Climate changeEuropean forest carbon sink shrank in 2020-2023 across satellite, inventory and inversion data
Satellite data, national inventories and atmospheric inversions all show Europe's forest carbon sink weakening, mainly in central and boreal Europe, but they disagree on how large the carbon losses are.

Climate changeHuman-induced warming reached 1.37 °C in 2025, rising 0.27 °C per decade
The fourth annual indicator update finds human-induced warming at 1.37 °C in 2025, rising at 0.27 °C per decade, with emissions at a record high but no longer growing rapidly.

Climate changeISIMIP3b supplies CMIP6-based climate inputs and experiments for impact models
ISIMIP3b gives impact modellers a common set of bias-adjusted climate, cyclone, ocean and CO2 inputs from five CMIP6 models, with historical and future experiments that hold human forcing fixed.

Climate change2024 saw record CO2 growth and a large budget gap as fossil emissions rose 1.1 %
Fossil emissions hit a new high in 2024 and are projected to rise again in 2025, while 2024's record atmospheric CO2 growth left the carbon budget about 1.7 GtC out of balance.
