We are proud to share with you the announcement of the election of Robert Vautard, former director of LSCE and current director of IPSL, as co-chair of Group I of the IPCC. We wish him the best within his new role. Official link to the IPSL annoucement: https://www.ipsl.fr/article/robert-vautard-de-lipsl-a-lipcc/

The mid-latitudes of the Southern Hemisphere are characterized by strong westerly winds circulating in a relatively narrow band of latitudes. These zonal winds play an important role in ocean circulation and influence the oceans' capacity to store carbon. These winds are therefore also thought to play a key role in regulating atmospheric CO2 during past glacial-interglacial cycles. However, past variations in their position and strength remain poorly understood.

A Franco-German study coordinated by the LSCE (CEA-CNRS-UVSQ) estimates that climate change could shift the peak in Arctic Ocean acidity from winter to summer, which would be disruptive to the ecosystem.. See

    A “double-edged sword” - the reduction of soil available phosphorus by increases in atmospheric CO2       c)okugawa/Getty Images   Carbon dioxide (CO2) uptake by photosynthesis allows crops to grow biomass. Crops are expected to produce more biomass with a higher CO2 concentration. This is the CO2 fertilization effect widely known in the scientific community.

See: attached We are seeking seven (7) enthusiastic and highly motivated candidates to work on new representation of carbon loss pathways, leveraging novel observations, theoretical understanding, machine learning tools and integration of processes with land surface models. The topics range from modelling microbial carbon use efficiency, extreme fires, permafrost collapse, and nutrient constraints on tree-based carbon dioxide removal, and near-real time model predictions.....
