It is worth a reminder that each year we revised the carbon budget in all years, not just the last year
www.carbonbrief.org/analysis-fos...
This year we had a rather big adjustment in land-use change emissions, including the change in carbon density due to CO2 fertilisation, etc.

The 2025 update of the Global Carbon Budget is out.
While fossil CO2 emissions rise again and carbon sinks are weakened by climate change, deforestation emissions are down and many countries decarbonise their energy.
No global emissions peak yet though.

The world’s carbon emissions continue to rise. But 35 countries show progress in cutting carbon
In 2025 the world has fallen short, again, of peaking and reducing its fossil fuel use. But there are many countries on a path to greener energy.

Still no peak. Emissions are projected to increase by 1.1% in 2025, reaching 38.1 GtCO2. An all time high.

New assessment on the biophysical potential of forestation to sequester carbon. As expected, we found just a fraction of what other assessments found, because we considered the obvious no-nos, such as risk to biodiversity, excess water use, and regional warming.

A new study, led by Matthias Cuntz and our dearest late Vanessa Haverd, shows beautifully how the increase of the seasonal variation in atmospheric CO2 in the Northern Hemisphere over the past 40 years can only be explained by an increase in the CO2 uptake by plants.
