Summary:
Can Antarctica's climate past offer clues to what may happen to our warming planet? To gather crucial evidence, NOVA follows an ambitious Antarctic investigation -- a state-of-the-art drill┬Čing probe known as ANDRILL. Drilling deep beneath the Antarctic ice, down through the sea and three-fourths of a mile into the seafloor, ANDRILL recovers rock cores that reveal intimate details of climate and fauna from a time in the distant past when the Earth was just a few degrees warmer than it is today. As researchers grapple with the harshest conditions on the planet, they discover astonishing new clues -- not only about Antarctica's past, but also Earth's future.
