What Are Sources Of The Greenhouse Gas Methane?
Sometimes it is hotly debated whether global warming is really a human-made problem. For instance, one of the worst climage-change gases is methane (CH4). It is 23 times more potent (in terms of promoting global warming) than carbon dioxide. Some of it is produced from natural sources (not man-made). Estimates of where methane is coming from are, unfortunately, far from certain.
