# Geoengineered ice arches proposed to hold Arctic sea ice in place

Researchers have proposed constructing underwater "ice arches" to physically stabilize and preserve Arctic sea ice. The idea is still in early stages, with no field tests. If viable, it could offer a new geoengineering tool against sea-ice loss, though feasibility and ecological impacts remain uncertain.
