Now why might the governor of the State of Washington be concerned about global warming?
"Climate change is threatening the clean, cold, and plentiful water in rivers that salmon need to survive.
Climate change has warmed the air across Washington by 0.15 degree Fahrenheit every decade during the past 100 years,
23 a trend that is projected to continue but at an even faster rate, reaching increases of up to 5.3 degrees Fahrenheit every decade by 2090.

As the air warms, glaciers, which store much of the freshwater in the Pacific Northwest, melt and have less cold water to feed streams in the summer when salmon need it the most.
Glaciers are Melting
In Washington, nearly a quarter of Mount Rainier’s and more than half of the north Cascade and Olympic Mountain ranges’ glaciers have melted,
30 and the rate of melting is only expected to increase.
31 Scientists estimate 80 percent of western North America’s glacier ice volume will be lost by 2100."
Climate changes are melting glaciers, decreasing snowpack, and causing rivers to be warmer, all impacting salmon
