Release of methane permafrost https://en.wikipedia.org/wiki/Clathrate_gun_hypothesis Not all ice is made from water. Some ice is frozen methane. If you melt it, you'll release methane. Atmospheric methane is good a trapping heat (aka greenhouse gas). That heat warms the atmosphere, which melts more ice, which includes methane ice, which in turn releases methane, that heats the atmosphere more. In this way you have a self-reinforcing effect where before you know it you have an exponential release of methane/exponential temperature increase and an extinction event like the Permian–Triassic one. https://www.youtube.com/watch?v=6Z6RIQ0Bw-E |
