Venezuela Becomes First Country to Lose All Glaciers

Context

Venezuela has lost its final glacier in the Sierra Nevada de Mérida mountain range. This loss marks a significant event, making Venezuela likely the first country in modern times to lose all its glaciers.

About

  • At one time, the country was home to six glaciers, but by 2011, five had vanished, leaving only the Humboldt glacier, also called La Corona, near Pico Humboldt.
  • Initially, scientists believed the Humboldt glacier would endure for another decade. However, the glacier had melted much faster than anticipated. Its size had dwindled to less than 2 hectares, prompting its reclassification from a glacier to an ice field.
  • Unfortunately, Venezuela is not alone in facing this crisis. Indonesia's Papua island, Mexico, and Slovenia are among the next countries expected to become glacier-free.

Fact Box: About Glacier

  • A glacier is a large, perennial accumulation of crystalline ice, snow, rock, sediment, and often liquid water that originates on land and moves down slope under the influence of its own weight and gravity.
  • Glaciers are classified by their size (i.e. ice sheet, ice cap, valley glacier, cirque glacier), location, and thermal regime (i.e., polar vs. temperate). 
  • Glaciers form as snow accumulates and compresses into many layers of ice through a process called snow metamorphism.
