The smell of forest pine can limit climate change

Friday 2 May 2014

The fresh scent of pine trees has a significant impact on climate change. New research suggests a strong link between the powerful smell of pine trees and climate change. Scientists say they've found a mechanism by which these scented vapours turn into aerosols above boreal forests. These particles promote cooling by reflecting sunlight back into space and helping clouds to form.

The research, published in the journal Nature, fills in a major gap in our understanding, researchers say. One of the biggest holes in scientific knowledge about climate change relates to the scale of the impact of atmospheric aerosols on temperatures.
