A Drier or Wetter Future for Southwestern North America?
Bhattacharya et al. present evidence that expansion of the North American Monsoon explains a wetter southwest in the mid-Pliocene and suggest this mechanism can explain current monsoon variations.

Differential Evolution of the Pacific Oxygen Minimum Zones
The latest generation of Earth System models simulate an expansion of the oxygen minimum zones in the Pacific, but their inner core, where oxygen levels drop to near zero, contracts in the future.

Winter Arctic Heatwave Drives Summer Impacts in Siberia
A cascade of land-atmosphere interactions resulting from a winter heatwave in Siberia led to significant summer impacts that further exacerbated the heatwave effects on the region.

Why Do Fluvial Valleys Behave So Differently?
Source: AGU Advances Editors’ Highlights are summaries of recent papers by AGU’s journal editors. The shape of fluvial valleys results from the complex interaction between climate and the local environment. Our current knowledge suggests that river discharge and valley-wall lithology are the main controls on valley width. Yet, current models based on these observations fail […]

Measuring the Microstructure of Snow from Space
There is more to snow than flakes. Microwave measurements are shown to be capable of illuminating the microstructure of snow in ways that will improve our ability to monitor snow fields from space.
