This story originally appeared in Kids Today, Vox’s newsletter about kids, for everyone. Sign up here for future editions.A few summers ago, we signed our older kid up for a very outdoorsy camp. The organizers prided themselves on getting children comfortable with nature and the elements; they told us that kids would only go indoors if absolutely necessary.Then, a punishing heat wave hit New York City. Our kid came home with a weird heat rash that took days to go away. Later that summer, smoke from Canadian wildfires forced the camp to take shelter at a nearby school. My kid did not enjoy the experience, but I don’t blame the camp. Organizers around the country have had to change their programs or even cancel camp in response to extreme heat, smoke, and other realities of our modern summer. The result is often a loss of outdoor time, which is critical for kids’ physical health and social development. That loss is especially troubling at a time when recess is dwindling, and school is becoming increasingly screen-based. Kids need as much summer as they can get.It’s still possible to give campers the fun new experiences they need, experts say. But it takes a new layer of planning and adaptability as climate change, increasingly, factors into every decision.“Our focus really should be not on less outdoor activity,” Allison Poulos, an assistant professor at Arizona State University’s College of Health Solutions, told me. “It’s just smarter outdoor activity.”What kids lose when it’s too hot for campAs I’m writing this story, extreme heat warnings are affecting more than 160 million Americans as a “heat dome” closes over the Midwest and Northeast. In some parts of New York state, “feels like” temperatures are expected to go as high as 110 degrees.This is, sadly, our new normal. Higher average temperatures due to climate change are making heat waves more common and extreme. “When a heat dome or a high-pressure system sets up, it’s now starting from a hotter floor,” Ashley Ward, director of the Heat Policy Innovation Hub at Duke University’s Nicholas Institute, recently told NPR. “That makes the extreme heat more likely.”As we’ve seen during recent heat waves across Europe, extreme heat can be dangerous. Kids are especially vulnerable because their bodies heat up more quickly and are less efficient at cooling off by sweating, said Harleen Marwah, a pediatrician at Mass General Brigham for Children who has spent her career working on the intersection of climate and health.Children also don’t necessarily recognize when they’re getting too hot and may “push themselves to play to a point where they’re in an unsafe situation,” Marwah told me. “It really puts the onus on the caregiver to be monitoring closely.”In the face of triple-digit heat, sometimes organizers have no choice but to cancel camp. The recent heat wave has already led to cancellations in the Midwest.But calling off camp presents real childcare problems for parents, who typically have to work in the summer, no matter how hot it gets. It’s also not great for kids, who get real benefits from the outdoor playtime that camp can provide.Being outside is “an opportunity for physical activity, which is good for overall health, and also becoming increasingly limited as people spend more time indoors and more time behind screens,” Marwah said.Being in green spaces, especially, is good for kids’ mental and emotional wellbeing, Marwah said. “Outdoor play creates a space where children can learn about nature as well, and that’s an opportunity that gets missed out on if things have to be canceled.”How camp can survive climate changeWhenever possible, camps should adapt to the heat instead of completely cancelling activities, experts say. It’s a process Kevin Martin, director of recreational sports at Texas A&M Corpus Christi, knows well. Known as “Jambalaya” to the hundreds of campers who come to the campus every summer, Martin said this summer has already been punishing.“Man, it’s been hot,” he told me. “The mosquitoes have been biting.”But Texas A&M camps haven’t canceled or reduced their hours. Instead, the heat “has made us be more innovative,” Martin said.Even if other outdoor activities are canceled, the pool stays open, especially since swimming is “magnificent” for campers’ mental health, Martin said. But counselors enforce mandatory water breaks even during swim time.That’s crucial, Marwah said, because playing in water, while cooling in the short term, can actually mask the signs of dehydration.Beyond making sure campers get plenty of water, camps can also think about the design of their outdoor spaces, including using materials that heat up less quickly and creating space for shade, ideally from trees, Marwah said. That takes time and money, but one thing camps can do right now is structure their schedules with the forecast and heat index in mind, keeping outdoor activities in cooler parts of the day. When it’s just too hot to be outside, there are ways to keep kids active. Poulos and her team have found that playing in an indoor gym, with room to move around, offers some of the same benefits as outdoor play. At Texas A&M, campers retreat to the gym for dodgeball, Pop-A-Shot, and an introductory basketball game called Nukem. “I don’t know what is about Nukem, but they love Nukem,” Martin said.His campers have the benefit of being on a campus with college-level athletic facilities. But even camps with fewer resources can use what they have to support play on hot days. Camps with smaller indoor spaces, for example, can rotate kids between inside and outside so that everyone gets to play and no one gets too hot, Poulos said.All of this adaptation takes work — it’s one of the many burdens climate change is placing on communities around the world. But planning ahead is also an opportunity to help kids contribute to the solution.Martin likes to get campers’ input on games they want to play — as a member of Gen Z, he already feels out of step with what they’re into. “When you get their buy-in and ask them, ‘What do y’all enjoy playing? What do you want to play?’” he said. “They are [so excited for] the camp at that point, because they feel valued.”What I’m readingA new report says that the Department of Education may no longer be able to do its job of enforcing federal education law after the Trump administration cut 40 percent of staff and terminated $2 billion worth of contracts and grants in 2025. The report was incomplete because department staff did not comply with interview requests, meaning even internal investigators were unable to assess the full scope of the damage.The Texas State Board of Education has approved a required reading list for public school students that includes a Bible excerpt in most grades, sparking concern among teachers and advocates for the separation of church and state.The latest viral squishy toy is a stick of butter.My horror-loving older child enjoyed The Witch’s Wings and Other Terrifying Tales, a graphic novel based on that millennial mainstay Are You Afraid of the Dark?.Also in throwbacks, my little kid is now obsessed with Spider-Man and His Amazing Friends, a 1980s cartoon that predates even me. My older kid calls it “old-timey” and “ancient.”
