The amount of carbon dioxide escaping from rivers and streams into the atmosphere is much larger than previously thought, according to a new study that maps for the first time the flux of CO₂ from inland waters worldwide. Published in the journal Nature, the research reveals the major role these waterways play in the global carbon cycle, the authors said.

“This study solidifies the significance of inland waters as conduits of exchange and provides a framework for inclusion of this exchange in regional and global studies,” said lead author Peter A. Raymond, a professor of ecosystem ecology at the Yale School of Forestry & Environmental Studies (F&ES). “Understanding how ecosystems exchange carbon is important, as they currently offset a significant percentage of emissions caused by human activity.” (more…)

*Significant amount of carbon in land is leaking into streams and rivers, then to the atmosphere*

Rivers and streams in the United States are releasing substantially more carbon dioxide into the atmosphere than previously thought.

This according to researchers publishing their results in the current issue of the journal Nature Geoscience. (more…)
