📢Global Carbon Budget 2025📢
Fossil CO2 emissions continue to rise in 2025 while the terrestrial carbon sink recovers to pre-El Niño strength.
The key findings are covered in two reports this year:
* ESSDD (preprint): essd.copernicus.org/preprints/es...

Climate change made 213 historical heatwaves reported over 2000–2023 more likely and more intense, to which each of the 180 carbon majors (fossil fuel and cement producers) substantially contributed.
