In the FRONTLINE documentary Alaska’s Vanishing Native Villages, residents of a coastal Alaska Native community called Hooper Bay confront a dilemma.

Their way of life relies in part on harvesting food directly from the sea. But as the documentary explores, flooding, erosion, warming temperatures and thawing permafrost are forcing conversations about relocating to higher ground.

“This climate change thing is wreaking havoc,” says Agatha Napoleon, the climate change coordinator for one of the Alaska Native tribes that lives in Hooper Bay.

Alaska’s Vanishing Native Villages, a collaboration with the Howard Center for Investigative Journalism at Arizona State University, premiered on April 22, 2025. The following month, FRONTLINE aired a new joint investigation with NPR, Hurricane Helene’s Deadly Warning. Building on a decade of reporting on disasters and their aftermath, the documentary investigates how Helene — whose floods caused death and destruction even in inland, elevated areas — became an ominous warning about America’s lack of preparedness for climate change-related storms.

These two films are the latest installments in FRONTLINE’s years of documentaries on the science, politics and impact of climate change — from early research into climate change by fossil fuel companies, to the organizations that fought the scientific establishment to shift the climate conversation in the U.S., to the role of climate change in deadly American wildfires.
