The hole in the ozone layer was caused by chlorofluorocarbons
the verdict
SUPPORTED
the evidence backs this
confidence 86/100
Extensive scientific research and international consensus strongly support the conclusion that chlorofluorocarbons (CFCs) were the primary driver of the hole in the ozone layer.
