1. the greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere.The greenhouse effect occurs naturally. Lately the greenhouse effect has been magnified due to greenhouse gases emitted into the atmosphere by humans. and 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, CFCs, and other pollutants.Global warming refers to the increase in annual average temperatures across the globe. As the amount of greenhouse gases in the atmosphere increases, the planet becomes warmer and warmer on average.
2. atmospheric carbon dioxide acts as a thermostat in regulating the temperature of Earth
3. fossil fuels like coal oil and natural gasses
