This edition covers July 2024 to June 2025, the year after the 2023/24 El Niño. It was published online in Advanced Science on 1 September 2026. The CO2 growth rate was 2.62 ± 0.08 ppm yr−1, down from 3.66 ppm yr−1 during the El Niño but 6.5% above the 2013–2022 July-to-June mean. Combining bottom-up and top-down estimates, the net land sink was 1.06 ± 0.40 GtC yr−1. This was stronger than in 2023/24 but 0.49 GtC yr−1 weaker than the 2015–2022 mean, mostly because of losses in late 2024. Whether the land had recovered by early 2025 depends on the method. Ocean uptake shows no global weakening.
