Are there any theories as to why the methane seems to dissipate so quickly?
Still no subsurface Martian cows. But otherwise, the story of methane on the red planet gets more interesting.https://www.nytimes.com/2019/04/01/science/mars-methane-gas.html …

Yes. 1) perhaps methane-destroying reactions are occurring not just when gas molecules collide but also on the surface of dust grains, which might be much more efficient. 2) methane-eating microbes.

"Still no subsurface Martian cows"...THAT WE KNOW OF. I, for one, am not giving up hope.

Me, neither.

“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 …

I'm always a bit confused about why it has to be created currently... couldn't there just be an underground reservoir that periodically leaks methane to the surface? The processes destroying methane are active above ground, not below, after all...

You're right. It would have been better for that sentence to have said the methane was released recently.

The problem is that we don’t view planets as living organisms.
