Too Hot Already!!!

The 3rd of June & it is already in the 80's headed for the 90's. I don't know why I am surprised because we had some hot, hot days back in what is officially called winter.
Global warming?? Definitely. Last Monday driving from Missouri to Tennessee, using the handy, dandy on-board therometer, I watched the temp. go from the 80's in the developed areas down to the low to mid 70's in the rural areas. As soon as we got close to Nashville where the trees, grass, & other vegetation have been replaced with cement & blacktop right back into the 80's we went. With in a few miles.
Come on, why do we have to have hundreds of buildings and parking lots being built while we have plenty of empty buildings & unused parking lots right next to the new construction??? If you don't like the layout why not tear those down & rebuild on that site instead of destroying the green that remains?
