ENTRY DESCRIPTION

No Longer can the Runaway Greenhouse Effect of Venus’ CO2 atmosphere be argued as Global Warming. New atmospheric models show water vapor released by high flying jetliners’ fuel, above weather systems where H2O doesn’t precipitate, causes Global Warming.

Venus has always been touted as the planet with the runaway greenhouse effect. With new atmospheric models we now know that this is not true (see Fig. 1). Most of the sun’s energy does not make it to the surface so the surface should be cool. Also the poles are almost as hot as the equator (See Fig.2). This means that the surface of Venus is geothermally heated. Venus is radiating more heat into space then it receives. We need to relook at the existing data to determine that Venus is indeed radiating more heat than it receives from the sun. We will have to give up the argument that earth could undergo a runaway greenhouse effect just like Venus. This same model also predicts that it is not the CO2 produced close to the earth’s surface that is warming the earth but rather the CO2 and Water Vapor that is released by high flying airliners that is causing global warming. CO2 produced close to the earth’s surface is quickly reabsorbed by the ocean and plants. Every greenhouse operator using CO2 enrichment knows this, but Water Vapor (Mol Wt. 18) is lighter than air (Mol Wt. 29) and when it is released high in our atmosphere, above the weather systems, it just keeps rising and is never precipitated out (See Fig. 4). Water Vapor is a strong heat absorber (See Fig. 3), also the CO2 (Mol Wt. 44) released by jet fuel high in the atmosphere, although heaver than air, takes many years to sink back down to the oceans and plants to be reabsorbed. These facts are most important to changing our greenhouse gas emitting policies. The fix may be as easy as developing a jet fuel that also emits precipitating Nuclei.
