Charles Cockell – författare

Much has been written about the effects of increased UV radiation caused by stratospheric ozone depletion on the weather, but there has been a dearth of publications on the role of UV on ecosystems as a whole. Now that much more is known about the effects of UV radiation at the organism level, we are gaining an understanding of how this impacts on specific ecosystems. From microbial to plant ecosystems, the book examines how changes in UV radiation, caused by anthropogenic ozone depletion, as well as changes in radiation levels throughout the evolution of life on Earth, can alter species composition and interspecies competitiveness. Two foci of the book are the evolutionary aspects of the effects of UV and also the various synergistic interactions of UV radiation with other environmental factors. Because our knowledge of UV effects on whole ecosystems is still at a relatively early stage, an important part of each chapter is an overview of future research directions and indications of where new data and knowledge are needed.

This concise undergraduate textbook brings together Earth and biological sciences to explore the co-evolution of the Earth and life over geological time. Written for a one-semester course, it explores the Earth system at and above the surface of the Earth by examining the interactions and feedback processes between the geosphere, atmosphere, hydrosphere and biosphere. It also explains how the Earth's surface environment involves a complex interplay between these systems. Through a wealth of features and student questioning, the book allows students to understand how physical controls make our planet hospitable for life, investigate the processes of global change that operate on a range of timescales, understand important cross-disciplinary connections and explore how the whole Earth system has evolved. Finally, it assesses how and why the climate of the Earth has varied over geological time, and considers whether life itself is passive or an active agent for change.

A captivating journey through nature, this book explains why life is like it is

Britain's foremost astrobiologist offers an accessible and game-changing account of why life is like it is.The puzzles of life astound and confuse us like no other mystery. But in this revolutionary new book, Charles Cockell reveals how nature is far more understandable and predictable than we think. Refining Darwin's theory of natural selection, Cockell puts forward a remarkable and elegant account of why evolution has taken the paths it has. From animals to atoms, he shows that is it not biology, but physics, which is the true touchstone for understanding life in all its extraordinary forms._______________An intriguing and enthralling adventure into the physics of life that is all around us and inside us. Cockell provides a reminder of the seeming rarity of all this beauty but also an invitation to look up to the skies and ask 'where else might something like this be?' - Robin Ince - Presenter of BBC Radio 4's Infinite Monkey CageRiveting... Cockell is not only a fine scientist but a fine writer too. - Sir Martin Rees - Astronomer Royal and former President of the Royal Society

This volume provides an in-depth discussion on the central question – how can people express and survive dissent and disagreement in confined habitats in space? The discussion is an important one because it could be that the systems of inter-dependence required to survive in space are so strong that dissent becomes impossible. John Locke originally said that people have a right to use revolution to overthrow a despotic regime. But if revolution causes violence and damage that causes depressurisation with the risk of killing many people, is it even permissible to have a revolution? How then are people to express their liberty or dissatisfaction with their rulers? The emergence of structures of dissent and disagreement is an essential part of the construction of a framework of liberty in space (revolution is just the extreme example) and thus the topic deserves in-depth and immediate attention. Even today, the way in which we assemble organisations and corporations for the government and private exploration of space must take into account the need for mechanisms to allow people to express dissent.

The biological effects of asteroid and comet impacts have been widely viewed as primarily destructive. The role of an impactor in the K/T boundary extinctions has had a particularly important influence on thinking concerning the role of impacts in ecological and biological changes. th During the 10 and final workshop of the ESF IMPACT program during March 2003, we sought to investigate the wider aspects of the involvement of impact events in biological processes, including the beneficial role of these events from the prebiotic through to the ecosystem level. The ESF IMPACT programme (1998-2003) was an interdisciplinary effort that is aimed at understanding impact processes and their effects on the Earth environment, including environmental, geological and biological changes. The IMPACT programme has 15 member states and the activities of the programme range from workshops to short courses on topics such as impact stratigraphy, shock metamorphism, etc. The program has also awarded mobility grants and been involved in the development of teaching aids and numerous publications, including this one.
