Detailed explanation-1: -If all glaciers and ice sheets melted, global sea level would rise by more than 195 feet (60 meters).
Detailed explanation-2: -There is still some uncertainty about the full volume of glaciers and ice caps on Earth, but if all of them were to melt, global sea level would rise approximately 70 meters (approximately 230 feet), flooding every coastal city on the planet.

Detailed explanation-3: -Converting ice volume to sea level rise We can calculate the volume of water required to raise global sea levels by 1 mm: Volume = area x height Area = 3.618 x 108 km2 Height = 10-6 km (1 mm) Volume (km3) = (3.618 x 108 km2 ) x (10-6 km) = 3.618 x 102 km3 = 361.8 km3 water.
Detailed explanation-4: -If the Antarctic Ice Sheet melted entirely, it would raise global sea levels by around 200 feet (60 meters).
Detailed explanation-5: -2. Melting sea ice has the potential to raise sea level by several meters. False: Melting sea ice cannot raise global sea level since the ice is already floating. (Think of an ice cube melting in a glass full of water.)
