That is interesting! However, the costs of air conditioning is raising a generation who is unable or unwilling or doesn't know how to acclimate to temperature change.
One has to assume that the students whose scores were hurt by long-term heat exposure WERE acclimated to the heat they had been experiencing. This feels kind of like the old "this generation is a bunch of weak whiners" excuse that we as a society like heaping on generations that follow our own.
It would certainly be better for the Earth to use less a/c. But it would be EVEN BETTER for everyone if we simply used electricty that wasn't generated in an earth-destroying way, AND made spaces where kids (and everyone else) could generally be comfortable enough to be at their best.
