Global warming is increasing the temperatures of lakes worldwide—are species finding the temperatures they need to survive? Researchers led by scientists at the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) have quantified the long-term temperature changes in 139 lakes worldwide. Those lakes represent about 69% of the Earth’s freshwater habitats by volume. The researchers analyzed shifts in thermal habitats—the temperature conditions needed by species to survive. They found that as lakes warm, species will need to shift to different depths or seasons to find suitable thermal habitat. But not all species will be able to shift. The study was published today in Nature Climate Change.
