Host Dr. Lee F. Ball visits with climate scientist and Appalachian geography and planning professor Dr. Baker Perry. Perry shares details about his recent trip to Mount Everest to install the world's highest weather station, the applications of the data being collected at the station and even a little about his time playing basketball under Duke's coach K.
TranscriptAnnouncer: Define sustainability. Odds are your definition is completely different from the next person's. Appalachian State University's Director of Sustainability, Dr. Lee Ball, sits down with his guest to explore the many ways in which sustainability affects our lives. This is Find Your Sustainability.
Lee Ball: On today's podcast I'm here with Baker Perry. Baker is a professor in the Department of Geography and Planning here at Appalachian State University. I invited Baker to today's podcast because I'm really interested in you hearing about his work in climate science related to tropical glaciers in South America, and more recently his adventure to the Himalayas, installing a weather station on the highest mountain in world, Mt. Everest.
Lee Ball: Thank you so much for being here.
Baker Perry: Well, it's a real pleasure to be here, Lee. Thank you for the invitation.
Lee Ball: Baker, you've spent a whole career working in climate science, in that realm, working on glacier research in far-flung places around the world. And most recently you were on an adventure on Mt. Everest. What I'd love for you to share with our listeners is just a quick summary of how you get invited to be a part of that team, and how long you were there. And then I just have a few more questions to follow up.
Baker Perry: No, great question. Looking back, this all happened relatively quickly. It was about a year ago that the official invitation came about from National Geographic and this happened in conjunction with a close colleague, Paul Majewski, who we had here on campus about a year and a half ago, and he's somebody that I had been collaborating with the last couple of years on ice core paleoclimate research project in Peru. And he was tasked by National Geographic to lead the expedition, be the science lead for it.
Baker Perry: And so as a result of that, he had a little bit of latitude on people he could invite to participate, and obviously that had to be cleared by National Geographic. But based on our experience working together and in particular my role in installing and maintaining a network of weather stations in Peru and Bolivia, there was an opportunity for me to join the team and really take a lead on the planning and the installation of the weather station network on Mt. Everest. And so this was a bit of an unanticipated move, perhaps, from the Andes where I've spent so much of my career, and even life before my professional career to the Himalayas.
Baker Perry: But it was a region that I was not entirely unfamiliar with either. I had been to the Everest region, to Nepal about 20 years ago when I was a graduate student, so I had some familiarity with it. And of course, there's, you know, for a lot of us that study the highest mountains and weather processes, extreme weather and snow and ice, there's always a certain degree of fascination with the Himalayas, and in particularly Everest. And so the opportunity to participate in an interdisciplinary scientific expedition with National Geographic was pretty exciting to say the least.
Lee Ball: I'm guessing that the data that will be retrieved, that this weather station's going to be used in a wide variety of ways.
Baker Perry: They are. The data have lots of applications. We're working on several publications right now with direct applications on improving the forecasting on Mt. Everest. The models, what we found are pretty good up there, especially in the short term, but we can make them better and we can improve those forecasts and so we're demonstrating that.
Baker Perry: We're also improving the data that go into the glacier ablation models or the melt models, that are used to predict future glacier extent in the region and water resources. And so that's a direct application.
Baker Perry: And over the longer term we hope to have a much better understanding of the subtropical jet stream. This is one of the few places in the world where the surface interacts with the jet stream. And so that's a unique opportunity to study its behavior. Clearly there are other data sources that are available too, from weather balloons and aircraft flying in them but this is a unique dataset that's right from the surface of some of the highest places in the world.
Baker Perry: And then ultimately our team also recovered an ice core from the South Col in the highest ice core in the world. And so we really think that the weather stations will help us in the interpretation of the ice core as well.

The Burden
The Burden is a documentary series that takes listeners into the hidden places where justice is done (and undone). It dives deep into the lives of heroes and villains. And it focuses a spotlight on those who triumph even when the odds are against them. Season 5 - The Burden: Death & Deceit in Alliance On April Fools Day 1999, 26-year-old Yvonne Layne was found murdered in her Alliance, Ohio home. David Thorne, her ex-boyfriend and father of one of her children, was instantly a suspect. Another young man admitted to the murder, and David breathed a sigh of relief, until the confessed murderer fingered David; “He paid me to do it.” David was sentenced to life without parole. Two decades later, Pulitzer winner and podcast host, Maggie Freleng (Bone Valley Season 3: Graves County, Wrongful Conviction, Suave) launched a “live” investigation into David's conviction alongside Jason Baldwin (himself wrongfully convicted as a member of the West Memphis Three). Maggie had come to believe that the entire investigation of David was botched by the tiny local police department, or worse, covered up the real killer. Was Maggie correct? Was David’s claim of innocence credible? In Death and Deceit in Alliance, Maggie recounts the case that launched her career, and ultimately, “broke” her.” The results will shock the listener and reduce Maggie to tears and self-doubt. This is not your typical wrongful conviction story. In fact, it turns the genre on its head. It asks the question: What if our champions are foolish? Season 4 - The Burden: Get the Money and Run “Trying to murder my father, this was the thing that put me on the path.” That’s Joe Loya and that path was bank robbery. Bank, bank, bank, bank, bank. In season 4 of The Burden: Get the Money and Run, we hear from Joe who was once the most prolific bank robber in Southern California, and beyond. He used disguises, body doubles, proxies. He leaped over counters, grabbed the money and ran. Even as the FBI was closing in. It was a showdown between a daring bank robber, and a patient FBI agent. Joe was no ordinary bank robber. He was bright, articulate, charismatic, and driven by a dark rage that he summoned up at will. In seven episodes, Joe tells all: the what, the how… and the why. Including why he tried to murder his father. Season 3 - The Burden: Avenger Miriam Lewin is one of Argentina’s leading journalists today. At 19 years old, she was kidnapped off the streets of Buenos Aires for her political activism and thrown into a concentration camp. Thousands of her fellow inmates were executed, tossed alive from a cargo plane into the ocean. Miriam, along with a handful of others, will survive the camp. Then as a journalist, she will wage a decades long campaign to bring her tormentors to justice. Avenger is about one woman’s triumphant battle against unbelievable odds to survive torture, claim justice for the crimes done against her and others like her, and change the future of her country. Season 2 - The Burden: Empire on Blood Empire on Blood is set in the Bronx, NY, in the early 90s, when two young drug dealers ruled an intersection known as “The Corner on Blood.” The boss, Calvin Buari, lived large. He and a protege swore they would build an empire on blood. Then the relationship frayed and the protege accused Calvin of a double homicide which he claimed he didn’t do. But did he? Award-winning journalist Steve Fishman spent seven years to answer that question. This is the story of one man’s last chance to overturn his life sentence. He may prevail, but someone’s gotta pay. The Burden: Empire on Blood is the director’s cut of the true crime classic which reached #1 on the charts when it was first released half a dozen years ago. Season 1 - The Burden In the 1990s, Detective Louis N. Scarcella was legendary. In a city overrun by violent crime, he cracked the toughest cases and put away the worst criminals. “The Hulk” was his nickname. Then the story changed. Scarcella ran into a group of convicted murderers who all say they are innocent. They turned themselves into jailhouse-lawyers and in prison founded a lway firm. When they realized Scarcella helped put many of them away, they set their sights on taking him down. And with the help of a NY Times reporter they have a chance. For years, Scarcella insisted he did nothing wrong. But that’s all he’d say. Until we tracked Scarcella to a sauna in a Russian bathhouse, where he started to talk..and talk and talk. “The guilty have gone free,” he whispered. And then agreed to take us into the belly of the beast. Welcome to The Burden.
