A publication from Alaska Center for Climate Assessment and Policy at the University of Alaska Fairbanks details many of the changes and effects.

In Southeast Alaska, the changing climate means more deadly landslides, and in Anchorage, more heavy-snowfall events, according to Alaska Center for Climate Assessment and Policy’s report.

In the future, a study projects, early-season snow will be too paltry for biologists to spot moose from the air during the fall in most of the animals’ Alaska habitat.

Biologist Stan Boutin with the University of Alberta in Edmonton has spent 30 years studying a population that lives in a square kilometer of forest between Haines Junction and Kluane Lake in the Yukon.

Starting next month, Natalia Ruppert will begin working for the U.S. Geological Survey’s ShakeAlert program in the Pacific Northwest.

Barnes retired this year after a rich career in a quirky place that fit.

Study reveals dramatic increases since the late 1980s, signaling potential future stress for bears already coping with a warming environment in Alaska and Siberia.

If geologists can find pockets and figure out how to mine them, a hydrogen plant could power a nearby village that now has diesel generators rattling every second of every day.

Meteorologists rely on the work churned out by people they never see, who feed weather information to supercomputers all over the world.

Weighing as much as a cup of walnuts and resembling a squeaky dog toy, the ermines are easy to underestimate.
