Sea level rise

Global climate models project that the average global sea level will rise by up to 100-120cm by 2100 [10]. The rate of sea level rise will vary, depending on variations in ocean temperature increase and ocean current patterns. Relative sea level across the coast of BC is projected to rise by an average of 20-30 cm by 2100 (90% confidence interval of 10-50 cm) (MaPP regional table).

However, there are many uncertainties in the projections for sea level rise. Localized ocean currents, tidal patterns, and river discharge rates will also influence the observed rate of sea level rise to particular areas. For instance, some models project higher observed sea surface height (SSH) values along the northern coast of BC during the next century in winter and spring related to wind patterns and increasing river discharge [21].
