The 2022 World Cup will be played in Qatar. The NY Times reports that Qatar is hot during the summer. Anticipating that soccer players are less productive running around in 115 degree heat for 90 minutes, there is now a proposal to move the World Cup to the cooler months of November and December. Talk about adaptation! There are lots of folks complaining that this change in plans interferes with existing league schedules. I don't really care but this is a nice case study of how we adapt. There are many margins of adjustment including this one. This "solution" did not require a lot of ingenuity. It is no accident that Singapore springs into life at around 9pm as it gets cooler and everyone heads outside.
