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.

Natural Defences Can Sharply Limit Coastal Damage

sand-dunes

Coastal forests, coral reefs, sand dunes, marshes and wetlands are just a few of the natural habitats that protect two-thirds of the US coastline from hazards such as hurricane, and are key to protecting lives and property against storm surges and long-term sea-level rise.

Pakistan’s Coast And Encroaching Seas

indus-delta-pakistan

Encroaching seas are leaving farmland increasingly saline and water-logged, and leading to a decline in fresh water fish stocks. These trends are being studied by the World Wide Fund for Nature Pakistan (WWF-P) which is in the middle of a five-year project to build climate change resistance on Pakistan’s coastline, where communities are vulnerable to cyclones, rising sea levels and storm surges.

Hurricanes Likely to Get Stronger and More Frequent

port-au-prince-post-Ike-hurricane

Hurricanes are Mother Nature’s largest and most destructive storms. Fed by warm ocean waters and moist atmospheric conditions, about 90 such storms, also known as tropical cyclones, form worldwide each year. With the population of coastal areas growing daily and sea level on the rise, how these monster storms may change as the climate continues to warm is an increasingly urgent question facing climate scientists, insurance companies, and public officials.

Scientists Image Vast Subglacial Water System

antarticque

In a development that will help predict potential sea level rise from the Antarctic ice sheet, scientists have used an innovation in radar analysis to accurately image the vast subglacial water system under West Antarctica’s Thwaites Glacier. On its own, Thwaites contains enough fresh water to raise oceans by about a meter.

The project links a pair of strange bedfellows: One is an oil-rich Persian Gulf state of 8 million ruled by a dynastic monarchy, and the other is a democratically governed island nation of 86,000 where tropical beaches and hotels lure more than 200,000 well-heeled tourists every year.
