Inland water is an important source of global methane (CH4) emissions, and CH4 emitted through ebullition accounts for a large proportion of the total CH4 emissions from inland waters. Here, the latest progress in domestic and international research has been systematically summarized to introduce the generation, transport, oxidation, and release of CH4 via ebullition in inland waters as well as the methods and techniques for measuring CH4 ebullition. Subsequently, temporal and spatial variations in CH4 ebullition from global inland water were compared at different temporal and spatial scales. In addition, the mechanisms of the relevant influencing factors in the processes of CH4 generation and ebullition are further summarized, and current development and applications of CH4 ebullition models are discussed. Finally, potential research directions and challenges related to CH4 ebullition from inland water are proposed, aiming to provide a basis for subsequent research on CH4 ebullition, investigation of process and control mechanisms, and model development and estimation in this field.
