Climate and environmental


Saclay researchers are committed to trying to understand the behaviour of climate to predict the changes brought about by human activities.

The models developed to predict situations not previously encountered in the history of the planet are tested on past climate models very different from that of the present day, such as the ice ages. They can be reconstructed by using isotopic analysis of the ice caps or of marine sediments. Studying recent fluctuations in climate helps in clarifying the mechanisms involved. The part played in the environmental cycle of greenhouse effect compounds (carbon dioxide, aerosols, etc.) are also carefully studied. Finally the isotopic tool is used to date past events and study transfer of matter in today’s environment.
