The graph shows the close relationship between the rise and fall of CO2 and the rise and fall of global temperatures as recorded in ice cores and, since 1958 by direct measurements at the Mauna Loa Observatory. Except for the Eemian Interglacial (which was specifically mentioned in your OER Chapter 6 readings), all interglacial peaks are numbered P1-P5. What is the average interval between the five highest interglacial peaks (high temperature, high CO2) during this 425,000-year portion of the record? Group of answer choices 425-450,000 years 100-105,000 years 150-160,000 years 25-30,000 years
