New Report out LINK
The US coast from Cape Hatteras to New England is experiencing increased coastal or tidal flooding because of local sea level rise. I started this blog to track the developing scientific understanding of the causes and to provide sources of information to both scientists and anyone else interested.

Swiss Re report on the "Big One"
Swiss Re has a new report out on what the effect the the 1821 hurricane occurred now. LINK
Quoted from Swiss Re
Quoted from Swiss Re
It has happened before
Nearly 200 years ago a major hurricane pummeled the entire Mid-Atlantic and Northeast - from Norfolk to Washington, DC to Boston. The 1821 Norfolk and Long Island hurricane made landfall on the coast of North Carolina with wind gusts above 156 mph and carved a path of devastation up and down the Eastern Seaboard, making subsequent landfalls in Delaware, New Jersey and New York. Only 136,000 people lived in New York City and Washington at the time and losses were modest by today’s standards. There was no such thing as radar, satellites or the National Weather Service, yet there were many vivid accounts and records, which can be extrapolated to the present to create instructive assumptions.
Past plus present equals future
A new report from Swiss Re, The big one: The East Coast's USD 100 billion event (PDF, 730 KB) examines how the 1821 hurricane would impact the region today. Trillions of dollars of assets and infrastructure would lie in the storm’s path, much of it aging and along the coast. Using our in-house, proprietary tropical cyclone model we reconstructed the storm track, wind field and potential storm surge and concluded that a large area of the most heavily developed Eastern Seaboard would be exposed to hurricane force wind gusts.
Storm surge comparable to Sandy would inundate New York City, accompanied by powerful winds gusting over 100 mph. Norfolk, Virginia - home of critical US Navy installations - would be completely flooded. Coastal counties would sustain wind damage alone in excess of USD 1 billion. Combined physical damage from both storm surge and wind would exceed USD 100 billion, while the storm's total potential economic impact is on the order of USD 150 billion.
Hurricane Sandy was a wake-up call; if left unheeded, the 1821 Norfolk and Long Island hurricane would be the nightmare.

NOAA Tidal Datums
Michael
Michalski at NOAA/NOS provided links to several technical reports related to
datums.
Technical
report on the computation of the Modified Procedure for Tidal Datum Computation
which looks at the shorter 5 year period for areas of rapid relative sea-level
change.

Some additional references for tidal datum computation and datum error are the following.

The Ed Show
The Ed Show on MSNBC had a series on 'Rising Tide - the climate crisis'
In my opinion this is one of the best series I've seen.
Five 5 minute episodes
Not that easy finding stuff on the site but here are the titles and links. There was a fifth I think but cannot find it.
"Rising sea levels threaten major cities" LINK
"Rising tide a national security threat" - LINK - features many of us in the region.
"Hoboken pushes forward" LINK
"GOP Lawmakers ignore climate science" LINK
