Arctic infrastructure was built on frozen ground – drones and digital twins can help spot the permafrost thaw coming

A civil engineer describes how thawing permafrost in places like Wainwright and Utqiaġvik, Alaska, is undermining roads, buildings and pipelines as Arctic temperatures rise two to three times faster than the global average. A 2025 estimate put potential building and road damage in Alaska at $37 billion to $51 billion, and a 2023-2024 bluff collapse in Utqiaġvik brought eroding coastline dangerously close to existing structures.

To find hidden weak spots without drilling expensive borehole grids, researchers are using drone-mounted electromagnetic sensors that detect differences between salty unfrozen ground and ice-rich frozen soil, paired with computer models called digital twins that combine heat-transfer physics with real-time sensor data. A 2026 study modeling Alaska's Arctic Coastal Plain projects that under high-emissions warming, risk to infrastructure stays under 10% through mid-century but climbs sharply after, reaching roughly 80% of buildings, 60% of roads and 90% of pipelines at risk by the 2090s.
