Compared with previous generations, current Earth system models predict that Earth’s climate is more sensitive to carbon dioxide. Where does the increased sensitivity come from?
Research Spotlights
Mapping Nutrient Inputs in the Great Lakes Basin
A new tool links nitrogen and phosphorus applications to land use classifications to better understand where and how much of the nutrients enter watersheds in the U.S. Great Lakes Basin.
Larger Role for Shallow Intermediate Waters in Ocean Circulation
Water masses formed off southeastern Greenland may contribute more than previously thought to the variability of the Atlantic Meridional Overturning Circulation, which strongly influences global climate.
Mapping Martian Dunes from Orbit
New research shows how fast the sands shift on the Red Planet and how useful imagery from different orbiting cameras can be in studies of Mars’s dunes.
Evaluating Cloud Cover Predictions in Climate Models
A new analysis highlights progress in predictions of cloud cover from models that are part of the Coupled Model Intercomparison Project.
River Deltas at the Top of the World
The water that filters through river deltas has a large effect on the Arctic Ocean. A new study explores factors that shape Arctic river deltas and how delta form in turn changes water flow.
Pushing the Computational Limits of Climate Simulation
Researchers apply a superparameterization technique to boost the accuracy and efficiency of climate predictions generated by the Energy Exascale Earth System Model.
“Electron Wings” Can Interfere with Spacecraft Measurements
Spacecraft sometimes produce a form of electrical self-interference as they zip through plasmas in space—a previously unreported effect that may be lurking in old data sets.
Santa Ana Winds and Wildfires Influence Air Pollution
Inhaling particulate matter is hard on human health. New research shows that Southern California’s Santa Ana winds can clear or exacerbate fine-particulate pollution depending on wildfire conditions.
Deciphering Electron Signatures in Earth’s Magnetic Tail
A new analysis of spacecraft data collected near the tip of Earth’s magnetotail sheds light on how geomagnetic activity affects the motion of electrons in this region.
