The next Jhe OSU Pyth\u00e9as Scientific Day<\/em>, dedicated to\u00ab\u00a0carbon in all its forms<\/em>\u00a0\u00bbwill take place on Friday 28 November 2025 <\/strong>on the\u2019\u00celot Bernard-Dubois<\/strong>, near Gare Saint-Charles in Marseille.<\/p>\r\n

Among the elements that make up our universe, carbon occupies a unique and essential place. It is at the heart of the chemistry of life, of a complex planetary biogeochemical cycle and of the Earth's climatic equilibrium, in close connection with its major role as a source of energy for human activity.<\/p>\r\n

Recent research confirms its central role in planetary dynamics. The Global Carbon Project (2024) reports that fossil fuel emissions reached a new record of 37.4 Gt CO\u2082 in 2024 (+0.8 % vs 2023), with no peak in sight. At the same time, a study published in Nature Climate Change (M\u00fcller et al.<\/em>, 2025) showed that the oceanic carbon sink weakened by around 10 % in 2023 as a result of record surface temperatures, which reduced the solubility of CO\u2082 and encouraged unexpected degassing. These results highlight the fragility of natural sinks in a context of global warming and the importance of improving our observations and models to anticipate changes in the carbon cycle.<\/p>\r\n

At the\u2019OSU Pyth\u00e9as<\/strong>, Carbon is tracked through observation and research missions, from planetary compartments (soil, vegetation, oceans, atmosphere) to the exploration of extraterrestrial environments (origins and forms of carbon in the Universe). The aim of this work is to gain a better understanding of the mechanisms governing the transformation, transport and storage of carbon on all scales.<\/p>\r\n

Talking about carbon also means tackling major societal issues: climate change, the adaptability of ecosystems and societies, sustainable cities, but also research practices and the carbon footprint of our activities. Carbon science is more than just observing, experimenting and modelling: it raises questions about the sustainability of our societies and leads the scientific community to question its own practices.<\/p>\r\n

Following on from the \u201ccarbon\u201d workshop organised by the OSU's Observation Committee in November 2024, this day is an opportunity to share knowledge, observation results and feedback on carbon \u00abin all its states\u00bb.<\/p>\r\n \r\n
