Description: 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: esrl.noaa.gov/csl/assessments/ozone/2018/downloads/twentyquestions/Q8.pdf And to learn why the Antarctic is most susceptible to ozone damage, check out the following: esrl.noaa.gov/csl/assessments/ozone/2018/downloads/twentyquestions/Q9.pdf You might also like: UNTOLD | Challenger: The Real Story of an Avoidable Disaster youtube.com/watch?v=uI174WMnWl4 UNTOLD | The Terrifying (but Awesome) Science Behind Red Tides youtube.com/watch?v=R7t7qrH_dsc UNTOLD | The Invisible Tsunami That Killed 1,500 People in One Night youtube.com/watch?v=rNKDx3kR3tk UNTOLD | The Great MOLASSES Flood of 1919 youtube.com/watch?v=iMPGm3OSvMg Credits: Executive Producers: George Zaidan Hilary Hudson Producer/Editor: Darren Weaver Writer/Host: Alex Dainis, PhD Assistant Editor: Brett Kuxhausen Animator: Shea Lord Fact Checker: Bob Hunt Archive Producer: Annalea Embree Coordinating Producer: Samantha Jones, PhD Scientific Consultants: Michelle Boucher, PhD James Elkins, PhD Andrew Jordan, PhD Stephen Montzka, PhD Brianne Raccor, PhD Sources: docs.google.com/document/d/1Gkvr9l3z38R-vJ6DHVniQsasfqGO0ZaQed-8hwvoYho/edit?usp=sharing Produced by the American Chemical Society.
