State fire crews began a 35-acre prescribed burn on Anchorage’s Hillside May 12 between Hilltop Ski Area and the Prospect Heights Trailhead, expecting visible smoke and temporary trail closures.

Better knowledge and mapping of existing infrastructure is leading to a new estimate of future thaw costs under varying climate scenarios.

The Knik Tribe's monitoring program for paralytic shellfish poisoning was paused in April as the federal government investigates its legitimacy for funding.

According to an internal budget document, the Trump administration is seeking to end nearly all of NOAA's climate research.

A young wolverine found in a shed in downtown Turku in January was still exceptional. “Wolverines occasionally wander around southwestern Finland.

We have a lot of phenological events, but how much snow and when it falls are not part of that scheme. If you did not mulch last fall, you are going to lose some and maybe many of your perennials.

Thunderstorms are rare in the cold, dry Arctic, but a surprising event in August 2019 has scientists rethinking how these storms form in polar regions. A team of researchers from the University of Science and Technology of China has uncovered new insights into this phenomenon.
