In addition to an increase in earthquake and volcanic activity, as has recently been seen in and around the Pacific ring, with global warming there also comes an increase in storm activity.

With the exception of 1997 and 2002, every year since 1995 has had an above average hurricane activity. The intensity of them has also increased, with a higher percentage of category 4 and 5 hurricanes. In August 2005, hurricane 'Katrina' hit New Orleans and became one of the worst disasters the United States had seen since the Great Depression. In September, 'Rita' became the most intense tropical cyclone ever recorded in the Gulf of Mexico and in October 'Wilma' became the most intense hurricane ever recorded in the Atlantic basin.

( Hurricanes are also called Typhoons in the North West Pacific, and Cyclones elsewhere )
