Sadly, I think Venice will be gone first - the recent signs were ominous - with about 80% of the city under water.
The authorities had just curtailed the intrusion of cruise liners into Venice, where just 50,000 live. 36 million visit, annually.
I've been there a few times, always frequenting Harry's Bar for a Bellini. Also a bolt hole for Hemingway, Orson Wells and Charlie Chaplin.
Last time I was there - a few years ago - I noticed a famous red face. That of Michael Winner.
