Good Point.. though there might have been a Gotcha! with CH-4
Sublimation
..It's not just about Shrink-talk about homo-sap weirdness :^>
Looks like CH-4 passes as, nothing (over Eons in the mere Arctic) is likely to have hit -200º C--with damn near perfect insulation
unto (our possibly last-) millennium. And necessity of 1/10 atmospheric pressure, to boot.
Gotta love Chemistry; it's all about Physics.
But 'Muricans are all about Sports; 'Climate' is way down such lists, I've noted.

If solid methane at 1 atm is heated while the pressure is held constant, will it melt or sublime?
"Starting at P = 1 atm and moving horizontally, liquid region is reached at T 180C Then into the gaseous region, at T 160 C.
So, solid methane melts
In order for methane to sublime, the pressure must be below the triple point pressure"
