Nonlinear concepts have evolved and become increasingly applicable to a wide range of geoscience inquiries, thus setting the stage for exciting new advances during AGU’s next 100 years.
Research Spotlights
Research spotlights are plain-language summaries of recent articles published in AGU’s suite of 24 journals.
No Underground Magma Ocean on Jupiter’s Fiery Moon?
A new study suggests alternative explanations for Io’s unusual magnetic field.
How Will the Jet Stream Respond to Future Warming?
Simulations that test different approaches to modeling radiation suggest a commonly used scheme fails to fully capture changes in midlatitude circulation associated with climate change.
Did a Volcanic Eruption in 1783 Change the Climate in Europe?
A new model of the Laki eruption in Iceland suggests that normal climate variability was to blame for the anomalously warm summer.
Detecting Carbonates on the Surface of Mars
A new study shows how a warm, wet climate weathered rocks on early Mars.
Can Patches of Cold Air Cause Thunderstorms to Cluster?
Small-scale collisions between pools of cold air may play an important role in organizing hurricanes and other crucial atmospheric phenomena, according to newly developed conceptual models.
In Pennsylvania, Methane Emissions Higher Than EPA Estimates
Although methane emission estimates from underground coal production appear to be accurate, the calculated emissions from natural gas production are underreported.
New Global Analysis Reveals Amount of Sediment on the Ocean Floor
Researchers calculate that there are ~3.37 × 108 cubic kilometers of sediment on the world’s ocean floor.
A New Look at Winter Air Quality in the Northeastern U.S.
Past studies underestimated a major pollution source, particularly in rural areas.
A Look at How Long-Banned PCBs Persist in the Ocean
A new study tracks how climatic factors like sea ice cover and ocean circulation affect the life span and distribution of polychlorinated biphenyls in the world’s oceans.
