Research Spotlights
Research spotlights are plain-language summaries of recent articles published in AGU’s suite of 24 journals.
Glaciers Rise and Fall—and Melt—with Tides
The effect of ocean water creeping beneath Greenland ice is stronger than scientists realized.
Scientists Investigate How Heat Rises Through Europa’s Ocean
A new study examines how heat may be transferred from the mantle, through the ocean, and into the icy crust of one of Jupiter’s moons—perhaps among the most promising places in our solar system to search for life.
Uncertainty Abounds in Seeding the Sky to Fight Climate Change
Some scientists have suggested injecting solid particles such as alumina, calcite, or even diamonds into the atmosphere to temporarily limit climate warming. But new research shows there are still big unknowns.
Researchers Develop Mexico’s First Comprehensive Greenhouse Gas Budget
A new study delves into 2 decades of data to create a comprehensive quantification of carbon, methane, and nitrous oxide sources and sinks that could help guide climate policy.
Seawater Dynamics in an Underexplored Antarctic Fjord
Wind is the major driver of salinity changes within the narrow, glacier-fed cove.
Iron Snow Ebb and Flow May Cause Magnetic Fields to Come and Go
Lab experiments find that iron crystals in planetary cores may form in bursts, causing periodic dynamos.
Ocean Warming Sets the Stage for Dangerous but Predictable East Africa Droughts
Scientists have uncovered a connection between temperature gradients in the Pacific Ocean and deadly but predictable consecutive dry spells in East Africa.
