Summary

Discover the studies behind the statistics of 6th IPCC report and the research work of scientists who aim to gain a better understanding of climate change and its impact.
This first episode presents the work carried out by members of the LSCE (Laboratoire des sciences du climat et de l'environnement) at the Traînou site in France. These scientists collect air samples using stratospheric balloons that reach altitudes of over 30 km. The analysis results of these samples are then used to obtain a precise measurement of the concentration of greenhouse gases (CO2).
This data is used for climate modelling and, together with satellite data and data collected by the ICOS network stations, can be used to map carbon dioxide concentrations on a large scale.

CNRS Images,

Our work is guided by the way scientists question the world around them and we translate their research into images to help people to understand the world better and to awaken their curiosity and wonderment.
