Researchers in Finland have observed a plant-induced cooling effect in the atmosphere, which strengthens as temperatures increase. Their results could provide important guidance for climate models that include the influence of aerosols in the atmosphere. Organic aerosols are tiny particles that include dust, ash, and pollen.
