Marmolada: The Highest Glacier in the Dolomites Is Disappearing
The Marmolada Glacier, the largest glacier in the Dolomites, is losing ice at an ever-increasing rate. Recent measurements indicate that by 2026, the glacier front will have retreated an average of about 23 meters—nearly three times as much as in the previous year. In just one year, the glacier’s area shrank from about 92 to 83 hectares.
As a result, about nine hectares of glacier ice were lost within a year—an area roughly the size of twelve soccer fields.
The change is particularly pronounced in certain sections. On the western front, a retreat of up to 120 meters was recorded over a two-year period. The glacier front is now located at an elevation of over 2,900 meters.
An Exceptionally Warm Summer
A major contributing factor is the persistent heat at high altitudes. According to recent studies, the summer of 2026 was the hottest on record in the higher elevations of the Dolomites since measurements began in 1991.
High temperatures do more than just accelerate surface ice melt. Meltwater can seep deep into the glacier through crevasses and affect the stability of individual sections of ice.
In August, crevasses filled with meltwater were once again observed on the Marmolada above the area where a massive ice and rock avalanche occurred in 2022. Eleven people lost their lives in that incident.
This does not mean that another major ice break-off is imminent. Such a prediction cannot be derived from the observations. However, they do show how rapidly conditions on the glacier are changing and why monitoring and risk assessment are becoming increasingly important.
It's not just the Marmolada that's changing
This trend is typical of the glaciers in the Alps. Rising temperatures are pushing the snow line higher, shortening the period during which the glaciers are protected by a snow cover, and leaving ever-larger areas of glacial ice unprotected during the summer.
This, in turn, is changing the high-mountain region itself. Where ice is disappearing, rock faces and slopes can become more unstable. At the same time, the water cycle, landscape, and alpine ecosystems are changing.
Facts & Figures
* The Marmolada glacier front is projected to retreat an average of about 23 meters by 2026
* It retreated about 8 meters in 2025
* Glacier area decreased from approximately 92 to 83 hectares within one year
* Approximately 9 hectares of ice area lost in one year
* Up to 120 meters of retreat on the western front within two years
* Glacier front now at an elevation of over 2,900 meters
* 11 fatalities in the ice and rock avalanche in July 2022
Conclusio
The Marmolada illustrates just how quickly climate change is altering the appearance of the Alps. Glacier retreat, which has been observable over decades, is increasingly becoming a process that transforms entire landscapes within just a few years.
If summers like that of 2026 were to recur, there might be hardly anything left of the Marmolada Glacier—which still exists today—within just a few decades. At the same time, new risks are emerging in the high mountains, and the tourism industry, mountain rescue services, and government agencies must adapt to them.
The retreat of the Marmolada is therefore more than just the loss of ice. It is a visible sign of how rapidly conditions are changing in Europe's high mountains
