Where on Earth are temperate glaciers located?
A temperate glacier (as opposed to a polar glacier) is a glacier that’s essentially at the melting point, so liquid water coexists with glacier ice. A small change in temperature can have a major impact on temperate glacier melting, area, and volume. Temperate glaciers exist on the continents of North America, South America, Europe, Africa, and Asia, on both islands of New Zealand, and on the island of Irian Jaya. Additionally, some of the glaciers of the Antarctic Peninsula and some of Greenland’s southern outlet glaciers are temperate.
