How do you protect yourself from wildfire on a warming planet? You burn everything on purpose. No, seriously. Thanks to climate change, the whole world is a tinderbox. Fire season now starts sooner and ends later, and scientists say lightning will become more frequent, and winds more powerful. Our only defense may be intentional fires. In this episode, our friends at Outside/In take a close look at the ecology of prescription burns. Why are our forests so dependent on wildfires? And why did some plants evolve to become more flammable?

There are between eight and ten thousand wildfires in the United States each year, but most quietly burn out, and we never hear about them. The Pagami Creek Wildfire in Minnesota’s Boundary Waters Canoe Area was supposed to be like that. It was tiny and stuck in a bog that was surrounded by lakes. It was the kind of fire you could ignore. Computer models predicted that it would just sit there. But those models didn’t account for a rare convergence of atmospheric events had prepped the forest for an unprecedented burn. And Greg and Julie Welch were camping right in its path. In the first of four episodes investigating American wildfires, we tell the Welch’s extraordinary story and look at the factors that lead to this unexpected blaze.

Carina Hoang grew up in a wealthy family in Vietnam. She had a nanny to take care of her and a maid who cleaned up after her—she didn’t even wash her own hair. But when the Vietnam War broke out, she and two siblings fled the country on a boat, landing on Kuku beach, in Indonesia. It was supposed to be a refugee camp, but it was actually a deserted island. No food, no water, no buildings, people, or tools. Just sand and jungle. Produced in collaboration with Snap Judgment, with funding from the International Women’s Media Foundation, this is a story about Carina’s decades-long struggle to leave Kuku Island behind.

Most of the time, when lightning makes the news, it’s because of something outlandish—like the park ranger who was struck seven times, or the survivor who also won the lottery (the chances of which are about one in 2.6 trillion), or the guy who claimed lightning strike gave him sudden musical talent. This is not one of those stories. This is about Phil Broscovak—who was struck by lightning while on a climbing trip with family in 2005—and the confounding, bizarre science that can’t fully explain what Phil and other survivors endure in the aftermath of a strike. Originally broadcast in 2016, this episode is one of our favorites.

Everyone gets older, but not everyone bows out of competition in middle-age. Journalist Jeff Bercovici wanted to know: Why? Why do some athletes flame out in their 30s and 40s, while others are still going as senior citizens? Is it genetics? Special training? Diet? And could amateur athletes achieve similar results? Outside editor Chris Keyes talks with Jeff about his new book, Play On: The New Science of Elite Performance at Any Age, and what it takes to reverse the effects of getting older.

Climbing was Shelma Jun’s fallback sport. A snowboarder and mountain biker, she found her way into a climbing gym after injuring her shoulder and looking for an activity where she wouldn’t risk more impact. As a friend told her, you can’t fall very far if you’re attached to a rope. In 2014, she created an Instagram account called Flash Foxy to celebrate the crew of hard-charging New York women she’d begun climbing with. After gaining thousands of followers, she co-founded the Women’s Climbing Festival, which sold out in under a minute last year. In our final installment of this series looking at inclusivity in outdoor communities, James Edward Mills spoke to Jun about the influence a rising generation of female athletes is having on a sport long dominated by men.

Knox Robinson grew up watching his dad run and went on to race track himself at a Division I college, but he was never defined by the sport. He’s more of a renaissance man. For years, he gave up athletics, studying and living in Japan, then managing rock stars and rappers in New York City. It was only as an adult—and after having a son of his own—that he returned to running, eventually co-founding a running collective called Black Roses NYC. Grounded in New York street culture, the group seeks to build community and promote physical and mental health among black men and women. In this third installment in a four-part series looking at inclusivity in outdoor communities, Outside contributor James Edward Mills talks to Robinson about his journey, and how running through diverse urban neighborhoods can be a powerful way to project a message of vitality and togetherness.

Ayesha McGowan came late to competitive cycling. An accomplished violinist, she didn’t enter her first organized biking event until after college. Despite riding an old steel bike with a milk crate on the back and wearing jean shorts in a peloton of spandex, she impressed the other women, who encouraged her to start competing. A year later, she took fifth place in her first race, then kept winning on the amateur circuit. Now she’s aiming to be the first African American female cyclist on the pro tour, and gets closer to that goal every day. In this second installment in a four-part series looking at inclusivity in outdoor communities, journalist James Edward Mills sits down with McGowan to talk about her fast road to success.

When Mikhail Martin started climbing at a Brooklyn gym in 2009, he was one of very few African Americans to rope up. Today, his group, Brothers of Climbing, is working to change that. BOC is tackling diversity in rock climbing, which includes bridging the gaps in lingo, jargon, and etiquette that keep people of color out of the sport. Nobody understands these issues better than journalist James Edward Mills, author of The Adventure Gap, a book that looks at the challenges minority groups face when engaging in outdoor recreation. In this first episode in a four-part series looking at inclusivity in outdoor communities, Mills asks Martin about his personal journey and the progress he’s achieved with BOC, and where we go from here.

In 2014, the federal government rounded up Cliven Bundy’s cattle over a matter of unpaid grazing fees. So the Bundy family gathered a posse and took them back at gunpoint. Two years later, they took over the Malheur National Wildlife Refuge. The Bundys are making a habit of taking on the federal government and winning. For the past two years, reporter Leah Sottile has been following this story, trying to figure out what all this means for the future of public lands in the American West, and wondering what happens next?
