NewsClimate change is increasing risk of high toxin concentrations in Northern US lakes
As climate change warms the Earth, higher-latitude regions will be at greater risk for toxins produced by algal blooms, with water temperatures of 20 to 25 degrees Celsius at greatest risk for developing dangerous levels of a common algae-produced toxin.
