In the Documentary “Secrets Beneath the Ice In Antarctica”, The scientists studied the climate change by examine the Antarctic Ice Sheet. As the deeper they reached the ice, the further back in time they can study because these ices contained tiny bubbles of ancient atmosphere that trapped each year as the snow was compressed into ice night. In the documentary, they used a machine to drill through ice to gather sample from the nearly two miles thick West Antarctic Ice Sheet.

When they studied the sample like these, they can get a record on how things like temperature and sea ice change in the past. After that, when they
