Arctic

Greenland is taking on a growing role as the US military's forward listening post in the Arctic, as Washington monitors Chinese activity in the region. The island's strategic position between North America and Europe makes it key to early-warning radar and missile defence. Coverage notes rising US-China rivalry is pushing both countries to compete for influence over the Arctic, and over Greenland itself.

The leaders of the United States, Denmark and Greenland have signed a new security agreement concerning Greenland, according to a breaking report circulating widely online. The deal would touch on the Arctic island's defence arrangements, an area of heightened attention given Greenland's strategic location and ongoing debate over its political future and US interest in the territory.

Korean shipbuilders are pushing to develop technology that allows ships to navigate safely through Arctic ice, as melting sea ice opens new shipping routes and access to energy resources. The race positions South Korea's major yards against international rivals to supply ice-class vessels and equipment for polar shipping, a market expected to grow as Arctic traffic increases.

A robotic submarine deployed beneath Antarctic ice mapped unusual structures on the seafloor before disappearing without a trace. The lost vehicle reportedly recorded strange formations under the ice shelf before contact was cut off. The disappearance has drawn attention because the sub was gathering rare data from one of the least explored environments on Earth, raising questions about what it found and why contact was lost.
