AbstractAccurate national terrestrial net ecosystem exchange estimates are crucial for the global stocktake. Net ecosystem exchange estimates from different inversion models vary greatly at national scale, and the relative impacts of prior fluxes and observations on these inversions remain unclear.

AbstractThe Paris Agreement mandates that signatory countries enhance the transparency of their national greenhouse gas inventories. China’s inventories have reported substantial forest carbon gains using ground-based forest plot measurements, but independent satellite-based support for such inventories is lacking and the contributions from human management and anthropogenic environmental changes (atmospheric CO2 growth, climate change and nitrogen deposition) are unknown.

AbstractMicrobial carbon use efficiency (CUE) affects the fate and storage of carbon in terrestrial ecosystems, but its global importance remains uncertain. Accurately modeling and predicting CUE on a global scale is challenging due to inconsistencies in measurement techniques and the complex interactions of climatic, edaphic, and biological factors across scales.

AbstractTropical terrestrial ecosystems play an important role in modulating the global carbon balance. However, the complex dynamics and factors controlling tropical aboveground live biomass carbon (AGC) are not fully understood. Here, using remotely sensed observations, we find a moderate net AGC sink of 0.21 ± 0.06 PgC yr−1 throughout the global tropics from 2010 to 2020. This arises from a gross loss of −1.79 PgC yr−1 offset by a marked gain of 2.01 ± 0.06 PgC yr−1.

Correction to: Nature Communications https://doi.org/10.1038/s41467-024-47143-5, published online 11 April 2024The original version of this Article contained an error in Fig. 1, which did not represent fully updated data. This has been corrected in both the PDF and HTML versions of the Article. The original version of the Supplementary Information associated with this Article had identical information presented in Tables S2 and S3, which has been corrected to remove the redundant information.

AbstractThe northern terrestrial biomes are being remarkably altered by climate change. Higher springtime temperature induces the earlier greening of vegetation, which may further influence ecosystem functions during the subsequent season. However, the response of summer net ecosystem productivity to spring vegetation greenness and phenology changes has not yet been quantified.

AbstractPlants with the C4 photosynthesis pathway typically respond to climate change differently from more common C3-type plants, due to their distinct anatomical and biochemical characteristics. These different responses are expected to drive changes in global C4 and C3 vegetation distributions. However, current C4 vegetation distribution models may not predict this response as they do not capture multiple interacting factors and often lack observational constraints.
