Another way would be to convert all passenger jets to hydrogen fuel. Burning hydrogen produces only water. While water vapor is a so-called greenhouse gas, the emission of water vapor from jets is usually called a contrail, a condensation trail. It is a long threadlike cloud.

And clouds reflect sunlight, cooling the Earth.

Contrails and other cirrus clouds consist almost exclusively of ice crystals and generally exist or originate in areas of ambient temperature less than -36°C. In most formations and orientations, these ice crystals reflect light far more effectively in the infrared (terrestrial radiation) than in the visible (solar radiation) and consequently warm the earth. These clouds occur far more frequently than you might realize; thin cirrus often appears almost transparent to the human eye. Most stratus clouds by contrast cool the earth.

Well, as long as you don't post that in a public forum, no harm will come of it.

Actually, I have no objection to a warming Earth, even though my property here will end up inundated after a few thousand years.

Converting all air travel to hydrogen fuel would be a way of jump-starting the "Hydrogen Economy" and its requisite atomic energy production capacity.

Then anyone who wanted to drive a hydrogen car would just have to live near an airport.

I look at the idiocy of the "Global Warming" nonsense the way I regard my wife's requests to build a project or reconditiion a room ... "Well, okay, but I'll have to pick up a few new tools ..."
