More or less the point of the global warming propaganda

It is directed at ignorant people who can be easily deceived.

Once again, another common everyday device shows that the assertions made by the warmists are wrong.

Consider a diesel engine.  There is a difference in how a diesel engine works versus the gasoline engine.  A gasoline engine uses spark plugs, while the diesel engine doesn't require one.  Instead of a spark plug, a glow plug is used for cold weather starts.  Other than this, the diesel engine relies solely upon the compression of the air in order provide the heat necessary to combust the diesel fuel.  The following video explains this:





Thus, it is shown that compression of air is what determines heat in a gas in this instance.  Compression just means more air molecules in a given space.

The same is true in a global context.  There is no enclosed structure, as in an engine.  So, when the air is heated, it expands, as in the engine.  The air in the atmosphere will expand and it will cool while it expands.

Hence, there can be no heat retention.  It is only retained by heat transfer from an energy source.  Since that source is the sun, it is constant, so there's nothing that's going to increase the heat in the system unless more gas is generated.  As indicated in a prior post, this doesn't happen during combustion.

It is better to make examples like this to average people because it is easy to understand and makes it harder for the deceivers to fool the majority of people.  Let's face it, not everybody is equal.  Some folks just need to have things explained to them sufficiently, and they will get it.
