I present the first sentence of an April 7, 2023 Associated Press report:
Climate change is making major league sluggers into even hotter hitters, sending an extra 50 or so home runs a year over the fences, a new study found.
There was a craze in the early 2000s about steroid use in baseball which likely played more than a small factor in some dramatic individual home run totals. I am sure that some of the dramatic personae who had the misfortune of having used steroids right around when sports journalists briefly took an interest in the subject would have appreciated this study having existed at the time. Not only could you attribute a massive single-season jump in your home run out to unusually warm temperatures on game days, but you could also explain physical changes: “I don’t think my head and neck are growing, but it is possible that they are expanding due to recent unseasonably warm temperatures in the area.”
