The reliable paleoclimate record from the Antarctic and Greenland ice cores provides information back to approximately 700,000 years ago. This is because the ice layers in these cores provide a continuous record of past climate conditions, including information on temperature, atmospheric composition, and atmospheric circulation. By studying isotopes of various elements in the ice layers, scientists can also gain insights into past changes in ocean circulation and other aspects of the climate system.
