When a car is parked directly under the sun with its windows completely heatedopenedclosed, the internal temperature of the car quickly rises. This is because of the greenhouseglobal warmingcarbon dioxide effect.

The short-wavelength infrared radiation from the sun passes through the car's windows and heats the interior. Long-wavelength heat radiations are emitted by changedheatedcooled interior sections and upholstery of the car. These long-wavelength heat radiations will not be able to travel through the car's glass windows. As a result, heat is trapped within the vehicle, raising the interior volumepressuretemperature.
