ConclusionsConclusions

If the patterns of the previous years If the patterns of the previous years continue Southern California will see continue Southern California will see more artificial seasons and this on its more artificial seasons and this on its own will contribute to the shortening own will contribute to the shortening supply of fresh water available for supply of fresh water available for the future.
