Earth-sized egg

Classical Mechanics Level 1

The Earth is protected by a layer of atmosphere that can absorb heat from the Earth. Does this keep the Earth warmer, cooler, or at the same temperature as it would be without the atmosphere?

Details

For simplicity, we assume that the atmosphere is transparent to radiation from the Sun. It can only absorb infrared radiation from the Earth, which is created when radiation from the Sun hits the Earth.
