The year (y-axis) when the present-day 50-year water-event is exceeded annually (left), and, likewise, the year (y-axis) when the present-day 50-year water-level event is exceeded during a daily MHHW tide event (right), as a function of the GEV shape parameter, k, (on the x-axis) for the 202 tide stations used in the current study (with labels provided for a few important tide stations). As in Fig. 2, the color of each tide station represents the magnitude of the GEV scale parameter, σ. The results indicate when the sea-level rise projections, based on the RCP 8.5 emissions scenarios in Kopp et al., (2014)29, exceed the ΔWater Level results shown in Fig. 2. Each data point includes 95% confidence levels, which bound the probabilistic sea-level rise projections29. In general, increasing σ and k delays when the 50-year to 1-year and the 50-year to MHHW regime shifts occur.
