|The so-called 'Greenhouse Effect' is caused primarily by:||c) aerosol sprays|
No, this is incorrect.
Aerosol sprays are not related in any way to the ‘greenhouse effect’. They were mistakenly linked to ozone destruction in the upper atmosphere as Chlorofluorocarbons (CFCs) were incorrectly implicated in ozone depletion. In reality, variations in ultraviolet radiation that creates upper atmosphere ozone were responsible for changes in ozone levels. New research shows the UN made significant errors in chloride chemistry in this issue.
