Freshwater lakes have been identified as a potential “ticking time bomb” amid fears greenhouse gases contained in the water could double as a result of climate change, scientists have warned. A University of Cambridge study found that after adding to the amount of plant matter in the water, a consequence of warmer temperatures, the amount of methane and carbon dioxide increases by an average of 1.5 to 2.7 times. The findings, published today in the Proceedings of the National Academy of Sciences of the United States of America (PNAS), simulated the effects of climate change on freshwater lakes in Ontario in Canada. Dr Andrew J Tanentzap, Head of Ecosystems and Global Change at the University of Cambridge said that this study demonstrated the “ticking time bomb” of delicate ecosystems found in freshwater lakes.
