Hint: Greenhouse gases absorb and emit infrared radiation in the wavelength range emitted by the Earth.

Complete answer:
The accumulation of greenhouse gases (heat-trapping gases) in the atmosphere is the primary cause of climate change. Greenhouse gases are air molecules that can trap heat in the Earth's atmosphere.
Some greenhouse gases, such as carbon dioxide ($CO_2$) and methane ($CH_4$), are naturally occurring and play a significant role in Earth's climate. The world would be much colder if they didn't exist.
Greenhouse gases aid in preventing harmful solar radiation from reaching the planet's surface. These gases act as a filter, bouncing back most of the unwanted and harmful energy into space. One of the most important greenhouse gases, ozone, absorbs the sun's harmful ultraviolet (UV) rays.
On the other hand, an excess of these gases is also harmful to the environment, because the role of greenhouse gases is to trap energy from the sun and use it to warm the earth. As a result, the more gases we produce, the warmer our world becomes, leading to global warming, which may cause problems for all forms of life.

Note:
Carbon dioxide ($0.04\%$), nitrous oxide, methane, and ozone are trace gases that make up nearly 0.1 percent of the Earth's atmosphere and have a significant greenhouse effect.
