Question

Which greenhouse gas, despite a far lower atmospheric concentration than CO2, has a global warming potential roughly 25-30 times higher than CO2 over a 100-year horizon and is significantly emitted from paddy fields and livestock enteric fermentation?

Methane CH4, released from anaerobic decomposition in flooded paddy fields and from enteric fermentation in ruminant livestock, has a global warming potential around 25-30 times that of CO2 over a century. Nitrous oxide has an even higher GWP but arises mainly from nitrogenous fertilizer use and soil microbial processes, not primarily paddylivestock.
