The major cause of the greenhouse effect is carbon dioxide in the atmosphere. While other gases and particles, including soot, can contribute to atmospheric warming and air pollution, carbon dioxide (CO2) is the primary greenhouse gas responsible for trapping heat in the Earth's atmosphere and is a significant driver of climate change.
