Arctic 'Atlantification' accelerates, reshaping great-power competition

The Arctic is warming at least four times faster than the global average, with the 'Atlantification' process—where warmer Atlantic waters intrude into the Arctic Ocean—accelerating sea-ice loss and opening new shipping routes and resource access. This environmental shift is intensifying strategic competition among major powers (US, Russia, China) for influence, military presence, and economic control in the region. The pace and geopolitical consequences remain uncertain, but the trend is clear and has global implications.
