How climate change is affecting America's pastime

Major League Baseball's Opening Day is Thursday and while box scores will once again light up across the country, one stat fans won't see on scorecards is how climate change has affected the game. 

Over the last 50 years, the average temperature in cities with MLB teams has warmed 2.1 degrees Fahrenheit, according to findings published Wednesday by nonprofit news and science organization Climate Central. That figure fluctuates to as much as a 5.2-degree increase for the Toronto Blue Jays, and tenth of a degree of cooling in Oakland for the Athletics.  That warming affects the game. Not only does it put players — and fans — under more heat-related stress, it has led to more rain delays and rainouts.
