Global temperatures averaged 1.47°C above pre-industrial levels during January-September; intensifying El Niño could drive further warming into 2027. The WMO says Earth's energy imbalance has reached its highest level since monitoring began, warning that an unusually powerful El Nino could push global temperatures higher and intensify. The global average temperature from January to September 2026 was 1.47°C above pre-industrial levels (1850–1900). The past four years (2023–2026) are the four warmest on record.
