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.

Bonjour, Un poste CNRS FSEP de "Technicien-ne en instrumentation, expérimentation et mesure" est ouvert au CEREEP-Ecotron IDF, à Saint-Pierre-lès-Nemours (77). Notre unité est une structure d’accueil et d’accompagnement de la recherche expérimentale en écologie.

.. ​For the first time ever, an international collaboration involving the LSCE (CEA-CNRS-UVSQ) is providing a global view of large CO2 plumes attributable to fossil fuels through satellite observations.
