Hurricanes have been menacing the U.S. as long as anyone can remember, but the monetary damages the storms have caused has increased in recent years, as this TIME photo collection shows. The devastation from Hurricane Sandy — later dubbed a “Superstorm” — rang in at $65 billion, leaving 72 people dead and more than 6 million homeless.
Does that mean hurricanes are getting more powerful or more common? Not necessarily. While many atmospheric scientists believe that climate change may strengthen tropical cyclones—higher temperatures at the ocean tend to feed hurricanes—the power of the storm isn’t the only factor in the extent of the damage. Far more important, at least for now, is the increase in the number of people and the value of the property in coastal areas that are perennially vulnerable to major hurricanes. Hurricane Katrina was so expensive not just because it was powerful, but because it landed directly on top of a major American city—and one that was clearly unprepared for a storm of that magnitude.
The more people and property we put in harm’s way, the greater thee damage any storm will cause. If climate change really does give hurricanes an extra kick—and if we do nothing to slow global warming or prepare for the effects—damage will be incalculably greater.
