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.

Sea level rise is already eroding home values, unbeknownst to their owners

Three studies have found evidence that the threat of higher seas is also undermining coastal property values, as home buyers – particularly investors – begin the retreat to higher ground.

Why sea level rise varies from place to place

In the 20th century, ocean levels rose by a global average of about 14 centimeters, mainly due to melting ice and warming waters. Some coastal areas saw more sea level rise than others. Here’s why.

Rising sea levels threatens coastal cities with more tsunamis, scientists warn

Tsunamis will become more common and more ferocious with global warming, scientists have warned after a study found that global sea level rises will increase the risk of coastal cities being wiped out.

Cost of Coastal Flooding in Europe Could Reach $1 Trillion Annually by 2100

Without additional climate change adaptation measures, the annual cost of damage from coastal flooding in Europe could jump from $1.4 billion today to as much as $1 trillion by the end of the century due largely to rising sea levels according to new study.

Sea level rise has already sunk Carolinas beach property values — by $1.6 billion, study finds

Sea levels are rising and the southeast has already lost billions in property value, a recent study shows. Scientists have found $7.4 billion was lost in home values across North Carolina, South Carolina, Virginia, Georgia and Florida because of sea level rise flooding from 2005 to 2017.

Study Finds Link Between River Outflow and Coastal Sea Level

Sea levels in coastal areas can be affected by a number of factors: tides, winds, waves, and even barometric pressure all play a role in the ebb and flow of the ocean. For the first time, however, a new study has shown that river outflow could play a role in sea level change as well.

Coastal homes could see flood insurance premium going up again, and that’s only the beginning

FEMA is looking into switching to risk-based pricing in 2020, which would end the subsidies most coastal communities enjoy on their flood insurance premiums and show the true dollar cost of living in areas repeatedly pounded by hurricanes and drenched with floods.
