Abstract After a brief introduction to the CGDD, the research sub-department and their involvement in geoengineering, this talk will present current French positions on the two main families of techniques, carbon removal (EDC) and solar radiation …

Abstract Marine geoengineering (the specific subject of this talk) is one of the scientific techniques that could ultimately help combat global warming. As such, it is the subject of this symposium. However, it also presents a serious and irreversible …

Abstract CO 2 is a molecule that has already been used on a large scale for decades for a variety of applications: chemistry, agri-food, plant growth, extinguishing agent, water treatment... The geological storage of CO 2 has also been implemented for …

Abstract Achieving carbon neutrality (Net Zero) by 2050 requires, in addition to massive emissions reductions, the development of tools to actively remove CO 2 from the atmosphere. So-called "negative emissions" technologies have become an indispensable …

Abstract Most scenarios developed to limit global warming involve negative emissions, i.e. the sequestration of carbon dioxide from the atmosphere. In this context, ecosystems, which currently absorb almost a quarter of our emissions, represent one of the …

Abstract A commonly discussed form of geoengineering is the modification of solar radiation. A number of technologies could be used to reduce solar radiation incident on the Earth in order, in theory, to counteract global warming. In 2024, the European …

Abstract This presentation explores geoengineering – a set of ideas aimed at cooling the planet if cutting greenhouse gas emissions isn’t enough to stop climate change. It looks at two main strategies: Solar Radiation Management (SRM) and Carbon Dioxide …

Abstract François-Marie Bréon will introduce the conference by recalling the context of ongoing climate change and the need to limit warming to less than 2 degrees. He will describe the concept of geo-engineering, distinguishing between techniques aimed …

Panagiota Sarischouli is invited by Prof. Jean-Luc Fournet, Chair of Written Culture in Late Antiquity and Byzantine Papyrology . Abstract Although the phenomenon of voces magicae is most often associated with Roman and Late Antique Egypt, the use of …

Abstract It has long been recognized that sign language (i) uses the same logical structures as oral language (sometimes bringing out its abstract components), and at the same time (ii) makes more systematic use of iconicity. But the articulation between …

Abstract Syntactic structures are complex objects. Obviously, there is no upper limit to the length of a sentence (we can't identify "   the longest sentence in French   "), but it's not simply a question of linear length (number of words). It's also, and …

Résumé La conférence portera sur le milieu d'origine de Julius Oppert, ses modèles convertis ou non et son arrivée en France ou comment un professeur d'allemand de province devient le fondateur d'une nouvelle discipline. Elle tentera de montrer les enjeux …

Abstract AI progress is accelerating, and now the leaders expect "artificial general intelligence" (AGI) in 2 to 3 years. While difficult to believe, we must prepare for the possibility. We can take some lessons from previous episodes in which computers …

Abstract A sober, reasoned list of what we need to make the most of Ebla texts, including new working tools (traditional and digital) and young researchers capable of a holistic approach. The question of full publication and open access. Minimum …
