Global warming is “a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons(CFC), and other pollutants.” …show more content…
They are essential, because without them, Earth would be too cold to sustain life. However, people are adding excess greenhouse gases into the atmosphere. This means that our atmosphere traps more heat, causing the Earth to overheat. We can see the effects of greenhouse gases on Venus. The planet has a thick layer of greenhouse gases, and this is the paramount reason why its surface temperature is 462 degrees Celsius. Because of the temperature, life on Venus is impossible. Could our planet have the same fate?
Among the most common greenhouse gases, carbon dioxide is the most, making up 82 percent of all greenhouse gas emissions in the United States. Burning fossil fuels for electricity, using forms of transportation, and industrial processes all release carbon dioxide into the atmosphere. Electricity produces 38 percent of all carbon dioxide released into the air, and this is because the average person tends to have more technology-based things in their home than in the last
