See english below ********* Après une semaine intense d'approbation avec les représentants des gouvernements, le rapport de synthèse va sortir aujourd'hui à 14h. Il clôture le sixième cycle du GIEC avec une synthèse des messages clés des six rapports : voir https://www.ipcc.ch/report/ar6/syr/ Un comminiqué de presse est disponible à https://www.ipcc.

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.

An international collaboration involving the LSCE (CEA-CNRS-UVSQ) recommends the earliest possible deployment of these technologies on a large scale. If postponed to the latter half of this century, the available biomass production would be largely reduced by climate change, jeopardizing the goal of containing global warming to 2°C by 2100, and potentially leading to food shortages. https://www.cea.

Dear colleagues,   A reminder that we welcome applications for a PhD candidate to work on the impact of gateway changes on the ocean circulation and carbon cycle in the Late Eocene using the IPSL earth system model and PISCES biogeochemical model starting next fall for 3 years (see attached). The work will be carried out at the Laboratoire des Sciences du Climat et de l'Environnement (LSCE, https://www.lsce.ipsl.fr/en/index.php) near Paris, France.

We are looking for a motivated candidate for a 6 months project in data science to analyze the large datasets of forest sites from the national forest inventory in France for recent changes
