A plot of hourly observed and projected sea level at Scripps Pier between 1961 and 2100. The red line represents the height over baseline (141 centimeters) that sea level currently rises only once every 10,000 hours. By the mid 21st Century, sea level is expected to routinely exceed that height and to remain constantly above it by century's end.
