Rice paddy is a major source of anthropogenic terrestrial methane ( CH 4 ). C hina has the second‐largest area of rice cultivation in the world, accounting for ca. 19% of the world's rice‐producing area. Recognizing the significance of C hina's rice cultivation in the global CH 4 budget, we estimated the CH 4 emissions resulting from irrigated rice cultivation in C hina from 1960 to 2050 using a CH 4 MOD model. The model estim...
