If a car heats up sitting in the sun ( with windows closed ) that's a "greenhouse effect", Like a "greenhouse". But if the car started cooling when left out in the sun - with the windows up - it has NOTHING to do with a greenhouse effect..
What are the liberals saying? It doesn't make any sense. Can someone explain?
The “greenhouse effect” STRICTLY and scientifically stated (not the more recent re-interpretation by climate scientists) refers to a very clear process.
Visible light from the sun passes easily through the “transparent” to VISIBLE light and is absorbed by the materials inside the car (or the greenhouse). That energy heats the material, and the HEAT is radiated off the material. That heat is in the form of INFRARED radiation, which does NOT pass easily through the glass since glass is not transparent to those wavelengths, and is therefore trapped in the car. THIS ALONE constitutes a true “greenhouse effect”
For the energy to “escape” it must heat the glass, or otherwise be conducted to the “skin” of the car, and from there be radiated back into the atmosphere, or be released by opening the door.
