The picture above shows CO2 molecules and how they interact with heat coming from the Earth. What usually happens when heat (red lines) hits a CO2 molecule
(red/black particles)?
Most heat bounces off the CO2 molecules and goes to outer space
Most heat bounces off the CO2 molecules and returns to Earth
Most heat passes right through the CO2 particles and goes into outer space
Most heat passes right through the CO2 molecules but runs out of energy,
returning to Earth
