The western bumble bee was once common in western North America, but increasing temperatures, drought, and pesticide use have contributed to a 57% decline in the occurrence of this species in its historical range, according to a new U.S. Geological Survey-led study.
Snow-capped mountains aren’t just scenic – they also provide natural water storage by creating reservoirs of frozen water that slowly melt into watersheds throughout the spring and summer months. Much of the Western U.S. relies on this process to renew and sustain freshwater supplies, and new research underscores the impacts of extreme weather conditions on this annual cycle.
New research shows that the wettest and most extreme winter storms in the Western United States are only growing wetter and larger. These powerful storms are changing shape in a warmer world, sprawling to drench more land while simultaneously growing more intense at their cores.
Climate projections reported by ExxonMobil scientists between 1977 and 2003 were accurate and skillful in predicting subsequent global warming and contradicted the company’s public claims, a new Harvard study shows.
The U.S. Fish and Wildlife Service this week announced the completion and publication of the final recovery plan for the Meltwater Lednian stonefly and Western Glacier stonefly.
Douglas-fir trees will likely experience more stress from drier air as the climate changes than they will from less rain, computer modeling by Oregon State University scientists shows.
Researchers project that most glaciers in western Canada will be gone in 80 years.
More than a century of preserved fish specimens offer a rare glimpse into long-term trends in parasite populations. New research from the University of Washington shows that fish parasites plummeted from 1880 to 2019, a 140-year stretch when Puget Sound — their habitat and the second-largest estuary in the mainland U.S. — warmed significantly.
Oregon continues to face new and enduring hazards related to climate change, but opportunities for adaptation and mitigation are also expanding, the latest assessment released by the Oregon Climate Change Research Institute indicates.
