I agree with the following information:
From the site:
http://www.voanews.com/english/2005-09-20-voa49.cfm
"Thirty-five years ago, major hurricanes made up about one-sixth of all tropical storms. In recent years, that percentage has risen to one-third. During that same time, water surface temperatures around the world have also grown warmer. The warmer water evaporates at a quicker rate, and once it rises into the atmosphere, the condensation releases energy that forms the storm.""
What I do not agree with, is the explanation of why the water surface temperatures around the world have grown warmer.
