Where Fire Ends, Chemistry Begins
Once smoke is generated, chemical reactions reshape its gaseous and particulate constituents, altering what travels downwind and what people, ecosystems, and the climate are exposed…
In Appreciation of AGU’s Outstanding Reviewers of 2025
AGU editors recognize the contributions of peer reviewers in 2025, whose expertise and dedication were integral to the advancement of the Earth and space sciences.…
How Can We Make Better Decisions About What Lies Underground?
Geophysical data offer incomplete clues about the subsurface. Bayesian inversion turns them into plausible scenarios and shows which uncertainties matter for real-world decisions.
AGU Launches New Special Collection at the Nexus of Science and Policy
Seven AGU journals are encouraging submissions of policy-related commentaries and research articles, boosting scientists’ voices to decision-makers.
Behind the Veil of Journal Editing
Training tomorrow’s editors today strengthens peer review, builds editorial capacity, and helps safeguard the integrity of scientific publishing.
Decoding Rocks to Reveal What the Critical Zone Hides
Rock physics models translate geophysical measurements into volumetric rock and fluid properties to quantify weathering trends, water storage, and architecture within Earth’s critical zone.
Climate Model Benchmarking: Building Trust and Advancing Science
A critical look at how well climate models work, how to successfully use them, and the anticipated challenges for their next-generation development.
Decoding the Origins of Lightning’s Violent Currents
A compact set of physical equations delivers a unified, first-principles explanation for how lightning’s most destructive surge of current is born, races towards the clouds, and fades.
Introducing Research Letters in Paleoceanography and Paleoclimatology
Paleoceanography and Paleoclimatology now offers Research Letters, a new format for brief, timely, scientific communications, launched on the journal’s 40th anniversary.
Forty Years of Looking to Earth’s Past to Understand Its Future
From ancient greenhouse worlds to ice ages, Earth’s past offers vital clues to its future. Explore the 40th anniversary special collection from Paleoceanography and Paleoclimatology.
How Bubbles Reshape Air-Sea Gas Exchange
Bubbles produced by breaking waves provide an important but often overlooked pathway for exchanging carbon dioxide, oxygen, and other gases between the ocean and atmosphere.
The Hidden Costs of Mining River Sand
River sand and gravel fuel global construction, but their extraction is reshaping rivers, ecosystems, and communities faster than sustainable management can keep pace.
Why Healthy Soils Matter More Than Ever
Soil degradation threatens food security, water resources, biodiversity, and climate resilience. A new article explores its causes, impacts, monitoring methods, and restoration solutions.
Small-Scale Indian Ocean Dynamics Underpin Marine Ecology and Climate
With unique monsoon, mesoscale and submesoscale processes, the Indian Ocean offers critical insights and new challenges to achieving a full understanding of marine environments and the Earth system.
