Table 1 Average net shoreline change for CoSMoS-COAST and Anderson et al.⁵ models for 0.3 m and 1.2 m of SLR using the 80th percentile projections.

SLR [m]	SLR timing	Model	Average [m]	Median [m]	Standard deviation [m]	Min	Max	Average (BRU + LTR) [m]	Standard deviation (BRU + LTR) [m]
0.3 m	June 2050	Anderson 2018	− 8.49	− 8.53	7.49	− 86.79	26.43	− 8.49	7.49
0.3 m	June 2050	CoSMoS—COAST	− 12.16	− 11.74	15.06	− 78.38	63.70	− 5.66	8.10
1.2 m	June 2100	Anderson 2018	− 31.84	− 31.58	21.69	− 186.74	70.91	− 31.84	21.69
1.2 m	June 2100	CoSMoS—COAST	− 33.19	− 31.39	21.87	− 138.34	57.62	− 17.52	19.13

Last two columns show average and standard deviation net shoreline change from only the change due to SLR (BRU) and long-term linear processes (LTR). The last two columns (Average BRU + LTR and Standard Deviation BRU + LTR) for the Anderson et al. model rows are identical to the first two columns (Average [m] and Standard Deviation [m]), since, conceptually these are the same values (See Eq. 1).
