CO2-temperature trends from the Vostok ice core, of the previous glacial-interglacial transition ~120,000 years ago according to Petit, Fisher and many more
Remarkable is that the temperature in the first few thousands of years was some 3 ºC warmer than today. That is not only visoble in the ice core record of Antarctica, but also in pollen found in Alaska, which points to forests growing much farther North, where tundra is today.
Also remarkable is the fact that the temperature is already near it's minimum before CO2 starts to reduce at the start of the new ice age.
