noticeable example of the greenhouse effect these days is the heating inside
our cars in the sun. Short wavelength visible radiation passes through the
glass and heats interior surfaces.
These warm the air inside the car and the glass traps the heat inside.
early expert on heat science postulated that gases in the atmosphere could
trap heat in a similar way. Energy from the sun mostly passes through the
atmospheric blanket to warm the surface. The warmed surface re radiates
energy out toward space at longer wavelengths. The atmosphere captures some
of that energy and is warmed.
confirmed this with experiments and demonstrated that water vapor is the most
important greenhouse gas. It and other "natural" greenhouse gases
warm earth's surface atmosphere about 33 degrees C.
concerns that burning coal could add
sufficient carbon dioxide to the atmosphere to increase the greenhouse gas
effect. Callendar and Keeling confirmed rising carbon dioxide level and
established an extensive global greenhouse gas monitoring system in the mid
