Looking at Figures 24-1 and 24-2, does the recent increase in global temperature exhibit such a lag?
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).
Research suggests that over the last few hundreds of thousands of years, changes in atmospheric CO2 concentration sometimes lagged behind a temperature increase by perhaps 1000 years—indicating that “feedback” loops associated with a warmer climate might lead to increasing CO2 in the atmosphere rather than the other way around.
What will be an ideal response?
No
