GLOBAL WARMING -- Everywhere is warming twice as fast as everywhere else!!!!!!

An excellent example of a closed system.

Quite right. ANY thermodynamic system is defined by the boundaries that are chosen. Any energy from outside that system or any energy sink outside that system is simply not considered.
Lefty is trying to compare two different systems as if they were the same system, and define the system as if it had no boundary.

Even the entire known Universe is a closed system.

According to the 2nd law of thermodynamics: e(t+1) >= e(t) where 'e' is entropy, and 't' is time. In other words, entropy can never decrease in any given system. It MUST increase or stay the same.
Lefty just likes to troll, making random statements and word mashing. As a side effect, he is trying to argue that entropy can decrease in a given system.

Entropy itself is somewhat misunderstood by most. It does NOT mean the randomness of the system. It only means the available energy that can do work (by dissipation).

Both internal and external combustion engines are called 'heat engines' for a reason. Every single one has a 'hot' section and a 'cold' section. It is thermal energy flowing from 'hot' to 'cold' that allows the engine to run.
That 'cold' section is often just the outside medium (atmosphere, water, whatever). That flow is 'heat'. Energy always dissipates until it is uniform across the system.

At that time, there is no more heat. Heat within that system is zero.

IMO he doesn’t understand the difference between a closed system and an isolated system and he thinks we’re saying the earth is an isolated system which of course would be wrong. Either that or he’s so fucking thick he doesn’t have the learning ability of a monkey.
Probably both.

A closed system is 'isolated' by definition. In other words, NO energy source or sink that is outside that given system is simply not considered.

For example:
If you consider the system to be a refrigerator and your home, unplugging the refrigerator (removing the effect of a power plant outside your home), that refrigerator will no longer remain cold. It will reach the temperature of the room, and no insulation that is built into the cabinet will change that. The entropy in that system is increasing. Thermal energy is dissipating from the room into the refrigerator (heating the interior of the refrigerator) until they are equal, and heat reaches zero.

Now let's consider this under a different system, this time including the power plant.

That power plant must burn fuel to generate the power necessary to run your refrigerator. The entropy in that system is still increasing. If that power plant burns all of it's fuel, it shuts down since it's boiler grows cold. That means no power for the refrigerator again, and the room will heat the refrigerator until it's interior is equal to the room temperature. Again, heat occurs until full dissipation, and heat stop (it becomes zero).

Taking the Earth itself as a system, the Church of Global Warming is claiming that a magick Holy Gas is somehow capable of increasing the temperature of the Earth by itself, effectively creating energy out of nothing. This is in direct violation of the 1st law of thermodynamics. IBDaMann has labelled this stage of their argument as 2a.

Taking the Sun-Earth-space as a system, the Church of Global Warming is claiming that a magick Holy Gas is somehow capable of allowing heat to flow only one way, and is actually attempting to justify heating the surface using a colder gas. This is a reduction of entropy, and is in direct violation of the 2nd law of thermodynamics. Heat never flows from a dissipated state to a concentration of energy. It is not possible to heat a warmer object with a colder one. IBDaMann has labelled this stage of their argument as 2b.

The Church of Global Warming also makes the claim that one substance converts thermal energy to light, but not another. This is in direct violation of the Stefan-Boltzmann law, which has no term for frequency (all frequencies are considered) or type of substance (all substances convert thermal energy to light in exactly the same way, regardless of the substance).

I have even seen the Church of Global Warming try to claim the Stefan-Boltzmann law only applies to perfect black bodies (the perfect black body is merely a reference point in this law, and is an ideal. There are no perfect black bodies). Another error they often make is to try to claim the Stefan-Boltzmann law calculates temperature (it doesn't). IBDaMann has labelled this stage of their argument as 2c.

Round and round it goes, pivoting from argument to argument. These are the three 'sermons' preached by the Church of Global Warming. It really is just these, repeating over and over.

Oh I understand the difference. You are being strict when it comes to matter. Life can not sustain without Sun.
