From these two graphs we have drawn the following conclusions: precipitation in the last 20 years has varied with an upward trend, which coincides with another increase in temperatures, this causes more water to evaporate, and as it circulates and has Sierra Nevada next to it, it rises and cools, which produces precipitation. This precipitation will end up in the lagoon again, because the plates are below each other. This does not in itself affect the surface, as although there is more precipitation there is also more evaporation of water so it balances out, but it does affect the species.
