NASA | Widely Used Coolants Contribute to Ozone Depletion

Hydrofluorocarbons (HFCS), initially considered safe for the ozone layer, are now found to contribute to ozone depletion and global warming. Originally created to replace chlorofluorocarbons, HFCS lack chlorine atoms but still impact the ozone layer by trapping heat and accelerating chemical reactions. NASA's study shows HFCS could reduce global ozone levels by 0.035% by 2050, a significant increase from previous estimates. Additionally, HFCS are potent greenhouse gases, potentially contributing up to 20% of the warming effect of carbon dioxide by 2050. Understanding these impacts is crucial for future climate and environmental research.
