“When you spend a lot of time outdoors, and you do it over decades, you start to see a pattern, and you can count on those things happening over and over again at approximately the same time (of year),” said Todd Tanner, a Montana resident who has been fishing for more than 55 years. “Anyone who has been fly fishing for a decade or longer has seen the impacts of climate on our fisheries.”

They see warmer temperatures, heavier rains and natural events that have become more unpredictable, if they happen at all, said Tanner, founder of Conservation Hawks, a group seeking action on climate change to preserve hunting and fishing.
