Timeless home truths about carbon dioxide


CO2 Absorption Spectrum

There is no Valid Mechanism for CO2 Creating Global Warming

Proof: Laboratory measurements show that carbon dioxide absorbs to extinction at its main peak in 10 meters under atmospheric conditions.* This means there is no radiation left at those frequencies after 10 meters. If then humans double their 3% input of CO2 into the atmosphere, the distance of absorption reduces to 9.7m.
A reduction in distance is not an increase in temperature.
Convectional currents stir the heat around removing any relevance for distance.
Scientists who promote the global warming hype try to work around this fact by claiming something different happens higher in the atmosphere, which they claim
involves unsaturation. The difference due to height is that the absorption peaks get
smaller and sharper, so they separate from each other. Near the earth's surface, the absorption peaks for water vapor partially overlap the absorption peaks for CO2.
Supposedly, in some obfuscated way, separating the peaks creates global warming. There is no real logic to that claim. It is nothing but an attempt to salvage global warming propaganda through obfuscation of complexities.
What it means is that climatologists admit there is no mechanism at lower levels of the atmosphere, and their rationalization for higher up is phony.
It's important to realize that radiation from the sun does not greatly heat the atmosphere, because the sun must give off high frequency radiation in the area of visible light, which goes through the atmosphere. Something as hot as the sun cannot give off low frequency radiation, called infrared. This means that the sun's radiation heats the surface of the earth, and then the heat moves from the earth's surface into the atmosphere through conduction, convection, evaporation and infrared radiation. The infrared radiation can be absorbed by so-called greenhouse gasses.

The Absorption Peaks

Carbon dioxide absorbs infrared radiation (IR) in three narrow bands of frequencies, which are 2.7, 4.3 and 15 micrometers (µM). This means that most of the heat producing radiation escapes it. About 8% of the available black body radiation is picked up by these "fingerprint" frequencies of CO2.
