New NOAA Sea Level Projections — It is not good news
Sea level is rising. This is a well-established fact. The rate at which sea level is rising is also accelerating.
Between 1901 and 2018 sea level has risen by 6–10 in. That insight comes via tide gauges. It sounds like a simple measurement, but working that out is deeply complex. Land itself rises and falls, so you also need to account for that.
