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.

The IPCC’s Special Report on Oceans and Cryosphere – What it means for Africa’s coastal cities

For African coastal cities, sea level rise and increasing storm frequency and intensity pose serious threat. West, Central, East and Mediterranean coastal zones in Africa are very low-lying. Within these low-lying coastal zones are many of Africa’s largest cities: Dakar, Abidjan, Accra, Lagos, Dar es Salaam, Alexandria, Tripoli, and Cape Town.

Dual approach needed to save sinking cities and bleaching corals

Local conservation can boost the climate resilience of coastal ecosystems, species and cities and buy them precious time in their fight against sea-level rise, ocean acidification and warming temperatures, a new paper by scientists at Duke University and Fudan University suggests.

What will Malibu’s beach erosion problem look like in 20 years?

The rapid erosion of Malibu’s beaches in the past few years is nothing short of startling and has drawn the concerned attention of local citizens, advocacy groups and public officials. Beach erosion, attributable in part to climate change and in part to the hand of man, is pervasive, invasive and expensive.

Erosion threatens scenery and real estate along iconic California coastline

This is supposed to be a beautiful beach, but instead it looks like a disaster area because a sea wall built about a decade ago to protect homes has failed. Now property owners are spending millions to fix it. From Mexico to Oregon, the iconic California coastline runs more than 3,400 miles.

Rising tides force Miami Beach residents to seek higher ground

Scientists with the United Nations Wednesday released their most alarming report yet on climate change. Oceans are warming, sea levels are rising and polar ice is melting — all of that is accelerating because of increasing carbon dioxide levels. But the report warns the harshest consequences may be on low-lying coasts, where almost 700 million people live.

Who will pay for the huge costs of holding back rising seas?

U.S. coastal cities face billions of dollars in costs for the extensive infrastructure projects needed to protect against rising seas and worsening storms. From Boston to Miami, government officials are only beginning to grasp the enormous expense of what will be required.
