A person who studies glaciers and their effects on landscapes and climate.
From glacier (from French 'glace' meaning ice) plus the agent suffix -ist. The term emerged in the 19th century as glaciology became a formal scientific discipline focused on ice masses.
Glacierists helped prove that ice ages actually happened—before the 1800s, people thought giant boulders in unexpected places were dropped by Noah's flood, not carved by glaciers!
