Claire L. Parkinson, Ph.D.

Dr. Claire L. Parkinson is a climatologist world-renowned for her work on sea ice, satellite observations, and climate change. She was drawn to polar research because of the Antarctic Treaty, which preserves an entire continent "for peaceful purposes only," and became one of the earliest women to conduct fieldwork in Antarctica when, as a graduate student, she participated in an otherwise all-male Ohio State University expedition in 1973 to 1974. For her dissertation, she developed the first computer model of Arctic and Antarctic sea ice incorporating both sea ice dynamics and thermodynamics before joining NASA and becoming an early expert in analyzing satellite data.

Claire Lucille Parkinson was born on March 21, 1948, on Long Island, New York, and moved to Montpelier, Vermont, in 1960. She earned her B.A. in Mathematics at Wellesley College in 1970, then tutored delinquent teenagers in Burlington, Vermont, before entering graduate school at Ohio State, where she earned her Ph.D. in Geography/Climatology in 1977.

Parkinson moved to Greenbelt, Maryland, in 1978 and has lived in Greenbelt for over 41 years, working as a climate scientist at NASA's Goddard Space Flight Center. Her career at NASA began in a small group tackling the problem of determining sea ice information from satellite data. The group published the first atlas of Antarctic sea ice from satellite data in 1983, after which Parkinson assumed leadership in producing the corresponding atlas for Arctic sea ice, published in 1987. Since then, she used satellite data to determine and quantify changes in the sea ice covers of both the Arctic and the Antarctic (1970s). Parkinson authored a 1985 book on the history of science, a 1997 book on examining the Earth with satellite imagery, and a 2010 book, Coming Climate Crisis? Consider the Past, Beware the Big Fix, summarizing 4.6 billion years of climate change and detailing her concerns regarding potentially dangerous geoengineering proposals. She also co-authored several books, including a textbook on climate modeling.

Starting in May 1993, Parkinson additionally served as Project Scientist for the Earth-observing Aqua satellite, launched in May 2002, that transmits data regarding Earth's atmosphere, oceans, land, and ice. Scientists worldwide continue to use the Aqua data in thousands of publications and numerous practical applications, including weather forecasting and forest fire monitoring.

Throughout her career, Parkinson engaged in outreach to children and the public, and since childhood, was involved in issues of civil rights. She was an invited speaker at a Martin Luther King Day commemoration in Vermont in 2007 and volunteered full-time for 38 days in the recovery efforts following a sequence of devastating hurricanes in 2017. Her NASA outreach includes leading a collaboration between NASA and the Maryland Women's Heritage Center that produced a book and six posters on Women of Goddard: Careers in Science, Technology, Engineering, and Mathematics.

Parkinson became a member of the prestigious U.S. National Academy of Sciences, National Academy of Engineering, American Philosophical Society, and American Academy of Arts and Sciences. In 2020, Parkinson received the Roger Revell Medal for her “outstanding contributions in atmospheric sciences, atmosphere-ocean coupling, atmosphere-land coupling, biogeochemical cycles, climate or related aspects of the Earth system.”
