Good evening.
I have a question about global warming that I was hoping folks could help me with.
I see from the Vostok ice core data graph 2, posted in a link below, that over the last 18,000 years CO2 ppm has gradually increased from about 180 ppm to a little less than 300 ppm.
However during this period of gradual CO2 ppm increase, we see average temperatures often increase dramatically (+2.5C) then decrease dramatically, even though there is no sudden change in CO2 ppm (according to the graph).
My question is: do the Vostok ice cores also show periods of rapid and sudden CO2 ppm increase with no corresponding increase in temperature?

Thanks for your help.
