This paper reports global carbon dioxide (CO₂) evasion rates from inland waters, including streams, rivers, lakes, and reservoirs. The study estimates that streams and rivers contribute 1.8 Pg C yr⁻¹, while lakes and reservoirs contribute 0.32 Pg C yr⁻¹, totaling 2.1 Pg C yr⁻¹. This is higher than previous estimates due to a larger stream and river evasion rate. The study identifies that about 70% of the total CO₂ evasion occurs over just 20% of the Earth's surface, highlighting the importance of these regions. The source of inland water CO₂ is still uncertain, and further research is needed to understand the mechanisms controlling CO₂ evasion globally. The study uses a combination of geospatial data, remote sensing, and hydrological models to estimate the global surface area of inland waters and gas transfer velocities. It also incorporates data on dissolved CO₂ concentrations and pCO₂ values from various sources. The results show that inland waters are significant contributors to the global carbon cycle, with CO₂ evasion rates higher than previously estimated. The study also highlights the importance of wetlands and the need for further research on the distribution of lakes and the role of wetlands in CO₂ evasion. The study emphasizes the need for improved data on CO₂ emissions from inland waters, particularly in regions with limited data. It also calls for further research on the factors controlling gas transfer velocities and the role of different ecosystems in the global carbon budget. The findings underscore the importance of inland waters in the global carbon cycle and the need for continued research to better understand their role in the carbon budget. The study provides a comprehensive analysis of the global carbon cycle, highlighting the significance of inland waters in the exchange of CO₂ with the atmosphere.This paper reports global carbon dioxide (CO₂) evasion rates from inland waters, including streams, rivers, lakes, and reservoirs.
