There is some new research about the effects of GW on sea temperatures
in sea areas where tropical cyclones form. It was published this month
and is reported in The Independent today. Quote:

"The American-based team, whose work is reported in the US journal
Proceedings of the National Academy of Sciences, used 22 different
computer climate models to look at the warming of oceans during the
20th century, which in the hurricane breeding grounds of the tropics
range from 0.32C to 0.67C. Unlike previous investigations, the new
research has focused on small cyclone- forming regions rather than
entire ocean basins.

"The important conclusion is that the observed SST increases in these
hurricane breeding grounds cannot be explained by natural processes
alone," said one of the scientists involved, Dr Tom Wigley, from the
National Centre for Atmospheric Research in Boulder, Colorado. "The
best explanation for these changes has to include a large human
influence."
