NASA Sea Level Change Observations from Space: Click anyplace on a map of Earth’s ocean, and you can get an instant reading of sea-level change – whether close to home or far away. Click on coastlines around the world, and you’ll receive a detailed report on the major contributors to changing sea level at each location.

It covers the period between 1993 and 2019. In most places, you’ll find sea levels rising; globally averaged sea level has increased significantly over decades. But quirks of ocean currents, rising or falling coastlines, and even gravity itself mean sea-level change is not uniform across the planet…”
