An unusually warm winter in Canada has delayed the opening of a crucial 400-kilometer ice road to remote Arctic diamond mines, causing ripple effects across the global diamond industry.
The ice road, known as the Winter Road, is rebuilt annually and serves as the main supply route for mining giants Rio Tinto, Burgundy Mines, and De Beers to access their diamond mines in the Arctic region. Typically accessible only by air for ten months of the year, these mines rely on the ice road during the harsh winter months to transport essential goods and equipment.
This year, the Winter Road opened two weeks late in mid-February due to unusually warm temperatures, disrupting the movement of goods along a route that spans over 64 frozen lakes. The delay is the longest in recent years, highlighting the growing challenges posed by climate change.
“Climate change, combined with the natural El Niño climate pattern, has pushed the world into record heat territory in 2023,” said Tom Hoefer, senior advisor to the Northwest Territories (NWT) and Nunavut Chamber of Mines. The capital of the NWT, Yellowknife, recorded its warmest winter days in a decade, with temperatures reaching zero degrees Celsius in December and minus 8.7 degrees Celsius in February.
While diamond production remains unaffected for now, the delay underscores the vulnerabilities of mining operations in the face of a changing climate. The Arctic mines contribute significantly to Canada being the world’s third-largest diamond producer, and disruptions could have global market implications, including potential effects on Asian diamond markets where demand remains high.
Moreover, the delays highlight the infrastructure challenges facing the NWT and Nunavut, regions positioning themselves as the next frontiers in exploring critical metals such as rare earth elements, cobalt, and lithium—essential for the transition to a greener future. Efficient transportation routes are vital for these remote areas to realize their potential in supplying materials critical to global industries, including those in Asia.
Local companies and Indigenous corporations are concerned about the shortening of the ice road season. “When you’re nibbling away on both sides of that, you start to create a very short season,” said Paul Gruner, CEO of the Indigenous corporation Tlicho Investment Corp & Group of Companies, referring to the warm winter at the start and the risk of an early spring.
Engineers have attempted to mitigate the warmth by creating artificial ice using giant sprinklers to spray water high into the air, which cools and forms a thick layer of ice upon falling. However, such measures may not be sustainable long-term solutions as climate patterns continue to shift.
As global temperatures rise, industries and communities in the Arctic and beyond must adapt to new realities. The situation in Canada’s Arctic serves as a stark reminder of the interconnectedness of global supply chains and the far-reaching impacts of climate change—issues that resonate deeply with stakeholders worldwide, including those in Asia.
