The melting of Earth’s polar ice is warping the planet’s crust.
Ice from the fracture zone of a glacier crashes into the ocean in Greenland.
Scientists knew that when ice disappears, the crust underneath changes.
The crust beneath, no longer under all that weight, slowly backed up.
This is called isostatic rebound.
In some high-latitude regions, the ground is rebounding from the retreat of the ice sheets during the end of the last ice age.
The polar regions are losing ice at an increasing rate due to climate change.
From 2000 to 2010, ice loss from Antarctica, Greenland and mountain glaciers increased 60% compared with the ice loss between 1990 and 2000.
According to a paper published in 2020 in The Cryosphere.
This melt is affecting the shape of the crust.
It changes both vertically and horizontally.
Sophie Coulson, the researcher with her team, found that there are tiny particles which move within the crystal of ice.
