Ozone Layer Depletion and Global Warming
- Ozone layer depletion and global warming are two separate environmental issues, but they are connected in a complex way
- The ozone layer absorbs UV-B radiation, which heats the stratosphere, causing it to cool the troposphere
- When the ozone layer is depleted, more UV-B radiation reaches the troposphere, leading to increased temperatures
- The increased temperatures in the troposphere accelerate the trapping of greenhouse gases, contributing to global warming
- Ozone-depleting substances, such as chlorofluorocarbons (CFCs), are also potent greenhouse gases, exacerbating global warming
- The Montreal Protocol, which controls the production and consumption of ozone-depleting substances, has helped to reduce the amount of these gases in the atmosphere, slowing global warming
