In the second part of Angela Wheeler's interview with geologist Koen Vogel, Ph.D., they discuss what may have caused the massive ice sheets of the last Ice Age to melt.

Drawing on peer-reviewed research, Dr. Vogel examines the evidence behind CO₂, Milankovitch cycles, and other proposed explanations, highlighting why many popular theories struggle to explain the timing and scale of the deglaciation.

The discussion explores abrupt climate shifts, ancient ice sheets, and the scientific challenges of reconstructing Earth's climatic past.
