Short summary
Lakes in Greenland serve as a crucial sentinel of climate change. Satellites can be used to monitor water temperature and ice. Using 28 years of measurements from satellites, we conclude that lakes are overall warmer than previously thought. The lakes connected to the ice sheet are cooler than the rest because of cold glacial meltwater inflow. Changes in water temperature can impact light availability, nutrient cycling, and oxygen levels that are crucial for the lake ecosystem and have an influence on the ice sheet.
