Description
Follow Dr. Kenny Broad as he dives into blue holes, the underwater caves that formed during the last ice age when sea level was nearly 400 feet below what it is today. With an interdisciplinary team of climatologists, paleontologists, and anthropologists, Broad investigates the hidden history of Earth's climate as revealed by finds in this spectacularly beautiful 'alternate universe.'
