AIR POLLUTION NOT TO BLAME FOR THOUSANDS OF DEATHS

This article exposes the fraudulent claims that air pollution is a major cause of death in modern cities.

Ross McKitrick, a University of Guelph economist, has taken a close look at the usefulness of the computer methods producing these smog death figures. First he took Toronto’s computer model and gave it data from the 1960s, when air pollution was noticeably worse than today. Back-testing is a common way to judge a computer model’s reliability. If it cannot explain what has already happened, then it’s usefulness in explaining the future is highly suspect.

The output was nonsense. In February 1965, for instance, the computer model claimed more people died from air pollution than died in the real world from all causes.

“The results I got suggest the models are implausible,” McKitrick told me. “They’re attributing over 100 percent of all deaths to air pollution. It just doesn’t make sense.”

Given the obvious flaws in existing computer models, McKitrick created his own simulation. With two Scottish academics he gathered 20 years of data from five Canadian cities – a far larger data set than used by the Ontario Medical Association – and performed a more sophisticated computer test. These results show air pollution to be almost entirely irrelevant to hospital admissions or death.

According to McKitrick, even if all forms of air pollution miraculously disappeared from Ontario over night, there would be no noticeable decline in the death rate. Claims of a massive death toll do not stand up to scrutiny.
