Soil respiration—the flow of CO2 from the soil surface to the atmosphere—is one of the largest carbon fluxes in the terrestrial biosphere.

New analysis indicates that emissions from abandoned mines will contribute to higher emissions than previously thought.

Early achievement of net-zero greenhouse gas emissions in California brings much larger health benefits than economic cost.

Existing techniques to detect pertechnetate in the environment have drawbacks. PNNL’s redox sensor technology uses a gold probe to accurately and efficiently measure low levels of pertechnetate—and possibly other contaminants—in groundwater

A new procedure for estimating sunlight reflection provides insight into feedbacks that affect Arctic warming.

Tower, aircraft, and satellite observations combined to evaluate weather forecast model.

Nighttime interaction between Bay Area pollution and biogenic isoprene led to efficient formation of secondary organic aerosols.

Tree presence impacts how soils respond to temperature change in coastal forest.

An integrated water model quantifies the impact of water management on thermoelectric power plant generation.

Scientists are exploring ways to derive more accurate predictions that can help with preparations for changing sea levels

A new study examines how back how back-to-back extreme events can affect a forest landscape.

Small increases in irrigated and rainfed crop production across regions where water remains plentiful could help keep food shelves stocked worldwide.

A new data system—gcamdata—with its robust, clear, and easy-to-use application, was developed to be applied to a variety of Global Change Assessment Model scenarios.

Agent-based models of water resource management can include the interaction between human-engineered systems and natural processes

Research software aims to formulate an accurate way to explore feedbacks among socioeconomics, Earth system changes, and crop yield changes
