What are greenhouse gases?

Greenhouse gases are defined as gases that trap heat in the atmosphere and contribute to global warming. This phenomenon occurs because these gases allow sunlight to enter the atmosphere but prevent some of the heat that the Earth radiates back toward space from escaping. The primary greenhouse gases in our atmosphere include carbon dioxide, methane, nitrous oxide, and water vapor.

These gases play a crucial role in maintaining the Earth's temperature, but an excess of greenhouse gases due to human activities—such as the burning of fossil fuels and deforestation—has led to an enhanced greenhouse effect, resulting in climate change and global warming. Understanding the role of greenhouse gases is vital for addressing environmental issues related to climate change.
