Growing up in the 1980s, I can still remember being taught in school about the dangers of global warming and the hole in the ozone layer. The narrative was that chlorofluorocarbons (CFCs), widely used in refrigeration, air conditioning, foam insulation, solvents, and aerosol propellants, were depleting the ozone layer, and that this depletion might be irreversible. We were told it would be unsafe to go outside without being covered up, even in the summer, if this came to pass. People were shamed into believing their modern lifestyles were killing the ozone layer.
