How would sea level change if glaciers melted?

  • If all of the glacier ice on Earth were to melt, sea level would rise ~ 80 m (~ 265 ft), flooding every coastal city on the planet.
  • If all of Earth’s temperate glaciers melted, sea level would rise ~ 0.3 – 0.6 m (~ 1 - 2 ft).
  • If all of Greenland’s glaciers melted, sea level would rise ~ 6 m (~ 20 ft).
  • If all of Antarctica’s glaciers melted, sea level would rise ~ 73 m (~ 240 ft).
  • If all of Alaska’s glaciers melted, sea level would rise ~ 0.12 m (~ 4.7 in).
