Australian Government Climate Scientist: Carbon Warming Too Minor to Be Worth Worrying About
By Mary Theroux • Monday May 30, 2011 3:28 PM PST •
A self-described former climate alarmist, now skeptic, Dr. David Evans served as a full-time consultant for the Australian Greenhouse Office (now the Department of Climate Change) from 1999 to 2005, and part-time from 2008 to 2010, modelling Australia’s carbon. He is a mathematician and engineer, with six university degrees, including a Ph.D. from Stanford University in electrical engineering.
Dr. Evans recently proclaimed:
The debate about global warming has reached ridiculous proportions and is full of micro-thin half-truths and misunderstandings.
Among other questions Dr. Evans poses: “Why does official science track only the surface thermometer results and not mention the satellite results?”
As the work of Independent Institute Research Fellow Dr. S. Fred Singer also shows, Dr. Evans notes that it’s to conceal the truth of actual change in global temperatures:
One way they conceal is in the way they measure temperature.
The official thermometers are often located in the warm exhaust of air conditioning outlets, over hot tarmac at airports where they get blasts of hot air from jet engines, at waste-water plants where they get warmth from decomposing sewage, or in hot cities choked with cars and buildings.
The whole idea that carbon dioxide is the main cause of the recent global warming is based on a guess that was proved false by empirical evidence during the 1990s. But the gravy train was too big, with too many jobs, industries, trading profits, political careers, and the possibility of world government and total control riding on the outcome. So rather than admit they were wrong, the governments, and their tame climate scientists, now outrageously maintain the fiction that carbon dioxide is a dangerous pollutant.
When the carbon dioxide theory was posited in 1980, scientists guessed that every bit of warming caused by increased levels of carbon dioxide would be “multiplied” up to three times by creating extra moist air. Yet although this “multiplier effect” has been proven as flawed as the Keynesian multiplier, neither theory apparently will die.
At this point, official “climate science” stopped being a science. In science, empirical evidence always trumps theory, no matter how much you are in love with the theory. If theory and evidence disagree, real scientists scrap the theory. But official climate science ignored the crucial weather balloon evidence, and other subsequent evidence that backs it up, and instead clung to their carbon dioxide theory—that just happens to keep them in well-paying jobs with lavish research grants, and gives great political power to their government masters.

Finally, to those who still believe the planet is in danger from our carbon dioxide emissions: Sorry, but you’ve been had. Yes, carbon dioxide is a cause of global warming, but it’s so minor it’s not worth doing much about.
