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.

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.....

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  

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

See attached.. PhD position on reconstruction of the global biosphere productivity during the last deglaciation Project Description The concentration of atmospheric carbon dioxide (CO2) changed more than 100 ppm over transitions between glacial and interglacial periods (deglaciations) during Quaternary. Among others, the role of global biosphere (terrestrial and marine realms) on the deglacial CO2 changes remains uncertain.

Background For the Paris agreement on Climate, timely reporting of greenhouse gas emissions by nations for different sectors and gases is needed.

Conférence "Les glaces polaires, archives des climats anciens" par Marc Delmotte Le cycle de l'eau est un mécanisme essentiel du climat. Depuis des centaines de milliers d'année, la neige s'accumule au Groenland et en Antarctique, formant ainsi des grosses calottes de glace qui renferment de précieux témoignages des climats passés.

    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.
