'Poised to disintegrate': Antarctica's '#DoomsdayGlacier' is set to lose its #IceShelf this year

#WestAntarctica's "Doomsday Glacier" is on the brink of losing its ice shelf, further compromising the already melting ice mass and threatening to unleash devastating sea-level rises.

By Patrick Pester

"A vital ice shelf is about to break away from Antarctica's "Doomsday Glacier," further destabilizing one of the world's largest and most vulnerable glaciers.

The #ThwaitesGlacier is nicknamed the "Doomsday Glacier" because its collapse would send so much ice into the Southern Ocean that #GlobalSeaLevels would rise by 2.1 feet (65 centimeters or 26 inches), flooding coastal communities worldwide. This collapse could take centuries, but there is an imminent threat to Thwaites' eastern ice shelf, which will likely accelerate the glacier's demise.

"Researchers say that satellite images reveal that the Thwaites eastern ice shelf is about to detach from the glacier, New Scientist reported last week. While the glacier sits on land, the ice shelf is a floating body of ice that is attached to the glacier's mouth. Researchers still have a lot to learn about the glacier, but this shelf acts as a buttress, restraining the flow of ice from the glacier into the sea."

[...]

"Thwaites Glacier's slow collapse is part of a wider concern among scientists for the future of the West #Antarctic ice sheet. Thwaites is a key pillar of the ice sheet, protecting other ice from slipping into the ocean. If the whole ice sheet were to go, sea levels would rise by 10.8 feet (3.3 m), according to the British Antarctic Survey. The collapse of ice sheets like this one are considered tipping points, or 'points of no return,' in the fight against climate change — meaning that once they are crossed, they bring about permanent changes that cannot be reversed for many thousands of years."

Researchers issue warning after making grim #Antarctic discovery: 'We are only beginning to understand'

Story by Daysia Tolentino, January 29, 2026

Excerpt: "A study published in the journal #Biocontaminant examined the effects of #GlacialMelting on our #WaterSupply.

"#Glaciers serve as reservoirs for #AntibioticResistanceGenes, or #ARGs, and other #microbes. When they are released from the ice, they enter our water systems, posing a major health risk to people downstream.

"Millions of people get their water from glacier-fed rivers and lakes. ARGs are strands of DNA that make bacteria more resistant to drugs. When ARGs in #meltwater make their way into our water supply, they become a global public health risk.

"The study emphasizes the importance of viewing glaciers, rivers, and lakes as being part of a 'glacier continuum.' This means they are an interconnected system rather than separate environments.

Why are melting glaciers concerning?

"From our gas-powered cars to #overconsumption, human activity has contributed to the production of heat-trapping gases that warm the planet. Rising global temperatures have caused glaciers to rapidly melt, causing elevated sea levels and releasing ARGs.

"ARGs from melting glaciers are worrisome because they help facilitate the spread of diseases. This threat is compounded by the fact that our growing #microplastic problem is also helping #AntibioticResistant #bacteria breed. As a result, #medicines are being rendered less effective."

Melting #Antarctic ice sheets may be causing larger volcanic eruptions

During #deglaciation, melting of kilometers-thick #IceSheets reduces the mass weighing down the land, which leads to #uplift. This alters the pressure inside #magma chambers lying below the Earth's surface, causing #volcanic eruptions.
