Date Time Climate change: Worldwide emergence of dead zones in lakes As climate change progresses, lakes also warm up, the oxygen concentration in the water decreases and dead zones in deep zones develop. Ruben Sommaruga from the Institute of Ecologyand an international team of researchers were the first to identify this dramatic widespread development in a study of 393 lakes around the world. The results were published in the journal Nature. The temperature in lakes is also subject to the continuous warming of the climate. As water temperature increases, gas diffusion at the surface of lakes decreases and thus, the oxygen concentration in the lake decreases as well. Ruben Sommaruga and more than 40 scientists from all over the world studied the oxygen concentration in relation to temperature in 393 lakes over a period of more than 70 years. A total of 45,000 combined profiles of temperature and oxygen were analyzed. This close collaboration was made possible by the Global Lake Ec
