Natural gas (mostly methane) is an even more potent greenhouse gas when it escapes into the atmosphere prior to being burned. Since the industrial age began circa 1750–1850 with growing wood and coal use, the atmospheric concentration of carbon dioxide and methane have increased about 50% and 150%, respectively, above their relatively stable ...
