Almost 50 million Europeans live within 10 m above mean sea level . Without further adaptation , flood risks along Europe's low-lying coasts and estuaries will increase due to SLR compounded by storm surges, rainfall and river runoff  . The population at risk of a 100-year flood event starts to rapidly increase beyond 2040  reaching 10 million people under RCP8.5 by 2100, but it stays just below 10 million people under RCP2.6 by 2150  assuming present population and protection. The number of people at risk is projected to increase and risk to materialise earlier especially in response to increasing population under SSP5 . Under high rates of SLR resulting from rapid ice sheet loss from Antarctica, risks may increase by a third by 2150 . Expected annual  damages due to coastal flooding are projected to rise from 1.3 billion EUR today to 13- 39 billion EUR by 2050 between 2ºC and 2.5℃ GWL and 93-960 billion EUR by 2100 between 2.5° and 4.4ºC GWL, largely depending on socioeconomic developments  . UNESCO World Heritage sites in the coastal zone are at risk due to SLR, coastal erosion and flooding  as are coastal landfills and other key infrastructures in Europe .
