Budgeting Ozone-Depleting Emissions from Coastal Tidal Marshes
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.

Brown Carbon from Increased Shipping Could Harm Arctic Ice
Emission from a ship’s engine gives clues to how much light-absorbing molecules may build up on and above snow and sea ice. Such emissions are likely to increase as more ships venture into the Arctic.
