Carbon Dioxide can’t cause Global Warming

Written by Dr Mark Imisides (Industrial Chemist)

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.

Thus, if the ocean were being heated by ‘greenhouse heating’ of the air, we would see a system with enormous thermal lag – for the ocean to be only slightly warmer, the land would have to be substantially warmer, and the air much, much warmer (to create the temperature gradient that would facilitate the transfer of heat from the air to the water).

Therefore any measurable warmth in the ocean would be accompanied by a huge and obvious anomaly in the air temperatures, and we would not have to bother looking at ocean temperatures at all.

So if the air doesn’t contain enough energy to heat the oceans or melt the ice caps, what does?

The earth is tilted on its axis, and this gives us our seasons. When the southern hemisphere is tilted towards the sun, we have more direct sunlight and more of it (longer days). When it is tilted away from the sun, we have less direct sunlight and less of it (shorter days).

The direct result of this is that in summer it is hot and in winter it is cold. In winter we run the heaters in our cars, and in summer the air conditioners. In winter the polar caps freeze over and in summer 60-70% of them melt (about ten million square kilometres). In summer the water is warmer and winter it is cooler (ask any surfer).

All of these changes are directly determined by the amount of sunlight that we get. When the clouds clear and bathe us in sunlight, we don’t take off our jumper because of ‘greenhouse heating’ of the atmosphere, but because of the direct heat caused by the sunlight on our body. The sun’s influence is direct, obvious, and instantaneous.

If the enormous influence of the sun on our climate is so obvious, then, by what act of madness do we look at a variation of a fraction of a percent in any of these variables, and not look to the sun as the cause?

Why on earth (pun intended) 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.

  1. I wonder if Rod Carr will have the courage to point this out to Cindy bin Lying and her mad eco-nutter cohort?

  2. When you think about it that is a brilliant explanation of the bullshit of warming oceans. As an analogy It takes lots of extra hot water to to re-warm just a bathtub of tepid water. Monitor how much hot water you have to add next time you stay in the bath long enough for the water to cool. Now imagine how much the Pacific, Atlantic, Indian, Southern, oceans, and all the seas together around the world take to warm.

    • That’s why in these temperate climes the best swimming is near the end of summer, not the beginning. Takes a lot to heat up this big-ass ocean around us.

      Speaking of climate rubbish, I just read that 700 Billion, yes with a capital B, has been invested in “fossil fuel” infrastructure and drilling etc by the Big players SINCE Paris 2015 was paraded as the big savior of the world. Hey teenyboppers waving placards- good news right? Keep it the ground right? Right!! These guys have more cash in their wallets than we do as an entire nation.

      • There are the “$700 Billion” reasons for this huge worldwide scam. Follow the money. Terrifying school children that the world is going to end is just a part of the scam, but hey who cares who gets hurt when the left can see how to control the $$$.

  3. That was a very good explanation and one of the best I have read on the subject.

    To me it has been obvious for years that all this ‘global warming’ and now ‘climate change’ fear is bullshit…. but what I haven’t been able to understand is why the world has literally gone mad and taken all this crap on board?

    Can anybody offer an opinion on why this is happening and who is getting what out of it?

    Serious question. Who is benefitting from destroying humanity’s hitherto wonderful progress and trying to drive us back onto the 19th century?

    • The money men Dave. If we go back to the early 1990s the US introduced a cap and trade system to remove the suplate/sulphur dioxide pollution (real pollution) from industry etc. By the time the second IPCC assessment report was written about 6-7 years later it was seen to be reasonably successful . So they introduced the idea of a cap and trade (ETS system or carbon tax) into the IPCC report almost certainly under pressure from the money guys. The rest is history as they say –how did Al Gore make his billions after retiring as a relatively poor politician ?

        • Blind hatred of the western middle classes, that’s why. Climate freaks want you and I to live no better than some jungle bunny in the 3rd world who shits in a latrine. It’s so unfair! We eat McDonald’s while these wretched souls shit in latrines!

          Right! The West is the Best! Be damn grateful if you live in it FFS.

    • Actually, now that I think about it, I reckon that all the rational explanations of why the climate change fears are false on a scientific level mean nothing when talking to the general public. It all just goes over their heads.

      If we are going to argue against these draconian and stupid policies effectively, we need to explain to people why this shit is being pushed at us on international level and who is benefiting.

      Seriously. You can talk about CO2 until the cows come home…. but so far we’re not addressing the main question. Who is benefiting from the world literally going mad?

      • It’s all a big Play dude. Very good question- who and why? All I know is it’s always been here in one form of another, and my gut instinct has always been to resist that ideology to the death if required. Many of our forebears DID that. How many of these kids screaming “Govt do something” also attend ANZAC service? To explain the deep irony would be completely lost on them, sigh.

    • The same idiots who created the USSR and Cuba. History just repeating itself. A whole bunch of little kiddies are willing to sell their souls to any “Govt that will do something.”
      These are the devils Thomas Jefferson told us would one day come. They know not what they do. Freedom or death, period!

  4. The other simple fact to bear in mind is the sun does not heat the atmosphere (think of the air temperature outside a plane next time you are up there). It is the earth and the oceans that heat the atmosphere.
    This simple fact adds to the argument presented above.

  5. Seems nature and physics are ignoring the “consensus”.

    A show of hands won’t change reality even if you really really want it to.

  6. I could never figure out how global warming could suddenly stop warming the land and start putting the heat deep in the ocean.

    This theory of “Intelligent warming” struct me as being made to order, and began to form the idea that this was a bit of a cult.
