The unborn may control global warming

A 10 year study out of the Queensland University of Technology has linked the proximity of air pollution to the shrinking size of the fetus, in particular, abdominal and head circumference and femur length. The ultra-sound scans of 15000 pregnancies were studied, though why someone got money for this I don't know.

So they are reporting that as air quality declines, so does the size of the fetus. This was done by measuring the distances the pregnant mothers lived from high levels of air pollution. Interesting discovery, but let's look at this another way, just to show how such studies can be flawed.

Let's say a young woman lives near a source of very poor air quality. What might we say about her? Perhaps she has little income or is not so bright because we would hope she would have moved away from there long ago. Perhaps she is unwed and quite poor or the daughter of a steel worker. Would she be of average or better intelligence, have a good health plan or the funds to afford a good doctor, eat well and exercise, have the support of other bright, affluent mothers-to-be... if she lived near such a place? I think not.

Australia spends less on health care than both the US and Canada, and the doctors apparently have no cap on billing, so, assuming this information coincides with the study, it stands to reason that the unfortunate mothers, living in less than favourable, polluted cities, might not be in the best health. Furthermore, the poor, unwed moms may have had more babies in the 10 years studied, skewing the figures even further.

That pollution itself causes the decrease in fetus size may be a convenient coincidence. Rather, I'd like to think that a) nature is finding a way to make more of us fit on this shrinking planet, or b) that a race of smaller infants is causing global warming.
