"One of the most serious consequences of global warming is its predicted impact on the water cycle. A new study, described below, presents evidence that the global water cycle is changing even faster than predicted."
Global warming is affecting the salinity of ocean water. This is creating a nightmare among places that depend on a constant flow of rain. Because of the complexity of Global Warming it is assumed that some areas will become wetter, some will become drier. It's the places inbetween that might see the most volatile of weather. Floods one year, droughts the next, trying to predict what will occur on a routine basis is now nearly impossible by just looking at historical records.
