What happens to the temperature when the atmospheric co2 level increases in this model?
lions [1.4K]

Answer:

The temperature of the surrounding air increases when the atmospheric CO2 level increases.

Explanation:

Carbondioxide gas is also called greenhouse gas because it has the ability to absorb or trap heat energy when the solar radiation goes into the space after hitting the earth surface. If the concentration of carbondioxide gas is increased, more heat energy will be trapped and thus increase occurs in the temperature of the atmosphere which results in global warming.
