For months, a gargantuan iceberg has been slowly spinning in one spot in the Southern Ocean — and it could continue to stay trapped in this vortex for quite some time, experts say.
As the world’s largest iceberg, the colossus A23a is of great interest to scientists, who have closely monitored the frozen block since it calved from Antarctica’s Filchner-Ronne ice shelf in 1986.
Now, the iceberg’s fate is unclear as it remains stuck as a result of a rare set of circumstances that scientists say is unprecedented.
The roughly 3,672-square-kilometer (1,418-square-mile) chunk of ice — slightly bigger than Rhode Island and more than twice the size of the city of London — drifted over a seamount and got stuck in a phenomenon known as a Taylor column, a spinning vortex of water caused by ocean currents hitting the underwater mountain.

The UK’s sustainable construction sector is shifting from policy ambition to tangible decarbonisation, with major infrastructure and industrial players adopting measurable strategies to reduce whole life carbon across assets. The progress of Sizewell C’s nuclear power project, reaching financial close, highlights the integration of low carbon design within national energy infrastructure and reinforces the role of net zero whole life carbon objectives within long‑term energy security. The inclusion of nuclear energy within the UK’s net zero carbon strategy underlines a move toward environmental sustainability in construction that balances embodied carbon performance with broader lifecycle assessment principles.
The Environmental Services Association’s new guidance connecting Energy‑from‑Waste facilities to urban heat networks signals a critical evolution in circular economy thinking. By recasting waste as a resource for district heating, the approach channels circular economy in construction strategies and manages the carbon footprint of construction through controlled use of residual energy. This shift illustrates how sustainable building design can incorporate end‑of‑life reuse in construction and enhance resource efficiency without compromising low carbon building integrity.
Sunbelt Rentals’ full electrification of its Milton Keynes depot represents the operational embodiment of whole life carbon assessment within industrial infrastructure. Electrified depots limit Scope 1 and 2 emissions, advance eco‑friendly construction practices, and demonstrate how sustainable building practices apply to the equipment supply chain. These advances support lifecycle assessment integration and foster demonstrable reductions in embodied carbon in materials and operational energy use—critical metrics for achieving BREEAM V7 and high‑level environmental product declarations (EPDs).
Investor calls for policy stability before the budget underscore the market’s readiness for sustained investment in green construction. Financial alignment around low embodied carbon materials, circular construction strategies, and carbon neutral construction signals a decisive shift toward scalable solutions addressing the environmental impact of construction. The sector’s increasing emphasis on life cycle cost, sustainable material specification, and building lifecycle performance demonstrates that 2024 marks a phase of deployment rather than demonstration for sustainable construction and sustainable urban development, advancing the goal of truly net zero carbon buildings.
