Ping Pong Ball Global Warming Experiment

See http://CoSy.com/views/warm.htm . ( originally posted 20071002 ) 20090216 : A simple computer model of the Stefan-Boltzmann law is now at http://cosy.com/Science/TemperatureOfGrayBalls.htm showing that it is correct that isotropic shading drops out of the equation . I.e.: black and white balls will come to exactly the same temperature when radiantly heated in a vacuum . The GW alarmists claim that minute changes in the reflectivity of the planet will make major changes in its mean temperature . I found no difference between a flat black painted and a natural white ping-pong ball and at most about 2c with a "chrome" painted ball . I also got a feeling for what a small change the at most 0.8c increase in temperature this century is . It's hard to get thermometer reading to be stable within less than ~ 0.2c . I'd really like to see this experiment done "professionally" in a vacuum , ( MythBusters ? ) and I'd really like to see the equations which predict exactly how much heating or cooling different paint jobs will produce . Despite the lifestyles of millions riding on this science , I have failed to find such basic equations anywhere on the web .
