 This is CBS Eye on the World. I'm John Batchelor, welcoming Lorenzo Fiora of the Ansaldo Foundation in Milan. We go to a warning for everyone in Italy, even the healthy, of extreme temperatures. I'm looking at 17 major cities warned, including Florence, Bologna, and Rome. Lorenzo, a heat wave. It's summertime. Is this unusual heat? How is it in the north in Milan? Good day to you.
