As part of the GCP-Regional Carbon Cycle Assessment and Processes-2, we recently published the Australasia's CH4 and N2O Budgets. The carbon budget was published in 2023, both papers, led by Yohanna Villalobos and a great team of collaborators.

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.

There is so much discussion about TIPPING POINTS, yet there are so few current large-scale examples that have been demonstrated quantitatively.
Xiaojun Li et al show a remarkable shift from accumulating carbon in living biomass in the northern temperate regions to losing carbon since 2016.

Among many improvements and updates, the new budget has:
1. Reduced double-counting of inland waters (rivers, lakes, wetlands, reservoirs...)
2. A first-of-its-kind partition between anthropogenic and natural emissions from inland waters,
3. Increased use of satellite methane data
