How has the climate changed in the course of the Earth’s history? Which climatic processes have influenced the Earth and its atmosphere? Paleoclimatology seeks answers to such questions in order to better understand climate changes and to derive forecasts for future climate scenarios. So-called sedimentary archives serve as a basis for this. They are rock deposits whose components and composition provide information about the temperatures and climatic conditions at the time of their formation. Correspondingly recent geological deposits provide information about the climate development in the recent history of the Earth since the last ice age 20,000 years ago. Compared to widespread seawater deposits, however, sedimentary archives on the mainland—such as in the Alpine region—are very rare.
