How to Use This Calculator
- Enter current mean annual air temperature (°C), projected warming (°C), and current thaw season length (days).
- Set mean thaw temperature (°C), select soil type, and enter permafrost area (km²).
- Set carbon density (kg C/m³) and time horizon (years).
- Review Projected Active Layer Thickness (m), Carbon Released (tonnes CO₂e), and Thaw Rate.
