If temps in those waters and at those depths go up enough so that this methane hydrate unfreezes and completely, then it will change the world beyond recognition.

Last time all that frozen stuff down there was in gas form in the atmosphere, planet Earth was an almost completely dead powerheater.

That is one of the big concerns here, we have been discussing how to either pump it all before it thaws or how to restore pre-human ecosystem in the arctic to keep it contained.

My concern is more the deep sea's methanhydrate before the arctic circle' methane. And not because of cataclysmic seismic wavesa and super Tsunamis wiping out Scandinavia and Europe like in Frank Schätzing famous novel, but because of an upheating of the atmosphere that even the Holy Greta will not know what to say anymore.

As I said, ther ewere era when all what now is frozen at the bottom of the sea was in the atmoshere. And the planet was extremly hostile to life then and was a planetary super-cooker.

Methane'S potential to warm the climate, over a 20 year period, exceeds that of CO2 by a factor around 85. Eighty-five.

Even if the methan dpown there wpuld be bound by the coean'S water, it would shift the ph level such that highe rlife anf iosh wpould not live anymore, and many algas and other lfie forms would go the way of the dodo, too. This then oinfluences the ocean's intersaction witht he aerial atmopshere and the poluttion there.

And you better build a strong love for jellyfish. It will be the only higher multi-cellular life-form in the ocean. You will not watch further than a few meters due to all the jellyfish.

Before it becomes too warm, that is. Then there will not even be jellyfish anymore. That is long after the coean'S oygene production and CO2 binding capability already will have dropped to zero. And with changes in the temperature gradients int he water, atmoppshere will chnage, mpisture in it. The land will be affected as well, so will be the hcmical mix of the air.

Breathing will become lets say "an issue".


But go on, everybody, get hystericla over your carbon footprint. Waste time and trillions for CO2 polcies while ignoring methane. The simple truth is, if the methane problem does not get solved, it simply will not make a difference at all what is being done regarding CO2. If you have a 10 cm rip in your heart'S wall, you do not care for a small cut in your fingertip, do you.



It is said that all that methane could be used for new forms of energy production. I am not in the knowledge to assess that.
