The Climate Narrative is Collapsing

overwhelming scientific consensus

1. Miasma Theory
For centuries, doctors and scholars believed diseases such as cholera, plague and typhoid were spread by “bad air” arising from foul-smelling places.

The idea seemed reasonable. Areas with poor sanitation often smelled unpleasant, and those same places tended to suffer higher rates of disease. At the time, nobody knew that bacteria and viruses existed, so the connection between foul smells and illness appeared obvious.

The theory began to unravel in the nineteenth century. John Snow’s investigation of the 1854 cholera outbreak in London linked the disease to contaminated water rather than bad air. Later, the work of Louis Pasteur, Robert Koch, and others established germ theory, demonstrating that microorganisms were responsible for many diseases.

Takeaway: Observations can point in the right direction while still leading to the wrong explanation.

2. Geocentrism
For much of recorded history, the accepted view was that the Earth occupied the centre of the universe and that the Sun, planets and stars revolved around it.

This wasn’t an unreasonable conclusion. Looking up at the sky, everything appears to move around a stationary Earth. The Ptolemaic system could also predict planetary motion with a fair degree of accuracy, which gave it credibility.

The model eventually gave way to heliocentrism. Copernicus proposed that the Earth orbited the Sun, Galileo’s observations provided supporting evidence, and Kepler’s laws of planetary motion explained how the planets moved. Newton later provided the physical explanation through his theory of gravity.

Takeaway: What appears self-evident is not always correct.

3. Phlogiston Theory
Before modern chemistry emerged, many scientists believed combustible materials contained a substance known as “phlogiston”, which was released when something burned.

The theory seemed to explain both combustion and rusting, and for a time it was widely accepted as the best available explanation.

Its downfall came through careful measurement. Antoine Lavoisier demonstrated that combustion involved materials combining with oxygen rather than releasing an invisible substance. In some cases, materials actually gained weight when burned, directly contradicting what phlogiston theory predicted.

Takeaway: Better evidence often overturns ideas that once seemed perfectly logical.

4. The Luminiferous Ether
In the nineteenth century, physicists generally believed that light travelled through a mysterious medium known as the ether.

The reasoning was straightforward. Every known wave, whether sound or water waves, required a medium through which to travel. It therefore seemed natural to assume light required one as well.
The problem was that nobody could find it. The famous Michelson-Morley experiment failed to detect any evidence of the ether’s existence. Einstein’s theory of special relativity later showed that light did not require a medium at all.

Takeaway: Even well-reasoned assumptions can collapse when confronted with experimental evidence.

5. Fixed Continents
Before the development of plate tectonics, most geologists believed that continents and ocean basins were essentially permanent features that did not move.

When Alfred Wegener proposed continental drift in the early twentieth century, many scientists dismissed the idea because he could not explain how entire continents could shift across the Earth’s surface.

Over time, evidence accumulated. The discovery of mid-ocean ridges, seafloor spreading, and the movement of tectonic plates eventually transformed geology. What had earlier seemed implausible became the foundation of modern Earth science.

Takeaway: A theory can be broadly correct even if the mechanism behind it has not yet been discovered.
