Climate change will increase water temperatures and decrease dissolved oxygen levels , impacting freshwater fisheries which form an important ecosystem service . People living in the vicinity of cold lakes will be affected by projected losses of ice. In a worst-case scenario , 230,400 lakes and 656 million people in 50 countries will be impacted . Winter ice-fishing , transportation via ice roads  and cultural activities  are ecosystem services at stake from the ongoing loss of lake ice.
