Sandbagged, trashed beach at South Nags Head, N.C. in February 1987, with some evidence of bags that have been torn or ruptured and have leaked sand. The scarp under the houses indicates that storm waves are topping the bags, and buildings were damaged or lost in the end. Captions and Photo courtesy of: © Orrin Pilkey.

Excerpts;

Sea level rise driven by climate change is set to pose an existential crisis to many US coastal communities, with new research finding that as many as 311,000 homes face being flooded every two weeks within the next 30 years.

The swelling oceans are forecast repeatedly to soak coastal residences collectively worth $120bn by 2045 if greenhouse gas emissions are not severely curtailed, experts warn….

Coastal communities saw record number of high tide flooding days last year; NOAA (06-06-2018)
People living on the coast may see flooded sidewalks and streets more frequently this year due, in part, to El Nino conditions that are predicted to develop later this year, and from long-term sea level rise trends…

Patterns and projections of high tide flooding along the US coastline using common impact threshold; NOAA (February-2018)
For forecasting purposes to ensure public safety, NOAA has established three coastal flood severity thresholds. The thresholds are based upon water level heights empirically calibrated to NOAA tide gauge measurements from years of impact monitoring by its Weather Forecast Offices (WFO) and emergency managers…

New Study Finds Sea Level Rise Accelerating; NASA (02-13-2018)
Global sea level rise is accelerating incrementally over time rather than increasing at a steady rate, as previously thought, according to a new study based on 25 years of NASA and European satellite data…

In Next Decades, Frequency of Coastal Flooding Will Double Globally; USGS (05-18-2017)
The frequency and severity of coastal flooding throughout the world will increase rapidly and eventually double in frequency over the coming decades even with only moderate amounts of sea level rise, according to a new study released in “Scientific Reports.”…

The next five years will shape sea level rise for the next 300, study says; The Washington Post (02-20-2018)
Peaking global carbon dioxide emissions as soon as possible is crucial for limiting the risks of sea-level rise, even if global warming is limited to well below 2 degrees C. A new study analyzes for the first time the sea-level legacy until 2300 within the constraints of the Paris Agreement…

Sea Level Rise Will Reshape U.S. Population In All 50 States; Yale E360 (04-19-2017)
Sea level rise could cause mass migrations that will affect not just the United States’ East Coast, but reshape communities deep in the heart of the country, according to new research…

How rising seas and coastal storms drowned the U.S. flood insurance program, Yale E360 (04-19-2017)
Sea level rise and more severe storms are overwhelming U.S. coastal communities, causing billions of dollars in damage and essentially bankrupting the federal flood insurance program. Yet rebuilding continues, despite warnings that far more properties will soon be underwater…
