Featured Research
Bottled water drinkers underestimate price markup over tap
In France, bottled water costs 100 times the price of tap water. But bottled water drinkers are more likely than tap drinkers to perceive this gap to be much smaller, according to a new analysis of 4,003 survey responses. [Water Resources Research]
Canadian taiga will burn hotter and more frequently this century
Warming temperatures and drying can be expected to contribute to rising fire danger and severity throughout Canada’s coniferous forests through the end of century if greenhouse gas emissions continue unabated, a new study based on fire trends from 1976 to 2014 and the latest climate models finds.

Solar Orbiter predicts incoming solar storms
Bursts of plasma from the Sun called coronal mass ejections can damage Earth’s satellites and electric grids. Many of these problems can be avoided with warning of incoming storms, but current models aren’t good at forecasting arrival times and severity. Data from the Solar Orbiter demonstrated for the first time how spacecraft orbiting halfway between Earth and the Sun could improve forecast accuracy and precision, predict the evolution of geomagnetic storms and provide 40 hours of advance warning.

Extreme reservoir water drawdowns, accelerated by climate change, bring environmental drawbacks
Changing climate and water demands are causing more frequent extreme swings in water levels for many lakes, especially human-made reservoirs. A case study at Beaverdam Reservoir in Virginia, USA, tracked impacts on biology, chemistry and aquatic physics during a rapid 36% volume loss over only a single month. Nutrients concentrated at the surface, feeding an algae bloom that dropped oxygen levels as the bloom died. [JGR Biogosciences research]
Urban nature is often plentiful but inaccessible
A novel research framework deepens understanding of urban nature accessibility and highlights progress toward green space goals.. [Eos research spotlight][GeoHealth research]
Preparing to meet a metal-rich asteroid
The recently launched Psyche mission will explore the eponymous asteroid and determine whether it is a fragment of a planetary core or a primordial, metal-rich body. [Editors’ highlight][AGU Advances research]
