In our current era of rapid climate change, it is critical we understand how every aspect of the Earth system affects carbon cycling. New work by Marisa Repasch and colleagues shows that rivers, under the right conditions, might be able to sequester more carbon in the sediments than released into the atmosphere. However, these findings may reveal how human impacts to rivers will likely increase the amount of carbon released to the atmosphere.
