What If All the Ice on Earth Melted: Here’s What Can Happen

What would happen if all the ice in the world had to melt? Can you imagine the catastrophe? What if a sudden surge of climate change suddenly melted all the polar ice caps on Earth overnight, there would be an unfathomable disaster beyond your comprehension? The question is what exactly would happen? Would you wake up to find yourself lying in water or even drowning? Would you find your entire country submerged or would sudden atmospheric changes choke the life out of you? It is a frightening scenario but rather than contemplation, lets really find out what would happen if all the ice on earth melted.


1Does an ice cube melt in a glass filled with water?

When you drop an ice cube into a glass of water filled to the brim, does it change the water level? Well! Actually, it doesn’t. Regardless of above or below the water line, a melted ice cube replaces exactly the same amount of water.

2Now, what would happen when you add salt to the water?

If you add a 1 cubic inch ice cube to the glass filled with water, the water level rises 0.03 cubic inches which is displaced salt water. The volume of water is increased by 2.6%. Now that may seem a very tiny amount when you speaking about a glass of water but what about the earth.

3How much ice exists on the planet?

The Earth is covered by 5.8 million square miles of ice. Almost all of it is stored in the ice shelves of Greenland 10% and Antarctica 90%. If all of it melted overnight, sea levels would rise 230 feet. That sentence alone is enough to fuel the horrors of any imagination.

4It could cover the Tower of London

Well, that’s the first thing that comes to mind. If the ice on the planet rose 230 feet, it would be enough to cover the London’s Tower Bridge. But that’s not all that would happen. There would be flooding everywhere.

5Every continent would be underwater

Besides all continents being underwater completely or partially, you can forget about cities like Miami and London. Being almost surrounded by water, these cities would be totally submerged and become water worlds instead.

6What would happen to Australia?

Coastal Australia would be washed away along with 80% of residents. Australia too is a vulnerable region that could suffer bad consequences if the ice caps were to melt. That means almost half of Australia would perish and the rest flooded completely.

7Venice and Netherlands would suffer a similar fate

Although we use Venice and Netherlands as an example of cities that would be washed away and totally submerged, there are many more coastal cities of a similar nature that may suffer similar fates. Popular islands in the Caribbean, the Pacific, and the Indian Ocean would vanish.

8Africa would suffer an opposite fate

Although flooding may not affect Africa all that much, the continent would experience extremely high temperatures and heat waves that would make the region uninhabitable. That’s a weird scenario.

9The aftermath faced by humanity

Although flooding will still not be enough to wipe out humanity, the aftermath will be equally disastrous. Survivors would then face several perilous situations and dangers because of atmospheric changes.

10Melted ice will release CO2

All the melted ice will release huge amounts of carbon dioxide into the air. Ice needs a high concentration of Co2 to melt; the oxygen content in the atmosphere will remain the same. However because of the presence of high CO2 humans would suddenly choke by breathing.

11There would be no time to acclimatize

There would be very little time for life to acclimatize because ocean currents will change. The new atmosphere on land and sea will affect sea life and polar animals leading to their extinction.

Animals will be forced to change habitats and seek out other favorable climates to live in leading to a decrease in the food supply for humans.

12Extreme weather changes

There will be extreme weather changes with heavy rainfall in deserts. Areas that once received heavy rainfall will dry up leading to global famine because of the inability for agriculture. But that isn’t all.

13Wind patterns would change flooding mountain areas

Wind patterns will change and there will be no ice to reflect the sun’s rays. The sun will start drying oceans and drawing more moisture creating more clouds. Clouds gathering near mountain areas will result in heavy rainfall and flooding.

14Small earthquakes would create large tsunamis

There would be an increase in ocean currents. Small coastal earthquakes would be enough to create giant tsunamis. This would result in mass human migration and an ensuing chaos because it would be unmanageable by governments.

15World order may collapse

The chaos of people wanting to travel to favorable areas would be so great and overwhelming that world government would collapse because of attempts to stop it. Borders would be breached and the concept of countries with birders would cease to exist.

16The actual warning with a sigh of relief

Well! Such a scenario is a wakeup call for us humans who are bleeding the planet. Fortunately, the ice cannot melt overnight but it has started melting especially the oldest ice core that is storage of the planets geographical information for the last 1.5 million years.

17But! In 5000 years the earth will be ice-free

Because man is constantly adding fuel to the fire of climate change and global warming, the ice will certainly melt in 5000 years time. Do you believe we need to protect our planet?? Then share this article.
