As the name implies, California market squid are often sold in stores and typically found between Baja California and Monterey Bay. So, the squid’s periodic appearance in the Gulf of Alaska – about 745 miles north of its expected range – has given researchers pause.

Change can be hard, especially when it involves soaring summer temperatures, mega-droughts, invasive species and other items from the list of unpleasant outcomes of climate change. In the Western U.S. where skiing, hiking, biking, hunting and other forms of outdoor recreation are core to many people’s lives, and where local economies rely on income generated by these activities, the impacts are already difficult to ignore.

A first-of-its-kind, eight-year study has found widespread and frequent lead poisoning in North American bald and golden eagles impacting both species’ populations.

European green crabs feast on shellfish, destroy marsh habitats by burrowing in the mud and obliterate valuable seagrass beds. The invasive species also reproduces quickly, making it a nightmare for wildlife managers seeking to control its spread in Washington’s marine waters.

The drought that has enveloped southwestern North America for the past 22 years is the region’s driest “megadrought” — defined as a drought lasting two decades or longer — since at least the year 800, according to a new UCLA-led study in the journal Nature Climate Change.

California’s native salmon have been harmed by more than a century of mining, dam building, floodplain reclamation, fishing pressure, hatchery practices, and introduced predators. These stressors have undermined the resilience of California’s native salmon to the accelerating effects of climate change, new research shows.

In a new study, University of Montana researchers found that climate change drives native trout declines by reducing stream habitat and facilitating the expansion of invasive trout species.

The year 2021 was marked by extremes across the U.S., including exceptional warmth, devastating severe weather and the second-highest number of billion-dollar weather and climate disasters on record. 

The supply of farmed seafood such as salmon and mussels are projected to drop 16 per cent globally by 2090 if no action is taken to mitigate climate change, according to a new University of British Columbia study.
