Climate crisis causing more home runs in baseball, study suggests

Data from 100,000 US Major League games reveals higher temperatures lead to more balls hit out of park

Steroids once gave many of baseball’s sluggers a power boost. Now research suggests that today’s home run hitters are seeing their shots turbocharged by the climate crisis.

A study by researchers at Dartmouth College in New Hampshire used data from 100,000 Major League Baseball games and 220,000 individually hit balls to show that higher temperatures increase the number of balls hit out of the park.
