Expert Answer
- Our earth absorbs a part of the incoming solar radiation and rest is radiated back to the atmosphere.
- Gases like carbon dioxide, methane, CFCs are called green house gases as they trap this heat energy and cause rise in atmospheric temperature.
- By adding more carbon dioxide to the atmosphere, people are supercharging the natural greenhouse effect, causing global temperature to rise resulting in global warming.
- In this way carbon dioxide is harmful for our environment.
