Absorption and emission are processes involving energy, not a perfect mirror reflecting every ray. Some infrared radiation escapes directly and some is emitted by the atmosphere. When incoming and outgoing energy differ, the climate system gains or loses energy. A later balance can occur at a different temperature.

Infrared radiation
Electromagnetic radiation emitted strongly by Earth’s warm surface and atmosphere.
Emission
A process that sends out radiation.

Original radiation-path schematic; the interaction setting is not a CO₂-to-temperature forecast.
What to look for
- Distinguish sunlight from outgoing infrared.
- Follow both upward and downward emission.
- Look for paths that still reach space.
Explain what you noticed
In a separate energy diagram, some infrared rays escape while others are absorbed and re-emitted. Is that compatible with a greenhouse effect?
Keep this idea: Greenhouse gases absorb and emit infrared radiation, slowing heat loss until the energy balance adjusts.
