CO2 Is Driving a Quiet Shift in African Savannas
Key Takeaways
- A Nature study links higher atmospheric CO2 to stronger grass growth in water-limited African savannas.
- Researchers combined 70 experiments with 32 years of field data from 533 sites in Kruger National Park.
- Grass production in the park increased 28% between 1989 and 2021, a trend the study says other factors did not fully explain.
- The findings could affect understanding of wildfire risk, wildlife habitat, and carbon cycling in major dryland ecosystems.
