Microbes might be gatekeepers of the planet’s greatest greenhouse gas reserves
The planet produces vast amounts of methane gas through abiotic processes deep inside the planet. There are no organic processes involved in this. This methane travels up until it is released into the atmosphere. And logically, the volumes of methane so released must be more than an order of magnitude bigger than what we assumed so far. But methane concentration in the air is so lo we need pats per billion to put a number to it. This means that the atmosphere’s capacity to beak up methane once its gree is much bigger than we assumed so far. Don’t worry about methane hydrates. The planet can deal with them and has done so many times in the past.
Watts Up With That?
