Abstract Computational quantum physics has recently seen a dramatic increase in its capabilities, precision, and predictive power. The advances have been driven by method and code development, benchmark, and collaboration. Together with exciting recent …

Abstract The question of how heritable mutations arise is one of long-standing interest in biology. In the case of bacteria, there was a debate about whether mutations arise as a consequence of adaptation to selective pressure from the environment, or …

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 …
