I can't believe that this got 350+ comments and nobody actually recognized the clickbait here. For one thing, it's a story from that noted climatology journal "The Siberian Times". https://en.wikipedia.org/wiki/Pingo https://en.wikipedia.org/wiki/Pingo They're full of ice, not methane. And what makes those craters is the ice melting and/or drop in groundwater pressure. The issue of entrained methane trapped in permafrost is real and the pingo ice most likely also contains trapped methane, but the implication that these are domes of pressurized methane READY TO BLOW AND HURL EARTH INTO RUNAWAY GREENHOUSE AT ANY MOMENT is absurd. The melting of permafrost generally over wide areas is the actual threat.
