"Or do you never read your spam mail???" No. "That said, in the lab facts can be established based on controlled experiments. " Yes. "Next we cannot but apply this knowledge to our observations of what seems to be same or similar effects at a larger scale. " Not sure what you are trying to say here. "Now expand this scenario to global while at the same time extending the time factor to centuries or even million of years, the uncertainty factor kind of increases, doesn't it?" Maybe. But just because there is greater uncertainty, doesn't mean it doesn't happen. An example. Look a Venus. Yes, it is closer to the Sun, but it isn't all that much closer. It has a surface temperature that is hard to explain by any other method other than a greenhouse effect. Another example are two moons of Saturn, Titan and Mimas. Mimas is a typical empty rock with only a trace of an atmosphere. It has a surface temperature of about 64 degrees Kelvin. Titan, OTOH, has a very dense atmosphere with a concentration of 1.6% methane and a surface temperature of 90 degrees K. Given that are more or less the same distance from the Sun, why is Titan so much warmer unless there is a greenhouse effect?
