Scientists have discovered that uncertainty about the landscape beneath Antarctica’s kilometre-thick ice sheet can influence future sea-level forecasts just as much as the difference between...

Early in the morning of 10 August 2025, a >64 × 106 m3 landslide struck Tracy Arm fjord in Alaska. The landslide was preconditioned by glacial retreat caused by climate change. The resulting 481 m run...

These two missions were selected for continued development as part of NASA’s Earth System Explorers Program, which conducts principal investigator-led Earth

After turning off ChatGPT’s ‘data consent’ option, Marcel Bucher lost the work behind grant applications, teaching materials and publication drafts. Here’s what happened next.

The Prudhoe ice dome disappeared during a warm period 7000 years ago. Global warming could cause similar temperatures by 2100, showing the Greenland ice sheet’s vulnerability

Iceberg calving accounts for about half of Antarctic ice-shelf mass loss. We used satellite imagery to analyze annual ice-shelf front changes and major calving events over eight years from austral sum...

Fieldwork can be deadly: heads of expeditions must be taught how to cope in a crisis.

A combination of palaeoclimate proxies and simulations shows that a common mechanism controls El Niño variation in cold and warm states, which supports expectations of more extreme El Niño occurr...

Access federally-supported data visualizations and resources on regional sea level changes and sea level rise in the U.S.

A pioneering mission into a mysterious and violent world may reveal ‘speed bumps’ on the way to global coastal inundation

A new Greenland map suggests how geology might shift and twist below the ice

The story of Greenland keeps getting greener—and scarier. A new study provides the first direct evidence that the center—not just the edges—of Greenland's ice sheet melted away in the recent geologica...

Advances in remote sensing offered an opportunity to redraw Greenland’s geologic map for the first time in 15 years.

An open source, global canopy height dataset and a foundational AI model for a more accountable carbon market.

Hundreds of support staff keep Antarctic research stations running. For decades, workers including me have had little to no protection from sexual harassers and stalkers
