I am definitely not a Global Warming believer. However, I need help understanding why the Second Law of Thermodynamics is “proof” that this scam is a scam.

IIRC, the 2nd law involves the conservation of energy.

Energy can neither be created nor destroyed. All the energy we have comes from the Sun. CO2 can't 'create' heat, and can't be to blame for increased or decreased energy from the Sun.

Or I could be completely wrong.

Don’t have an answer....might be one in the comments.

There is some heavy conversation in the comments to the article...regarding the statement on the second law of thermodynamics.

I am only a civil engineer and I was LOUSY at Thermodynamics, so I am just going to have to guess.

I am going to guess he means that the heat being stored in the CO2 in the atmosphere can’t be higher than the heat from the solar radiation that came into the atmosphere. So in short, all of the heating the earth experiences has to be from what comes in from the sun, and not from what bounces around the planet and is trapped inside due to greenhouse gases.

I think it all comes down to:

How does a greenhouse work and does the earth’s atmosphere work the same way?

The AGW alarmists want us to believe that the earth’s atmosphere heats the earth in identical manner to a greenhouse heating a hothouse.

Two things happen in a hothouse.

First, solar radiation that enters and tries to reflect back out into the atmosphere, is re-reflected off the windows of the greenhouse and back into the hothouse.

Secondly, the enclosed hothouse prevents cooler air from entering and hotter air from leaving.

Even if the 1st thing happens in our atmosphere — even if greenhouse gases re-reflect solar radiation back toward earth causing some additional heating — there is no enclosure of the earth to prevent hot air escaping the system. Or put it another way, there is nothing to prevent hot air from rising and giving off heat into space as it rises.

So there is no proof that the Earth’s atmosphere really contains heat in the same manner that a hothouses greenhouse contains heat.

Back to the 2nd law of Thermo. Since heat can only be used once, any new heat the earth experiences has to come from some outside source, that source being the sun, or perhaps heat trapped below the crust that leaks out such as volcanoes.

But warm solar radiation that loses heat to the atmosphere, can’t bounce off clouds or get sucked up into CO2 and warm and warm and warm. It is spent. It shot it’s wad. It is done. And it does not matter how it lost it’s heat to Earth.

So since each beam of solar radiation can only transfer it’s heat to Earth one time, there can’t be any rise of heating due to the old rays that hit Earth, only from the new rays.

That’s my guess, but I’m sure we have physicists here who can explain it much better or correct me.

"The debunking of man made warming disproves the fallacy of AGW that says there exists a mechanism where carbon dioxide in the cooler upper atmosphere exerts any thermal forcing effect on the warmer surface below.

That violates the First AND Second Laws of Thermodynamics. There is no glass roof on the Earth that traps excess heat as it escapes upward and out into space. Remember, the deeper the ocean – the colder the water – and remember that heat rises – it does not fall."
