KIT Climate Lecture:

Past climates trapped in the ice

Water isotopes : atmospheric modeling and applications to polar ice core studies

Professor Jean Jouzel, Research Director, Atomic Energy and Alternative Energies Commission (CEA), France

 

Abstract

The presentation will first address theoretical aspects related to the physics and

the modeling of water isotopes in the atmosphere. Then a few examples shall

illustrate the climatic information that can be extracted from these isotopes

measured along deep ice cores drilled in Greenland and Antarctica. Recent

advances are based on progress in methodologies thanks to technologies which

have revolutionized this field of research, i.e. better measurement techniques of

the 17O/18O ratio, as well as enhanced technologies for simulation and analysis.

This allows to extend the climatic information over 8 glacial-interglacial cycles in

Antarctica and back to the Last Interglacial in Greenland.

 

Jean Jouzel is Research Director at the Atomic Energy and Alternative Energies

Commission (CEA). His main scientific involvement has been with the use of water

stable isotopes (deuterium and oxygen 18) for reconstructing past climate changes

from ice cores at various timescales, and with associated atmospheric modelling.

He has participated in major international ice core projects in Antarctica and

Greenland. Currently, he is Vice-Chair of the IPCC Working Group I.
