Gravel-bed rivers and their floodplains are the lifeblood of ecosystems and need to be allowed to run and flood unimpeded if species are to be protected and communities are to cope with climate change, a ground-breaking scientific study has found.

New research suggests that maritime glaciers in the far northwest might survive, but more than two-thirds of Canada’s existing glaciers in British Columbia and Alberta could be lost altogether by 2100.

In late winter, when the high mountains of Wyoming, Montana and Idaho are buried in snow, female wolverines in hidden dens give birth to one or two pure white kits. Scientists suspect the snow helps insulate the kits and protect them from predators like wolves, which might explain why...

Throughout late March and into April, much of the West experienced unseasonably warm days. Then, in late April, temperatures plummeted in Southwest Colorado’s San Juan Mountains and more than 2 feet of wet, heavy spring snow fell. Suddenly, ski boots were out again and for a day or...

Geoscientists have for the first time revealed the magma plumbing beneath Mount St. Helens, the most active volcano in the Pacific Northwest. The emerging picture includes a giant magma chamber, between 5 and 12 kilometers below the surface, and a second, even larger one,...

Decades of debate over whether or not to list snow-loving wolverines on the Endangered Species Act (ESA) have finally come to an end. A federal judge recently overruled the government's refusal to list the animals and ordered wildlife officials to take immediate action.

If climate change continues as it has been and warming trend predictions are correct, the massive icefield that feeds Alaska's Mendenhall Glacier - the Juneau Icefield - might be gone by 2200. The findings were published in a recent study by researchers from the University of Alaska...

In a large forest land in British Columbia is a growing miracle: clusters of large trees that have grown as an effect of climate...

In a new study in Environmental Research Letters, a team of hydrologists that includes University of Utah professor Paul Brooks answers that question by simulating isolated climate change effects on Rocky Mountain stream systems, varying the type of...

Seated in a circle around the conference room at Blue Mountain Community College in Pendleton, about 30 people gathered Saturday afternoon to discuss the effects of climate change on local forests and what can be done to make the landscape more adaptable.
