Excerpt: In 19 years of piloting his boat around Lake Superior, Jody Estain had never observed the water change as it has this summer. The lake has been unusually balmy and cloudy, with thick mats of algae blanketing the shoreline. “I have never seen it that warm,” said Mr. Estain, a former Coast Guard member who guides fishing, cave and kayak tours year-round. “Everybody was talking about it.” ...Scientists generally agree that algae blooms are getting worse and more widespread, and are exacerbated by the warmer water, heat waves and extreme weather associated with climate change. They are also intensified by human activity, such as from farm and phosphorus runoff, leakage from sewer systems, and other pollution. The problems that algae blooms pose to fresh and marine waters have been propelled to the forefront in recent years by high-profile events like the shutdown of the water supply in Toledo, Ohio, in 2014 after toxic algae formed over the city’s water-intake pipe in Lake Erie, as well as the production of a toxin by a species of algae off the West Coast in 2015....
