  • Plant nitrogen availability constrains ecosystem productivity, yet its decadal-scale dynamics remain unclear. Using global foliar δ¹⁵N data (1980–2020) and machine learning, this study suggests that nitrogen availability initially declined and then stabilized, as the dominant driver shifted from atmospheric CO2 to precipitation.

  • Global vegetation growth peaks have been increasing over recent decades, but grasslands are highly sensitive to climate, and it is unclear whether this upward trend can be sustained. This study shows that over the past four decades, decadal droughts have temporarily disrupted this global increase in grassland peak productivity.

  • It is unclear whether rapid global change will lead to unexpected trait combinations. In this global meta-analysis on vascular plants, Cui et al. show that, although within-species responses do not always follow the leaf economic spectrum, the slopes of interspecific trait relationships are robust to rapid environmental change.

  • Combining two global datasets, the authors show that peak vegetation growth has been increasing linearly for the past 30 years, with similar proportions of NDVI variation attributable to expanding croplands, rising CO2 and intensifying nitrogen deposition.
