Today the concentration of greenhouse gases is very high because of D) All of the above.

• Increases in the concentration of greenhouse gases such as carbon dioxide increase the average temperature of the earth's surface and cause global warming.
• Global warming is defined as the increase in temperature in the earth's atmosphere due to an increased level of carbon dioxide, CFC and other pollutants gases.
• These gases allow the light to come into the earth's atmosphere but do not allow it to go outside it and hence heating the earth's atmosphere.
