Temperature decreases will affect the water cycle. Since the temperature is lower, less water will evaporate. Water has a specific boiling point at which it evaporates and if it is lower than that temperature, the water cannot evaporate. Colder air holds less water vapor, which leads to less rain and can cause droughts. This will throw the entire water cycle off balance.
