An oldie but a goodie about "Alisa Zinovievna Rosenbaum" a.k.a. Ayn Rand.
"A heavy smoker who refused to believe that smoking causes cancer
brings to mind those today who are equally certain there is no such
thing as global warming. Unfortunately, Miss Rand was a fatal victim
of lung cancer."
Not sure if I agree with the "Unfortunately" in that, but the rest of the article is fantastic reading.
