U of M researchers find as planet warms, the world's lakes are losing oxygen rapidly

Oxygen levels in the world’s temperate freshwater lakes are declining at rates faster than in the oceans, according to new research from the University of Minnesota and Rensselaer Polytechnic Institute. It’s a trend researchers found is largely driven by climate change and land use, threatening freshwater biodiversity and the quality of drinking water.
