The greenhouse effect is responsible for global warming. Which gases are responsible for the greenhouse effect?
The greenhouse effect is primarily caused by the accumulation of certain gases in the atmosphere that trap heat. Their relative contributions to global warming are as follows:
| \text{Gas} | \text{Contribution} |
| $CO_2$ | $50\%$ |
| $CH_4$ | $19\%$ |
| $CFCs$ | $17\%$ |
