What it means to call someone a Denier

Prof. Deming echoes my sentiments, exactly.

I’m happy to be known as a “denier” because the label of “denier” says nothing about me, but everything about the person making the charge. Scientific theories are never denied or believed, they are only corroborated or falsified.

A scientific theory cannot be “denied.” Only a belief can be denied. The person who uses the word “denier” thus reveals that they hold global warming as a belief, not a scientific theory. Beliefs are the basis of revealed religion. Revelations cannot be corroborated or studied in the laboratory, so religions are based on dogmatic beliefs conservatively held. Religions tend to be closed systems of belief that reject criticism. But the sciences are open systems of knowledge that welcome criticism. I’m a scientist, and therefore I must happily confess to being a denier.

Have you ever considered how difficult it is to take the temperature of the planet Earth? What temperature will you measure? The air? The surface of the Earth absorbs more than twice as much incident heat from the Sun than the air. But if you measure the temperature of the surface, what surface are you going to measure? The solid Earth or the oceans? There is twice as much water as land on Earth. If you decide to measure water temperature, at what depth will you take the measurements? How will the time scale on which the deep ocean mixes with the shallow affect your measurements? And how, pray tell, will you determine what the average water temperature was for the South Pacific Ocean a hundred years ago? How will you combine air, land, and sea temperature measurements? Even if you use only meteorological measurements of air temperature, how will you compensate for changes in latitude, elevation, and land use?

Determining a mean planetary temperature is not straightforward, but an extremely complicated problem. Even the best data are suspect.”

The Truth About Greenhouse Gases

A dispassionate writeup, there is nothing in it I could disagree with.

The object of the Author in the following pages has been to collect the most remarkable instances of those moral epidemics which have been excited, sometimes by one cause and sometimes by another, and to show how easily the masses have been led astray, and how imitative and gregarious men are, even in their infatuations and crimes,” wrote Charles Mackay in the preface to the first edition of hisExtraordinary Popular Delusions and the Madness of Crowds. I want to discuss a contemporary moral epidemic: the notion that increasing atmospheric concentrations of greenhouse gases, notably carbon dioxide, will have disastrous consequences for mankind and for the planet. The “climate crusade” is one characterized by true believers, opportunists, cynics, money-hungry governments, manipulators of various types—even children’s crusades—all based on contested science and dubious claims.

I am a strong supporter of a clean environment. We need to be vigilant to keep our land, air, and waters free of real pollution, particulates, heavy metals, and pathogens, but carbon dioxide (CO2 ) is not one of these pollutants. Carbon is the stuff of life. Our bodies are made of carbon. A normal human exhales around 1 kg of CO2 (the simplest chemically stable molecule of carbon in the earth’s atmosphere) per day. Before the industrial period, the concentration of CO2 in the atmosphere was 270 ppm. At the present time, the concentration is about 390 ppm, 0.039 percent of all atmospheric molecules and less than 1 percent of that in our breath. About fifty million years ago, a brief moment in the long history of life on earth, geological evidence indicates, CO2 levels were several thousand ppm, much higher than now. And life flourished abundantly.
