True or False: Ozone depletion contributes to global warming.

1. True

2. False

3. Depends on the area

4. Not enough data

The correct answer is: True

The statement that ozone depletion contributes to global warming is true. Ozone depletion primarily occurs in the stratosphere, where ozone (O3) molecules help to filter out harmful ultraviolet (UV) radiation from the sun. While the stratospheric ozone layer is crucial for protecting living organisms, its depletion leads to increased levels of UV radiation reaching the Earth's surface, which can cause various environmental problems including harm to ecosystems and human health. Additionally, the relationship between ozone depletion and global warming is also linked to the greenhouse gases that are often associated with substances that contribute to ozone layer destruction, such as chlorofluorocarbons (CFCs). When these gases accumulate in the atmosphere, they not only contribute to ozone layer damage but also function as potent greenhouse gases. This means they trap heat in the atmosphere, thereby contributing to global warming. In summary, the depletion of the ozone layer has indirect effects on climate change through the mechanisms described, solidifying the position that ozone depletion does indeed contribute to global warming.
