Elephant seal remains show Antarctic sea was warmer in the mid-to-late Holocene

Studying the response of Antarctic ice sheets to past warming episodes is essential to understand how they may respond to the present warming climate, as their melting and collapse can contribute to global sea level rise. Detailed records of past ocean temperatures close to the continent are rare, but clues to how ice sheets and sea ice responded to global conditions in the past can be found in funny places—even in the remains of animals that once lived there.
