Une synthèse sur les enjeux, les causes et les conséquences du changement climatique, fondée sur un état des lieux des connaissances scientifiques sur le sujet. L'auteur explique notamment les liens entre climat et météorologie, le rôle du Soleil dans le réchauffement ou encore l'importance des recherches géologiques pour comprendre les phénomènes climatiques.

Middle East and Mediterranean region locates at a crossroad of global climatic patterns. The region is under the influence of a convergence of different maritime conditions which together with extensive adjacent land masses marked by extreme differences in topographical features transporting continental air masses lead to a diverse climate. This edited volume is based on the best papers accepted for presentation during the 1st Springer Conference of the Arabian Journal of Geosciences (CAJG-1), Tunisia 2018. It gives new insights on patterns and mechanisms of past, present and future climate/environmental changes mainly on Middle East and Mediterranean region by international researchers. The book is of interest to all researchers in the fields of climate, paleo-climate and paleo-environmental studies. Main topics include: • Spatio-temporal Patterns of Climate Change • Sea Level Variability • Climate Change Impacts and Migration Schemes • Paleoclimate Evolution • Paleoenvironmental Evolution.

This book gathers invited contributions from active researchers to provide an up-to-date overview of the geological setting of the Red Sea. It discusses aspects ranging from historical information to modern research in the Red Sea, and presents findings from rapidly advancing, emerging fields. This semi-enclosed young ocean basin provides a unique opportunity to study the development of passive continental margins in order to examine the current status of that region. In addition to studies on the Sea itself, it includes those from related fields on the littoral zone. The book is of interest to geoscientists and non-specialists alike.

The cryosphere is very sensitive to climate change, and glaciers represent one of the most important archives of atmospheric composition and its variability. From the Himalaya to the European Alps, the longest mid-latitude mountain chain in the world, lie thousands of glaciers that have collected atmospheric compounds over the last millennia. China and Italy are located at the opposite terminals of this long mountain chain, comprising strategic positions for understanding climate evolution and providing important information for the modeling of future climates. The results presented are highlights of some of the most recent advances in cryospheric studies, especially on the topic of mineral dust and aerosols in the atmosphere. They evidence the complexity of the chemical–physical processes involving solid compounds occurring in glacier, snow, and permafrost environments, covering different aspects such as spatial and temporal trends, as well as the impact of mineral and nonmineral particles. Results also show that recent advances in measurement techniques and source apportionment may be powerful and sophisticated tools to provide novel, high-quality scientific information.
