In global terms, 2025 ranked as the third-warmest year on record, following the unprecedented temperatures observed in 2023 and 2024, the latter being the warmest year on record. The global average temperature reached 14.97°C, which was 0.59°C above the 1991–2020 average and 1.47°C above the estimated 1850–1900 pre-industrial level.

While marginally cooler than 2023 (by just 0.01°C), 2025 continued a sequence of exceptionally warm years, with all of the past 11 years (2015–2025) ranking amongst the 11 warmest years on record. Although 2025 itself did not exceed the 1.5°C Paris Agreement threshold, the three-year average for 2023–2025 surpassed 1.5°C above the pre-industrial level for the first time since global temperature analyses began.
