Were there times over the last 800,000 years when temperature in the Antarctic was lower than today? If so, how much colder?
The question is based on Figure 24-5, showing variations in CO2 and temperature anomalies in Antarctica going back 800,000 years. This temperature record shows the major glacial (cold) and interglacial (warm) periods of the later Pleistocene Epoch (2.58 million to 11,700 years ago).
What will be an ideal response?
Yes; several times it was as much as 14°C colder than today.
