30 Years of Changes in Ice and Polar Bears (George Durner)

Over the past 30 years, the Arctic has undergone significant changes, especially in the region where polar bears are studied, the Southern Beaufort Sea. The loss of sea ice has increased in duration and extent, causing polar bears to be displaced from their optimal habitat on the continental shelf to deep waters of the Polar Basin during summer months. As a result of finding less to eat in these deeper waters, polar bears experience reduced body condition, muscle mass loss, decreased activity, and challenges in reproducing and raising cubs. Dr. George Durner, a research zoologist, highlights the complexity of these changes and acknowledges the substantial amount of research conducted by his team and collaborators to understand the impacts on polar bear populations.
