Speed of Ice Shelf Rifting Controlled by Ocean-Ice Interactions

by Susan Trumbore 4 March 20244 March 2024

Scientists report the fastest rate of rift extension yet observed for an Antarctic floating ice shelf and explain why it is far slower than rates expected for brittle ice deformation.

Climate Models Often Miss How Plants Respond to Drought

by Rebecca Owen 5 February 202422 March 2024

New research suggests that Earth system models are underestimating the effect of low moisture levels on plants’ abilities to exchange carbon, water, and energy with the atmosphere.

Using Machine Learning to Reconstruct Cloud-Obscured Dust Plumes

by Donald Wuebbles 2 February 20241 February 2024

Satellite-observed dust plumes from North Africa are frequently obscured by clouds, but a new study uses machine learning to reconstruct dust patterns, demonstrating a new way to validate dust forecasts.

Comparing Carbon-Trapping Capacities of Anoxic Basins

by Saima May Sidik 1 February 2024

Low-oxygen regions in the ocean could be prime spots for sequestering biomass—a potential strategy for fighting climate change. But each site has its pros and cons.

Law and Order for Friction and Faults: One Law to Rule Them All

by Peter Zeitler 19 January 202418 January 2024

Faults are made of complex materials with complex behaviors, and having a single model that can predict these behaviors is an advance in understanding deformation and the earthquake cycle.
