Briefings

A 2026 study reveals that despite glaciers ending in lakes, oceans, or ice shelves representing only 3.2% of the global glacier population, they account for over half of total ice loss. Between 2000 and 2019, these specific glaciers lost 134 billion metric tons annually, a rate significantly higher than the rest of the glacier system.

Key points

• Glaciers terminating in lakes, oceans, or ice shelves constitute 3.2% of the world's total glacier area.
• These specific glaciers lost 134 billion metric tons of ice annually between 2000 and 2019, representing over 50% of all glacier ice loss.

Context

This finding highlights a critical discrepancy where a small fraction of glaciers are responsible for the majority of ice loss, suggesting rapid melting in specific coastal and lake environments.

Limitations

Data covers the period 2000-2019 only; the study does not provide future projections or identify specific drivers for the observed loss rates.
