Carbon dioxide, one of the main greenhouse gases, makes up approximately 0.03% of Earth’s atmosphere and 95% of Mars’ atmosphere. However, scientists have not observed any significant greenhouse effect on Mars.
What accounts for this observed difference related to the greenhouse effect on Earth and Mars?
Responses
The oceans of Mars are able to absorb the carbon dioxide so that it does not cause a greenhouse effect.

The greenhouse effect is human-made, and because there is no life on Mars, there is no greenhouse effect.

The atmosphere of Mars is much thinner than Earth’s and so does not trap outgoing heat.

The greenhouse effect is primarily an Earth phenomenon and not one on other planets.
