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.

Our Expanding Oceans, and Global Climate Change: A Primer

Our Expanding Oceans exhibit is based on a new book, “Global Climate Change: A Primer,” written by renowned climate scientist Orrin Pilkey and son Keith Pilkey. To visually emphasize the effects of climate change, the book is illustrated with Mary Edna Fraser’s striking batik paintings. The exhibit featuring over 50 batiks on silk, opened at the North Carolina Museum of Natural Sciences.

Study details significant sea level rise

beach-erosion-carolina-ry-1

Since the late 19th century, sea level has risen by more than 2 millimeters per year on average, the steepest rate for more than 2,100 years. The new study does not predict the future, yet it does show “there is a very close link between sea level and temperature. So for the 21st century when temperatures will rise, so will sea level.”

Cuba: Sea levels to rise more than 30 in. by 2100

Cuban scientists warn that right now it is urgent to preserve mangroves, coral reefs, sea grass and sand beaches. Each of these ecosystems is a natural barrier to defend the coasts from the impact of climate change and sea level rise. Most of the 400 beaches of Cuba’s territory are affected by erosion with a receding coastline estimated at 1.2 meters per year.

The Last house of Sinking Chesapeake Bay Island

November 27th, 2010

The story was strange enough to be a child’s fable: In an isolated section of the Chesapeake Bay, there was a two-story Victorian house that seemed to emerge directly from the water. And, scurrying around it, there was a retiree, trying to keep the house from falling in.
