Instead, thanks to greenhouse gases, the earth's average temperature is better, 60°F. But, problems may happen when the amount of greenhouse gases increases. Since the beginning of the industrial revolution, great amounts of carbon dioxide have increased nearly 30%, methane concentrations have almost doubled, and nitrous oxide concentrations have risen about 15%. These increases have made the heat-trapping worse in the earth's atmosp ...
