The most recent trends in sea level rise mean the low-lying Camargue region of southern France could be submerged by the sea by the end of the century. The sea walls built along the coast in the 1980s have already been broken by the waves, as a combination of rising waters, slowly sinking landmass, and reduced amounts of sediment from the Rhone river spell trouble for this environment. Anis Guelmami uses Copernicus Sentinel satellites to study wetlands like the Camargue, and he tells us the latest news from space.
