feedback. And the speed of the Arctic carbon store release will likely determine how rapidly and whether other global carbon stores also respond.

A 2011 survey of 41 Arctic researchers found that rapidly reducing human greenhouse emissions would limit the volume of carbon feedback from the Arctic to 10% of the annual current human emission (or about 1 billion tons of carbon per year) by the end of the 21rst Century, but continue that emission for centuries to come (current Arctic carbon emissions are likely in the range of 30 million tons of methane and 100 million tons of CO2 each year). This is bad news. For we have already burned enough fossil fuel to keep warming on the trajectory to hit 1.5 to 2.5 C this century and 3-5 C or somewhat more long term — a bad result, and one that would likely require extensive human deployment of atmospheric carbon capture technologies. But it is far better than the alternative.

For continued fossil fuel burning would be enough to force a release of Arctic carbon stores equal to 35% or more of the human annual emission, or about 3.5 to 4 gigatons of carbon each year. By itself, this emission would easily represent a mini-runaway pushing the business as usual burning level of 800 ppm CO2 and 1,000 ppm CO2e by end century to 1,400 ppm CO2 + over the course of centuries and likely resulting in 4-7 C + warming this century and 12-14 C + worth of warming long term. A hothouse extinction event to rival or potentially exceed the worst seen in the geological record.

We simply must stop fossil fuel burning as it risks triggering ever greater carbon releases from stores around the globe and especially in the Arctic. In this way, stopping fossil fuel burning or failing to stop that burning is directly related to the ferocity and intensity of the Earth systems response we set off. And halting the Keystone Pipeline is a good approach to curtailing future carbon emission increases. A good start to a long, hard road ahead.
