Dr. Jennifer Francis’ interest in Arctic weather and climate was sparked by a summer spent sailing near Svalbard in her 20s. Throughout her career, she has pioneered the use of satellite data to understand the dramatic changes taking place in the Arctic, and how disproportionate warming there is affecting temperate regions on Earth—where billions of people live. Her groundbreaking work suggests that rapid Arctic warming may be linked to shifting weather patterns in North America and Eurasia, driving more persistent weather regimes that can generate periods of extreme temperature and/or precipitation.
