the hills are alive! (2)

As reported in Geophysical Research Letters, one effect of global warming is that mountains can get taller. The weight of ice held in glaciers can contribute to the depression of the earth’s crust into the viscous mantle; as the glaciers shrink the effect of that depression is reduced, and mountain ranges gradually uplift.

Glaciers in the Alps have been shrinking since the end of the last mini ice age, but evidence suggests the rate of shrinkage is increasing due to anthropogenic climate change, with knock on effects on the rate of mountain uplift.
