Carbon Monoxide rapidly changes over into Carbon Dioxide in the free atmosphere. Carbon Dioxide is heavier than Oxygen, Nitrogen, Helium, Hydrogen, and it sinks to the surface of the Earth. At the surface of the Earth CO2 is absorbed by plants, shrubs, and trees which emit Oxygen in return.
Travel by Jet Aircraft has increased ten fold in the last ten years. Jet planes emit millions and millions of cubic feet of CO2 and CO as they make cross country and transcontinental flights. When they emit the gas, they do so at very high altitudes which are unreachable by plants, shrubs, and trees.
The gases must first cool down and then settle to the surface of the Earth for that cleansing action to take place. Who is concerned about Jet Aircraft causing Global Warming? It seems like the only concern is automobiles, buses and trucks. If Global Warming is a killer like they say why arn't we seeing massive evergreen shrub and evergreen tree planting activities by the US Government???
