The scientific community first warned about the harmful effects of CFCs (chlorofluorocarbons) on the ozone layer in the early 1970s, but it wasn't until the mid-1980s that the political community began to respond seriously, culminating in the Montreal Protocol in 1987. This marks approximately 15 years between the initial warnings and significant political action.
