Detailed explanation-1: -It’s estimated that if all of the ice on the poles melted, sea levels would increase by at least 60 meters (200 feet), due to the ice covering the South Pole (as well as that on and around Greenland) melting, although the ice on Antarctica is not considered to be in danger of melting as soon as the Arctic ice cap.

Detailed explanation-2: -They estimate that the sea will rise 50 centimeters (20 inches) with the lowest estimates at 15 centimeters (6 inches) and the highest at 95 centimeters (37 inches). The rise will come from thermal expansion of the ocean and from melting glaciers and ice sheets.

Detailed explanation-3: -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-4: -If all the ice covering Antarctica, Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet). The ocean would cover all the coastal cities. And land area would shrink significantly.

Detailed explanation-5: -If the Antarctic Ice Sheet melted entirely, it would raise global sea levels by around 200 feet (60 meters).
