Switzerland and Italy tweaked their mountain border under the Matterhorn peak as climate change in the Alps is melting the glaciers that have historically marked the frontier between the two countries.

“Significant sections of the border are defined by the watershed or the ridge lines of glaciers, firn or perpetual snow,” the Swiss government said Friday in a statementBloomberg Terminal. “These formations are changing due to the melting of glaciers.”
