In the Madden-Julian Oscillation, shear forces caused by air layers slipping and sliding near the equator play a critical role in forming enormous thunderstorms and monsoons.
In the Arctic, drones and tethered balloons can make crucial atmospheric measurements to provide a unique perspective on an environment particularly vulnerable to climate change.
Measurements of light-absorbing carbon particles made during an Arctic research expedition could improve understanding of their effects on the Arctic climate.
A training initiative in Europe opens doors for young scientists, promoting collaboration and broadening their skills with unique opportunities in atmospheric research.
Researchers construct a world where nuclear energy everywhere is replaced with coal, with stark consequences for human health and the environment.
A prototype ShakeAlert early warning system approaches alert-ready status as the administration issues an executive order on federal earthquake standards.
AGU members and others in the news.
A seismically quiet part of the Aleutian Subduction Zone may have caused tsunamis in the past—and may cause future tsunamis that could travel across the Pacific Ocean.
Researchers mine seismic wave data to elucidate the stress relief system of the Main Marmara Fault beneath Turkey's inland sea.
Researchers demonstrate the value of combining GPS and satellite data on vertical motion of the Earth's surface with tide gauge measurements to track rising sea levels.
New research provides evidence that plants that flower earlier in the year because of climate warming experience more frost damage and have less reproductive success.
Australia is a continent of extremes, and researchers find that some ecosystems are better equipped than others to deal with the country's characteristic extreme climatic variation.
A case study of the Irish Sea evaluates the use of ocean color data to measure the optical properties of sedimentary particles in offshore waters.
Rain falling on bare soil can form a hard crust that prevents further infiltration. But do these crusts worsen land degradation or help to prevent it?
Researchers identified 11 different interglacial periods over the past 800,000 years, but the interglacial period we are experiencing now may last an exceptionally long time.
If rain falls on an ocean and nobody's there to see it, how can we determine its effect on the Earth's climate? A new study shows us how space-based radar could help.
A new algorithm improves the accuracy of Pacific and Indian Ocean surface temperature measurements by the Japanese geostationary satellite Himawari-8.
Scientists examine the role of variables like tides and suspended sediment concentration to improve methods of evaluating coastal wetlands and how they may respond to future sea level rise.
A computer simulation shows a net increase in primary production by phytoplankton if climate change were mitigated by 2200 but also indicates big changes in the makeup of those species.
In the 2000s, the North Atlantic stopped absorbing as much atmospheric warmth. However, the ocean lost only a little heat—the rest was held deeper below the surface by altered circulation patterns.
New research shows that increased levels of carbon dioxide in the oceans cause changes that alter key nutrients essential to the reproduction of animals low on the food web.
Scientists testing the quality of floodwater in a Florida city find potentially harmful bacteria.
An encouraging new study finds that solar storms don't propagate chaotically like hurricanes—their arrivals are more predictable, which should make it easier for our planet to prepare for them.
For years, scientists have proposed upgrading the National Oceanic and Atmospheric Administration's solar storm forecasts to account for their tilt as they streak toward Earth. But does it help?
Mysterious plasma waves from space are generating displays of aurora near Earth's poles.
Real-world data drive a simulation that successfully predicts Sun structures and interplanetary solar wind dynamics.
Study reveals structures along the Alaskan convergent margin capable of generating a powerful tsunami directed toward the United States's West Coast.
Scientists used drones, seismic data, and eyewitness accounts to figure out what unleashed an unthinkably large landslide on a spring day in Colorado.
