Three major global cities\u2014London, New York, and Bangkok\u2014could be submerged if Antarctica\u2019s \u201cDoomsday Glacier,\u201d officially known as Thwaites Glacier, collapses. Scientists say this scenario is becoming more likely.<\/p>\n
Thwaites holds enough ice to raise sea levels by over two feet, but a full collapse could destabilize the larger Antarctic ice sheet, causing sea levels to rise by up to 10 feet. This would trigger catastrophic flooding in many coastal cities.<\/p>\n
Ongoing research by the International Thwaites Glacier Collaboration (ITGC), launched in 2018, has revealed hidden lakes beneath the glacier that are accelerating its melting. A 2025 study led by Professor Noel Gourmelen showed that drainage from these subglacial lakes significantly speeds up ice loss.<\/p>\n
The effect, described as a \u201cturbo charge,\u201d comes amid record Southern Hemisphere temperatures, raising alarm over the glacier\u2019s stability. Dr. Alastair Graham, another ITGC researcher, warned, \u201cThe game has changed.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
