Featured Research

Drying, not just dry weather, will dry out central US
Climate change will bring water shortages to many parts of the United States, but today’s least rainy regions are not always the most at risk. Heat-driven evaporation from soil and plants may be a bigger future problem than lack of rain for northern Midwest states, according to a new analysis of water vulnerability and its sources across the contiguous states under high and low carbon emissions. [Geophysical Research Letters research]

Known unknowns and unknown unknowns of drinking water contamination
A review explores the state of the science on “contaminants of emerging concern,” an ever-expanding class of potential chemical and biological hazards, and how future changes in weather, population and demographics could complicate the availability of potable water. [GeoHealth review]

Forestation is not enough to cool the planet
Growing trees can bank a lot of carbon, but not enough to significantly mitigate global warming through carbon dioxide removal if carbon emissions remain high. [JGR Biogeosciences research]

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 Europa, one of Jupiter’s moons — perhaps among the most promising places in our solar system to search for life. [Eos research spotlight][AGU Advances research]

Glaciers rise and fall — and melt — with tides
The effect of ocean water creeping beneath Greenland ice is stronger than scientists realized. [Eos research spotlight][Geophysical Research Letters research]

Plants reveal the history of Earth’s largest tropical ice cap
Rooted plants buried by advancing outlet glaciers illustrate rapid changes in the extent of Quelccaya Ice Cap in Peru during the Holocene. [Eos editors’ highlight][JGR Earth Surface research]
