In 2016 atmospheric scientist Professor Murry Salby delivered a lecture at University College London.  The purpose of his lecture was to provide proof of why atmospheric carbon is not a pollutant and why humans cannot regulate it.

The effect of fossil fuel on CO2 emissions is minute, Prof. Salby said.  “The fossil fuel perturbation is too small to even be detectable … [It] is presently not detectable.  It will not be detectable, ever.”

Science has been taken over by “government bureaucracy under the aegis of the UN.”  Its objective, he said in 2016, “has become an exercise in social engineering to predict and control the undetectable.”

Who is Murry Salby?

Murry Salby was critical of anthropogenic global warming. His last position in academia was as a professor at Macquarie University, Sydney, Australia. 

According to Wikipedia, in 2013 the university dismissed Prof. Salby on grounds of refusal to teach and misuse of university resources.  DeSmog highlighted on Prof. Salby’s profile page that “between 1988 and 2013, Salby committed financial and other offences that led to his departures from faculty positions at two major universities.” 

Regarding Macquarie University it appears DeSmog used an in-house report that could not have been accessed without requesting it under the Freedom of Information Act (“FoI”). “DeSmog vaguely suggest there ‘must have been an FoI’, but there are no links to support that. In the end, a confidential, low standard, internal document with legalistic sounding words, may have been ‘leaked’ to those in search of a character attack,” Jo Nova noted.

Prof. Salby’s dismissal from Macquarie University followed a series of unfulfilled commitments by the university, deliberate attempts by the university to sabotage and silence him and a misconduct hearing held by the university while Prof. Salby was in France. As Jo Nova noted at the time: “Is his research is so dangerous to the cash cow that is ‘global warming’ that it had to be stopped at any cost?” 

Prof. Salby died in 2022.

Despite the persecution he suffered for going against the climate change narrative, Prof. Salby did not stop speaking out about what he knew to be the truth, as demonstrated by the lecture he gave at University College London in 2016.

During this lecture, Prof. Salby demonstrated why carbon dioxide is not a pollutant as climate change catastrophists claim

Carbon Dioxide is Not a Pollutant

Almost all of the carbon in the atmosphere is in the form of carbon dioxide, Prof. Salby explained.  Carbon dioxide cannot be a pollutant, he said, because the combustion of hydrocarbons is a form of oxidation. 

Combustion is a type of oxidation reaction because it involves the addition of oxygen to a substance, resulting in the loss of electrons and an increase in oxidation state. In combustion, the fuel reacts with oxygen to produce heat, light and oxidised products, such as carbon dioxide and water.

The plumes of “smoke” you see coming out of towers that are used as the poster child for “climate change” is water vapor, not CO2, Prof. Salby said.

It is also water vapour that you see coming out of car exhausts on a cold morning. And the same process of oxidation powers the human body.  In this process, CO2 cannot be produced without simultaneously producing water vapour. CO2 and water are the products of perfect combustion.

Methane, for example, is a simple fuel.  In the combustion of methane, for every molecule of CO2 produced, two molecules of water vapour are produced.

Appalachian coal is an example of a more complex fuel.  In its combustion, for every three CO2 molecules produced, two molecules of water vapour are produced.

“In regard to climate, whether the ratio of water vapor to CO2 is two to one or two to three really doesn’t matter,” Prof. Salby said.  He explained why it doesn’t matter using the opacity of infrared radiation.
