Nutrient enrichment and herbivore exclusion disrupt the climate-driven balance between C3 and C4 plants in grasslands

The paper shows that nutrient enrichment, especially with nitrogen and phosphorus, reduces C4 plant cover in grasslands, disrupting climate-driven C3-C4 balance globally.

Local nutrient addition drives plant biodiversity losses but not biotic homogenization in global grasslands

This study shows nutrient addition reduces plant diversity at local and larger scales equally, without causing biotic homogenization in global grasslands.

A large global soil carbon sink informed by repeated soil samplings

The paper quantifies a global soil organic carbon sink of 1.83 petagrams per year from 1992 to 2020, driven by extratropical and boreal ecosystems, highlighting the importance of soil conservation for climate mitigation.
