Ice cores drilled from the Antarctic ice sheet provide scientists with a remarkable record of Earth's past climate. As snow falls and is gradually compressed into ice, tiny bubbles of air (1) ---- inside it. By analysing these bubbles, researchers can determine the composition of the atmosphere at the time the snow fell. The deepest cores obtained so far contain ice that is around 800,000 years old, (2) ---- them an invaluable source of information about long-term climate cycles. The data clearly show that carbon dioxide levels and temperatures rose and fell together (3) ---- this period. (4) ----, present-day carbon dioxide concentrations are far higher than at any point recorded in the ice. Scientists are now searching for even older ice, which they hope will help them understand why the pattern of ice ages changed about a million years ago, a question that (5) ---- unanswered for decades.
