Why the 2022 Italian snow drought matters to you
2022 was a particularly poor snow season across the Italian Alps, with estimated anomalies in Snow Water Equivalent compared to the last 12 years well below -75% at places. Photo credit: S3M Italy by CIMA Research Foundation, background layer is from the ESRI Satellite Theme.

June 2022: I was discussing the ongoing drought with my family over lunch, when my dad pointed to me and summarized things as follows: “You know, less snow in winter means less water in summer!” I almost choked … what? Not only was it the first time I realized my family had been listening to my scientific anecdotes for years, but I also had concrete evidence now that snow was entering public ...[Read More]

When you hear of Chilean glaciers, you probably think about the large glaciers of Patagonia. However, glaciers can be found further north in Chile as well (see this previous post). While the melting of the Patagonian glaciers mainly affects the global human population by contributing to sea level rise, the retreat of glaciers in central Chile affects the local human population directly in terms of ...[Read More]

As the world searches for practical innovations that can mitigate the impact of climate change, traditional methods of environmental management can offer inspiration. In Hindu Kush and Karakoram region, local people have been growing, or grafting, glaciers for at least 100 years. Legend has it that artificial glaciers were grown in mountain passes as early as the twelfth century to block the advan ...[Read More]
