The men and women who fish commercially off the shores of the United States have long battled the ocean, unexpected storms and the fickle nature of a quarry that can simply swim away. But scientists say climate change is rapidly complicating those existing challenges. It helps supercharge storms, heats the water, kills some species and prompts others to flee to colder waters. USA TODAY, with support from the @PulitzerCenter, brings you the stories of four fishers from around the United States. Each is seeing the impacts of climate change on an industry already struggling with the high cost of diesel fuel and the wildly fluctuating prices they get for their catch. 📸: @yannick_peterhans @megankristin @photojmorgan @jaspercolt
