The University of Alaska Fairbanks released a new report this week highlighting environmental changes and extremes that impact Alaskans and their livelihoods. “Alaska’s Changing Environment” provides people with timely, reliable and understandable information on topics ranging from temperature and precipitation changes to salmon and polar bears.

Nitrogen oxide emissions from soil in California's Salton Sea air basin are 10 times larger than state estimates, finds UC Davis study of rural Imperial and Coachella valleys.

In two recent papers, University of Illinois Urbana-Champaign researchers and their collaborators found that emissions from streams are largely derived from nitrification processes in agricultural soils. Further, they found that stream emissions make up a much greater portion of the annual nitrous oxide budget than previously known.

From 23 percent less in the northern Alps to a decrease of almost 50 percent on the southwestern slopes: between 1920 and 2020, snowfall across the entirety of the Alps has decreased on average by a significant 34 percent. The results come from a study coordinated by Eurac Research and were published in the International Journal of Climatology. The study also examines how much altitude and climatological parameters such as temperature and total precipitation impact on snowfall.
