Without naturally occurring greenhouse gases, the Earth would be a much colder place, inhospitable to modern human existence. But by the same token, the additional greenhouse gases added to this store by humans is slowly increasing the average temperature of the Earth system.

Due to the quantity in which it is emitted by humans, its longevity in the atmosphere, and its effects in trapping heat, carbon dioxide is the most important of the greenhouse gases currently causing changes in the Earth’s climate……
