This book promotes a better understanding of the role of the sun on natural climate variability. It is a comprehensive reference book that appeals to an academic audience at the graduate, post-graduate and PhD level and can be used for lectures in climatology, environmental studies and geography. This work is the collection of lecture notes as well as synthesized analyses of published papers on the described subjects. It comprises 18 chapters and is divided into three parts: Part I discusses general circulation, climate variability, stratosphere-troposphere coupling and various teleconnections. Part II mainly explores the area of different solar influences on climate. It also discusses various oceanic features and describes ocean-atmosphere coupling. But, without prior knowledge of other important influences on the earth’s climate, the understanding of the actual role of the sun remains incomplete. Hence, Part III covers burning issues such as greenhouse gas warming, volcanic influences, ozone depletion in the stratosphere, Arctic and Antarctic sea ice, etc. At the end of the book, there are few questions and exercises for students. This book is based on the lecture series that was delivered at the University of Oulu, Finland as part of M.Sc./ PhD module.

Hailed in the Foreign Service Journal as a landmark book that should command the attention of every serious student of American diplomacy, international environmental issues, or the art of negotiation, and cited in Nature for its worthwhile insights on the harnessing of science and diplomacy, the first edition of Ozone Diplomacy offered an insider's view of the politics, economics, science, and diplomacy involved in creating the precedent-setting treaty to protect the Earth: the 1987 Montreal Protocol on Substances That Deplete the Ozone Layer. The first edition ended with a discussion of the revisions to the protocol in 1990 and offered lessons for global diplomacy regarding the then just-maturing climate change issue. Now Richard Benedick--a principal architect and the chief U.S. negotiator of the historic treaty--expands the ozone story, bringing us to the eve of the tenth anniversary of the Montreal Protocol. He describes subsequent negotiations to deal with unexpected major scientific discoveries and important amendments adding new chemicals and accelerating the phaseout schedules. Implementing the revised treaty has forced the protocol's signatories to confront complex economic and political problems, including North-South financial and technology transfer issues, black markets for banned CFCs, revisionism, and industry's willingness and ability to develop new technologies and innovative substitutes. In his final chapter Benedick offers a new analysis applying the lessons of the ozone experience to ongoing climate change negotiations. Ozone Diplomacy has frequently been cited as the definitive book on the most successful environment treaty, and is essential reading for those concerned about the future of our planet.

A balanced assessment based on currently available scientific knowledge of the effects that climate change may have on the environment in Europe and the health of its populations. Written in non-technical language the book responds to growing public and political concern about the consequences of such widely publicized phenomena as global warming and stratospheric ozone depletion. The book also responds to evidence that recent warming trends in Europe have already affected health. The book opens with a brief explanation of the causes of climate change and stratospheric ozone depletion followed by an overview of recent European and global initiatives aimed at monitoring trends and assessing their impact on health. The first main chapter on climate change in Europe summarizes currently documented trends and provides a scenario of possible changes throughout the rest of this century. The second and most extensive chapter reviews scientific evidence on specific health consequences. These include effects related to increased episodes of thermal stress and air pollution; changes in foodborne water-related vector-borne and rodent-borne diseases; mortality from floods and other weather extremes; and changes in the production of aeroallergens associated with respiratory disorders including asthma. Chapter three considers health effects linked to stratospheric ozone depletion giving particular attention to adverse effects on the eye and immune system and skin cancer. The remaining chapters discuss health effects expected in the next decade and outline actions urgently needed in the areas of policy monitoring and surveillance and research.

Homer speaks of lightning bolts after which ‘a grim reek of sulphur bursts forth’ and the air was ‘?lled with reeking brimstone’. (Homer 3000 BC). The odour was not actually the smell of sulphur dioxide associated with burning sulphur, but rather was the ?rst recorded detection of the presence of another strong odour, that of ozone (O ) in Earth’s atmosphere. These molecules were formed by the passage of 3 lightning through the air, created by splitting the abundant molecular oxygen (O ) 2 molecules into two, followed by the addition of each of the free O atoms to another O to form the triatomic product. In fact, most of the ozone molecules present 2 in the atmosphere at any time have been made by this same two-step splitti- plus-combination process, although the initiating cause usually begins with very energetic solar ultraviolet (UV) radiation rather than lightning. Many thousands of years later, the modern history of ozone began with its synthesis in the laboratory of H. F. Schonbein in 1840 (Nolte 1999), although the positive con?rmation of its three-oxygen atom chemical formula came along sometime later. Scienti?c interest in high-altitude stratospheric ozone dates back to 1881 when Hartley measured the spectrum of ozone in the laboratory and found that its ability to absorb UV light extended only to 293nm at the long wavelength end (Hartley 1881a).
