Scientists have looked back in time to reconstruct the past life of Antarctica’s “Doomsday Glacier” — nicknamed because its collapse could cause catastrophic sea level rise.
Experts knew it had been losing ice at an accelerating rate since the 1970s, but because satellite data only goes back a few decades, they didn’t know exactly when significant melting began. Now there is an answer to this question, according to a study published in the journal Proceedings of the National Academy of Sciences.
By analyzing marine sediment cores extracted from beneath the ocean floor, researchers found the glacier began to significantly retreat in the 1940s, likely kicked off by a very strong El Niño event. Since then, the glacier has been unable to recover.

The UK construction sector is entering a decisive phase of sustainable construction focused on measurable carbon reduction rather than symbolic gestures. The launch of the UK’s first commercial‑scale carbon capture and storage facilities in the East Coast Cluster, operated by pX Group, marks significant progress in decarbonising the built environment. These links between energy‑intensive industries and new CO₂ transport and storage systems are reshaping the embodied carbon profile of essential materials such as cement and steel, critical to sustainable building design and eco‑friendly construction. The integration of low embodied carbon materials forms a foundation for the adoption of whole life carbon assessment methods and lifecycle assessment strategies now demanded across the supply chain.
Concrete innovation is accelerating as “green concrete” becomes a viable element of low carbon design. Manufacturers are scaling from trials to full delivery. JCB’s move to provide a 100% biodiesel option for tracked excavators demonstrates practical progress toward net zero carbon buildings and carbon neutral construction. Effective reductions depend on verified renewable building materials and traceable biofuels, requiring stricter sustainable material specification and transparent environmental product declarations (EPDs). Verified sourcing and supply are vital to minimising the carbon footprint of construction and improving resource efficiency in construction.
Across projects, whole life carbon thinking is now inseparable from life cycle cost analysis. Intensifying climate conditions—from escalating floods to drought stress—demand resilient, energy‑efficient buildings and green infrastructure designed using eco‑design for buildings principles. Resilience and sustainability are no longer optional performance indicators but integral to building lifecycle performance and sustainable building practices. The industry response is to secure supply from emerging low carbon construction materials clusters, adopt verified fuels and plant emissions data, and embed circular construction strategies.
The momentum reflects a commitment to environmental sustainability in construction, combining circular economy in construction models with frameworks such as BREEAM V7 to achieve net zero whole life carbon outcomes. Through transparent lifecycle assessment and life cycle thinking in construction, every project can demonstrate measurable progress in carbon footprint reduction and deliver the economic and environmental returns driving the transition to sustainable urban development.
