The world’s coastlines are at the forefront of climate change. That’s because they’re constantly changing, and respond quickly to changes in climate. They’re particularly important because around 70 percent of the world’s population live within 100 km of the coast, and 90 percent of the world’s trade passes through ports on the coast. The global economy relies on our coastal systems functioning because of the volume of trade and commerce that takes place at or through the coastal zone.
Change and disruption do not fall evenly across the globe, however. Our new research is the first to find a group of coastal locations around the world highly vulnerable to one specific climate-driven change: stronger waves, or waves coming from a different direction, which may cause widespread coastal erosion.
These changes will affect major ports and coastal cities such as Lima, Cape Town, Durban and Mombasa, as well as broadly affecting the Pacific-facing east coasts of Peru and Chile, the Atlantic-facing west coasts of Namibia and South Africa, and the southeast coast of Kenya down to South Africa.
Many of these locations are in developing nations […]
