Pine Forest Vapor Particles Can Limit Climate Change 124
Solo-Malee writes "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 vapors turn into aerosols above boreal forests. These particles promote cooling by reflecting sunlight back into space and helping clouds to form."

Actually, it's not aerosols that were bad for the ozone layer but rather the chlorofluorocarbons used as a propellant to aerosolize the contents most spray cans up until the late 1970s. The most well known of these was freon, created by DuPont.

FTFY.
Seriously, what about the polar vortex don't you understand? Although the eastern USA had historic lows last month, the global average temperature was the hottest January on record.
If you really want to understand how the science works (which I doubt), watch Peter Hadfield's excellent series of YouTube videos. [youtube.com] He cuts through the hype on both sides of the debate. This should be required viewing for policy makers and "armchair experts" alike.
It's also fairly entertaining.

An aerosol is "a colloid of fine solid particles or liquid droplets, in air or another gas" [wikipedia.org]. The particular aeorsol (CFCs) referred to by parent is explained by a sibling post, so no need to repeat here. Point is, that an aerosol can be almost anything gaseous or that can be made fine enough to behave sort of "gas like", including dust, VOCs, smoke, etc. That's how the term is used in TFA: terpenes -- not CFCs -- are the substances "dissolved" in air.
