Bit of a gap in this thread from August 31, 2014 to Feb. 22, 2015 but can't recall this article from December, 2014 being chucked in here?
"D.C. has passed sea level rise 'tipping point,' more cities to follow: study"

SAN FRANCISCO — Major U.S. coastal cities, including Washington, D.C. and Wilmington, North Carolina, have already slipped past a sea level rise-related “tipping point,” and into a new era of increasingly common and damaging coastal flooding events, a new study found.
Other cities along the East and Gulf Coasts are following close behind, with the majority of coastal areas in the U.S. expected to see 30 or more days of “nuisance-level flooding” each year by 2050, regardless of how significantly countries cut emissions of the greenhouse gases that are causing global warming, according to the study.
The study defines this flood frequency as the "tipping point" in the local flood regime, with major implications for the management of coastal roads and critical infrastructure located close to sea level, since there will be far less time for repairs between floods.
Nuisance-type flooding is defined as flooding to a height of between 1 to 2 feet above local high-tide levels. Such floods, the study said, are now five to 10 times more likely today than they were just 50 years ago.
Although the term “nuisance floods” may connote minor flooding with little reason for concern, the impacts of repetitive floods should not be underestimated, the study’s lead author, William Sweet of the National Oceanic and Atmospheric Administration (NOAA), told reporters at the annual meeting of the American Geophysical Union on Thursday.
“It’s an emerging flooding crisis,” Sweet, an oceanographer with NOAA’s National Ocean Service, said.
The new research, published in the open-access journal Earth’s Future, is among the first to look at the rapidly changing frequency of minor coastal flooding in response to sea level rise.
Extremes are rising far faster than the mean
