Don’t get taken in by the notion that new methane emissions are benign. It is close on three times the size of the global methane cloud 150 years ago, although most of that increase has nothing to do with agriculture. Just accept that only half of the warming effects occur within the first 12 years. The scientists who developed the GWP* equation have not said that new methane emissions are benign. Abraham has enough methane decay in his cloud to almost balance his ongoing emissions so his assessed liability is very small.
