Washington State Recreation and Conservation Office, Governor's Salmon Recovery Office produced a visual report that you can scroll through to see how climate change is killing salmon: Washington has several glacial regions that supply just under 500 billion gallons of freshwater each summer. Many ecological systems and organisms, including salmon, rely on this cold, clean water during warmer seasons to keep the streams hospitable ... In addition, warmer air temperatures translate to warmer water temperatures. The cold water needed by salmon is expected to continue to increase in temperature. As temperatures rise, the amount of suitable habitat for salmon shrinks. Below is a series of coupled in-stream (dots) and air (shaded) temperature maps from Climate Impacts Group showing this relationship.
