120 years of Earth's ocean levels from tide gauge records (and 3 year average) is embroidered on silk and emerges from an oil can.

Over the past century, the average height of the sea has risen more consistently, less than a centimeter every year, but those small additions add up. Today, sea level is 5 to 8 inches (13-20 centimeters) higher on average than it was in 1900. That's a pretty big change. For the previous 2,000 years, sea level hadn't changed much at all. The rate of sea level rise has also increased over time. Between 1900 and 1990, studies show that sea level rose between 1.2 millimeters and 1.7 millimeters per year on average. By 2000, that rate had increased to about 3.2 millimeters per year and the rate in 2016 was estimated at 3.4 millimeters per year. Sea level is expected to rise even more quickly by the end of the century. For more info about global mean sea level, go to NASA and Copernicus or National Center for Atmospheric Research.
