Studies have demonstrated a link between ozone changes caused by human activities and changing UV levels at the Earth's surface, as well as a link to climate through changes in radiative forcing and links to changes in chemical composition. This book provides contributions on the variable ozone layer and the interplay of longwave and shortwave radiative interactions which link ozone, the climate and UV issues.

Hellenistic Alexandria: Celebrating 24 Centuries presents the proceedings of a conference held at the Acropolis Museum in Athens, on December 13–15, 2017, and includes high-level dialogues and philosophical discussions between international experts on Hellenistic Alexandria. The goal was to celebrate the 24 centuries which have elapsed since its foundation and the beginning of the Library and the Museum of Alexandria. The conference was divided into two parts, to include in the first part archaeology, history, philosophy, literature, art, culture and legal issues and in the second part science, medicine, technology and environment. A total of 28 original and peer-reviewed articles point to the importance of the brilliantly-original ideas that emerged during the Hellenistic age and the curious modernity of the whole atmosphere of the time. The range of presented topics covers a variety of new data on the foundation of Alexandria to comparison between Ptolemaic Alexandria and Ptolemaic Greece through philosophy, culture and drama to the forgotten revolution of science, medicine and the prevailing climatological and geophysical conditions throughout the Hellenistic Period. The conference and its proceedings were co-sponsored by the Μarianna V. Vardinoyannis Foundation, the Acropolis Museum, the Alexandria Center for Hellenistic Studies at Bibliotheca Alexandrina and the Mariolopoulos-Kanaginis Foundation for the Environmental Sciences. The Publication also celebrates the 10th anniversary of the Alexandria Center for Hellenistic Studies, a joint collaboration between the Bibliotheca Alexandrina, the Vardinoyannis Foundation and the University of Alexandria. Scholars from around the world follow the Center’s programme in various specialisations, ranging from historyliterature- art, to archaeology and architecture-philosophy, and science.

Alexandria is located on the Mediterranean coast of Egypt, bordered by Egypt’s Western Desert and the fertile Nile Delta. For many centuries, Alexandria was the major port city in the Eastern Mediterranean and it has been repeatedly struck by natural disasters, such as earthquakes, tsunamis and land subsidence, in its ~2400-year history. This book focuses on the geomorphological and archaeological evidence on the coastal zone of Alexandria, attempting to provide a comprehensive review of its evolution, taking into consideration long-term and short-term factors.The book provides an extensive background on the geomorphology and recent geoarchaeological history of Alexandria, discussing historical maps and natural disasters. In the coastal area of Alexandria there is numerous archaeological evidence, such as burial sites, quarry activities and ancient building remnants, as well as geomorphological features, all revealing a complex evolution of the coastal zone. New evidence, such as fish tanks and ship wrecks in order to discuss the Late Holocene evolution of the coastal zone. Detailed illustrations and maps accompany the book chapters providing the reader the opportunity to gain an extensive view of Alexandria’s features.

Aristotle’s Meteorologica concentrates on the meteorological aspects of Aristotle’s work published as Meteorologica books A-D, and on how they compare now with our understanding of meteorology and climate change. In other words, how well did Aristotle fair when he tried to explain weather 2,300 years ago when there was only logic, eye observation, and past experience, with only primitive instrumentation and a few personalized measurements? While there are scientific issues behind Aristotle’s writings, this book is written for the non-specialist. The book uses simple examples to present its case, which will be easily followed by general readers.

This volume brings together state-of-the-art views on ultraviolet radiation, its modelling, and effects from an interdisciplinary panel of international experts. The growing field of research is presented in a sequence from the arrival of UV light at the top of the atmosphere through its transfer to various biological receptors. Modelling and current issues on UV radiative transfer in clear and turbid environments are discussed. Further, measurements and calibration methods are reviewed and, for the first time, established calibration protocols are presented in a coherent way.
