The Disappearing Snow of the Alps: A Century of Climate Change Unveiled

Snowfall across the Alps has declined by an alarming 34% over the past century, according to groundbreaking research led by scientists at the Eurac Research Centre in Italy. This comprehensive study is among the first to analyze the entirety of the Alpine region over a long period, shedding light on the profound impact of climate change on Europe’s highest mountain range.

A Century-Long Decline in Snowfall

The study tracks snowfall trends between 1920 and 2020, highlighting a stark decrease, particularly on the southwestern slopes, where the loss reaches almost 50%. The northern Alps fared slightly better, with a 23% decline. The shift is most pronounced below 2,000 meters, where warmer temperatures are converting snow into rain, exacerbating the decline.

Lead author Michele Bozzoli, an environmental meteorologist, emphasizes the turning point in 1980, correlating the sharp decrease in snow with a significant rise in temperatures. “Climate change is dramatically altering the face of the Alps,” Bozzoli explains.

How the Data Was Collected

To create a detailed picture of the Alps over a century, researchers combined modern weather station data with historical, handwritten records meticulously maintained by observers. This unique approach involved collaboration with meteorological offices, environmental agencies, and volunteer groups across the Alpine region.

Why the Decline Matters

The diminishing snow has far-reaching consequences. Snow serves as a crucial water reservoir, slowly melting in spring to sustain rivers, streams, and water reserves. The decline also threatens the region’s winter tourism, a key economic driver.

“Without snow, skiing and related activities suffer, directly impacting local economies,” says Bozzoli. The reflective properties of snow, which influence regional climate patterns, are also diminishing, creating a feedback loop that accelerates warming.

A Call for Action

The study underscores the urgent need for policies that address water management and climate change in the Alpine region. With temperatures continuing to rise due to greenhouse gas emissions, protecting the Alps and its resources is more critical than ever.
