The Fraser Institute recently issued a report on Canadian air quality that achieved moderate coverage, but little critical scrutiny (apart from a devastating critique from the Suzuki Foundation). In Canadian Environmental Indicators – Air Quality, Fraser Senior Economic Researcher Joel Wood claims that concentrations of five major pollutants, including the particularly worrying duo of fine particulate matter and ground level ozone, are in decline. Wood even accuses ENGOs and the Canadian Medical Association of trying to “scare” the public with claims that are “exaggerated or outright wrong”, particularly in their concerns about ozone.
But in a shocking development (or perhaps not), it turns out that Environment Canada’s official air quality indicator for ozone shows a statistically significant worsening over the last two decades, while both fine particulate matter and ozone show no significant trend in the last decade. The Environment Canada indicators, the very existence of which appears to have been totally missed by Wood and the various reviewers of his work, are based on complete warm season averages weighted by population, and thus provide a much better indicator than Wood’s ad hoc analysis.
This same ineptitude can also be seen in Wood’s short climate policy analyses, where he gets the basics totally wrong, while questioning the validity of climate science itself. Thus the ignorance, incompetence and bias of Canada’s self-styled “leading public policy think tank” is demonstrated once again.
