Dynamics of methanogenesis and methanotrophy in tropical paddy soils as influenced by elevated CO2 and temperature interaction

► High CO2, temperature and other climatic variables influence production and oxidation of CH4. ► In an incubation study, elevated CO2 increased CH4 production in flooded paddy soils. ► CH4 production increased further by high temperature. ► In contrast, CH4 oxidation was consistently low under high CO2. ► CH4 oxidation decreased further with high temperature.
