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.

Melting Glaciers Cause One-Third of Sea-Level Rise

patagonia-glacier

The world’s glaciers lost 260 gigatons of water each year between 2003 and 2009, making these rivers of ice responsible for almost a third of sea-level rise in that time, new research finds.

Denying Sea-Level Rise: How 100 Centimeters Divided The State of North Carolina

On the surface, it looks like America is a place where scientists and scientific achievements are held in high regard. However, just below the surface, there is another America. This America is populated by people who, on economic, political or religious grounds, have chosen to reject the consensus of the global scientific community on various topics. By Alexander Glass and Orrin Pilkey.

East Coast Rebuilding, But Vulnerable to Future Sandys

Katrina-Like Storm Surges Could Become Norm

Last year’s devastating flooding in New York City from Hurricane Sandy was the city’s largest storm surge on record. Though Hurricane Sandy was considered a 100-year-event, a storm that lashes a region only once a century, a new study finds global warming could bring similar destructive storm surges to the Gulf and East Coasts of the United States every other year before 2100.

Antarctica’s topography began changing from flat to fjord-filled starting about 34 million years ago. Knowing when Antarctica’s topography started shifting from a flat landscape to one with glaciers, fjords and mountains is important for modeling how the Antarctic ice sheet affects global climate and sea-level rise.
