Line graphs of monthly sea level at the Fort Pulaski, GA, tidal station each year from 1935–2021, showing how they compare to the local mean sea level (1983–2001, dashed black line). Each year appears first as a black line, and changes to a permanent color as the animation plays. Darker-colored lines indicate earlier years; lighter-colored lines indicate more recent years.
