A study shows that through aerosol formation and growth, the forests are capable of mitigating climate change and have a regional effect on the climate of an entire continent at the most. Prior research has shown that boreal forests release gaseous compounds that form aerosol particles. Mixing upwards from the surface, these aerosol particles have the ability to influence the properties of clouds (e.g., increasing their reflectivity), potentially impacting the entire climate system by cooling the climate.
