It has been raining and pouring, and this year's rain has been one for the record books, at least in Philadelphia. Read the great posting at http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=2001. The rain total in Philadelphia has exceeded 62 inches, breaking a record set in 1867. Average annual rain fall in Philadelphia is 40 inches.
Jeff Masters calculated that 56% of the USA has either experienced extreme drought or extreme rain in 2011.
Global warming scientists have stated that dry areas will likely get drier and wet areas wetter, as a warming climate impacts evaporation and precipitation.
