High summer temperatures caused record melting of the Norwegian archipelago’s glaciers. 🧊
Home to some of Earth’s northernmost glaciers, Svalbard is one of the fastest-warming places on the planet. In late July and early August 2024, temperatures hovered around 4 degrees Celsius (7 degrees Fahrenheit) above average for this part of the Arctic Circle. Its ice caps broke their all-time record for daily surface melt on July 23.
#Landsat captured these images of Nordaustlandet—the second largest island in the archipelago—on August 9 as water and sediment drained off the coast. Sediment is likely causing the swirls of color in the water surrounding the island.
Image Descriptions:
1: Satellite image of Nordaustlandet, the second largest island in the Svalbard archipelago. The island is mostly covered in a blanket of white ice. Melting has exposed a brown landscape along the coast. Swirls of brown and teal fade from the coast into the dark blue ocean.

Ocean governance reforms now carry direct consequences for sustainable construction and environmental sustainability in construction. The UN High Seas Treaty and proposed protections for the Antarctic Peninsula introduce stricter environmental impact assessments for offshore and coastal developments, signalling an era of detailed whole life carbon assessment in marine-related infrastructure. Developers of subsea cables, interconnectors, and COâ‚‚ pipelines will contend with extended consenting processes and biodiversity restrictions that influence material selection, eco-friendly construction practices, and low carbon design decisions across multiple jurisdictions. The evolution of marine spatial planning aligns with circular economy in construction principles, recognising supply-chain carbon exposure as both a design and compliance issue.
Trade policy disruption poses further challenges to sustainable building design. Prospective tariffs on low-carbon materials—such as green building materials, steel, engineered timber, and heat-pump components—threaten project timelines and budgets. Anticipated responses include regional procurement strategies, adoption of sustainable material specification, and more rigorous evaluation of embodied carbon in materials and life cycle cost performance. Demands for verifiable environmental product declarations (EPDs) and building lifecycle performance metrics are expected to rise as clients seek transparency for carbon neutral construction targets.
Climate volatility is reshaping low-impact construction strategies, particularly in flood-prone and mountainous regions. Designers must adopt adaptive lifecycle assessment frameworks that prioritise redundancy, attenuation, and slope stability. These approaches support net zero whole life carbon goals and reduce the carbon footprint of construction, reinforcing resilience and resource efficiency in construction.
The policy debate on decarbonisation is shifting toward measurable outcomes. Governments are preparing performance-linked procurement and finance mechanisms that embed whole life carbon benchmarks into material supply chains. The accelerating move toward net zero carbon buildings, green construction, and BREEAM V7 standards signals the transition from intent to implementation. Markets for low embodied carbon materials and circular construction strategies are scaling at pace, defining a new baseline for sustainable building practices and comprehensive whole life carbon accountability across the global built environment.
