Scientists report September 2025 as the third-warmest on record, measuring 1.47°C above pre-industrial levels. The Copernicus Climate Change Service data shows persistent high temperatures continuing the trend of recent years, with 2025 expected to follow 2024 and 2023 as the third-hottest year on record. This ongoing warming trend reflects the continuing influence of greenhouse gas accumulation as nations prepare for UN climate negotiations.
