Part of the border will shift because of the glacial melt, in another sign of how much humans are changing the world by burning planet-heating fossil fuels.

The increasing rate of glacier melt has meant Switzerland's border with Italy has been redrawn — here's why, and how.

The melting of glaciers in the Alps has forced Italy and Switzerland to redraw the border that runs between them in the shadow of the Matterhorn. The frontier between the two countries has traditionally been delineated by the watershed,

Even if global warming is limited to 1.5 degrees Celsius under the 2015 Paris Agreement, the world still stands to lose around a quarter to half of all glaciers by 2100.

Global warming is causing all Alpine glaciers to recede, affecting natural boundaries and changing mountain routes.

Italy and Switzerland have been forced to redraw their border in the Alps due to melting glaciers caused by climate change. The Swiss-Italian border that runs in the shadow of the Matterhorn has usually been determined by natural boundaries created by glacier ridgelines or areas of perpetual snow.

Swizerland and Italy have redrawn part of their border as climate change is melting the glaciers that have historically marked the frontier between the two countries. The Theodul Glacier, under the famous Matterhorn mountain,

There are the expected repercussions of climate change, and then there are the more surprising ones—like two nations having to redraw their shared border due to ice melt. That's what's currently happening in Europe,
