Well, that's one I hadn't heard before!
Perhaps we can hope for a volcanic eruption in the area of the Dean Dome and then a permanent cloud/ash cover to diminish the sun's effects in Durham?
FWIW: It's been many a year since I endured a (daytime) game on the visitor side. And permanently etched into my brain is a near heat-stroke experience or two from sitting there for two days during the USA/USSR track meet way back in the days of the dinosaurs, perhaps even BEFORE any global warming had occurred. (And it was also deemed a blessing to have metal seating as opposed to the older wooden seats which necessitated careful attention to remove any splinters from one's backside.)
