Chemistry Expert: Carbon Dioxide Can’t Cause Global Warming

[Humans are Free]: Scarcely a day goes by without us being warned of coastal inundation by rising seas due to global warming.

Why on earth do we attribute any heating of the oceans to carbon dioxide, when there is a far more obvious culprit, and when such a straightforward examination of the thermodynamics render it impossible.

Carbon dioxide, we are told, traps heat that has been irradiated by the oceans, and this warms the oceans and melts the polar ice caps. While this seems a plausible proposition at first glance, when one actually examines it closely a major flaw emerges.

In a nutshell, water takes a lot of energy to heat up, and air doesn’t contain much. In fact, on a volume/volume basis, the ratio of heat capacities is about 3300 to 1. This means that to heat 1 litre of water by 1˚C it would take 3300 litres of air that was 2˚C hotter, or 1 litre of air that was about 3300˚C hotter!

This shouldn’t surprise anyone. If you ran a cold bath and then tried to heat it by putting a dozen heaters in the room, does anyone believe that the water would ever get hot?

The problem gets even stickier when you consider the size of the ocean. Basically, there is too much water and not enough air.

The ocean contains a colossal 1,500,000,000,000,000,000,000 litres of water! To heat it, even by a small amount, takes a staggering amount of energy. To heat it by a mere 1˚C, for example, an astonishing 6,000,000,000,000,000,000,000,000 joules of energy are required.

Let’s put this amount of energy in perspective. If we all turned off all our appliances and went and lived in caves, and then devoted every coal, nuclear, gas, hydro, wind and solar power plant to just heating the ocean, it would take a breathtaking 32,000 years to heat the ocean by just this 1˚C!

In short, our influence on our climate, even if we really tried, is miniscule!

So it makes sense to ask the question – if the ocean were to be heated by ‘greenhouse warming’ of the atmosphere, how hot would the air have to get? If the entire ocean is heated by 1˚C, how much would the air have to be heated by to contain enough heat to do the job?

Well, unfortunately for every ton of water there is only a kilogram of air. Taking into account the relative heat capacities and absolute masses, we arrive at the astonishing figure of 4,000˚C.

That is, if we wanted to heat the entire ocean by 1˚C, and wanted to do it by heating the air above it, we’d have to heat the air to about 4,000˚C hotter than the water.

And another problem is that air sits on top of water – how would hot air heat deep into the ocean? Even if the surface warmed, the warm water would just sit on top of the cold water....<<<Read The Full Article Here>>>...
