Question

it is converted to carbon dioxide
it is converted to solar energy
it is absorbed and heats the atmosphere
it escapes and cools the atmosphere

Answer 1

If there is an increased level of carbon dioxide in the atmosphere, the infrared radiation released by the Earth is absorbed and heats the atmosphere.

Carbon dioxide is a greenhouse gas, which means it can absorb and re-radiate infrared radiation. This process contributes to the greenhouse effect, resulting in warming of the atmosphere and influencing global temperatures.
