There is no mystery. Arctic sea floor Canadian permafrost Siberian permafrost The Arctic sea floor is releasing Methane Clathrates, i.e. the so-called Methane Clathrates Gun is firing. As for the two instances of "permafrost", both are melting en mass and that is leading to organic matter that has been frozen and accumulating for millenia to now be decomposed by bacteria, leading to massive methane releases. Methane is 30-times for damaging than CO2.
