Why can freshwater ecosystem regulate climate?

Freshwater ecosystems are reservoirs and freshwater lakes.

First, the adjustment of temperature: the specific heat capacity of lakes is greater than that of land, and the temperature rises slowly during the day, and the temperature is lower than that of land; The temperature drops slowly at night, and the temperature is higher than that on land. The temperature difference between day and night in the lake is small.

2. Adjustment of precipitation: Through evaporation, lakes make the water vapor content and cloud cover in the sky more, the precipitation increases, and the variability of precipitation decreases.
