3 Major Cities That Could Vanish If The ‘Doomsday Glacier’ Collapses
It is stated that if the so-called “Doomsday Glacier” melts, three cities could be engulfed.
Experts have warned of the disastrous outcomes that could occur in the future if something is not done quickly. Scientists have frequently discussed how climate change has caused sea levels to rise and temperatures to rise globally.
Reports on the Thwaites Glacier, often known as the “Doomsday Glacier,” which contains enough water to raise sea levels by more than two feet, have helped put the true effects of global warming and what it might imply for the future into perspective.
Thwaites serves as a “cork” to the wider Antarctic ice sheet, and its collapse might raise sea levels by about 10 feet, which would significantly affect cities all over the world.
Cities like Bangkok, New York, and London, which welcome millions of tourists each year, may potentially be submerged in water as a result of such a catastrophic occurrence.
The Doomsday Glacier’s potential effects on humanity are the subject of numerous research, yet obtaining the necessary answers is not as easy as it seems.
In essence, there are many “hidden lakes” in the glacier, and these alone may have a bigger effect than scientists first thought.
The International Thwaites Glacier Collaboration (ITGC), which has been researching the glacier since 2018, has concluded that this century will see an acceleration in ice loss, to the point that the entire glacier may collapse in as little as 200 years.
Professor Noel Gourmelen, lead author of a March 2025 study and member of the ITGC, said: “We expected that water draining from the underside of the ice sheet plays a role in modulating ocean melting, the sheer magnitude of this lake drainage gave us the opportunity to finally observe and quantify its impact.”
“The lake outflow took place in a key sector impacting Thwaites’ stability, the drainage in effect momentarily turbo-charged Thwaites’ ocean-driven retreat.”
Hotter than anticipated In the Southern Hemisphere, 2025 has so far alarmed scientists and is thought to have accelerated the problem.
Speaking to News.com.au, University of South Florida’s Dr Alastair Graham said: “If Thwaites Glacier collapses it would cause a rise of around 65cm (25 inches) in sea level.”
“This year is really different. It’s very difficult to recover from this in one season. The game has changed.”
