This maps show the estimated multiplication factor, by which the frequency of flooding events of a given height changes between 2010 and 2100 due to projected regional sea relative level rise under the RCP2.6 and RCP8.5 scenarios. Values larger than 1 indicate an increase in flooding frequency. Adapted from Figure 4.12 of the Intergovernmental Panel on Climate Change (IPCC) Special Report on the Ocean and Cryosphere (SROCC).
