store CO2 so that temperatures fall back below 1.5°C, a need that worries scientists – Libération

How to address it is a divisive debate, but it is no longer possible to avoid it: wherever we talk about climate,surpass has now become an important subject. This concept has never been as driving a discussion at a UN summit as it was at COP30, held November 10 to 21 in the city of Belém, at the gateway to the Brazilian Amazon. In the context of increasing global average temperatures, overshoot refers to the trajectory that will cause the world to pass the 1.5°C warming threshold before returning below that threshold by removing CO₂ in the atmosphere through industrial processes, which until now have been carried out mostly by more or less serious start-ups. Whether it’s directly capturing CO₂ in the atmosphere using machines and chemical formulas, fertilizing the oceans to stimulate the growth of photosynthetic microorganisms necessary for proper carbon sequestration, or even amplifying rock changes, these geotechniques
