Long before there was air conditioning, there were ways to keep cool. People would design buildings with passive-cooling features such as breezeways and open porches.
Nowadays, indoor environments are sealed off from the outside. They are then artificially cooled. What makes air conditioning possible are hydrofluorocarbons (HFCs). These replaced the chlorofluorocarbons (CFCs) that were eating away at our ozone layer.
Ironically, HFCs contribute to global warming via their heat-retaining qualities. So while temporarily alleviating individual discomfort, they are contributing to societal disasters.
