Not that the charts below show anything meaningful at all, but just interesting to note that, no sooner has a study been done to show than humans are affecting rainfall patterns (first link) than we get some of the worst rains in memory in Africa (second link). Except that the rains are occuring where the study predicted less precipitation - not more.
