Baseball players are hitting more home runs. Is it sheer talent, or warmer air?
First, a little physics lesson. As air gets hotter, it becomes less dense. Temperature is really, on a molecular level, about how much energy particles have—how much they vibrate and bounce around. As air molecules get hotter and more energetic, they move around more, collide and repel more, spreading each other thinner and thinner.When a baseball is slicing through the air, what it’s really doing is pushing particles of gas out of the way.
in a phone call with Earther. Nathan was not involved in the new research but has studied temperature and home run rate before., Nathan’s own models produced a thermal degree/home run rate relationship very similar to the one identified by the new research, but using different methods. He found that a 1 degree Fahrenheit change leads to about a 1% boost in home run number—converted to Celsius, it’s basically a dead-on match.
The new research notes that climate change-related homers accounted for only about 1% of the season total in 2019. Nonetheless, the influence of climate change on the sport is a significant, detectable signal that has far-reaching implications for how our fossil fuel reliance could impact a dear tradition, said Nathanial Dominy, an anthropologist at Dartmouth College and one of the authors of the new study, in a phone call with Earther.This is a story about baseball.
