Greenhouse gases such as carbon dioxide, methane and water vapour naturally trap a portion of the infrared heat radiated from the earth's surface, keeping the average global surface temperature around a life-friendly 15C. If this natural greenhouse effect were absent entirely, that trapped heat would escape freely into space, and calculations suggest earth's average surface temperature would fall to roughly -18C -- cold enough to freeze the oceans and make most of the planet uninhabitable for the vast majority of present-day life forms, which require liquid water and a much narrower temperature range. It is important to distinguish this natural, life-sustaining greenhouse effect from the current environmental problem, which is the human-caused …
