The CCWGI shares its experience and findings with public organizations and utility service providers, thereby enhancing the non-government infrastructure’s resilience. Sea level rise and Hong Kong Sea level rise is an inevitable consequence of a warming world. There are many uncertainties to reflect upon for decision-making. The issue is the timing and extent of sea level rise over the coming decades (up to 2050) and further out in this century (up to 2100) so that it could consider what types of adaptive measures would be needed in which locations, when and how to construct them, and the cost implications. HKO based its sea level rise projections on the range of GHG emissions scenarios as per IPCC AR6. In summary, there is greater certainties near-term than longer-term. IPCC AR6 and local studies show that there are insignificant differences in sea level rise projections going out to 2050 under the intermediate and very high emissions scenarios. However, the
