Salmon and trout anglers across the Pacific Northwest are going to have fewer places to fish over the next 40 years, concludes a new study published this month.
Scientists at the Forest Service's Rocky Mountain Research Station in Boise found that in the summer and early fall, rivers in the Pacific Northwest have already warmed 1.8 degrees Fahrenheit since 1976. That's the same rise measured at the Bonneville Dam over the last 80 years and used in models by climate scientists.
The researchers studied 391 monitoring sites. The temperature pattern gives them confidence the warming trend is going to continue for the next 40 years, said Dan Isaak, the lead researcher. That means salmon and trout are going to have less habitat, and will be replaced by warm-water fish like smallmouth bass.
The study - "Global warming of salmon and trout in the northwestern U.S.: Road to ruin or path through purgatory?" - was done after the 2015 season, when warm temperatures in the Columbia, Snake and Salmon rivers killed off nearly all of the sockeye salmon returning to Idaho's Sawtooth Valley.
Despite the warming, which has been hastened by human behavior, the scientists don't predict habitat loss by itself will send any of the fish species into extinction over the next 40 years.
"It's in the latter half of the century that we have more uncertainty," Isaak said.
The models show the warming trend slowing when the rise in greenhouse gases stops or is reversed. But the science is not as clear about when that will happen, or that it will affect the climate, Isaak said.

It’ll mess up hunting too, right? And raising children and going to church. Seems Alarmist are targeting conservatives... What a yawn.
Good one! I am going to have to borrow that one because it is soooooo descriptive. They have such blind faith in their models which cherry picks just a little over a century of data from 6000 years of recorded human history.
Oh, BS....I live in the PNW....according to MY study we are heading into a glacial cooling period....the candling on Pine trees is about a month late this year. The TREES KNOW SOMETHING IS UP!
Yeah, but river warming is all due to people cutting down the trees that used to line the river banks.
Even the Gorebull warming nutballs own writings show the river warming is due to loss of tree cover.
“Deforestation also drives climate change. Forest soils are moist, but without protection from sun-blocking tree cover, they quickly dry out. Trees also help perpetuate the water cycle by returning water vapor to the atmosphere. Without trees to fill these roles, many former forest lands can quickly become barren deserts.
Removing trees deprives the forest of portions of its canopy, which blocks the sun’s rays during the day, and holds in heat at night. This disruption leads to more extreme temperature swings that can be harmful to plants and animals.”

>>OMG!!! Life is going to ADAPT (as it always has), and as will humans, likely better than ever before, because our knowledge-base, science and technology makes us better poised to adapt than ever before. Plants will shift, animals will shift, but abundant life, writ large, will continue.
LOL, funny how people who believe that evolution can turn an ape into a human can’t change a fish to live in water that is 2 degrees warmer.
I noticed the same thing. They believe in repeating the lie.
I have 2 or three weather apps and my own weather station, rarely are the temperatures within 10 degrees of each other.
Actually, my diabolical plan is to sell my home to one of these tree huggers at an obscenely inflated price and then get the heck out!
Whenever I need a weather forecast I ask a Hollyweird celebrity ;’}
Or are we still coming out of the little-ice-age? Such fuss over a trace gas that isn’t even the most influential greenhouse gas by a wide margin.
Ever increasing numbers of fishermen have a greater impact on fish and a 1.8 degree rise in temperature.
Yeah! I dare anyone to jump into either the Cle Elum, Yakima, Naches or the Columbia Rivers right now without a wet suit. Hypothermia.
“That’s the same rise measured at the Bonneville Dam over the last 80 years and used in models by climate scientists.”
Shove your “models”.
I quit Trout Unlimited a few years ago when they bought into this rubbish.
“If you live in Seattle, you better get out. Now!”
Shhh...we want them to be there when Mt. Ranier blows it’s cork and the molten lava finds it’s way to the sea via Seattle. Now that would be REAL global warming not the fake crap they worship.
Thats good.
No, no you don’t understand!! There will be no snow to melt!! Algore SAID the even the Arctic will be ice free by 2014..oh wait....
And, and the Himalayas will be free of snow by 2035....oops!
