Experts say Mediterranean growing more dangerous for yachting, often critical situations with little warning

Climatologists say global warming is making such violent and unexpected tempests more frequent in a sea used as a summer playground for millions of tourists, including a wealthy few sailing its waters on superyachts.

Luca Mercalli, president of Italy's meteorological society, said the sea surface temperature around Sicily in the days leading up to the shipwreck was about 30 degrees Celsius (86 degrees Fahrenheit), almost three degrees more than normal.

"This creates an enormous source of energy that contributes to these storms," he said. The changes in "Mare Nostrum" (Our Sea), as the ancient Romans called the Mediterranean, are also being noticed by experienced skippers such as Massimo Aramu, who runs the Akua sailing school on the coast near the Italian capital.

Aramu said he did not like navigating Italy's Tyrrhenian coast around Sicily or the Balearic islands because there are "often critical situations with little warning".

In August a storm similar to the one that sank the Bayesian hit the Balearics, leaving several yachts washed up ashore. Giuliano Gallo, a former skipper who crossed the Atlantic and has written several books on sailing, said the Mediterranean was becoming more like the Caribbean, which has areas that many boats steer clear of at certain times of the year.

"But things are less predictable in the Mediterranean," he said.
