Natural Disasters [Naturkatastrophen] by Claire Watts

LEARNING FROM THE PAST
Geologist drill samples called cores       from the ancient ice deep inside the   Antarctic ice sheet. The ice cores reveal information about surface temperature over thousands of years, as the ice sheet developed. Ice cores can also show how much carbon dioxide, volcanic ash, dust,  and pollen used to exist in the atmosphere. Studying how climate and atmosphere have changed in the past  may help scientists predict how it will change in the future.
