What is a glacier?
A glacier is simply any perennial body of ice that flows under its own weight due to gravity.
There are generally two parts:
1. The zone of accumulation: where ice is added (usually by snow turning into ice) and
2. The zone of ablation: where ice is melted, calved, or sublimated away
If there is more ice added to the glacier than is taken away, then the glacier will advance.
However, if there is more ice removed from the glacier than is added, the glacier will retreat.
Currently, almost every single glacier worldwide is in retreat
since around the start of the industrial revolution, due to anthropogenic warming.
