Climate Change Boosts Home Runs, Study Finds.

A new study by Dartmouth College scientists has found that climate change is contributing to an extra 50 or so home runs a year in Major League Baseball. Hotter, thinner air that allows balls to fly farther contributed a tiny bit to a surge in home runs since 2010. Both the Dartmouth team and University of Illinois physicist Alan Nathan found a 1% increase in home run likelihood with every degree the air warms. Non-climate factors contribute even more to the barrage of balls flying out of the park, scientists and baseball veterans said.
