However, there is no change in the long term weather patterns or climate. That has a number of reasons. Rain is not just over-saturated air out of which the water falls just like that. The process that leads to rain is fantastically complicated geochemistry. It can happen that you get 100% humidity but still: no rain. When the temperature drops you only get over saturated air and fog, yet still: no rain. And even if enough surface water is available, nothing happens. Only the evaporation stops.
