Thick Arctic Sea Ice Disrupts Northwest Passage Shipping Plans

New research reveals that melting sea ice is releasing older, thicker ice, shortening the navigable season in key sections.

The navigable season in the Northwest Passage has decreased significantly between 2007 and 2021.
Thicker, centuries-old ice from the Arctic Ocean is creating choke points along the passage.
Communities relying on maritime shipments face higher costs and logistical challenges.
The study used real ship traffic data, contrasting previous models that predicted easier navigation.
Future Arctic shipping routes may require substantial investment in icebreakers and specialized vessels.
