Global Glacier Extinction Explorer
TL;DR
The Global Glacier Extinction Explorer assesses the fate of individual glaciers, revealing that many may disappear by the mid-21st century due to climate change. Using advanced models, it provides extinction projections based on varying temperature scenarios.
✦ Why It Matters
Explore the extinction projections to inform local conservation efforts and climate action initiatives.
Key Takeaways
- Utilize the extinction projections for local climate action planning.
- Engage with community stakeholders about glacier significance.
- Incorporate glacier data into environmental impact assessments.
- Advocate for policies supporting glacier preservation initiatives.
Full Summary
Glaciers are crucial not only for sea-level rise and water resources but also for their cultural and ecological significance. The Global Glacier Extinction Explorer shifts focus from regional metrics to the extinction of individual glaciers, defining extinction as when a glacier's area falls below 0.01 km² or its volume drops below 1% of its initial value.
To analyze glacier trajectories, three models—GloGEM, OGGM, and PyGEM—were employed alongside multiple General Circulation Models under different temperature scenarios, including increases of +1.5°C to +4.0°C. The study predicts median extinction years and provides probability intervals for glacier disappearance.
Results are visualized on a map, highlighting the urgency of glacier preservation as part of the UN International Year of Glacier Preservation in 2025.
