The frozen water at the Earth’s poles and in glaciers is melting due to human-induced climate change. Rivers of Arctic meltwater are running into the sea and chunks of ice are breaking off causing extreme weather events around the world. Massive amounts of frozen water are stored in three large areas on Earth. The largest is Antarctica, entirely covered in ice sheets. If this goes into meltdown mode, the sea level will spike with a catastrophic global impact.
Next is the Arctic, which includes Alaska, Canada and Greenland and is warming about four times faster than the rest of the planet. The size of Greenland’s ice sheet is mind-boggling at nearly 2 miles (3.2 km) deep. Were all of this ice to melt, the sea could rise 20 feet (6 m). The glaciers of the Himalayas are known as the Third Pole. Melting here may harm ecosystems and billions of people. Another concern about melting ice is the albedo effect. Since dark waters absorb more heat than white ice, less ice causes the Earth to warm even more in a destructive feedback loop.
