Source: Figure 13.27 -- Chapter 13 IPCC AR5 WG1 Report. Compiled paleo-sea-level data from geological evidence to 1880, tide gauge data from 1880 to present, altimeter data since 1993 to present, and central estimates and likely ranges for projections from present to 2100 based on RCP2.6 (blue) and RCP8.5 (red) emission scenarios.
Global Sea-Level Rise: 1700 to 2100
Source: Figure 13.27 -- Chapter 13 IPCC AR5 WG1 Report. Compiled paleo-sea-level data from geological evidence to 1880, tide gauge data from 1880 to present, altimeter data since 1993 to present, and central estimates and likely ranges for projections from present to 2100 based on RCP2.6 (blue) and RCP8.5 (red) emission scenarios.
• Human-induced sea-level rise and climate change has a major impact potential for coastal areas
• Climate mitigation has immediate benefits on temperature-related climate change factors
• However, it will stabilise but not stop climate-induced sea-level rise (the sea-level rise ‘commitment’) which continues for centuries
• Hence, the most appropriate climate policy response is a combination of climate mitigation to make sea-level rise manageable and adaptation to the “residual” committed sea-level rise
• Such adaptation will be need to be ongoing with implications for adaptation funding
