What kind of gas increases the temperature in the atmosphere?

Greenhouse gases, such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), contribute to the warming of the atmosphere. These gases trap heat from the Earth's surface, preventing it from escaping into space, a phenomenon known as the greenhouse effect. As their concentrations increase due to human activities like burning fossil fuels and deforestation, they lead to rising global temperatures and climate change.
