I personally think we have already entered the nonlinear phase of global warming, where this particular positive feedback cycle of subsea methane being released, has started. Whether that leads to mass extinction events, is up to us. I read about a trillion would curb global warming, so how is it we cannot get that done, given that we have handed tens of trillions to the banks? It's a matter of wanting to do it and taking back the power that belongs with the people.
Thanks for the link, am gonna dive into it now.

""I am concerned about this process, I am really concerned. But no-one can tell the timescale of catastrophic releases. There is a probability of future massive releases might occur within the decadal scale, but to be more accurate about how high that probability is, we just don't know," Dr Shakova said.
"Methane released from the Arctic shelf deposits contributes to global increase and the best evidence for that is the higher concentration of atmospheric methane above the Arctic Ocean," she said.
"The concentration of atmospheric methane increased unto three times in the past two centuries from 0.7 parts per million to 1.7ppm, and in the Arctic to 1.9ppm. That's a huge increase, between two and three times, and this has never happened in the history of the planet," she added."
