    We have recently conducted an inverse modelling study and found that both the anthropogenic/thermogenic emissions and biogenic (mainly from animal farming) has cause the CH4 rise since 2006. More information are available here:

    I am happy to see that two independent research arrived somewhat in similar conclusions regarding the importance of agriculture on reduction of CH4 emission. But further attribution is needed for source types and source regions for making specific mitigation policy.
