What Penguin Bones Can Tell Us About Dying Glaciers

The video discusses the rapid warming of polar regions, focusing on Antarctica's glaciers, particularly the Thwaites and Pine Island glaciers. It explores the potential for these glaciers to collapse, raising global sea levels significantly. The video examines whether these glaciers have historically rebounded after melting, using carbon dating of penguin bones and seashells to study past sea levels. Findings suggest that the glaciers have been stable for thousands of years, with no evidence of past rebounds. This highlights the urgency of addressing climate change, as current glacier melting is unprecedented.
