Seismometers Provide Fuller Picture of Los Angeles Groundwater
A new method to evaluate deep aquifers shows even torrential rains haven’t fully replenished groundwater beneath Los Angeles.
Deep Groundwater Might Be a Sustainable Solution to the Water Crisis
Scientists are finding fresh groundwater buried deep underground, but questions remain about the scale of these resources, how they’re resupplied, and whether they can be used sustainably.
Megadroughts Have Grown in Size and Scope
A new study maps and ranks the largest, longest-lasting, and most severe multiyear droughts from 1980 to 2018.
Boreal Forests May Be on the Move
A new model shows a tendency for tree cover to decline in warmer areas and increase in colder ones.
Flint, 10 Years Later
In the decade since the start of the Flint water crisis, policymakers and communities have made improvements to the lives of residents, but opportunities for progress remain.
What’s On the Horizon for Open Access Geoscience Books?
On the first anniversary of their partnership, AGU and the Geological Society of London reflect on the GeoHorizons series and why open access books are valuable for the geoscience community.
Fiber-Optic Cables Used to Measure Changing Soil Moisture
Scientists are using seismic techniques to measure soil moisture. Their results show that recent droughts in California depleted water in the shallow subsurface.
Water Scarcity Likely to Increase in the Coming Decades
Hydrological modeling suggests that by 2100 more than 65% of the world’s population might, at least sporadically, lack access to clean water.
Potential Relief for the Colorado River’s Near Future
A new study reveals that precipitation could boost the iconic river’s flow in the next couple of decades despite the deleterious effects of warming temperatures due to climate change.
