When I was growing up in Orange County, So Cal, we used to regularly
get really serious pea soup fog, fog so thick you couldn't see more
than 20 or 30 feet in front of you. To cope with this when driving,
all the streets used to have sinusoidal lines painted along the
central divider for fifty feet or so before an intersection so you'd
know it was coming. That simply doesn't happen anymore and there
haven't been sinusoidal lines on streets for many decades.
I suspect this has less to do with global warming than with having
mowed down all the orange groves and built houses to accommodate the
six-fold increase in county population since those days. For some
reason that I really don't understand, nobody (except, perhaps, Al
Bartlett) seems interested in taking on the root problem of
overpopulation anymore. When I bring it up in my lefty circles, I'm
often greeted with either embarrassed silence or mild scorn for my
apparent vestigial racism.
