College is too expensive for students to waste money paying incompetent professors who teach the long discredited belief that carbon dioxide has a magical power to affect the temperature of the air. I recognize that some of the professors who push Enron’s global warming scam are crooked rather than incompetent. The science version of prostitutes will say science is whatever their employers want it to be.
The claim that slight changes in the amount of atmospheric CO2 could affect air temperature is based on a primitive early 19th Century belief that infrared radiation was “heat” and the atmosphere was heated by trapping it.. Physicists at the time had only a limited understanding of radiation, heat or atoms. For example, Jean Baptiste Joseph Fourier claimed in what is called the “greenhouse gas theory” that the earth was heated in part by the IR received from distant stars. Physicists would not learn until late in the century that heat is the kinetic energy of atoms and atoms are not the smallest particles of matter.
Radiation doesn’t heat the gas molecules in the atmosphere, but may heat dust and soot particles in the atmosphere. If IR heated the atmosphere then the high energy IR from the sun would heat the atmosphere much more than the low energy IR emitted by the ground. Physicist R. W Wood disproved Fourier’s theory in 1909. He used small greenhouses that were identical except that one reflected IR and the other was transparent to IR. There was no significant temperature difference. In the initial run of the experiment the greenhouse that was transparent to IR heated faster than the one that reflected IR because the reflective greenhouse reflected the high energy solar IR back into space. If CO2 reflects IR then increasing the amount of atmospheric CO2 should result in more solar IR being reflected back into space and thus reduced solar heating.
Warmer have yet to provide any proof that the process they talk about exists. Their pathetic attempt to prove their theory involves creating a mathematically worthless number they call “the global average temperature”.
The so-called global average temperature “is thermodynamically as well as mathematically an impossibility, says Bjarne Andresen, a professor at The Niels Bohr Institute, University of Copenhagen, who has analyzed this topic in collaboration with professors Christopher Essex from University of Western Ontario and Ross McKitrick from University of Guelph, Canada.”
“It is impossible to talk about a single temperature for something as complicated as the climate of Earth”, Bjarne Andresen says, an expert of thermodynamics. “A temperature can be defined only for a homogeneous system. Furthermore, the climate is not governed by a single temperature. Rather, differences of temperatures drive the processes and create the storms, sea currents, thunder, etc. which make up the climate”.
“While it is possible to treat temperature statistically locally, it is meaningless to talk about a a global temperature for Earth. The Globe consists of a huge number of components which one cannot just add up and average.”
Even if “the global average temperature” had mathematical value, an increase couldn’t prove an increase in atmospheric CO2 was responsible. Continued increases in the heat generated by human activity should be causing an increase in air temperature. The global warming alarmists don’t claim that an increase in the teracalories of heat humans collectively introduce into the air each day can cause dangerous global warming. . Instead they claim that unverified process that involves a gas that comprises only 0.04% of the atmosphere is the threat. These people shouldn’t be teaching college. They should be reading fairy tales in a day care center.
A normal person entering a room that is too hot and has a space heater operating at the highest setting and a small it birthday candle would turn off the space heater. The person would treat the candle as a decorative feature that didn’t add any significant amount of heat. The alarmist would blow out the CO2 producng candle and ignore the heater.
