Ozone's Role
- The ozone layer, composed of O3 molecules, absorbs most of the sun's ultraviolet (UV) radiation.
- This absorption protects life on Earth's surface by preventing DNA damage.
HCFC Phase-Out
- Samuel Case, an AC technician, noted the impact of the 2014 phase-out of HCFC R22, a refrigerant.
- This phase-out demonstrates a successful legislative response to ozone depletion.
Focus on CO2
- Prioritize reducing fossil fuel use over solely focusing on other greenhouse gases.
- While methane reduction is important, carbon dioxide from fossil fuels remains the primary driver of climate change.
