A 3-year project documents how climate change is affecting the sequestration of decades-old mining by-products in Canadian lakes.
Hazards & Disasters
Explosive Volcanic Eruption Powered by Water-Saturated Magma
Little seismic unrest preceded the 2014 eruption of a stratovolcano in Indonesia, which suggests that the eruption was kick-started internally by volatile-triggered overpressure.
How Are Microplastics Transported to Polar Regions?
New modeling indicates that global subsurface ocean currents distribute submerged microplastics along very different routes than those traveled by floating plastic debris.
Artificial Intelligence May Help Predict El Niño
Deep learning techniques give scientists the longest–lead time forecasts yet.
AGU Releases Report to Address Flooding in Communities
The Surging Waters report shows how science empowers us to mitigate the impacts on people and property in communities around the United States.
“Glass Pearls” in Clamshells Point to Ancient Meteor Impact
Research suggests that the spherical structures, smaller than grains of sand, may be microtektites, but additional investigations are needed to verify their identity.
The Coming Surge of Rocket Emissions
With the space industry’s rapid growth, rocket exhaust will increasingly accumulate in the atmosphere. How this accumulation might affect the planet is unknown—because we’re not taking it seriously.
Podcast: Volcano Disaster Prepping
Third Pod from the Sun talks with volcanologist John Ewert, a founder of the U.S. Geological Survey’s Volcano Disaster Assistance Program.
Distant Quake Triggered Slow Slip on Southern San Andreas
A high-resolution map of surface displacements indicates that the 2017 Chiapas earthquake caused substantial creep along a segment of the San Andreas Fault, located 3,000 kilometers away.
As Arctic Sea Ice Disappears, What Happens to Ecosystems?
The northern Bering Sea is experiencing record-setting low winter sea ice levels, which are impacting plankton, fish, and other animals in the region.
