Here’s the latest on the Thwaites ice shelf based on the most recent publicly available reporting.
Key takeaways
- The eastern portion of Thwaites’ floating ice shelf continues to be a major focus of attention because it is thinning and cracking, with researchers warning it could collapse in coming years, even as some melting rates beneath the shelf remain complex and not always the dominant driver.[1][4]
- Several recent sources from late 2023 to 2024 highlighted that internal destabilization from growing cracks and rifts in the TEIS (Thwaites Eastern Ice Shelf) is a critical factor, and that loss of the shelf could influence the behavior of the underlying glacier and future sea-level rise, though the shelf has already contributed to changes in how the glacier flows.[4][1]
- Projections about the full collapse of Thwaites Glacier vary by scenario, with some models suggesting substantial ice loss could occur this century and others emphasizing uncertainty about timing and regional responses, particularly as ocean conditions and ice-shelf geometry evolve.[2][3][5]
What this means
- The TEIS acts as a buttress for the fast-flowing Thwaites Glacier. Its breakdown would alter the dynamics of the glacier’s grounding line and could potentially accelerate contribution to sea level rise, but it does not automatically equate to immediate, uniform collapse of the entire glacier.[3][4]
- Ongoing research underscores that melting beneath the ice shelf is not always the primary signal of collapse; rather, internal structural changes and the propagation of cracks can drive rapid changes in the ice shelf’s integrity.[1][4]
Recent context from credible outlets
- A 2024 study summarized by science outlets argued that the Thwaites Eastern Ice Shelf is destabilizing due to internal cracks rather than basal melting alone, signaling a rapid progression toward disintegration in coming years.[1]
- Broader assessments in 2024-2025 describe potential long-term sea-level rise scenarios linked to Thwaites, including discussions of possible multi-meter contributions if large portions of West Antarctica destabilize, though these remain highly model-dependent and contingent on future climatic conditions.[2][3]

Scientists tracking Antarctica’s Thwaites Glacier found its ice shelf weakening followed an ordered pattern, driven by hidden cracks and a failing seabed anchor, raising questions about future sea level rise.
www.moneycontrol.comA recent study by a team of researchers from the International Thwaites Glacier Collaboration (ITGC) has found that the Thwaites Eastern Ice Shelf – the last floating extension of Thwaites into the ocean - is rapidly destabilising due to widening cracks, not melting from below as previously thought. Since 2016, cracks, or "rifts," in the ice shelf have been rapidly spreading and deepening, especially during the Southern Hemisphere’s spring season (Sep-Nov). These rifts have sped up the ice...

insideclimatenews.orgAbstract. Antarctic ice shelves buttress the flow of the ice sheet but are vulnerable to increased basal melting from contact with a warming ocean and increased mass loss from calving due to changing flow patterns. Channels and similar features at the bases of ice shelves have been linked to enhanced basal melting and observed to intersect the grounding zone, where the greatest melt rates are often observed. The ice shelf of Thwaites Glacier is especially vulnerable to basal melt and grounding...
