Short summary
We studied how airborne particles like smoke affect a pristine Amazon rainforest. Using long-term data, we found that high aerosol pollution reduces the heat and water vapor released by the forest, causing a cooling effect. Surprisingly, it also substantially boosts the forest's carbon dioxide absorption by scattering sunlight, which helps plants with photosynthesis. This shows that aerosols significantly alter the Amazon's microclimate and its crucial role in the global carbon and water cycles.
