The goal of this course is to present an overview of the methods used to reconstruct the Earth?s climate history and the techniques used to determine the timing of environmental changes. A special focus will be placed on environmental magnetism an attractive modern method based on magnetic properties of minerals.

The importance of paleoclimatic studies for understanding the future development of the Planet

Global Climate Models, feedback loops and uncertainties, scenario base climate predictions, persistence of warmer Earth, human dimension of climate change, effects on various systems and environments.

Methods and environments suitable for paleoclimatic and paleoenvironmental reconstructions

Sources of paleoclimatic information, levels of analysis, modeling of paleoclimate, stable isotope analysis of ice cores and calcareous marine fauna, relative abundance studies, coral record studies, loess and paleosol, periglacial features, mountain glacier fluctuations, lake sediments, cave sediments, non marine biological evidence, pollen analysis.

Dating Methods

Radiocarbon dating, Potassium-argon dating, Uranium series dating, Luminiscence dating, fussion track dating, aminoacid dating, obsidian hydration dating, tephrochronology, lichenometry, dendrochronology, paleomagnetism.

Character of past climatic of the ice age world, how it was maintained and how it is studied

Extent of the ice sheets and the glacioeustatic sea level record, isotopic constraints of glacial temperature and ice volumes, oxygen isotope analysis, accurate estimation of sea surface temperatures, continental and low latitude paleoclimates, dust sources and deposition during the last glacial maximum, natural paleoclimatic archives.

Nature of the climate cycles and its origin

Atmospheric forcing of climate change during the Glacial Maximum, radiative forcing of climate by ice-age atmospheric dust, precession and eccentricity influence in the climate cycle, insolation cycles as a major control of oceanic production, characteristics and causes of the 100 kyr cycle, structure and origin of major glaciation cycles, orbital forcing of climate, mechanisms of climate response and implications for thermohaline circulation, variation in the Earth magnetic field and its influence on climate.

Rapid climate change events, their dynamics and how they are studied

Links between the monsoon and rapid climate change, connection between rapid climate change and the ocean conveyor circulation, changes in deep-water formation and the Dansgaard-Oeschger temperature oscillations, modeling of the relation between the conveyor circulation and rapid climate change, thermodynamic model for the bipolar seesaw, simulations of rapid changes of glacial climate in a coupled climate model, equatorial origin of rapid climate change events
