springback mountains

Though the average hiker wouldn’t notice, the Alps and other mountain ranges have experienced a gradual growth spurt over the past century or so thanks to the melting of the glaciers atop them.

For thousands of years, the weight of these glaciers has pushed against the Earth’s surface, causing it to depress. As the glaciers melt, this weight is lifting, and the surface slowly is springing back.

Because global warming speeds up the melting of these glaciers, the mountains are rebounding faster.
