Australia’s Twelve Apostles
The Twelve Apostles is the name given to a collection of natural limestone stacks that rise up to 150ft (46m) from the sea and were formed by erosion of the original coastline, which began 10 to 20 million years ago.The coast is dynamic and as erosion is ongoing, some more stacks are collapsing while other “Apostles” are likely to form from further erosion of other rocky headlands that line the Victorian coastline.
King Tides Seen as a Model for Rising Seas
The King Tide Photo Initiative 2010, launched by the British Columbia’s Ministry of Environment in Canada, asks individuals to record the possible impacts of sea level rise by photographing high water level events in B.C.’s coastal areas, to help build a photo library and to offer us a chance to visualize what normal sea levels may look like in the future.

Preserving Sydney’s beaches against rising sea levels could cost more than $700 million over the next 50 years and would require the government to reverse its long-standing position regarding offshore sand mining.
Magdalen Islands and Shoreline Erosion, Québec

Cancun’s Beaches: Vanishing Sand and Wasted Money
In a major restoration project last year, millions of cubic yards (meters) of sand were dredged from the sandy bottom of the Caribbean and pumped ashore in Cancun. The project created a seven-mile stretch of beach some 40 to 70 yards (meters) wide, at a cost of about $70 million. It is already washing away.
Bangladesh and Maldives: Sand Export Deal in Sight
Maldives President Mohammed Nasheed expressed keenness to import sand from Bangladesh, as his country would be inundated if the sea level rises by only a metre.
Artificial Offshore Reef Could Stop Serious Beach Erosion
Such costly reef have proved successful in other areas, and it could be the only option to protect the coastline of Old Bar, Australia.
