When I was growing up summer seemed to last forever, and when we had to go back to school at the end of August we sometimes would take our "classroom" outside because it was stifling inside the building even with the windows open and some fans going.  The climate has changed all right but I went to school 50 odd years ago so I would think it would change in some ways, even though I'm not a believer in the greenie movement - those people don't know siccum.
