Anyone who takes fly-fishing seriously behaves like a scientist. These anglers are biologists, knowledgeable in what’s eating what, when and how. They are hydrologists, studying riffles and stream flow. They are naturalists, observing clouds and sunlight and the circulation of air as their rods flick back and forth across the big sky. They are, in a sense, climate scientists. And some, but not all, are deeply concerned about the effects of a warming climate on the cold-water species that inhabit blue-ribbon trout streams.

Here in Montana, with pristine rivers that are home to some of the best fly-fishing in the country, a majority of votes went for President Trump—and climate change is considered by many of them to be a natural phenomenon beyond human control.
