The 2022 Sea Level Rise Technical Report, a "multi-agency effort, representing the first update since 2017, offers projections out to the year 2150". Figure 2.2 provides "observation-based extrapolations using tide-gauge data and five Scenarios, in meters". The sea level values are relative to a baseline of zero meters in the year 2000. The vital signs sea level chart cited for this wager depicts a rise between 1993 and 2000 ranging from a minimum of 19.8 mm (July 2000) to a maximum of 29.4 mm (October 2000). For mk's prediction to come true, a minimum additional 372.6 mm of rise must occur between 2000 and January 2040 (29.4 mm 1993-2000 + 372.6 mm 2000-2040). Table 2.1 shows predicted median values for 2040 ranging from 250 mm (Low scenario) to 350 mm (High scenario). The "likely range" of the High scenario is 180 mm to 390 mm.
