If all has gone according to plan, 38-year-old Susana Hancock should be more than halfway through a 600-mile trek in one of the planet’s most remote and hostile environments to document the rapid retreat of the Greenland ice sheet. The small, one-pound sensors she is installing as she skis across the world’s second-largest polar ice cap will measure greenhouse gas emissions and ice thickness. That data is critical for global climate monitoring in a region that is “very poorly monitored in real time,” Hancock said during an interview last month before leaving for Tasiilaq, an island in East Greenland, where she was set to begin her trip a week later.
