Decreasing Habitat for Coldwater Fish

Decreasing Habitat for Coldwater Fish

Increasing air temperatures lead to rising water temperatures, which increase stress on coldwater fish such as trout, salmon, and steelhead. August average air temperature above 70°F is a threshold above which these fish are severely stressed. Projected temperatures for the 2020s and 2040s under a higher emissions scenario suggest that the habitat for these fish is likely to decrease dramatically.1,2,3,4  Image Reference: University of Washington5
