Regional projections of Sea-level Rise in French Overseas Territories

摘要

Over the coming decades, sea-level rise will increase the severity of flooding events impacting French coastal areas. Given this prospect, a sea-level rise of 60 cm by 2100 has been assumed and adopted in French regulations related to coastal flooding. The accuracy of this working hypothesis is considered here by comparing the adopted value with projections recently produced by the IPCC. Based on this comparison, it can be concluded that the risk is currently underestimated.
