A new study in the Baltimore-Washington metropolitan area reveals prior estimates may significantly underrepresent methane emissions, particularly from landfills and natural gas systems.

Volcano in Iceland Is One of the Largest Sources of Volcanic CO2
High-precision airborne measurements, in combination with atmospheric modeling, suggest that the Katla subglacial caldera may be one of the planet’s biggest sources of volcanic carbon dioxide.
A Modeling Toolbox for Permafrost Landscapes
A new resource makes it easier for researchers to explore predictions of how melting permafrost might affect carbon release, wetlands, and river deltas as they evolve and other interacting effects.
What Lies and Waits Beneath Lake Ice?
Rarely made detailed measurements of carbon dioxide and methane under lake ice reveal a story more complex than simple models of gas buildup, with surprising findings for climate change impacts.
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.
Rising Seas Increase Methane Emissions from the Mouths of Rivers
Drowned river deltas exhale large quantities of greenhouse gas, new study finds.
Drones Hunt for Impacts of Oil Exploration on Wetland Emissions
Seismic lines, constructed for petroleum resource exploration, disturb Canadian peatlands, but how can we detect their impact on greenhouse gas budgets?
Carbon Release from Permafrost Erosion Along the Yukon Coast
New findings highlight the need to account for large amounts of ground ice contained in frozen soil when assessing Arctic carbon cycling.
