The impacts of global warming are felt especially in mountainous regions, where the rise in temperatures is above average, affecting both glacierized landscapes and water resources. The repercussions of these changes are manifold and varied, from retreating glaciers to an increase in the frequency and intensity of snow avalanches. A team of researchers has employed dendrochronology -– the reconstruction of past disasters as recorded in growth series of trees -– to disentangle the role of global warming in the triggering avalanches.
