As the number of extreme heat days stretches later into the fall, many of the nation’s schools are seeking ways to adapt, but they’re often hindered by aging infrastructure and cuts to federal funding for climate upgrades.

Installing air conditioning or adding shade canopies to vast expanses of asphalt are effective but may come with red tape and a high price tag, said V. Kelly Turner, associate director of the UCLA Luskin Center for Innovation.

“A lot of our schools are older and probably in need of modernization,” Turner told Time magazine. “And climate change is casting some light on the fact that they really are underfunded to do that.”

Treating schools as community centers is one strategy that could be beneficial around the country, said Turner, an associate professor of urban planning at UCLA Luskin.

“If it’s really hot, some schools just send kids home, but what if a child is going home to a home that has no air conditioning? Now we’ve sent them to a place that’s maybe just as unsafe,” she said. “But if schools are seen as more like community centers and resource hubs, then we can provide all-day-long air conditioning to 25% of the population in one site in the community.”
