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

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.

Fast-melting glaciers along the Matterhorn have led to Switzerland and Italy redrawing part of the border they share.

Melting glaciers changed the topography of a roughly 330-foot-long segment of the border between Italy and Switzerland.

Italy and Switzerland have redrawn their shared border in the Alps, a decision compelled by climate change. Historically, the two European countries have used glaciers in the shadow of the Matterhorn mountain peak as their frontiers, but the glaciers are rapidly shrinking due to climate change.

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,

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,
