Data includedThe 2025 synthesis covers plans recorded by 30 September, representing about 30% of 2019 global emissions excluding LULUCF.
Data includedEurope’s warmest year on record was 2024. Flooding killed at least 335 people and affected an estimated 413,000.
Data includedAnnual greenhouse-gas emissions need to fall 42% by 2030 and 57% by 2035 from 2019 levels.
Data includedSurface temperature was 1.55 ± 0.13°C above 1850–1900. WMO cautioned against conflating a single year with the long-term threshold.
Data includedAnnual surface temperature exceeded the 1991–2020 average by about 0.86°C. North Africa’s anomaly was 1.28°C.
Data includedAsia’s mean temperature was about 1.04°C above 1991–2020. Record ranking varies by dataset.
