Climate-driven Shifts in Quantity and Seasonality of River Discharge over the past 1000 Years from the Hydrographic Apex of North America [PDF]
, 2008 Runoff generated from high elevations is the primary source of freshwater for western North America, yet this critical resource is managed on the basis of short instrumental records that capture an insufficient range of climatic conditions. Here we probe

Glacier Change, Concentration, and Elevation Effects in the Karakoram Himalaya, Upper Indus Basin [PDF]
, 2011 In recent decades the consequences of climate change for Himalayan glaciers has become of great concern. Glaciers in much of High Asia appear to be declining, some at globally extreme rates (Ageta 2001;Oerlemanns 2001).

A New Method for Automatic Glacier Extraction by Building Decision Trees Based on Pixel Statistics
Remote SensingAutomatic glacier extraction from remote sensing images is the most important approach for large scale glacier monitoring. Commonly used band calculation indices to enhance glacier information are not effective in identifying shadowed glaciers and debris-

Mountain goat declines in a protected, interior, native population
EcosphereA shifting climate poses threats to alpine‐adapted species including mountain goats. We used long‐term (12 years) citizen science monitoring data and Bayesian N‐mixture modeling to estimate population trends and drivers of population metrics among ...

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Advanced Functional Materials, EarlyView.While host structures are known to enhance the reversibility and safety of lithium metal deposition, their additional volume and weight often decrease the battery's energy density and specific energy. By combining a lightweight and porous scaffold of electrospun polymer with a thinner separator, this article demonstrates a simultaneous improvement of ...
