Dr. Heidi Cullen talks to NASA's Claire Parkinson, who explains the technology used to monitor changes in Arctic sea ice. Long-term tracking shows Arctic sea ice has been on a steady decline, which could have big implications for global temperatures.
Claire Parkinson is a sea ice scientist who has been working at NASA's Goddard Space Flight Center for the past 31 years, studying sea ice from satellite data and linking sea ice to the rest of the climate system. She is also the Project Scientist for the Aqua satellite, which is collecting data about the Earth's atmosphere, oceans, ice, land, and vegetation.
