Dozens of researchers pooled decades’ worth of data from hundreds of lakes and concluded that the world’s lakes are warming even more rapidly than the oceans or the atmosphere. The warmer waters threaten fish populations, ecosystems and fresh water supplies around the globe.
Closer to home, University of Minnesota Duluth Professor Jay Austin says the thick sheets of ice that blanketed Lake Superior for the past two winters did nothing to change the fact that Superior, like the other Great Lakes, is growing ever warmer.
“Lake Superior is one of the more rapidly warming lakes” among the 235 lakes in the study, Austin said. A two-degree temperature shift can mean the difference between an iced-over Superior or an ice-free Continue reading “Superior is one of the more rapidly warming lakes, study finds”
