One of the leading and most cited scientists dealing with Earth’s “cryosphere” (frozen regions), Dr. Julienne C. Stroeve discusses diminishing snow and ice cover, and the emerging impacts for animals, ecosystems, and coastal cities all around the world.
In this podcast episode, Dr. Stroeve discusses her recent multi-month voyage on the MOSAIC Expedition inside the Arctic Circle, where a Polar Bear watch was maintained while setting up specialized data-gathering equipment. As snow and ice cover diminishes around the planet, its reflective nature (“albedo”) is lost, and more solar energy is absorbed into landscapes and ocean water in the form of heat. Melting ice and glaciers in Greenland alone have the potential to raise sea level 7-8 meters (23-26 feet), and the terrestrial ice of Antarctica has an 80 meter sea level rise potential – 260 feet! Dr. Stroeve discusses how it is the poorest and in many cases indigenous communities world-wide who are most vulnerable to the severe impacts of our changing climate – and that climate change is therefore a social justice issue. But, despite all of the trending data, she remains hopeful and optimistic that the global community is waking up, responding, and deploying innovative strategies to help stabilize our the planet’s climate.
Dr. Stroeve received a PhD in geography from the University of Colorado – Boulder in 1996 for her work in understanding Greenland climate variability. Afterwards she became a senior research scientist at the National Snow and Ice Data Center (NSIDC) within the Cooperative Institute for Research in Environmental Sciences (CIRES) at CU-Boulder, where multiple briefings for the CIA Task Force on Climate Change were held. More recently she was a Professor at University College London and recently was awarded a Canada Excellence Research Chair at the University of Manitoba.
Her Arctic research interests are wide-ranging, and include sea ice forecasting at seasonal, decadal and longer term time-scales, climate change and impacts on native communities. She has participated in several field campaigns in Greenland and the Arctic Ocean. Efforts over the past decade have increasingly focused on trying to make sense of the rapid environmental changes being observed in the Arctic and what these changes will mean for the rest of the planet.
Dr. Stroeve’s work has been featured in numerous magazines and news reports, radio talk shows, and TV documentaries. She has given keynote addresses around the world on Arctic climate issues and briefed former Vice President Al Gore and Congressional Staff of Republican, Democratic, and Independent members of the United States Congress. Dr. Stroeve has published more than 80 articles in peer-reviewed journals and has contributed to several national and international reports on climate change. Stroeve has been named by Clarivate Analytics as one of the most highly cited researchers 5 years in a row.
