The collapse of a crucial network of Atlantic Ocean currents could push parts of the world into a deep freeze, with winter temperatures plunging to around minus 55 degrees Fahrenheit in some cities, bringing "profound climate and societal impacts," according to a new study.
There is increasing concern about the future of the Atlantic Meridional Overturning Circulation — known as the AMOC — a system of currents that works like a giant conveyor belt, pulling warm water from the Southern Hemisphere and tropics to the Northern Hemisphere, where it cools, sinks and flows back south.
Multiple studies suggest the AMOC is weakening with some projecting it could even collapse this century as global warming disrupts the balance of heat and salinity that keeps it moving. This would usher in huge global weather and climate shifts — including plunging temperatures in Europe, which relies on the AMOC for its mild climate.
What's less clear, however, is how these impacts will unfold in a world heated up by humans burning fossil fuels.

Peel Waters has submitted a new planning application for Mea Park West, a major part of the Wirral Waters regeneration scheme in the UK. The development is centred on low carbon design, featuring green infrastructure, cycle networks, and public realm improvements. Positioned as one of the country’s most ambitious projects, the expansion is expected to strengthen sustainable building practices while supporting net zero carbon ambitions and local employment. The project reflects a shift towards sustainable urban development where environmental sustainability in construction is treated as a baseline requirement rather than an add-on.
Unifi has introduced ThermaLoop, an insulation derived from REPREVE® recycled textiles, bringing the Circular Economy into the spotlight. The closed-loop takeback programme used to create the material addresses embodied carbon in materials and reduces the carbon footprint of construction through innovative resource efficiency in construction. Products like this signal a move towards low embodied carbon materials and renewable building materials, ensuring insulation plays a larger role in whole life carbon assessment and sustainable building design.
Ameresco has completed a $5.3 million energy infrastructure project at Ave Maria University. The scheme delivered solar power, HVAC upgrades, and smart metering to curb emissions and enhance energy-efficient buildings. While campus facilities are often older and energy-intensive, this project demonstrates how targeted retrofits support net zero whole life carbon objectives and long-term building lifecycle performance. Such investment highlights the role of life cycle cost analysis in planning sustainable building design and meeting expectations for carbon neutral construction.
Shifts in global data suggest major companies are scaling back on ESG marketing while increasing tangible action. More than a quarter of recent emissions reductions stem from private industry initiatives. Within construction, this underscores the importance of whole life carbon strategies, lifecycle assessment, and life cycle thinking in construction as developers focus on measurable outcomes rather than declarations. The trend advances decarbonising the built environment and reinforces the use of circular construction strategies over surface-level claims.
Materials data management is also improving, with collaborations such as Novata and S&P Global Sustainable1 aiming to simplify environmental product declarations (EPDs). Streamlined reporting frameworks aid sustainable material specification, eco-design for buildings, and life cycle thinking in construction. For large-scale investors and developers, these tools support effective circular economy in construction strategies and broaden adoption of sustainable building practices across international projects.
Growing water scarcity around the UK and globally is shaping sustainable design responses. Rainwater harvesting, efficient plumbing, and eco-friendly construction approaches are now central to building lifecycle performance. This redefines sustainable architecture and reinforces the environmental impact of construction on local ecosystems. Integrating low-impact construction techniques improves resilience while aligning projects with green building products and end-of-life reuse in construction, demonstrating how environmental sustainability in construction can mitigate resource threats.
