On behalf of the Global Carbon Project, we are happy to inform you that a new Global Methane (CH4) Budget has just been published after years of preparation, networking, and synthesis work. The new assessment, published in Earth System Science Data, presents the global CH4 budget arising from both natural and human-induced emissions, and how CH4 is destroyed in the atmosphere by chemical reactions and soil uptake.
You can access the relevant papers, figures and data from HERE. See also an interactive CH4 source emission visualization at this SITE.
