- Unit
- September global temperature anomaly · °C relative to 1850–1900
- Period
- 1980–2026 · 47 September observations
- Source
- ERA5 · Copernicus Climate Change Service (C3S) / ECMWF. 47 global September surface-air-temperature anomalies, 1980–2026, in °C relative to 1850–1900 (ano_pi), from the primary CSV, updated 3 October 2026; bulletin 12 October 2026. Original data precision is preserved; the complete project displays two decimals. These are September monthly anomalies, not annual averages, a 1991–2020 baseline, cumulative values or projections. One month above 1.5°C does not establish a breach of the Paris Agreement’s long-term temperature limit. Animation is visual interpolation, not extra observations or evidence of causes. Primary dataset, methods and bulletin links are in the source notes.
