Opening day is tomorrow, and the baseball season is warming up due to climate change.
Since 1970, Major League Baseball (MLB) cities have warmed an average of 2.1°F during the baseball season. The greatest warming occurred in Toronto for the Blue Jays (warmed by 5.2°F) while the least occurred in Oakland, California for the Athletics (cooled by only 0.1°F).
As temperatures increase, so does the frequency of heavy rain events and bouts of extreme heat—weather conditions which can postpone games and impact the health of players and fans. And for baseball stats enthusiasts, it can also affect the probability of homeruns.
MLB has taken strides to become more green and sustainable in recent years, including LEED (Leadership in Energy and Environmental Design)-certified stadiums, LED field lights, solar energy use, and more.
