How does destruction of the ozone layer cause global warming

The destruction of the ozone layer and global warming are two separate but related phenomena. Ozone depletion is caused by the release of chemicals containing chlorine and bromine, such as chlorofluorocarbons (CFCs), which break down the ozone molecules in the atmosphere.

The destruction of the ozone layer leads to more ultraviolet radiation from the sun penetrating the Earth's atmosphere. This causes the Earth's surface to warm up, leading to global warming. The increase in ultraviolet radiation also affects the growth of plants and phytoplankton, which are important for absorbing carbon dioxide from the atmosphere through photosynthesis.

In addition to this, the release of CFCs and other ozone-depleting chemicals also contribute to the greenhouse effect, which traps heat in the Earth's atmosphere and leads to further warming. So, although the destruction of the ozone layer may not directly cause global warming, it is a contributing factor to the overall process.
