cloudy days

Just what are so many days cloudy and so few are sunny? Not sure we got an answer. Blame global warming. Except, scientist say global warming increases rain - wrong. They claim it turns earth into a dry desert where every day is sunny. However, our planet is 70% cover over in water so that means more rain. OK, so warm weather mean more evaporation and more rain or snow.  Still, this does puzzle us. It is an enigma.
