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 in the stratosphere filters out ultraviolet radiation from the sun that is harmful to life on earth.
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 inhaled.
The ozone layer in the stratosphere is earth’s sunscreen and protects living things from too much ultraviolet radiation.
