What is Doomsday Glacier?
The Thwaites Glacier, better known as the “Doomsday Glacier,” is one of the most critical and concerning glaciers on the planet. Located in West Antarctica, this ice mass has the potential to dramatically raise global sea levels.
It covers an area of approximately 74,000 square miles—roughly the size of Florida.
But what makes this glacier so dangerous? And what would happen if it melted entirely?
It has captured the attention of scientists and climate experts worldwide. In this article, we will explore the reasons behind it.
According to The World, it holds enough ice to raise global sea levels by over 10 feet if it were to melt completely.
The glacier is known as the “Doomsday Glacier” because it can significantly raise global sea levels.
What makes this glacier dangerous is that it is already showing signs of instability. In recent years, scientists have observed that it is melting at an alarming rate.
Warm ocean water is getting underneath the glacier, causing it to detach from the bedrock and flow more rapidly into the sea.

Impact on Sea Levels
According to BBC, if this glacier collapses entirely, it could raise global sea levels by approximately 3-10 feet (1-3 meters).
While this may not sound like much, the consequences would be catastrophic.
This could lead to the flooding of major coastal cities and the displacement of millions of people. Valuable infrastructure and ecosystems could be lost, and entire nations, particularly low-lying island countries, could be submerged.

Scientific Research & Findings
Several scientific studies confirm the instability of the Doomsday Glacier. A study published in Nature in 2019 found that warm ocean water was rapidly melting the glacier from underneath, making it increasingly unstable.
The study also highlighted that the glacier’s grounding line—the point where it rests on the seabed—has been retreating by nearly 2,000 feet per year.

Another study published by the International Thwaites Glacier Collaboration in 2021 used satellite data to monitor changes in the glacier’s ice flow and thickness.
The research confirmed that it is losing ice at an accelerated rate. At this speed, it could significantly increase sea levels in the coming decades.

Hypothetical Present-Day Impact
Now, let’s imagine a scenario where the Doomsday Glacier melts entirely in the present day. The resulting sea level rise could be catastrophic, with the most immediate impact felt in coastal regions around the world.
United States
Coastal cities like New York, Miami, and New Orleans would experience severe flooding. A 3-foot rise in sea level could submerge parts of these cities, displacing millions of residents.
Netherlands
As Netherlands is below sea level it would be extremely difficult for it to keep its cities protected.
Bangladesh
A country where flooding is already a problem, a rise in sea level could lead to unimaginable crisis.
Mumbai, India
As a coastal city with a high population density, Mumbai would face severe flooding, affecting millions of residents and infrastructure.
Island Nations
Countries like the Maldives, Tuvalu, and Kiribati could be entirely submerged, forcing their populations to relocate.
Historical Comparisons
Historically, even small rises in sea level have had severe impacts on coastal regions. For instance, during the last Ice Age, sea levels were about 400 feet lower than they are today.
As the ice melted and sea levels rose, entire land bridges, such as the one connecting Asia and North America (Beringia), were submerged.
This led to significant changes in human migration patterns.

In more recent history, the city of New Orleans was devastated by Hurricane Katrina in 2005.
Although the sea level rise at the time was less than a meter, the storm and flooding caused by the hurricane led to widespread destruction and loss of life.
This example shows how even minor changes in sea level can have severe consequences when combined with other factors like storms.

Conclusion
The Doomsday Glacier represents a significant threat to global sea levels. While it may take decades to make the impact, the consequences would be felt for generations to come.
The threat is real, and we should act as soon as possible to prevent such catastrophe.
By drawing comparisons and using relatable examples, we can better grasp the severity of the situation. The Doomsday Glacier is not just an abstract concept but a real and present danger that requires global attention and action.
