Abstract Based on decades of scientific development in a highly collaborative environment, numerical climate models are essential tools for understanding and anticipating climate impacts and risks. Initially developed in a research context for large-scale …

Abstract Although climate should not be reduced to temperature, it is the simplest parameter to describe and quantify. Global warming over the last two  hundred years, and particularly since 1970, is undeniable, but some see it as the result of urban …

Abstract Humans and other animals have minds because reality is predictable. The world is full of items that behave in regular ways. Our minds lock onto these items so that we can anticipate events and act accordingly. The central role of thoughts is thus …

Abstract After describing the integration procedure on quotient spaces, we derive Mirzakhani's first integration formula, which expresses the integral of functions of the type " length of a multi-curve " in terms of the volume of the moduli space of the …

Abstract The earliest funerary statuettes were included in the funeral trousseaux of the First Intermediate Period and the Middle Kingdom in the form of single specimens. During the New Kingdom, the number of statuettes per deceased grew considerably, …

Abstract Theoretical and observational advances in modern astrophysics and cosmology tell us that the Universe today is made up of a very small fraction (~5%) of ordinary matter, the rest being made up of constituents whose nature is still unknown: dark …

Abstract In the Local Group, the best estimate of mass is given by the Viriel theorem. Compact groups pose the problem of their lifetime. In fact, according to simulations, they have not been compact for a long time. In galaxy clusters, there are several …

Abstract In modeling, evolutionary phenomena are often analyzed through the prism of partial differential equations, interpreted as a macroscopic description of the problem of interest. However, this classic approach comes up against the problem of model …

Abstract This question is crucial to a full understanding of the evolution of the Solar System. We will examine various constraints, such as the evolution of the bombardment of telluric planets, recorded by lunar craters, the survival of binary objects in …

Abstract Atmospheric water vapour is the first   greenhouse gas and plays a major role in our climate and its changes. Indeed, because of the link between temperature and the capacity of air to contain water vapor, this gas amplifies by a factor of 2 to 3 …
