temperature?
A) It would be less than the present.
B) It would be same as present.

Answer:
i guess A would he the right ans
Carbon dioxide is an atmospheric constituent that plays several vital roles in the environment. It is a greenhouse gas that traps infrared radiation heat in the atmosphere. It plays a crucial role in the weathering of rocks. It is the carbon source for plants. It is stored in biomass, organic matter in sediments, and in carbonate rocks like limestone. The ability of CO
2
to warm the surface of a planet through the absorption of infrared radiation is well known. What is much less appreciated, however, is just how effective of a gas it is in maintaining the greenhouse framework that helps to characterize the modern climate. MIT scientist Dr. Richard Lindzen, who suggested that such a hypothetical removal of all the CO
2
in the air would translate into a global cooling of about 2.5 degrees. So, if there was no CO
2
in the earth's atmosphere, the temperature of earth's surface would be less than the present. Thus, option B is correct.
If there was no CO
2
in the Earth's atmosphere, the temperature of Earth's surface would not be same as present or not higher than the present or it do not depends on amount of oxygen in the atmosphere.
