Key Takeaways
- Arctic ice loss is thawing rapidly, opening up significant shortcuts in global trade routes.
- Over the past decade, shipping across the Arctic has increased 37%, with the Greenland ice sheet shrinking by 129 billion metric tons in 2025 alone.
Not only does the Arctic hold significant oil and rare earth resources, thawing ice means that shipping routes can be reduced drastically.
Since 1980, the Arctic’s minimal ice extent, its smallest point, has shrunk by 39%. At the same time, the Arctic is a strategic priority for Russia, both for freight transport and military security. More recently, President Trump has argued that Greenland—a territory he has threatened to acquire—is critical to U.S. security.

The Rise of Arctic Shipping As Ice Thaws
Over the last decade, Arctic shipping has increased 37%, with 1,781 unique ships sailing a combined 12.7 million nautical miles in 2024.
Ship traffic is increasing as Arctic ice is thawing at a notable pace. For perspective, the loss in minimal ice extent between 1980 and 2025 is greater than the size of India’s land area.
Below, we show the annual minimum Arctic ice extent over the past several decades.

Among the region’s key shipping corridors are the Northern Sea Route and the Northwest Passage.
The Northern Sea Route, in particular, is central to Russia’s strategic ambitions. In 2025, the first vessel completed a China–Europe transit along the route in roughly 20 days, covering 7,850 nautical miles. By comparison, the southern route via the Suez Canal takes about 27 days and spans 11,167 nautical miles.
Looking ahead, the even shorter Transpolar Route—cutting directly across the North Pole—could become viable as early as 2059. The Arctic is warming at roughly four times the global average, accelerating ice melt and extending navigable seasons.
If realized, the Transpolar Route would further reduce shipping distances and costs, while significantly increasing the Arctic’s geopolitical and economic importance.
