Whatever Happened to the Ozone Hole? A Story of A/C, Atoms, and CFCs

From Reactions.

It might feel like they’re making us cooler, but refrigerators and air conditioning are actually making our world warmer. Yes, they use a huge amount of electricity, but many older cooling methods also released tons of molecules that are still hanging around, shredding our #ozone layer. In this episode of #Untold, a new #YouTubeLearning series from ACS, PBS, and YouTube, we consider how we might keep ourselves and our food cool, without accidentally warming up our world.

The chlorine reaction we showed isn’t the only one–to learn more about bromine reactions that also destroy ozone, check out this link: https://www.esrl.noaa.gov/csl/assessments/ozone/2018/downloads/twentyquestions/Q8.pdf
