Switzerland and Italy have redrawn their Alpine border due to rapidly melting glaciers, particularly around the Matterhorn. As climate change accelerates glacier retreat, natural ridgelines that once defined the boundary between the two nations have shifted, forcing adjustments to their maps. The agreement affects popular ski areas near Plateau Rosa and Zermatt. While Switzerland has approved the change, Italy’s ratification is still pending. The situation highlights the profound impacts of global warming on Europe's landscape, as glaciers not only disappear but also reveal long-hidden remains and wreckage, symbolising the urgent need for climate action to prevent further loss.
