Question

This data set was created from examining several ice cores drilled at Antarctica's Vostok Station in 2001. Examine the data and write about one correlation that you see. What does the correlation tell you about Earth’s historic atmosphere or climate? (ybp = years before present, ppb = parts per billion, and ppm = parts per million)
