Sea Level Rise

Accelerated erosion

View Sea Level Rise Gallery

There will always be beaches, but sea level rise will ensure that they will not be in the same place in the future. The beaches will still exist throughout this change, but many of the buildings may not. Efforts to save development, however do threaten beaches, such as shoreline armoring structures.

Although relative amounts of rise may seem very small, only a few millimeters per year, the cumulative effect of these small rises each year over a long period of time (100+ years) causes major problems. Accelerated rates of erosion are attributed to sea level rise and erosion causes large economic losses around the world each year due to the close proximity of buildings and critical infrastructure. This includes transportation systems, gas and oil lines as well as electricity lines and power plants.

Most developed coasts and beaches have buildings very close to the ocean leaving little room for the ever-expanding ocean. The future effects of sea level rise on coastal civilization over the entire world are of great concern. Over half of the world’s population lives within 100 km of the coast. Over the next 50 years, damage due to coastal development will be devastating, but if the rate of sea level rise increases, the results could be catastrophic. This issue threatens areas from New York City in the United States to the Pearl River Delta in China to the Maldives.

The world map below allows you to see elevations of coastal areas. Areas in red are the lowest in elevation and are most prone to flooding. Check out Manhattan in New York City. If you think the situation there looks dire, be sure to check out the effects of a 2 m rise in sea level on Pearl River Delta in China, home to more than 40 million people.

‘King tides’ are rising, so groups span globe to monitor it

From coast to coast, hundreds of tide watchers come out with their cameras to record the latest ‘king tides,’ brief episodes of tidal flooding that could become the norm, with expected sea-level rise.

Rising waters: can a massive barrier save Venice from drowning?

A retractable barrier designed to protect Venice from sea level rise and storm surges is set to be operational next year. But the project’s engineering limitations and cost overruns are raising questions about the mega-projects that many coastal cities are hoping can save them.

Buried in marshes’: sea-level rise could destroy historic sites on US east coast

Large tracts of America’s east coast heritage are at risk from being wiped out by sea level rise, with the rising oceans set to threaten more than 13,000 archaeological and historic sites, according to new research.

Coastal Commission Rejects Bid to Cancel Broad Beach Sand Replacement Permit

One of the line-items on the November 2017 California Coastal Commission agenda was a one-year extension of the beleaguered Broad Beach Replenishment Project. Following years of delays with issues ranging from sand sourcing to legal battles of all shapes and sizes, the project has been slow to get off the ground, and proponents of alternatives such as artificial reefs are hoping to succeed.

On N.H.’s Coast, Preparing for Future Storms with Grass, Sand and a Bit of Time

As New Hampshire’s coastline prepares for a world with rising seas and stronger storms, communities and homeowners have different options, none of them simple. But some scientists in New Hampshire are pitching a more natural approach. All it takes is a little grass and some time.

South Carolina not doing enough to protect beaches, report says

South Carolina’s beach preparations are barely adequate to deal with worsening erosion, sea rise and intensifying storms, according to the latest Surfriders Foundation report.

Study: NC gets ‘D’ for climate change policies

Days after a federal report issued a harsh warning about climate change, an environmental group said North Carolina’s policies leave the state among the most ill-prepared on the East Coast to deal with the effects of rising seas.
