From a NOAA press release..........
A scientific team has determined that economic damages from hurricanes have increased in the United States over time due to greater population, infrastructure and wealth on the U.S. coastlines and not because of any spike in the number and intensity of hurricanes.
My first thought when I read this yesterday was "no sh..!" but, it is still nice to see this type of report being released through NOAA. There is just way too much building going on along exposed, low-lying coastal areas in this country. You are just asking for trouble in my opinion.
According to Chris Landsea, operations officer at NOAA's National Hurricane Center, the economic costs of land-falling hurricanes have steadily increased over time, but there is nothing in the U.S. hurricane damge record that indicates global warming has caused a significant increase in destruction along our coasts. The report states that the economic damage from hurricanes is doubling every 10-15 years!
