I am bemused by the predictions that global warming will make the global climate drier. It is well known that the climate during glacials was cold and dry. During interglacials (like now) the climate is warm and wet. The mechanism is pretty simple. Hotter winds blowing over warmer oceans cause more evaporation, and what goes up will come down. That is a vast simplification (and, yes, some places were wetter when the climate was cooler) but it should hold true at the global scale.
Can anyone comment on whether the climate change models really do predict a global drying, or is it just a common misconception? If they do predict a general drying by what mechanism is that supposed to be achieved?
