Information about Sea Level Rise on the East Coast of the United States comes from a credible publication from Yale University By Jim Morrison • April 24, 2018 /Yale Environment 360/Flooding Hot Spots: Why Seas Are Rising Faster on the U.S. East Coast

From 2011 to 2015, sea levels rose up to 5 inches in some locales from North Carolina to Florida. What Norfolk gets is that while sea level is rising globally at about a tenth of an inch per year, cities along the Eastern Seaboard of the United States — including Norfolk; Baltimore; Charleston, South Carolina; and Miami, among others — have suffered “sunny day” flooding from seas rising far faster than the global average. One study published last year shows that from 2011 to 2015, sea level rose up to 5 inches — an inch per year — in some locales from North Carolina to Florida. Given growing concerns over the flooding, scientists are now working to unravel the mystery of why some parts of the globe are experiencing so-called “sunny day” flooding that had not been expected for decades under conventional sea level rise projections.

Along the southeastern coast of the U. S Along the southeastern coast of the U.S., researchers have zeroed in on three factors that have made this shoreline a regional hot spot of sea level rise. They include a slowing Gulf Stream, shifts in a major North Atlantic weather pattern, and the effects of El Niño climate cycles. Scientists from the National Center for Atmospheric Research (NCAR), for example, have found that sea levels in the northern Indian Ocean are rising more rapidly than the global average and threatening densely populated shores, particularly along the coastlines of the Bay of Bengal, the Arabian Sea, Sri Lanka, and Sumatra. Scientists say that shifting monsoon patterns have significantly warmed the north Indian Ocean, causing unusually rapid thermal expansion of the region’s seawater and thereby increasing sea levels.

In a paper published earlier this year, those NCAR scientists modeled sea level rise for 20 cities worldwide. They found that cities like Boston and New York might experience twice the global mean increase, while San Francisco and Buenos Aires will likely be 15 to 25 percent below the mean.

Sunny day flooding and King tides what one researcher calls “high tide on steroids” — has increasingly disrupted coastal cities in the southeastern U.S. coast. In Charleston, tidal flooding increased to 50 days in 2016, up from four days annually 50 years ago, causing millions of dollars in damage and disrupting travel to the city’s hospital district. In Miami, flooding during unusually high tides, what local forecasters call “king tides,” is becoming an increasingly severe problem, with clear-weather flooding accelerating to nearly 20 days a year. But much worse is to come.
