Fast Company: These maps show how many days a year your coastal city could flood. By 2050, some coastal cities could have flooding every day of the year. High tides, caused by the effects of the sun’s and moon’s gravitational pulls on the Earth, are no new phenomenon. But coastal flooding from such high tides is becoming more and more of a problem. As global warming worsens and sea levels rise, high-tide flooding is affecting coastal communities more than ever before.
A new website shows users, via multiple maps of the U.S., the estimated number of days of high-tide flooding that could occur per year up to 2100. As someone looks at the maps, they can drag a bar to change the year, in one-year increments, and observe the severity of flooding in 99 different coastal cities across the country. Different colors represent greater danger, and users can zoom in and click on a specific city to see the number of flooding days there.
