So can we now let the cows fart in peace?
Pull my finger!
Not a chance. Doesn't fit the desired narrative.
"Old" methane being released is nothing new.
In fact, methane hydrate suddenly breaking off the ocean floor and gasifying on its way to the surface has been postulated as a cause for the unexplained disappearance of ships via swamping and sinking.
Which came first?
Increasing temperatures melt ice to release trapped “old Methane” which increases the greenhouse gasses or increased greenhouse gasses cause temperatures to rise.
