The World Meteorological Organization’s State of the Climate Update, released at COP31 on Nov. 9, puts the January–September 2026 global temperature average 1.47°C (±0.13°C) above the 1850–1900 baseline. The agency says 2023–2026 are on course to be the four warmest years in the record.

WMO reports that Earth’s energy imbalance reached a record in 2025, with preliminary observations showing another high in January–July 2026. The figures are provisional and the report cautions that its temperature assessment does not capture the full effects of the developing El Niño.
