Our present extreme fossil fuel driven carbon dioxide global warming is predicted to produce exactly the same methane release from the subsea Arctic methane hydrates and deep mantle methane from the Enrico Pv Anomaly Extreme Methane Emission Zone by the 2050's, leading to total deglaciation and the extinction of all life on Earth.
It's impressive alright. Can anyone analyse it for us mortals? It certainly sounds (in certain parts) less than scientific but I'm no judge.
What mankind has done in his infinite stupidity with his extreme hydrocarbon addiction and fossil fuel induced global warming has opened a giant, long standing (Permian to Recent) geopressured mantle-methane pressure-release safety valve (Enrico Pv Anomaly Extreme Methane Emission Zone) for gases generated between 100 km and 300 km depth and temperatures above 1200°C in the Asthenosphere. There is now no fast way to reseal this system because it will require extremely quick cooling of the Arctic Ocean, which cannot be achieved in the short time frame we have left to complete the job. Our only hope is to destroy the methane in the water before it gets into the atmosphere and simultaneously destroy the existing atmospheric methane using radio-laser systems

I've not heard of any genuine climate scientists talking about methane hitting life-on-earth threatening concentrations. Methane in the atmosphere has a relatively short half life ( 7 years? ) so it would need to be released in the atmosphere at exceeding high rates for it to build up to the levels discussed, and even then it would only stay at those levels for as long as the release continued, plus a few years.
CO2 has a half life of centuries. CO2 emissions a cumulative over many generations.
Even if methane started to be released at a rate that triggered positive feedback (eg. from melting permafrost) the rate of release would not accelerate fast enough to overwhelm the natural decay of the released methane in the atmosphere to the point predicted.
Total deglaciation is somewhere between possible and probable. Total extinction of life on Earth is almost impossible. 95% of it maybe, but eradicating the hangers-on is no so easy.

A bit like those food preparation room spammers?
