Turn About Is Fair Play!

Since some Global Warming Proponents felt the need to post on the I don't believe in global warming group, I felt it was okay to come over here and see if anyone here who can adequately explain this little quandary. If Global Warming is Man-made, why has the temperature on all the other planets and moons in our Solar System also increased?

If you can explain to me how man, driving his SUVs, and carbon emissions has managed to pull that off, I'll agree with your premise, but i no one can, it's time to admit, it's called Climate Change and it has varied for the last few Billion years and man's insignificant contribution has nothing what so ever to do with it.

It is true that all the planets have gotten warmer in the last 630 million years. The explanation is that the solar constant has increased by about 6 per cent in that time, according to what astronomers call the "main star sequence", of which the Sun is a part. Due to what is called the Stefan-Boltzmann equation, temperature rises according to the fourth root of solar radiation received, if the other factors albedo and atmospheric composition remain essentially the same. A 6 per cent increase of the solar constant thus leads to a roughly 1 1/2 per cent increase in temperature on the Kelvin scale.

On Earth, due to the increased evaporation of water vapour into the atmosphere with the increased heat, Earth tries hard on a geological time scale with the 6 per cent higher solar constant to keep a modern ratio of at least 11.2 to 1 of water vapour to CO2. An increase in CO2 leads to an increase in water vapour on a very short geological time scale, noticeable within human life span. Over most of Earth, with the notable exception of the still glaciated polar regions, water vapour is the chief greenhouse gas. In Earth's atmosphere, as the water vapour content plays catch-up with the rapidly rising CO2 level, Earth's greenhouse effect will increase from the increased water vapour, explaining the record Greenland and Arctic ice melts that will occur between now (2013.06.02) and the end of the decade (technically 2020.12.31).
