This analysis explores the effects of climate change on the Western United States, emphasizing the increase in mean annual temperatures and its impacts on regional hydrology and ecosystems. With a particular focus on salmonid fisheries, the paper discusses how altered snowpack dynamics, stream temperatures, and increased wildfire activity threaten aquatic habitats. The findings suggest significant implications for water resource management and biodiversity under ongoing climate change.
