Upper-Tail Sea Level Rise Projections Hinge on Climate Sensitivity
Researchers analyzed the relationship between Earth’s climate sensitivity and historical/future sea level projections, with a particular focus on the high‐impact upper tail.
Evaluating Climate Model Emulators
Researchers quantified temperature and gas-cycle responses over time of five simple climate models to impulses of carbon dioxide, methane, and black carbon.
Predicting Soil CO2 Emissions from Air Temperature
Soil respiration—the flow of CO2 from the soil surface to the atmosphere—is one of the largest carbon fluxes in the terrestrial biosphere.
Extreme Convective Storms Occur at High Latitudes
Researchers at PNNL and the University of Washington examined storms seen by the GPM satellite and found that deep convective storms have been occurring surprisingly frequently at high latitudes during the warm seasons of recent years.
Polar Imbalance: Understanding Differences in How the Arctic and Antarctic Respond to Increased Greenhouse Gases
This study by PNNL researchers provides an alternative explanation for why the Arctic warms more than the Antarctic.
Calibration and Uncertainty Analysis of Demeter for Better Downscaling of Global Land Use and Land Cover Projections
New study provides a key reference for Demeter users and is expected to help reduce uncertainties in downstream hydrologic and Earth system simulations.
Predicting the Particles that Initiate Freezing in Clouds
To help close the gap between observed and modeled ice-nucleating particles (INPs), researchers simulated concentrations of dust, sea spray, and other types of atmospheric particles within a global atmospheric model.
Urbanization Shapes Thunderstorms Near the Gulf Coast
Urbanization-induced land cover and anthropogenic aerosol changes result in stronger thunderstorms with enhanced precipitation in the Houston area.
Making a Simple Climate Model More Accessible Through Online Visualization
The newly developed Hector user interface (hectorui), a web-based app, provides access to the Hector climate model to anyone with a web browser.
