Executive Summary
A US-UK team built a real-time model that predicts September Arctic sea ice months ahead, improving planning for a rapidly warming Arctic.
- Researchers built a real-time model to forecast September Arctic sea ice extent up to four months ahead
- The model combines climate memory, seasonal cycles, and fast-changing weather on multiple timescales
- It was tested with daily sea ice records from the National Snow and Ice Data Center dating to 1978
- Forecasts were checked against real-time September 2024 data and historical September cases
- The method outperformed existing approaches for one- to four-month-ahead sea ice predictions
- The work highlights value for Indigenous Arctic communities and activities like fishing, drilling, and tourism
- Planned upgrades include air temperature and sea level pressure to capture rapid variability
Quick Facts
- What: Real-time model forecasts September Arctic sea ice months ahead
- Where: Across the pan-Arctic using long-term sea ice records
- Why: Better forecasts can support Arctic planning as sea ice declines
- Who: Scientists from the United States and United Kingdom
- When: Announced in February 2026 after testing September 2024 data
