Our planet is getting warmer every year, and the horrible fact is, global warming is accelerating. As a natural result, the glaciers are melting at an increasing speed. What if all the Earth’s ice melted?

Almost 10% of the world’s land surface is currently covered with glaciers, mostly in places like Greenland and Antarctica. The amount of water locked up in ice and snow is only about 1.7 percent of all water on Earth (332,500,000 cubic miles, or 1,386,000,000 cubic kilometers), but the majority of total freshwater on Earth, about 68.7%, is held in ice caps and glaciers. And if all land ice melted the seas would rise about 70 meters (about 230 feet).

What if all this ice melted? What would Earth look like? Alex Kuzoian of Business Insider prepared a video showing the effects of the global melting, and if it happens, “this would dramatically reshape the continents and drown many of the world’s major cities.”

How Earth would look if all the ice melted

What is all the Earth’s ice melted

  • The global sea level would be about 70 meters (230 feet) higher.
  • Most of the coastal cities around the world would be under water, including Sydney, Adelaide, Perth, Calcutta, Miami, Venice, Saint Petersburg, Shanghai, Buenos Aires, Rio de Jenerio, New York City, Houston, New Orleans, and Stockholm.
  • These cities are some of the wealthiest ones of the world. Loss of these cities would mean the global economy come down crushing.
  • If all the ice melted, sea currents would change drammatically. Some of them would collapse. This would cause mass extinction of sea creatures as well as polar animals.
  • There would be an inland sea on Australia continent.
  • A large part of Sahara desert would be under water.
  • Red sea and Persian gulf would be much bigger.
  • Hurricanes will be more frequent and more powerful as more heat means they will carry more moisture.
  • In North America, the entire Atlantic seaboard would vanish with its coastal cities. San Francisco’s hills would become an archipelago (a cluster of island)s and the Central Valley would be a giant bay.
  • In South America, the Amazon Basin and the Paraguay River Basin would become Atlantic inlets.
  • In Asia, the Caspian Sea would be much, much bigger. The area currently at least one billion people live in would be claimed by the rising sea.
  • In Europe, the Netherlands would completely vanish. Most of Denmark would be gone too. Brussels would be a coastal city.
  • West Antarctica would be an archipelago, while the east staying as a continent. Since 1992, on average, Antarctica is losing about 65 million metric tons of ice every year.

Photo by Commander Mark Moran, of the NOAA Aviation Weather Center, and Lt. Phil Eastman, and Lt. Dave Demers, of the NOAA Aircraft Operations Center, all commissioned officers of the NOAA Corps, flew more than 100 hours surveying Katrina’s devastation. Eastman piloted NOAA’s Bell 212 Twin Huey Helicopter from August 31 to September 19. All three men took dozens of aerial photos from an altitude of several feet to 500 feet (150 meters). – Public Domain, Link
