Mysterious Siberian Crater Found at "End of the World" May Portend Methane Climate Catastrophe

I am not a gas expert but such thing are common in places where mining takes place. You take stuff from the earth and eventually the thing collapse.
I think similar thing could happen with gas too, they pump gas from Yamal, right?
 
The article seems to indicate that the hole was caused by a methane explosion. They blamed it on global warming. While I believe in global warming I'm skeptical of attributing events like this to it.
 
Definitely seems like an explosion with the soil collected as such on the outside. Wouldn't happen like that with a sinkhole. I blame Obama.
 
It does look like explosion.
They pump gas from nearby field.
I think due to that pumping air got inside, and then some rock struck another rock and boom.
I doubt it is global warming related.
I blame Obama too. His Ukraine shenanigans are distracting russians from properly following gas extracting technology.

Isn't there methane in permafrost?

I think there is a little bit. But there is gas field nearby, so here are your usual suspects.

Why are you convinced global warming could not have caused this? The scientists clearly have no opinion yet, and I am certainly not informed enough to have a meaningful opinion, yet you seem to have already made up your mind. Do you know something the experts don't?
 
I thought that this was strange until I looked at the area on Google's satellite images, https://www.google.ca/maps/place/Ya...2!3m1!1s0x4490f67f6ee6a3df:0xabf0b626f13972d4 . Though the hole does not contain water, the bodies of water in the images look a lot like the hole, but with water. Maybe the water in one of these "lakes" dried up or leaked through underground channels.

It looks like this whole region was peppered with meteorites.

Skeptical doesn't mean that I have made up my mind. If they provide sufficient evidence I'd believe it.

look like but it is not.
these are very shallow lakes or rather pools of water in swamps.

Maybe I got it backwards. Maybe the holes open, and then water fills them.

Some of those bodies of water might only seem shallow. Yellowstone National Park reminds me of deceivingly deep bodies of water http://www.americansouthwest.net/wyoming/yellowstone/blue-pool_l.html .

'...(Reuters) - Methane from underground reservoirs is streaming from thawing permafrost and receding glaciers, contributing to the greenhouse gas load in the atmosphere, a study led by scientists at the University of Alaska Fairbanks has found.The study, published online on Sunday in the journal Nature Geoscience, is the first to document leakage of deep geologic methane from warming permafrost and receding glaciers, said its lead author, Katey Walter Anthony....'


it appears to be a documented global phenomena.

Melting permafrost also impacts the carbon cycle.

http://en.wikipedia.org/wiki/Permafrost_Carbon_Cycle#Environmental_impacts

'...Additionally, a sudden and steady release of carbon dioxide and methane from permafrost soils may lead to a positive feedback cycle where warming releases carbon dioxide into the atmosphere. This carbon dioxide, a greenhouse gas, causes atmospheric concentrations to increase, causing subsequent warming.[5] This scenario is thought to be a potential runaway climate change scenario...'
 
I am pretty sure that whatever methane is in the tundra will be released in the next couple centuries. Also a great deal of organic matter will be exposed to bacteria that depending on physical conditions will become CO2 or Methane.

What I am not convinced about is the methane hydrate in places like the East Siberian Sea Shelf. If that comes out our descendants will be in more trouble.

The 400 ppm CO2 that is current had a ~20-25 meter higher sea level and much warmer arctic last time it happened in the Pliocene. How much higher than 400 ppm we go is an open question.

http://en.wikipedia.org/wiki/Pliocene_climate

It was very recent in the geological sense, so many confounding factors other than CO2 level are not much at play for using the Pliocene as an analogue for our future.
 
Russian scientists had a short look at it.
hole is 30 meters in diameter and more than 50 meters deep.
They think it is basically a "fart" which happened last fall or this winter (ejected soil has vegetation)
Last year summer was warm, gases warmed up and pressure buildup resulted in permafrost layer being blown up.
There was another such crater, but not as fresh as this one.

The thing I don't understand is that it looks like it was giant bubble filled with gas before it burst.
I mean the is not much soil was ejected. Weird phenomena.
