The smell of pine trees helps moderate climate change
Interesting research from Australia describes how the scented vapors from pine tress (as well as emissions from volcanic activity and burning coal and oil) form aerosols that reflect sunlight back into space, thereby cooling the atmosphere.
The findings of a new research have established a very strong link between climate change and the powerful smell of pine trees. A mechanism has been discovered by scientists, which allows scented vapors to convert into aerosols above boreal forests. Aerosols are particles that cool the atmosphere by reflecting sunlight back into space and contribute to cloud buildup.
These particles are also formed by volcanic activities and through the burning of coal and oil. But, the sweet-smelling vapors found in pine forests in North America, northern Europe and Russia are the cheapest sources of aerosols.
