Theory on climate change

I am appalled that scientists do not take into account, in their analysis of the global warming phenomena, the effect of airliners. It is estimated that there are approximately 10,000 jets flying over the earth at any one time of the day or night. Each aircraft has two or more engines spewing out hot gases in the upper troposphere.

Heat from sources at the surface of the planet dissipates as it rises. The molecules cool generally and spread out; but putting out hot air from turbofan and turbojet engines at 10-12 km above the earth is not in keeping with natural events.

If you study the increase in global warming with the increase over the last 20 years on how aviation has grown, it is concurrent. 20,000 jet engines (most airliners have at least two engines while many military aircraft may have one) exhausting at about 1200 degrees Fahrenheit at or near the tropopause is going to affect weather and thus climate.

So what can we do about it? The answer is nothing until an alternate method of propulsion is invented which does not have a burning of a fuel. Maybe space aliens will teach us how it’s done!
