Off the Radar

For more than a century, the Winter Olympics have depended on cold, reliable conditions. But as the planet warms, that foundation is becoming harder to find. As the Games return to Northern Italy, this episode of Off the Radar examines how climate change is reshaping the future of winter sports. Meteorologist Emily Gracey speaks with Dr. Daniel Scott of the University of Waterloo, whose research shows a rapidly shrinking list of cities capable of hosting the Winter Olympics safely and fairly. We explore why warmer temperatures mean more than just artificial snow, how deteriorating snow and ice increase risks for athletes, and why the Paralympic Games face even steeper challenges as competition moves deeper into warmer months. With fewer cold places left on the map, the question is no longer theoretical. Can the Winter Olympics survive in a warming climate, and what decisions made today will determine their future?

Climate science is most often communicated through charts, graphs, and visual models. But data does not have to be seen to be understood. In this episode, meteorologist Emily Gracey explores how climate data can be translated into sound. Emily is joined by mathematician and musician Harlan Brothers, who creates climate sonifications by converting real datasets into music and audio you can hear. Using measurements such as global temperature over land, sea surface temperatures, and sea level rise, Harlan turns long term warming trends into melodies that reveal patterns over time. The conversation looks at how sonification works, why sound can engage people differently than visuals, and how music can add a new dimension to climate communication without compromising scientific integrity. Throughout the episode, listeners will hear examples of these climate sonifications woven into the discussion, offering a chance to experience climate data through a different sense.

When catastrophic flooding hits, we usually look at rainfall totals and records broken. But what if the most important number comes before the rain ever starts? In this episode, meteorologist Emily Gracey explores a groundbreaking Washington Post investigation that reveals how massive flows of atmospheric moisture are intensifying across the globe, creating hotspots that turn storms into deadly floods. Using a powerful metric called Integrated Vapor Transport (IVT), the reporting shows that the real story isn't happening on the ground...it's happening way above our heads. Emily sits down with Washington Post meteorologist Ben Noll, who spent a year analyzing the data behind "Deadly Rivers In The Sky." Together, they unpack how rising global temperatures have supercharged the movement of moisture through Earth's atmosphere, why certain regions now face grave risks of extreme rainfall, and what this means for communities from Appalachia to Spain. Floods can be sudden, devastating, and hard to recover from. But what if the real story isn't just the rain that falls, but the moisture in the sky that never used to be there?

It's been a monumental year, both for weather and for Off the Radar. From Hurricane Melissa's record-breaking assault on Jamaica to devastating Texas floods, from NOAA layoffs to groundbreaking AI forecasting models, 2025 reminded us how powerful and vulnerable we are when it comes to our changing climate. In this special year-end episode, host Emily Gracey sits down with associate producer Brian Pietrus to count down their favorite episodes of 2025. They revisit the conversations that stuck with them, the research that blew their minds, and the projects that deserve far more attention. It's also been an award-winning year for the podcast. Off the Radar took home a national Headliner Award for Best Information Podcast, and Emily Gracey won the Women's Podcast Award for Best Science Podcast Host! Stay tuned until the very end to hear Emily's absolute favorite project of the year - the moment that resonated most in a year of extraordinary science and storytelling.

The Drake Passage, a 600-mile stretch of ocean between South America and Antarctica, is one of the most dangerous bodies of water on Earth. With waves that can exceed 40 feet and a history littered with shipwrecks, it's claimed the lives of an estimated 10,000 sailors. Yet today, thousands of tourists willingly cross it every year on their way to Antarctica, documenting the experience with hashtags like #DrakeShake and #DrakeLake. In this episode, we explore what makes the Drake Passage so treacherous and why it's become a rite of passage for modern adventurers. Travel influencer Alyssa Ramos, who has crossed the Drake eight times, shares what it's really like aboard a ship battling these notorious waters. Then, marine meteorologist Alvaro Scardilli from the Argentine Navy breaks down the atmospheric forces and ocean dynamics that create some of the most volatile conditions on the planet. From its days as a ship graveyard to its current status as a bucket-list destination, this is the story of the Drake Passage.

In the 1930s, the Great Plains transformed from a land of promise into an apocalyptic landscape of suffocating dust storms. For nearly a decade, massive black clouds swept across 150,000 square miles of Oklahoma, Kansas, Texas, Colorado, and New Mexico, turning day into night and forcing families to abandon their homes. Dust storms lasted for days at a time, reducing visibility to zero. People coughed up clumps of earth and developed "dust pneumonia," while livestock died with inches of dirt lining their digestive tracts. But how did this happen? And more importantly, could it happen again? We speak with Dr. Jeff Lee of Texas Tech University and Dr. Thomas Gill of the University of Texas at El Paso to explore the causes of this catastrophic period in American history, how the Dust Bowl reshaped the nation, and what vulnerabilities we still face today.

Dr. David Beuther, a pulmonologist, reveals how climate change is creating a quiet respiratory health crisis - one where patients with lung disease are increasingly trapped indoors by poor air quality. In this conversation, we explore the growing impact wildfire smoke, extended pollen seasons, and shifting weather patterns are having on our ability to breathe. Dr. Beuther shares practical strategies for protecting lung health, from choosing the right air filters to understanding air quality forecasts, and discusses how he advises patients about the connection between climate change and their symptoms. This isn't a distant environmental threat; it's happening now, in doctors' offices and homes across the country, affecting millions of people who just want to take a breath of fresh air.
