To the untrained eye, Arctic ice appears unchanging, but conditions can shift quickly, and often reveal life-threatening hazards when they do. It is an unforgiving environment, but the Inuit know how to navigate it. That knowledge has been passed down through generations, and a new app is giving centuries-old Inuit knowledge a very modern form.

Brian Huber is a climate detective at the Smithsonian who grew up collecting arrowheads in the woods of Ohio, but now collects and studies fossils from sediment cores. Brian uses fossils of tiny organisms − foraminifera − to track climate over millions of years, including the Cretaceous Hot Greenhouse climate.

Anant Pande is an Indian polar researcher who studies snow petrels – shy pelagic (sea-faring) birds who nest on rock crevices in Antarctica. These endemic birds prefer to nest near less icy waters. Climate change has melted polar oceans and perhaps made it less energy intensive — as they have to fly shorter distances to find non-frozen oceans.

For many of us, the word “extinctions” conjures up images of dinosaurs, asteroids, and (maybe?) volcanos. And while that last point did likely play a role in the demise of the dinosaurs, volcanos in their own right can go extinct. In this episode, we chatted with volcanologist Janine Krippner, Honorary Research Associate at the University of Waikato, about what exactly makes a volcano extinct, the difference between volcanic ash and smoke, …

When you hear the word “extinction,” chances are you probably think of the extinction of the dinosaurs and a big rock. But did you know that there were other factors at play that lead to that extinction including volcanos and sea-level rise?

Emily Williams has traveled the world in search of birds. As a biologist, she’s worked in Kansas, Argentina, Australia, and Denali, and studied loons, flycatchers, kingbirds, and more. And even with all these experiences and diverse species interactions, she’s now landed (ha, get it?!) on studying the common robin.

Pacifica Sommers is an ecologist and explorer. From the deserts of Arizona to the Antarctic tundra, Pacifica has looked at how organisms from tardigrades to pocket mice live in extreme environments. We talked with her about some of the most beautiful places on Earth, the diversity of folks who can be scientists, and what exactly that bucket is for on the flight to Antarctica.
