Do you know everything that contributes to sea level?

The NASA feature article on Vital Sings on the Planet, NASA-led Study Reveals the Causes of Sea Level Rise Since 19900 (8/21/2020) summarizes results from the paper in Nature, The causes of sea-level rise since 1900 (behind a paywall). What you might not have known:

In addition, the new study found that during the 1970s, when dam construction was at its peak, sea level rise slowed to a crawl. Dams create reservoirs that can impound freshwater that would normally flow straight into the sea.

For example, in its recentĀ flooding report, the National Oceanic and Atmospheric Administration (NOAA) noted a rapid increase in sea level rise-related flooding events along U.S. coasts over the last 20 years, and they are expected to grow in extent, frequency, and depth as sea levels continue to rise.

Sea level data can be found on NASA’s Sea Level page.
