The Journal Nature published an article entitled “Attack of the extreme floods: As the oceans rise, researchers aim to forecast where severe storms will trigger the worst flooding.”
“the height of what constitutes a 50-year flood event has risen by more than 10 centimeters per decade in some places”
“A rule of thumb holds that the frequency of events can be extrapolated up to four times as far into the future as the observational record reaches backward. A few decades of data won’t be sufficient to inform forecasts for a 10,000-year flood event, as is required for some communities and for sensitive infrastructure such as nuclear power plants.”
“[Re: Boston] what was a 100-year event in the 1820s is now more like an 8-year event”
“the coasts of the contiguous United States will fare differently. In eastern cities such as New York City and Charleston, South Carolina, it is the nuisance flooding that will become more frequent. By contrast, western cities such as Seattle in Washington, and San Diego in California, should expect more-frequent flooding from extreme events.”
