Three Cape Verde hurricanes have formed at the same time in the south central Atlantic while a fourth storm in the Pacific in threatening Hawaii with it’s second hurricane of the season. At the same time, a new tropical depression is forming south of Florida. As the oceans warm, generalized outbreaks such as this will become the new normal, and coastal areas from Florida to Newfoundland will experience high-category named storms on a regular basis. In additon, warming Pacific waters will enable storms that form off the Baja Peninsula to move up into southern California waters within a few years.

It mightn’t be quite a case of the flapping of a Brazilian butterfly’s wings causing a tornado in Texas, but a team of climate researchers has found a correlation between melting Arctic sea ice and the formation of tornadoes in the United States, with fewer tornadoes being reported when northern sea ice is unseasonably low.

"A relationship between Arctic sea ice and tornadoes in the US may seem unlikely," says study co-author Jeff Trapp, an atmospheric sciences researcher with the University of Illinois at Urbana. "But it is hard to ignore the mounting evidence in support of the connection."
