description: After major hurricanes Harvey and Irma made landfall in the United States in 2017 and as Hurricane Florence approaches the Carolinas in 2018 there have been renewed calls to do something about global warming. The popular perception that landfalling hurricanes in the U.S. are becoming more frequent or more severe however is shown to be incorrect. The 30 costliest hurricanes in U.S. history have indeed become more expensive in recent decades but it is demonstrated that as damages have increased hurricane intensity has not. The cause of increasing damages is increasing population and infrastructure in hurricane-prone areas. History has demonstrated that major hurricanes sometimes arriving in pairs have been part of Atlantic and Gulf coastal life for centuries. Even lake bottom sediments in Texas and Florida reveal more catastrophic hurricane landfalls 1000 to 2000 years ago than have happened more recently. Over the last 150 years the number of major hurricanes hitting Texas has been the same when Gulf of Mexico water temperatures were below normal as when they were above normal. Harvey's record-setting rainfall totals were due to its slow movement which cannot be traced to global warming (August 2017 was quite cool over most of the U.S.) combined with substantial land subsidence preventing rivers from draining more rapidly to the ocean. Major hurricane strikes in Florida since 1900 have if anything become somewhat less frequent and less severe. What has changed in Florida again is coastal development. The Miami - Fort Lauderdale metroplex now has a population of over 6 million whereas a little over 100 years ago it was nearly zero. As a result our vulnerability to major hurricane strikes has increased dramatically. Even with no change in hurricane activity hurricane damages will continue to increase along with wealth and infrastructure in coastal areas. It is only a matter of time before our first trillion-dollar hurricane catastrophe occurs and it will happen with our without carbon dioxide emissions from fossil fuel use.
