The methane absorption was strongest in the tropical forests, probably because microbes thrive in the warm wet conditions found there.

It’s long been thought that soil is the only effective terrestrial methane sink, as certain microorganisms use methane as a food source, but similar creatures live under a tree’s layer of bark, meaning that not only do our woody cousins withdraw CO2 from the atmosphere and store it in their roots, but also remove methane as well, about as effectively or perhaps more so than soil.
