Carbon flow through inland and coastal waterways, implications for climate

— posted on Apr 07, 2022 11:11 AM

A recent study by an international team of scientists including Raymond Najjar, professor of oceanography at Penn State, found that the flows of carbon through the complex network of water bodies that connect land and ocean has often been overlooked and that ignoring these flows overestimates the carbon storage in terrestrial ecosystems and underestimates sedimentary and oceanic carbon storage.

While climate change is making much of the world warmer, temperatures in a subpolar region of the North Atlantic are getting cooler. A team of researchers report that changes in the wind pattern, among other factors, may be contributing to this “cold blob.”
