How is this even news? I'd think that century-old health data would make it bleedin' obvious that heavy air pollution increases the incidence of lung cancer.

A century ago, the idea that smoking causes cancer was quite new and was decades away from being conclusively proven.

Hardly new, In Sketches, Old and New by Mark Twain in 1893, he treats the concept of: smoking being dangerous, as obviously known but annoying and he doesn't want to hear about it.

Wikipedia says "In 1912, American Dr. Isaac Adler was the first to strongly suggest that lung cancer is related to smoking." but I guess there could be other less strong suggestions before then. Regardless, I think it is true that it wasn't conclusively proven until decades later, and then took some more time for the general public to be aware.
