Technically, these glaciers aren’t “melting” after all. They’re receding — and they’re not receding because they’re melting. A glacier is a river of ice that flows just like any other river. And they are receding because the ice fields that are the sources of these “rivers” aren’t getting enough precipitation to maintain the volume of ice flow in the glaciers.

Some of the most notable glaciers in the world are fed by ice fields that get so little precipitation that they’re classified as deserts.

Correct. There was more precipitation during the Ice Age compared to now. That allowed for large savannas to grow in the Southern Plains. All sorts of large bison, mammoths, sloths, tigers, etc. that are no longer around due to the lack of habitat.
