5. Are we currently in a glacial or interglacial period? Approximately, when did this most recent period of climate begin?
6. Calculate the estimated rate of change for three sequential glacial-interglacial periods. To do this, zoom in on the time series graph to the glacial-interglacial periods listed in the table below. In the table you are given a one thousand year range to examine. You will look at all points in that thousand year period by running your cursor over the points. You will note the temperature anomaly for each point and then estimate the average for that range. Complete the table below by answering the following:
What is the range of years for each glacial-interglacial period listed?
What is the temperature anomaly estimate for this glacial period?
What is the temperature anomaly estimate for this interglacial period?
Subtract your glacial period estimate from your interglacial period estimate and divide by the range.
