Yellow Detritus in the Oceans May Help Reduce Warming

Aaron Sidder, freelance science writer by Aaron Sidder 25 September 20181 February 2023

Dissolved organic matter in the oceans absorbs light near the water’s surface, leading to cooler waters that may help mitigate regional climate warming.

Budgeting Ozone-Depleting Emissions from Coastal Tidal Marshes

Aaron Sidder, freelance science writer by Aaron Sidder 6 September 201824 February 2023

Brackish wetlands and their salt-tolerant vegetation are significant methyl halide emitters. The natural emissions add chlorine and bromine to the stratosphere, which break down ozone.
