How to Use This Calculator
- Enter the Base retreat rate (m/yr) from historical terminus measurements for your glacier.
- Set the Temperature anomaly (°C) — use local meteorological records relative to a baseline period.
- Enter the current Glacier length (m) from terminus to head, and the Mean elevation (m).
- Set the Observation period (years) over which you want to project retreat.
- Read the Effective retreat rate (m/yr) and Total retreat (m), then check Years to disappear to assess long-term viability.
