Did You Know 90% Of The World's Freshwater Is Locked In The Antarctic Ice Sheet? Here’s The Surprising Fun Fact

Fun Facts About Antarctica: When we think of freshwater, we typically imagine rivers, lakes and precipitation. However, did you realise that none of those locations contain nearly 90% of the freshwater on Earth? Actually, it's trapped in Antarctica's huge ice sheets. The largest freshwater reserve on Earth is found on this frozen continent at the southernmost point of the planet. With ice layers thousands of meters thick, Antarctica covers an area of more than 14 million square kilometres.

This enormous area of ice controls the Earth's temperature and climate in addition to influencing sea levels worldwide. Unexpectedly, Antarctica is the coldest, driest and windiest continent, yet it contains the majority of our planet's water in frozen form. This is even though it is referred to as a desert because it receives very little rainfall. The significance of Antarctica to the Earth's equilibrium and the importance of preserving this icy wilderness for the future of our planet are demonstrated by this amazing fact.

About 90% of the freshwater ice and 60% of the freshwater on Earth are found in Antarctica. Global sea levels could rise by more than 58 meters if all of the Antarctic ice melted, inundating large coastal cities. In some locations, the 4.8-kilometre (3-mile) thick ice sheet can hold frozen water for thousands of years.

Why So Much Water Is Locked In Antarctica?

Since snow and ice cannot melt due to the intense cold, layers can accumulate over time. Ancient air bubbles are trapped in these frozen layers, providing scientists with important hints about the climate and atmospheric changes of Earth's past.

Antarctica’s Role In Climate Balance

The Antarctic ice sheet serves as Earth's natural thermostat. The planet is cooled by the reflection of sunlight off its bright white surface. Melting ice, however, poses a threat to this equilibrium as global temperatures rise, resulting in rising sea levels and global climate disruptions.

* Some ice in Antarctica is more than one million years old.

* Lake Vostok, one of the biggest freshwater lakes in the world, is one of the subglacial lakes on the continent that are concealed beneath thick ice sheets.

* Antarctica gets less precipitation than most deserts, even though it is covered in ice.

Why It Matters

Earth's water supply and climate are silently protected by the Antarctic ice sheet. Preventing catastrophic sea-level rise and preserving environmental stability for future generations depend on protecting it from global warming.
