Baseball and climate change

A team from Dartmouth University, in conjunction with Major League Baseball (MLB) has reported that the increase in average temperatures has led to an increase in home runs per year (50) since 2010  and 1% increase in the likelihood of home runs for every degree increase in temperature. Global warming is juicing the baseball. The increase in temperature decreases air density which in turn reduces aerodynamic drag on the baseball, allowing the ball to travel farther. Last year’s catch on the warning track is now more likely to clear the wall. This bit of scientific sports trivia was provided in this Friday’s bulletin of the American Meteorological Society.
