The Greenhouse Effect – It’s Simple Physics – NOT: One of the disturbing characteristics of many politicians, “experts” on climate science, and even established scientific organizations is to talk about the greenhouse effect as simple physics. It is not. It is a complex process that has been ongoing for billions of years with varying concentrations of atmospheric gases, that have changed significantly. Human emissions of carbon dioxide are not changing the atmosphere to something that has not existed before. One cannot be certain, but the early atmosphere may have been mostly of carbon dioxide, along with smaller amounts of methane, ammonia, nitrogen and water vapor. Today, “dry” atmosphere (from which all water has been removed) is about 78% nitrogen, 21% oxygen, 1% argon and 0.4% carbon dioxide. (Due to rounding, numbers may not equal 100%.)
Of course, dry air only exists in a laboratory, and any calculations based on dry air must be verified by observations. Unfortunately, such necessary observations are ignored by the UN Intergovernmental Panel on Climate Change (IPCC) and its followers such as the US Global Change Research Program (USGCRP). Instead, these organizations add an assumed influence of the importance of water vapor, not one based on observations.
