In this first installment of a two-part series, we are exploring the changing face of Mount Everest through the experiences of Scott Thuman, news anchor at 7 News Washington, DC, who trekked beyond Everest's base camp. Through Thuman's account, you'll learn about the brutal conditions of high-altitude hiking – from the oxygen-starved air to the punishing winds and subzero temperatures – while discovering how climate change is transforming this iconic landscape. We'll examine the increasingly unstable Khumbu Glacier and what these changes mean for the future of high-altitude mountaineering, setting the stage for Part 2's upcoming discussion with a glaciologist studying these dramatic transformations.

Have you ever wondered how tsunamis are detected? We recently spoke with a survivor of the 2004 Indian Ocean tsunami. This week we’re talking with Dr. Stuart Weinstein, Deputy Director of the Pacific Tsunami Warning Center. We’ll discuss the tsunami warning system, emergency evacuation, and why the 2004 tsunami was so deadly. We’ll also cover the possibility of a freshwater tsunami in the Great Lakes, and the science behind tsunami formation and detection.

A massive 9.1 magnitude earthquake under the ocean. A series of tsunami waves moving almost 500 miles an hour. Nearly a quarter of a million people dead across 14 countries. Today we’re going off the radar to talk about one of the largest seismic events ever recorded: the 2004 Indian Ocean earthquake and tsunami, also known as the Boxing Day Tsunami. My guest this week is marine biologist Dr. Dwayne Meadows. He was in coastal Thailand when the deadliest tsunami in history came crashing in, and he was almost a victim of its destructive power. Dwayne was swept out to sea by its powerful waves – and despite the odds, he survived. We’ll be discussing this harrowing event, how to vacation safely along coastal areas, and the impact a tsunami can have on a survivor’s mental health.

You may have heard the term “atmospheric river” in recent years – but what does it mean? Did you know that it’s literally akin to a river in the sky? Or that they carry water vapor content that’s comparable to twenty-five Mississippi Rivers? Today we’re going Off The Radar to discuss ARs with the scientist that put this weather phenomenon on the map. Dr. Marty Ralph is the Director of the Center for Western Weather and Water Extremes at the Scripps Institution of Oceanography. We’ll be diving into the ways the West Coast gets their precipitation, how we rank them, and the impact they have on weather across the globe.

You probably think you’ve heard the story of the first Thanksgiving – but did you know that the weather was a major factor in both the Pilgrims leaving England, and landing at Plymouth Rock? Or that trees can tell us what the weather was actually like during the winter of the first Thanksgiving? This week we’re going Off the Radar with Paleo-Climatologist Dr. Curt Stager and Historian Rebecca Fraser to learn the real story of the first Thanksgiving in American history. Put away the leftover turkey and settle in for a history lesson over 400 years in the making!

November 20, 1998 marked the launch of the first module of the International Space Station. Over time, the ISS grew to be the size of a football field, circling the globe every 90 minutes at 17,500 miles per hour. Today we are joined by NASA Astronaut Dr. Stan Love. Stan was part of the team that got the ISS up into orbit and will play a crucial role in bringing it back down to Earth. We'll discuss the important work that's been done over the past 25 years and why it's now time for the mission to end. We'll also look ahead to the next steps in the Artemis program as NASA transitions out of low-Earth orbit and into Deep Space!

Atop New Hampshire's 6,288-foot Mount Washington, weather observers have studied the "world's worst weather" for decades. The invaluable data from this natural laboratory has shaped modern meteorology and has aided weather prediction, aircraft design, and engineering. Join us as we sit down with former Mount Washington observer (and current WGME Chief Meteorologist) Charlie Lopresti to explore this remarkable peak where future meteorologists find inspiration, weather records are shattered, and nature reveals the raw power of our atmosphere.
