Of the 28 coastal departments of mainland France, not all will be hit in the same way. From 4,000 homes threatened in 2050, we reach almost 450,000 in 2100, an increase of more than 1,000%.

Haute-Corse and Corse-du-Sud are among the most affected in the 2050 scenario. Nord and Pas-de-Calais are very exposed in the 2100 scenario because part of these departments are located below sea level. For researchers, these territorial disparities must push the State and communities to think about solutions at the local scale.
