Tropical methane emissions contribute largely to recent changes in global atmospheric methane growth rate

A recent study reveals that tropical terrestrial methane emissions account for over 80% of the observed changes in global atmospheric methane growth rate between 2010 and 2019. This finding underscores the significant impact of methane on climate change, with methane concentrations more than doubling since the pre-industrial era.
