Download or read book Scientific Assessment of Ozone Depletion 2014 written by National Oceanic And Atmospheric Adminis and published by Government Printing Office. This book was released on 2017-09-08 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document is part of the information upon which the Parties to the United Nations Montreal Protocol will base their future decisions regarding ozone-depleting substances, their alternatives, and protection of the ozone layer. It is the latest in a long series of scientific assessments that have informed the Parties and contains the policy-relevant major findings of the Assessment's five scientific chapters. Actions taken under the Montreal Protocol have led to decreases in the atmospheric abundance of controlled ozone-depleting substances (ODSs), and are enabling the return of the ozone layer toward 1980 levels. This comprehensive volume includes many tables, figures, and charts throughout; and the appendices include acronyms and abbreviations, listings of authors, contributors, and reviewers from around the world, and chemical formulas.

This book was released on 2007-11-30 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Climate Change Science Program is in the process of producing 21 draft assessments that investigate changes in the Earth's climate and related systems. These assessments are designed to inform decisionmakers about the scientific underpinnings of a range of environmental issues, such as stratospheric ozone. This National Research Council report reviews one of these assessments, Synthesis and Assessment Product (SAP) 2.4, Trends in Emissions of Ozone Depletion Substances, Ozone Layer Recovery, and Implications for Ultraviolet Radiation Exposure. This assessment is noted as being the first-ever attempt to look at the United States contribution to ozone-depleting substances and ozone recovery. This National Research Council book commends the assessment's authoring team for comprehensively covering the scientific basis of ozone and ozone-depleting substances, but recommends several ways that the assessment could be improved. Suggestions include clarifying the discussion on climate effects of ozone and revising the approach to estimating U.S. contributions to production, consumption, and emission of ozone-depleting substances. The assessment could also be improved by reorganizing and editing to accommodate intended audiences.

Download or read book Stratospheric Ozone Depletion written by Larry Parker and published by Nova Publishers. This book was released on 2003 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: For two decades, scientists have been warning that chlorofluorocarbons (CFCs) and halons (bromine-containing fluorocarbons) may deplete the stratospheric ozone shield that screens out some of the Sun's harmful ultraviolet rays and thus regulates the amounts which reach the Earth's surface. CFCs have been used as refrigerants, solvents, foam blowing agents, and outside the United States, as aerosol propellants; Halons are used primarily as fire-fighting agents. Increased radiation could result in an increase in skin cancers, suppression of the human immune system, and decreased productivity of terrestrial and aquatic organisms, including some commercially important crops. This book deals with implementation, policy issues and phase out of methyl bromide. In September 1987, 47 countries (including the United States) agreed to the Montreal Protocol on Substances that Deplete the Ozone Layer, which first required controls on the world's consumption of ozone depleting substances. Over 160 countries have signed on to the Protocol, whose phasedown schedule for developed countries was accelerated twice and completely phased out Halon production at the end of 1994 and CFC production at the end of 1995. The Protocol's coverage has also been extended to include hydrochlorofluorocarbons and other chlorine- and bromine-containing substances such as some solvents and methyl bromide, a widely used soil fumigant.

Available in PDF, EPUB and Kindle. Book excerpt: 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).
