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 these 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.”
