Acidic oceans, warming rivers devastate salmon runs

What’s the way forward for the Columbia River and its salmon? Look to 2015.

That 12 months’s extraordinary mixture of overheated river water and low flows killed a whole lot of hundreds of returning sockeye salmon, devastating a run that had rebounded from near-extinction.

Thousands and thousands of recent sockeye and steelhead smolts migrating the other means, to the Pacific, died all through the river system; solely 157 endangered sockeye made it again to the Sawtooth Valley this 12 months.

By the center of this century, scientists counsel, the temperatures we noticed in 2015 would be the norm. The low snowpack and streamflows have been examples of what the Pacific Northwest ought to anticipate on the finish of this century on account of fast local weather change brought on by the burning of fossil fuels, climatologists say.
