Book Description
A leading authority in the field takes readers on a fascinating and surprising journey through the atmosphere—from our lungs to outer space—that will leave readers breathless. With seven million early deaths each year linked to air pollution, air quality is headline news around the world. But even though we breathe in and out every few seconds, few of us really know what’s in the air all around us. In Every Breath You Take, air quality specialist—and full-time breather—Dr. Mark Broom connects the dots from the atmosphere on distant planets to the holes in the ozone layer to the particles in our lungs. How do we measure air pollution and what on earth is an odor panel? Why are property prices higher upwind of cities? And will our grandchildren inherit an atmosphere worth breathing? With keen insights on the atmospheric effects of climate change, industrial air pollution, and urbanization in the twenty-first century, Every Breath You Take combines the latest scientific research with Mark’s personal stories to answer these questions and many more in a readable and surprising journey through the atmosphere.

Book Description
Arctic haze is the phenomenon of large-scale industrial air pollution found all through the arctic air mass. Vertical profiles of air concentrations, obtained during several aircraft measurement programs in the Arctic, have offered the following explanation of arctic haze origin. Very long range, episodic transport of air masses over several thousand kilometers clearly affects the quality of arctic air during both summer and winter. Polluted air masses, carrying a mixture of anthropogenic and natural pollutants from a variety of sources in different geographical areas have been identified in the arctic atmosphere at altitudes from 2 to 4 or 5 km. The layers of polluted air at altitudes below 2.5 km can be traced to episodic transport of air masses from anthropogenic sources situated closer to the Arctic. Pollution material in arctic haze is of submicron size and contains a substantial fraction of black carbon: it interacts strongly with solar radiation. In addition, sulfate and a wide range of heavy metals appear, affecting their natural geochemical cycles. They also serve as indicators of major source regions of emissions in the world. This paper discusses what happens to the haze-related pollutants in the Arctic, what is the contribution of natural sources to the arctic haze and what are local and global effects of arctic haze. Some indications are given of the research to be undertaken in a view to assess the role of the Arctic in global change of the environment.

Book Description
This timely book presents a wide-ranging review of Arctic environmental change in response to global warming, and gives a broad insight into the transformation of the Arctic which we can expect during the next century. It is in high northern latitudes that we can expect to observe global warming at its most powerful, making it a natural laboratory where climate changes and their impacts can be monitored and studied more readily than elsewhere in the world. Fourteen authoritative reviews cover the predictions of warming rates by General Circulation Models; variabilities in atmospheric circulation and moisture flux; the dynamics of the polar vortex in the Arctic and its role in ozone loss; the countervailing influence of air pollution in reducing solar irradiance; and the impact of climatic change on Arctic terrestrial and marine ecosystems. Also detailed are the thermohaline circulation of the ocean, the extent and thickness of sea ice, the sizes of glaciers and ice sheets, and the extent of permafrost. Moving to past changes, the records from Greenland ice cores and deep ocean drilling are reviewed for what they tell us about past climates and glaciation in the Arctic., The book paints a vivid and disturbing picture of the enhanced warming that can be expected in the Arctic relative to lower latitudes, and of the major impacts that this will have on the northern cryosphere. It will be an invaluable reference for anyone seeking a greater understanding of the factors and processes affecting the arctic environment, which may ultimately have a major impact on global climatic change.

Book Description
Arctic atmospheric pollution is now a major international issue. This volume presents the most authoritative review of this increasingly important subject for an audience of both scientists and administrators concerned with worldwide, as well as polar, pollution problems. Arctic Air Pollution is an edited collection of papers, first presented at a conference helo as the Scott Polar Research Institute in Cambridge in 1985. Building on foundations established at earlier meetings, this volume examines the problem of Arctic air pollution in an integrated, multidisciplinary fashion, with contributions from leading authorities in chemistry, ecology, climatology and epidemiology. To chemists, physicists and climatologists, it presents scientific problems. Ecologists are concerned with environmental threats; medical researchers with potential threats to human health. International lawyers and administrators are concerned with the legal implications of pollutants transferred across continents. Overall hangs the major question; can man-made pollution affect the delicate energy balance of the Arctic, and precipitate major climatic change worldwide?

Book Description
Second national state-of-the-environment report, addressing the questions of what is happening in Canada's environment, why it is happening, why it is significant, and what Canadians are doing about it. The report is divided into five parts, dealing with perceptions of the environment and the dangers inherent in our tendency to look at the world in terms of human economic models; exploring the state of particular environmental components and the major sectors of human activity; describing six regional case studies; addressing six important environmental issues; and discussing the concept of sustainable development and its implications for Canada's future.
