The one thing we can predict with certainty about Global Warming is, we are in for many surprises as our climate convulses from it's relative stability of the recent past, to who knows what lies ahead in the future.
Yet another explosive hole has been found in Siberia. The 3rd crater was found hundreds of miles to the east of the first 2 craters. It seems this crater has a similar structure to the others.
As scientists continue to study this phenomenon, some are leaning toward a theory.
Large spikes of methane being released into the atmosphere above Siberia may be tied to the mysterious craters which have appeared in the landscape, according to a US scientist.
The geologist's blog links the craters to climate change, as the melting Siberian permafrost is allowing the greenhouse gas to escape and create the enormous holes.
There is not a consensus yet as to what is really happening in Siberia, but new data are being collected and the dots are starting to connect.
Using data from a ground-based climate observing station in Tiksi, a small town in the Sakha Republic on the Arctic Ocean coast, Dr Box discovered "high end" levels of methane. The readings were backed up by data from similar stations in Alaska and Canada, according to News.com.au.It appears that witnessing the formation of these craters can be rather frightening.
The spikes, which Dr Box calls "dragon breaths", may well be connected to the unusual holes that have appeared in the Siberia landscape over the last month.
'Observers give several versions. According to the first, initially at the place was smoking, and then there was a bright flash.
And you better watch your step when you're wondering around out there.
The third crater and hole is in the Taymyr Peninsula and was accidentally discovered by reindeer herders who almost fell into it, in the vicinity of the remote outpost of Nosok.So we now have 3 craters in Siberia.
The funnel is a perfectly formed cone, say locals who are mystified over its formation.
Its depth is estimated at between 200 to 330ft (60 to 100 metres) and its diameter - more than 13ft (four metres).
A single event of this kind might be easy to overlook as an aberration. A freak case that might well be attributed to unique conditions. But over the past two weeks not one, not two, but three large holes, all retaining the same features, have appeared within the same region of Yamal, Russia.Dr. Box goes on to speculate that the release of methane from the ground and the oceans can change the effects of Global Warming very quickly.
A single event may well be easily marked off as a strange occurrence, but three look more like the start of a trend.
"If we don't get atmospheric carbon down and cool the Arctic, the climate physics and recent observations tell me we will probably trigger the release of these vast carbon stores, dooming our kids to a hothouse Earth," Dr Box wrote.As the denialists continue to spew their pseudoscience nonsense, and as the fossil fuel industry puppets in congress continue to block anything that might secure a stable climate for our children's future, the dragons in the earth are beginning to roar.
Similarly to Siberia's craters, bubbles of methane have been recorded rising to the surface of the Arctic Ocean since 2011.
"Atmospheric methane release is a much bigger problem than atmospheric carbon dioxide release, since methane is around 20 times more powerful greenhouse gas," he added.
UPDATE: An article was just published a few hours ago in Scientific American about this.
Still nowhere near a definitive answer, but some interesting speculation.
The crater's formation probably began in a similar way to that of a sinkhole, where water (in this case, melted ice or permafrost) collects in an underground cavity, Romanovsky said. But instead of the roof of the cavity collapsing, something different occurred. Pressure built up, possibly from natural gas (methane), eventually spewing out a slurry of dirt as the ground sunk away. Anna Kurchatova, a scientist at the Sub-Arctic Scientific Research Center in Russia, made a similar observation to The Siberian Times.There are still a lot of scientists who are betting Pingo. I just like saying Pingo because it's such a cool term, so I'm going to use it as much as possible. :)
