Pittsburgh Beats Out Los Angeles as U.S. City With Worst Air Pollution

Harold D. Miller helpfully points out how wrong the ALA’s claims are in his article: Misleading Headlines on Air Quality, Yet Again

To summarize: ALA figures are from a single monitor (that is not in Pittsburgh) near a coke production plant that is twice as high as monitors actually in Pittsburgh. Worse still, the ALA fails to point out the source of even these emissions… 80% of which is from states upwind of Pittsburgh.

Better still: they first pulled this stunt in 2006, and yet they continue to ignore the problems with their report.

Ignorantly relying on bad science is one thing, willfully using bad science is another.  Those responsible for this are betraying all those who sincerely donated their time and efforts and who thought they were fighting for a noble cause.  The ALA should be ashamed.
