Quote of the day

People say we're running out of energy. That's only true if we stick with these old 19th century technologies. We are awash in energy from sunlight.

Smell of forest pine can limit climate change

RATE THIS! +42

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. These particles form clouds that block sunlight as well as reflecting rays back into space.
 
They can be formed in a number of ways, including volcanic activity and by humans, through the burning of coal and oil. According to the Intergovernmental Panel on Climate Change (IPCC), they "continue to contribute the largest uncertainty to estimates and interpretations of the Earth's changing energy budget."
 
One of the most significant but least understood sources of aerosols are the sweet-smelling vapours found in pine forests in North America, northern Europe and Russia.

It is always great to add to understanding of factors that are linked to climate change. This work on pine trees is indeed very significant for future considerations Reply

The properties of these organic vapours from trees are amazing! They stick to the smallest particles in the air and help grow them up in size to become aerosols Reply

This is all very good news. It seems that the aerosols are playing a significant role in reducing the impact of rising temperatures. It is also possible this effect is likely to strengthen in the future. Some hope for protection!

We should also note that they are saying that the new understanding is not a cure for climate change as forests will stop emitting vapours if they become too stressed from heat or lack of water. So, this will help only if other measures are applied more globally Reply
