Researchers are studying the impact of global warming on lakes, where heatwaves in sediment are occurring. Climate change is projected to intensify issues such as lake anoxia, deoxygenation, and eutrophication, potentially altering the balance of freshwater ecosystems. The effects of these heatwaves on lake ecosystems are being investigated, including changes to phytoplankton and zooplankton communities and the growth of harmful algae.
