Why is it important to compare records from different locations? What other locations would you examine to study climate?
Examine Figure 18.2. The Vostok ice core is 3310 m (10,860 ft) long. The full record extends back to 422,000 years before the present. The figure shows CO2 in parts per million (ppm) and temperature anomalies in Celsius degrees.
What will be an ideal response?
It is important to determine if climatic changes are local, regional, or global. I would also want to examine other high latitude locations, along with mid-latitude and tropical locations.
