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.

These rivers are snow melt. Please explain.
The warming of the ground is precursor to the pyroclastic flows that will destroy Seattle. If you live in Seattle, you better get out. Now!
These rivers are snow melt. Please explain.
“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.”
Yeah, and ALL of the river warming is due cutting the trees that used to shade the banks!
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.
Ice cube machines along the banks. End of problem.
Is it my imagination or are hysterical global warming stories now being produced at an unprecedented feverish pace. You would think the world would have fatigued at cry wolfism decades ago when nothing ever happens, unfortunately the entire media now hypes each and every average storm to hyperbolic dimensions so the drones think the whole world is in a perpetual state of deterioration.
Over the years have scene many states impose fishing licenses on beach fishing into the ocean. The states have absolutely no control over migratory fish species that passed through areas offshore and into the areas where fishing off of beaches and Piers takes place.
So, it’s not a naturally occurring diminishment of fishing in my area it’s a state-imposed impediment to reduce my fishing time should I choose to purchase a fishing license to fish in saltwater which up until 10 years or so back my fist anywhere I wanted to install water and it was free. I don’t understand what changed other than greed.
the Cascadia tectonic plate related tsunami is due every 300 years the last one was in 1700 on January 27th. Documented through tree-ring analysis and writings in Japan which the tsunami eventually hit a couple of days after the event. It’s online there’s lots of information lots of geologic study and the concurrence is that every 300 years for the last 10,000 years there has been this subduction plate snapback. Standby.
Fair enough. 1.8 degrees over 80 years. Let's see the raw data. Is it "modeled", or has it been "adjusted"? Or, was it cherry-picked to hit a starting low point 80 years ago?
Sad that these questions need to be asked of researchers, and sadder still that "journalists" won't bother to ask.
Which is better...to get 2 degrees warmer climate to conserve modern civilization or go back to living like people did 100 years ago with no cars, no airplanes and travel by horse and buggy? All in the name of preserving river fish?
Besides I prefer taking my shirt off when it is off over freezing my butt in cold weather.
Have you also noticed that every storm now gets a name? I guess that makes it more “personal”, like it’s affecting you directly.
I call them “climate scientologists”.
Dollar to donuts thee is no temperature readings taken. Some idiot is just guessing in a fantasy about global warming.
That’s nothing - my pool has risen 218 degrees C over the last hundred years. Any my house was built in the 90’s. And I don’t have a pool. But it’s science......
Given that global temps have risen around .2 degrees C over the last 100 years - how do the rivers have a delta an order of magnitude higher. Just lol.
This is what you call - fake science.
Elections are coming. Left needs an issue.
1976 is when “scientists” thought we were entering a mini ice age. Any temperature data with mid 70’s as a starting point is biased. Somehow when we hit a record high it breaks a record from a long time ago, like from the 1930’s. Then there are all the eons that the earth has been here before that.....
“It’s in the latter half of the century that we have more uncertainty.”
More like in the latter half of this year. Their projections are completely useless. Do they ever show their accuracy in projections?
Beat me to it, Didn’t it snow out west a week ago including Arizona. The upper tier has been unusually cold this sprig and there’s still snow in my yard, I call B.S.
