Here are two summaries.
First, here is a link to a summary of 2008 Global Tropical Cyclone Season by Dr. Jeff Masters at Wunderground. The number of Atlantic hurricanes is often cited for support of global warming. But, it that is the case shouldn’t the cyclone number and strength be increasing everywhere? Another point of contention is how long have we been accurately recording tropical cyclone activity. Since the Caribbean Sea has been continuously sailed for several hundred years, some think we have accurate records there. In reality, many hurricanes could go completely undetected until satellites and aerial surveillance were available. Personally, I believe we only have a few decades of good information about North Atlantic tropical cyclone activity. For more information, here are the hurricane reviews(2008) and fore cast(2009) by Dr. Bill Gray’s group at Colorado State
