I work at the Laboratory of Glaciology and Environmental Geophysics on the reconstruction of past climates and climate focusing using physico-chemical markers ‘archived’ in sediments, mainly ice. These markers are natural isotopes, whose chemical behavior, or isotopic fractionation due to their mass difference, is sensitive to climatic conditions (‘isotopic thermometer’), or to solar forcing (production of cosmogenic isotopes). Now part of the Institute of Environmental Geosciences.

Biomass, a massively available and major source of energy, an unsustainable use

For thousands of years, the use of biomass has been sufficient to meet people’s vital needs, providing food, heat, fibers (e.g. clothes) and even shelter. Industrialisation was initially based on wood energy, mostly charcoal: however, the damage to forests was so important, both in China and in Western Europe, that its use was restricted. The…
