A significant amount of ice has melted from glaciers. This melt is affecting the planet's two major ice sheets. The process is driven largely by warmer waters. A study found that most of the melt does not come from hotter air, but from water eating away at the ice.

Further details are available from a major scientific report. The report notes that the melt is bad news for future sea level rise.

A large amount of frozen water has been lost, equivalent to a certain depth of ice across a large area.
