Ja, I mostly dismiss the notion of observational error, but agree that we
don't know very well all the chemistry when the surface is over 500 degrees.
I am intrigued with the notion that some extremophile might have evolved
there and devoured the methane. Recall that is pretty much what happened on
this planet: life originally evolved here in a reducing environment, rich in
methane and other organics. The early plants and beasts devoured much of
that methane and the other *anes. Then that crowd were later poisoned by
oxygen. We are the freaks that escaped that poisonng event.
Wouldn't it be wicked cool if that's what is going on?
