    Default Frozen Methane deposits in the Arctic beginning to melt

    The Arctic ocean is warming twice as fast as the rest of the oceans, and permafrost and the frozen methane deposits in the sea are melting.
    We aint got as much time as our politicians think, as people think, and as a species have been asleep at the wheel for long enough for it to become permanent.
    Quite apart from that, the ocean rotators are driven by warm/cold water, if the cold is not so……………..

    "Scientists have found evidence that frozen methane deposits in the ArcticOcean – known as the “sleeping giants of the carbon cycle” – have started to be released over a large area of the continental slope off the East Siberian coast, the Guardian can reveal.
    High levels of the potent greenhouse gas have been detected down to a depth of 350 metres in the Laptev Sea near Russia, prompting concern among researchers that a new climate feedback loop may have been triggered that could accelerate the pace of global heating.

    Should be some interesting religions popping up in the next century.

    Ah yes, blame something/someone else and ask for salvation………. very familiar story that.

    Part of the entitlement mindset in humans. They are entitled to an all powerful god to fix things when they've stuffed up. And boy, have we stuffed up!

    No asteroid needed for this extinction event.

    This has been going on for a while, already...about 3-4 years.

    Kind of makes Trump look like a little bump in the highway.

    Honestly, this truth makes me sad. The cold, hard honest truth is that vast numbers, if not the majority of human beings are incapable of looking forward more than about 5-6 years. Beyond that is never-never land.

    Methane hydrates or clathrates form when methane emitted by microorganisms in organic sediment is frozen under high pressure (i.e. deep in the ocean, 350-5000m) within the crystalline structure of water ice. Although the substance resembles water ice, when exposed to flame it will burn, and is also known as fiery ice.

    It really is sort of mind boggling to try to imagine just how many billions of tons of Carbon were sequestered by the biosphere between the rise of plant life and the arrival of fungi capable of digesting cellulose.

    Methane hydrates. Methane freezes ~295 below F, or ~180 below C
    And how much carbon is sequestered in marine contemporary sediments? Or in, say the white cliffs of Dover?

    not as much as the permafrost holds

    There are indications that most of the methane released from the seabed is consumed by methane-reducing bacteria in the water column, and very little of it actually reaches the surface.

    I met a good friend some weeks ago, who also happens to be International Director at the Norwegian Polar Institute. He told me that the glaciers on Svalbard have, on average, lost 3 meters of ice cover this year. That's a LOT of meltwater running into the ocean.

    The frozen methane is just getting started.

    I would think that such bacteria will be overwhelmed in short order.

    the bacteria are merely part of the cycle

    ergo, bacteria do fart

    Saturn’s moon Titan has lakes of methane.

    We can always move to Titan. It should be cooler there.
