“That methane could be released episodically along faults that break through the permafrost due to partial melting of ice,” How can ice melt at -60° though, unless the Martian temps climb past 0°?
Wide range of temperatures on Mars. "Surface temperatures may reach a high of about 20 °C (293 K; 68 °F) at noon, at the equator, and a low of about −153 °C (120 K; −243 °F) at the poles." https://en.wikipedia.org/wiki/Climate_of_Mars …
