The End of the World Glacier is melting and sea levels could rise by 3 meters

The latest research reveals an alarming scenario: ocean water is advancing miles beneath the Thwaites glacial plate, known as the “Doomsday Glacier.” Located in Antarctica, this glacier could cause a catastrophic rise in sea levels if it completely collapses.

The new research, which used radar data from space to X-ray the glacier, revealed a frightening reality: Thwaites is much more vulnerable to melting than previously imagined.

Saltwater Thawing and Infiltration

Infiltration of warmer, salty water from the ocean is causing “vigorous melting” at the bottom of the glacier. This means that global sea level rise projections may be seriously underestimated. This study, published in the Proceedings of the National Academy of Sciences, paints a worrying picture.

Thwaites Dimensions and Vulnerability

The Thwaites glacial plate is the widest in the world, with a size comparable to that of Florida. However, it is the most vulnerable and unstable in Antarctica, mainly because the land on which it sits slopes downwards, allowing ocean waters to erode its ice.

Current Contribution and Future Implications

To date, this glacier has contributed 4% to global sea level rise. Scientists warn that, due to its position as a natural barrier to the surrounding ice, the collapse of Thwaites could lead to much more significant sea level rise. It is estimated that if all the ice contained in Thwaites melted, sea levels could rise by up to 60 centimeters. However, considering that it acts as a support for other glaciers, the complete destruction of Thwaites could result in a rise in sea levels of up to 3 meters.

Potential Global Impacts

A 3 meter rise in sea level would have devastating consequences for coastal areas around the world. Densely populated cities and low-lying regions would face severe flooding, resulting in mass displacement and significant economic impacts. Critical infrastructure such as ports, airports and residential areas would be under direct threat.

The ‘End of the World’ Glacier

The accelerated melting of Thwaites Glacier highlights the urgent need for global action to mitigate climate change. Recent discoveries highlight the increasing vulnerability of Antarctica’s glaciers and the potential risks associated with rising sea levels. The scientific community and policymakers must collaborate closely to develop effective strategies that can protect coastal populations and preserve the planet’s climate balance.
