Antarctica’s “Doomsday Glacier” Could Raise Sea Levels Twice As Much as Scientists Feared
Even without further warming, Thwaites Glacier could contribute twice as much to sea level rise by 2100 as previously estimated, according to a revised ice sheet model. Thwaites Glacier in West Antarctica has been retreating and thinning rapidly, while satellites show substantial acceleration in its ice flow. Traditional ice sheet models have depicted slower movement,
In January 2026, researchers completed a drilling project beneath 1,716 feet of ice in West Antarctica, recovering evidence of an ocean that once lay open to sunlight
The discovery rewrites Antarctica's climate history—and raises urgent questions about how quickly ice sheets can collapse.
In 2007, scientists used NASA satellite measurements to reveal 14 areas of moving water beneath West Antarctica; one hidden lake had drained about 2 cubic kilometres in three years
Antarctica may look like a vast, frozen and unchanging landscape, but deep beneath its thick ice lies a surprisingly active world. In 2007, scientists reported findings based on measurements collected by NASA’s ICESat satellite between 2003 and 2006, revealing major changes in the surface of the West Antarctic Ice Sheet and signs of water moving through hidden lakes far below.
Scientists stunned as glacier ‘piracy’ unfolds at a pace never seen before - Futura-Sciences
The scene of the heist: West Antarctica In West Antarctica, plenty of glaciers have responded to climate change in the way you might expect: they’re hurrying their flow into the ocean. On average, since 2005, these glaciers have sped up by around 51%. But not every glacier is following the...

A major climate hope in Antarctica just melted away
A popular climate theory suggested that melting Antarctic glaciers would release iron into the ocean, sparking algae blooms that pull carbon dioxide from the air. New field data from West Antarctica reveal that meltwater provides far less iron than scientists once believed. Instead, most of the iron comes from deep ocean water and sediments, not from the melting ice itself. The discovery raises new questions about how Antarctica influences climate change.
