Coincidentally, the research in question had just run out of its funding.
How does this fit the profile for ecomyth creationism?
Well it deals with a "well-known" environmental health hazard (smog) that everyone knows is rising and now we have further "evidence" from vital (but no longer sponsored) research that shows residents are at "added" risk and where "the reality may be worse". So we have fear, escalation, supposition and the implied element of new science indicating catastrophe unless action is taken -- preferably against big bad SUVs and people who create smog by not cycling enough.
- The absence of context. North American studies show smog to be in serious decline over the past 20 years. What are the longitudinal data for London?
- The selective use of data and lack of description in the media of the study protocol. The sample of residents was only 60 and the data only showed "a slight correlation" in the preliminary analysis.
- The jump into fear and hype mode, with concomitant vagueness around possible and dire future consequences: at least in horror movies you can hear the sinister music being played in the background.
