The Anatomy of Glacial Ice Loss

11.05.2020
Combined, Greenland and Antarctica contain enough ice, that if it were to melt all at once, would raise sea levels by nearly 215 feet (65 meters) – making the study and understanding of them not just interesting, but crucial to our near term adaptability and our long term survival in a changing world.
