Paleotemperature Changes in the Upper and Middle Pleistocene

Abstract. By the combination of land and sea data the author came to the conclusion that the duration of the Middle and Upper Pleistocene glacial ages was of the same order of magnitude. The temperature of the glacial ages was not exactly the same, but each younger glacial age was a little colder than the preceding one. Similarly, each younger interglacial age was a little cooler than the preceding one. Bringing together all known data the complex Pleistocene generalized paleotemperature curve is constructed showing the main trend of the temperature evolution from Mindel glacial until now, spanning the time of about 400,000 years.
