ABSTRACT

A greenhouse gas is a gas that absorbs and emits infrared radiation.

The primary greenhouse gases in the atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Atmospheric carbon dioxide (CO₂) is a nontoxic, colorless, odorless gas.

Water vapor accounts for by far the largest greenhouse effect (90–85%) because water vapor emits and absorbs infrared radiation at many more wavelengths than any of the other greenhouse gases, and there is much more water vapor in the atmosphere than any of the other greenhouse gases. CO₂ makes up only a tiny portion of the atmosphere (0.040%) and constitutes only 3.6% of the greenhouse effect. The atmospheric content of CO₂ has increased only 0.008% since emissions began to soar after 1945. Such a tiny increment of increase in CO₂ cannot cause the 10°F increase in temperature predicted by CO₂ advocates.

Computer climate modelers build into their models a high water vapor component, which they claim is due to increased atmospheric water vapor caused by very small warming from CO₂, and since water vapor makes up 90–95% of the greenhouse effect, they claim the result will be warming.

The problem is that atmospheric water vapor has actually declined since 1948, not increased as demanded by climate models. If CO₂ causes global warming, then CO₂ should always precede warming when the Earth’s climate warms up after an ice age. However, in all cases, CO₂ lags warming by ∼800 years. Shorter time spans show the same thing–warming always precedes an increase in CO₂ and therefore it cannot be the cause of the warming.
