Carbon dioxide (CO2) is the gas that contributes most to global warming. It is a greenhouse gas that traps heat in the Earth's atmosphere, leading to a rise in average global temperatures.

Ozone (O3) and carbon monoxide (CO) also contribute to climate change, but to a lesser extent than CO2 and methane.
