Hundreds of giant 12,000 year-old craters caused by methane blow-outs found on the Arctic...

Researchers have discovered hundreds of huge craters, with many over 3,000 feet wide, on the seafloor of the Arctic Ocean.

The craters in the Barents Sea, north of Norway and Russia, formed through huge mounds full of methane exploding suddenly and catastrophically around 12,000 years ago, and are still leaking methane.

Scientists say the discovery could help explain why so many craters have appeared in Siberia over recent decades, with the same processes causing these explosive events.

...

he Arctic ocean floor hosts vast amounts of methane trapped as hydrates, which are ice-like, solid mixtures of gas and water.

These hydrates are stable under high pressure and cold temperatures.

The ice sheet provides perfect conditions for subglacial gas hydrate formation, in the past as well as today.

Some 2000 metres of ice loaded what now is ocean floor with heavy weight.

Under the ice, methane gas from deeper hydrocarbon reservoirs moved upward, but could not escape.

It was stored as gas hydrate in the sediment, constantly fed by gas from below, creating over-pressured conditions.

...

'As the ice sheet rapidly retreated, the hydrates concentrated in mounds, and eventually started to melt, expand and cause over-pressure.

'The principle is the same as in a pressure cooker: if you do not control the release of the pressure, it will continue to build up until there is a disaster in your kitchen.

'These mounds were over-pressured for thousands of years, and then the lid came off.

'They just collapsed releasing methane into the water column' says Andreassen.

Total BS. I bet these are some of the same A-holes telling us about climate change. I have about as much confidence in them as I do the MSM.

Somebody butter tell algore...the earth doesn’t have a fever, it’s just farting. Earth firing off SBDs...whodathunkit.

Or a lot of micro- and other organisms.

It Trump had not pulled us out of the Paris accord, those methane blow-outs would not have happened 12,000 years ago.

Time for the Paris crowd to plug the earth fart holes with euros.

There are large oceans of hydrocarbons on the moons of Jupiter and Saturn. It is all ‘natural.’

“When are we going to tax the Antarctic sea floor?”

Tax it? We need to fix it. There’s a lot of holes there.

I recently had a methane blowout and annoyed my wife.

Farts don't count!

Fascinating and logical.

Or it could just be Al Gore when he goes swimming.

There does seem to have been a whole lot of climate changing going on 12 -14 thousand years ago...

Yep - retreating ice shelves and all...we all died back then and will die all over again now that Trump has pulled out of the Paris deal....

12,000 years ago or 10,000 BC

Date of end of the Younger Dryas, the coldest period since the Ice Age. Cause believed to be comet fragment strike on the Ice Cap. Carolina Bays formed from ejecta. Heat of strike would have melted the methane ice on the bottom.

That was the largest climate change since the end of the Ice Age 1,000 years previous also caused by comet fragment strike. Both strikes believed to come from the break up of a very large comet or small planetoid remnants of which cause the twice yearly Taurids meteor showers

The largest climate change was several billion years previous when the Earth switched from methane base to oxygen base. Reason not known or clear. Began the Cambrian Explosion the (virtually) over night explosion of life on Earth of creatures fully formed ...

That's because, obviously, there were lots and lots of dinosaurs on those moons millions of years ago.

I think I just invented the "Abiotic Theory of Dinosaurs".
