https://en.m.wikipedia.org/wiki/Clathrate_gun_hypothesis https://en.m.wikipedia.org/wiki/Clathrate_gun_hypothesis The clathrate gun hypothesis is the popular name given to the idea that increases in sea temperatures or drops in sea levels can trigger a strong positive feedback effect on climate: first, warming causes a sudden release of methane from methane clathrate compounds buried in seabeds and seabed permafrost; second, because methane itself is a powerful greenhouse gas, temperatures rise further, and the cycle repeats. This runaway process, once started, could be as irreversible as the firing of a gun.
