water quality and productivity of algae, invertebrates and fish . In deeper lakes, warmer surface waters and decreasing wind speeds reduced shallow waters mixing with nutrient-rich deeper waters, reducing biological productivity in the upper sunlit zone . In several lakes, climate change was identified as causing changes in insect emergence time  and in loss of fish habitats . This set of changes can harm human livelihoods, for example, from reduced fisheries productivity  and reduced water supply and quality .
