A new study combines historical observations, climate modeling, and data from tree rings to create a fuller picture of historic as well as potential drought conditions.
Research Spotlights
Research spotlights are plain-language summaries of recent articles published in AGU’s suite of 24 journals.
Isotopes Unearth History of Earthquakes in the Apennines
Dating of cosmogenic chlorine isotopes yields long-term estimates of fault activity in Italy, showing that periods of earthquakes and quiescence alternate over millennia.
Solar Power Shortages Are on the Rise
More communities are relying on solar power as a source of renewable energy, but increasing demand and climate change threaten its reliability.
The “Surprising” Effect of Drying Headwaters on Nitrogen Dynamics
Contrary to predictions, spring rains caused a decrease in nitrogen at watershed outflows in Alabama.
Türkiye-Syria Temblors Reveal Missing Piece in Earthquake Physics
Newly discovered aseismic events triggered by the 2023 Kahramanmaraş earthquake may represent a mode of fault slip between earthquakes and slow-slip events that researchers have long been seeking.
When Ice Ages End, Ocean Circulation Fine-Tunes Ocean Heat
New Antarctic ice core data bolster model predictions of ocean heat content during glacials and interglacials.
New Insights into an Enigmatic Form of Magnetic Reconnection
A new study deepens understanding of magnetic field behavior recently discovered by NASA in Earth’s magnetosphere.
“Thirstwaves” Are Growing More Common Across the United States
Like heat waves, these periods of high atmospheric demand for water can damage crops and ecosystems and increase pressure on water resources. New research shows they’re becoming more severe.
El Antropoceno merece reconocimiento oficial, sostienen algunos expertos
La Unión Internacional de Ciencias Geológicas decidió no designar una nueva época geológica, pero el asunto aún no se ha resuelto.
The Rivers That Science Says Shouldn’t Exist
At first glance, these waterways make no sense. A new review article details why they are the way they are.
