The greenhouse effect is accelerating the global water cycle almost twice the rate predicted by climate change models.

Global climate models predict that as the globe warms, this will heat the lower atmosphere and enable it to hold more moisture, thus speeding up the global water cycle. This is like the rich getting richer while the poor is getting poorer, but with dry and wet areas.

Global warming increases salinity too, because the more rain that falls in the oceans, the more freshwater dilutes out salinity, the more evaporation there is, the higher the ocean’s salinity.
