Beyond Up and Down: How Arctic Ponds Stir Sideways
Contrary to common assumptions, Arctic ponds mix in more than one direction. A new study finds that nighttime sideways flows, not vertical mixing, renew bottom waters.
Seeping Groundwater Can Be a Hidden Source of Greenhouse Gases
A new study in the Farmington River watershed shows that groundwater seeps can release 20% of dissolved emissions into the atmosphere before the water joins streams.
Better Monitoring is Needed for Climate Change in the Upper Atmosphere
A new commentary calls for a better understanding of the impacts of climate change and anthropogenic emissions on long-term trends of the middle and upper atmosphere through enhanced observations and monitoring capabilities.
Peatland Plantations in Southeast Asia are Carbon Hotspots
A new study reports a rare set of data on greenhouse gas production and transport for a tropical peatland plantation showing exceptionally high concentrations of dissolved organic carbon.
The Middle East’s First Comprehensive Carbon Budget
The first greenhouse gas budget for Central and West Asia—24 countries, including Yemen, Türkiye, Kazakhstan, and Afghanistan—was just published.
Particulate Pollution and its Climate Impacts During the COVID-19 Pandemic
The impacts of COVID-19 on short-lived pollutants highlight the predominant influence of the transportation sector and the resulting changes in regional climates and ecosystems.
