Title: : Patterns and drivers in methane emissions across rivers and streams under climate change scenarios
Abstract:
Methane is a powerful greenhouse gas whose atmospheric concentrations have tripled since the industrial period. Recent evidence suggests that global warming has exacerbated methane emissions from freshwater ecosystems, thereby introducing a positive feedback loop into the global climate system. Streams and rivers are integral components of freshwater. Recent assessments have highlighted the importance of streams and rivers in the global methane cycle. Yet, for these water bodies, the drivers of CH4 emissions remain highly uncertain. This research aims to explore the hydrological drivers influencing methane emissions in rivers and streams. By utilizing the Global Methane Database, patterns and relationships between methane emissions and river and stream properties will be investigated. By understanding these dynamics, the research aims to contribute to the knowledge of methane production and consumption in aquatic ecosystems, providing insights into the implications of climate change and ecosystem management.
