This paper describes a simple experiment to understand global warming and a physical model to explain the experimental results. The experiment apparatus is constructed two vessels. One is filled with greenhouse effect gas (HFC-134a) and the comparison vessel is filled with dry air. The upper part of vessel is maintained low temperature by ice. The surfaces of bottom of two vessels are heated by fluorescent lamps that is simulated solar. The temperature diffrence between two surfaces is about 1.3 K. A physical model is constructed to explain the experimental results. The heat balance of surface by radiation and natural convection heat transfer is considered. The experimental result agrees with the calculated one when the absorptivity of HFC-134a gas is about 0.7 〜 0.93.
