Abstract

The generalized isotopic paleotemperature curve reproduces absolute temperatures to within 1°C; it closely reflects faunal changes; and its time scale is correct to within a very few percent back to at least 175,000 years. The average oxygen isotopic composition of the North American and European ice caps was about -9 per mil.
