PM2.5 Pollution May Be Weakening Plants’ Carbon Uptake
Key Takeaways
- Researchers found PM2.5 pollution reduces plant water-use efficiency across multiple global datasets.
- The effect is driven mainly by suppressed photosynthesis rather than increased water loss.
- Current ecosystem models may be missing the impact because they omit aerosol processes.
