And of all that change, maybe no other thing is as mercurial as Earth's ice. to glaciers, Earth's frozen water moves and changes rapidly, particularly due to climate change.
For instance, the images above show the rapid retreat of glaciers from Alaska to the Himalayas, visual confirmation of what scientists have known for years: .
