NOAA Study: We Can Expect High-Tide Flooding Every Other Day By 2100 Along E. Coast, Gulf Of Mexico
And that's the best-case scenario.
High-tide flooding, which can wash water over roads and inundate homes and businesses, is an event that happens once in a great while in coastal areas. But its frequency has rapidly increased in recent years because of sea-level rise. Not just during storms but increasingly on sunny days, too.
Years ago, the late Margaret Davidson, a coastal programs director at the National Oceanic and Atmospheric Administration, warned it wouldnt be long until such flooding became routine. Todays flood will become tomorrows high tide, she said. A new NOAA report has published startling new projections that affirm Davidsons warning.
By 2100, the report says, high tide flooding will occur every other day (182 days/year) or more often even under an intermediate low scenario in coastal areas along the East Coast and Gulf of Mexico. This scenario works under the assumption that greenhouse gas emissions which warm the climate and speed up sea-level rise are curbed.
For a more aggressive intermediate scenario, in which greenhouse gas emissions carry on at todays pace, high-tide flooding is forecast to occur 365 days per year.
