Slovenia mourns loss of glacier on its highest peak after scorching summer

The final remnants of Slovenia’s Triglav glacier have melted away, with confirmation coming after snowfall earlier this month revealed bare rock where ice previously persisted. The glacier, located on the country’s highest peak, had dramatically diminished over recent decades, losing 93% of its surface area between 1983 and 2003, yet continued to survive in small patches for an additional two decades despite initial scientific concerns about its imminent demise.

Matija Zorn, director of the Anton Melik Geographical Institute, described the glacier’s loss as significant for Slovenian national identity and scientific research. He noted that while anticipating yearly ice reduction, the pace of actual melting consistently exceeded expectations. Documentation indicates the glacier covered approximately 40 hectares in the mid-1800s, shrinking to 14 hectares by 1946 when formal measurements began. The rate of decline accelerated dramatically in recent years, with measurements from core samples revealing profound changes between consecutive seasons.

The disappearance of Triglav’s glacier reflects broader Alpine conditions, where intense heatwaves intensified by carbon pollution have transformed landscapes across the region. Swiss glaciologists recently documented that nearly one-fifth of that nation’s glacial ice vanished over the last five years alone. Western Europe experienced its hottest summer on record this year, contributing to an estimated 50,000 heat-related deaths and triggering secondary environmental and economic consequences including crop failures and power generation disruptions.

Triglav holds deep cultural significance as Slovenia’s highest peak and a traditional climbing destination for the nation’s residents. While the main glacier has vanished, scientists have discovered ice deposits in caves exposed by the glacier’s retreat. A second glacier on nearby Skuta mountain has also diminished substantially, though better shading conditions suggest it may persist for several additional years, providing researchers with continued opportunities to study glacial recession and climate impacts.
