Eight hundred meters below the West Antarctic Ice Sheet, microbes in subglacial Lake Whillans create organic carbon that helps power the Southern Ocean’s vast food chain.

Organic Matter in Arctic River Shows Permafrost Thaw
Samples from two waterways in northern Siberia—the main stem of the Kolyma River and a headwater stream in the river’s watershed—indicate the differing sources and ages of carbon they contain.
Reforestation as a Local Cooling Mechanism
Reforestation has been shown to cool surface temperatures, and a novel study suggests it may also reduce air temperature up to several stories above the ground.
Floating Patches of Soil Nutrients in Soil Help Explain Arctic Thawing
Nutrient-rich diapirs have a complex relationship with soil microbes and play an important role in carbon and nitrogen nutrient cycling, making them crucial for understanding feedbacks in the Arctic.
Florida Coastlines Respond to Sea Level Rise
For more than a century, carbon burial rates have been increasing on some southern Florida coasts. Scientists now verify this trend and propose an explanation.
Toward Forecasting Crop Productivity and Carbon Flux Anomalies
Quantifying reductions in U.S. Midwest crop productivity and carbon uptake due to 2019 flooding using combined satellite observations of solar-induced chlorophyll fluorescence and atmospheric CO2.
Basalts Turn Carbon into Stone for Permanent Storage
Scientists have shown that mineral carbonation can permanently capture and store carbon quickly enough and safely enough to rise to the challenge of climate change.
Early Sprouting of Leaves Enhances Northern Hemisphere Warming
As leaf out has been advancing 4–5 days per decade, scientists say the effect of vegetation on climate remains poorly understood.
Human Composting Is a Greener Way to Go
Our environmental impact doesn’t go away when we die, but there’s a way to make that impact a positive one.
Microbial Influences on Subduction Zone Carbon Cycling
An innovative collaboration is investigating how geobiological processes alter fluxes of carbon and other materials between the deep Earth and the surface.
