Methane is a much better “greenhouse” gas than CO2. There are HUGE pockets of methane hydrates in the ocean floor - somehow they are trapped below the sediments, and folks are trying to come up with ways to make it practical to mine/drill them as a source of energy.
In the geologic past, sometimes these pockets are disturbed and the methane is released in a catastrophic manner that DOES cause problems. “Leakage” from some peat bogs is not that big of a deal.

The above “doomsday” site actually has a good brief description of the methane hydrates in the ocean floor and the effects of 55 million years ago when estimated 20% of them were released.
After the first few paragraphs though they get into the scare tactics. (”If this, if that, then maybe that....and we all die!”)
“In the geologic past, sometimes these pockets are disturbed and the methane is released in a catastrophic manner that DOES cause problems. “Leakage” from some peat bogs is not that big of a deal.”
So we should mine the methane, burn it to C02 + H20. That would reduce global warming, right?
