Rivers on the Rise: Forecasting Heat Stress for Atlantic Salmon

August 10, 2025

Trends, teleconnections and nonstationary frequency modeling of riverineheatwaves in North American Atlantic salmon rivers (1979–2100).

This study looks at how climate change is affecting rivers where Atlantic salmon live in north eastern North America.

It finds that river water is getting warmer and heatwaves are becoming more frequent, longer, and more intense—especially in summer. By the end of the century, nearly half of these rivers may experience permanent summer heatwaves.

Using advanced models, they predicted these changes and found that large-scale climate patterns like the North Atlantic Oscillation play a big role.

These insights can help guide better river management to protect salmon habitats.
