In 2013, Sarah Aciego came up with an idea while conducting field research on glaciers in Greenland. Her mother, Mindy Cambiar, is a photographer who had accompanied Aciego to document her team’s work. The pair discussed bringing tourists to Greenland and Iceland, where Aciego could explain climate change amid dramatic landscapes. Although Aciego had tried other forms of outreach, such as public lectures, their impact felt limited. “I felt like I was just talking to the same people,” says Aciego, then a glaciochemist at the University of Michigan in Ann Arbor. Aciego and Cambiar started a travel company called Big Chill Adventures and issued a press release that resulted in a New York Times story. During the firm’s first trips in 2015, Aciego enjoyed sharing awe-inspiring spectacles, such as the Greenland ice sheet, with travellers. Aciego left her job in Michigan, and now splits her time between Big Chill Adventures and working as a flight instructor and as a part-time adjunct assistant professor for the University of Wyoming in Laramie.
