How does the hole in the ozone layer affect global warming?
The hole in the ozone layer in the earth’s upper atmosphere (stratosphere) reduces the greenhouse effect because ozone is a greenhouse gas. However, ozone is needed in the stratosphere where it occurs naturally to filter out harmful ultraviolet radiation from the sun.
Ozone in the lower atmosphere (troposphere) is created by chemical reactions between pollutants and sunlight. Ozone in the troposphere is dangerous to human health because it can cause lung damage and other cardiopulmonary problems when breathed.
