GLOBAL IMPACT ASSESSMENT OF SEA LEVEL RISE BASED ON RCP/SSP SCENARIOS

Abstract

 The objective of this study was to assess global impact of sea level rise based on RCP/SSP scenarios. Global areas of inundation due to seal level rise and astronomical high tide were identified. Combining the results of inundated areas based on RCP scenarios with SSP scenarios, the populations affected and the economic damages caused by inundation due to future climate change were also estimated. Consequently, potential inundated areas vary 370 thousand km² (RCP2.6) to 420 thousand km² (RCP8.5) and affected population vary 55.3 million (RCP2.6, SSP1) to 106 million (RCP8.5, SSP3) in 2100. This quantitative information is expected to be valuable in implementing desirable adaptations according to the regional conditions.
