Why is global warming often referred to as the greenhouse effect?

Global warming is often called the greenhouse effect because it is caused by the trapping of heat in Earth’s atmosphere, similar to how a greenhouse traps heat inside.

Explanation of the Greenhouse Effect:

1. The sun’s rays enter the Earth’s atmosphere and warm the surface.

2. The Earth’s surface emits heat in the form of infrared radiation.

3. Greenhouse gases such as CO₂, CH₄, and N₂O trap some of this heat, preventing it from escaping back into space.

4. This trapped heat keeps the Earth warm, but excessive greenhouse gases are causing an unnatural rise in temperature, leading to global warming.
