The Grand Océan Festival invites you from September 13 to 15, 2024 for its 3e edition. It will be held mainly at La Cité de La Mer in Cherbourg-en-Cotentin on Friday 13 and Saturday 14 and in Réville on Sunday 15 September around a central theme: “Thinking about and protecting the coastline and islands”
Thinking about and protecting the coastline and islands
Erosion of beaches and dunes, land movements, marine submersion… The retreat of the coastline observed today is linked to climate change. Firstly, to the thermal expansion of the oceans, a phenomenon by which the volume of the oceans increases in response to a rise in the temperature of its waters.
At the same time, glaciers and ice caps in Antarctica and Greenland are shrinking drastically: each year, 270 billion tons of ice disappear in Greenland, according to recordings from NASA’s Grace satellite missions. The contribution of melting ice caps now accounts for a third of sea level rise. But it is mainly extreme weather events that aggravate coastal erosion in the short term.
According to satellite observations, the rise in sea level is accelerating and is now approaching 5 millimeters per year. The crucial question now is how to adapt the coastline to climate change and anthropogenic pressure. As sea levels continue to rise, an increasing number of regions in the world will be exposed to coastal flooding. In France, all coastal areas are threatened with erosion by the end of the century.
Dominique Leglu, editorial editor of Science and Futurepresents the festival in these words: “With climate change, today […]
