Download or read book Between Earth and Sky written by Seth Cagin. This book was released on 1993. Available in PDF, EPUB and Kindle. Book excerpt: By the 1950s CFCs had found further applications: as propellants in aerosol spray cans, in the manufacture of Styrofoam, and as vital industrial solvents. Then, in 1974, after millions of tons of CFCs had been released into the Earth's atmosphere, two scientists at the University of California demonstrated that these same "safe" wonder substances had altered the fundamental chemistry of the atmosphere and had begun to erode the ozone layer - the protective shield of all life on earth. The battle to restrict CFCs was fought in laboratories, at international conferences, and in the halls of Congress, pitting environmentalists intent on remedying what had become a global crisis against industrialists and government officials opposed to regulation. Finally, in 1987, fifty-seven nations signed the first global environmental treaty - the Montreal Protocol, which regulated the further production of CFCs and ushered in a new era of international cooperation on the environment.

Book Synopsis Stratospheric Ozone Depletion by : Larry Parker

Download or read book Stratospheric Ozone Depletion written by Larry Parker. This book was released on 2003. 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.

Book Synopsis Protecting the Ozone Layer by : Edward A. Parson

Download or read book Protecting the Ozone Layer written by Edward A. Parson. This book was released on 2003-03-06. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first comprehensive history of international efforts to protect the ozone layer, the greatest success yet achieved in managing human impacts on the global environment. Its arguments about how this success was achieved are both theoretically novel and of great significance for the management of other global problems, particularly global climate change. The book provides an account of the ozone-depletion issues from the first attempts to develop international action in the 1970s to the mature functioning of the present international regime. It examines the parallel developments of politics and negotiations, scientific understanding and controversy, technological progress, and industry strategy that shaped the issue's development and its effective management. In addition, the book offers important new insights into how the interactions among these domains influenced the formation and adaptation of the ozone regime. Addressing the initial formation of the regime, the book argues that authoritative scientific assessments were crucial in constraining policy debates and shaping negotiated agreements. Assessments gave scientific claims an ability to change policy actors' behavior that the claims themselves, however well known and verified, lacked. Concerning subsequent adaptation of the regime, the book identifies a series of feedbacks between the periodic revision of chemical controls and the strategic responses of affected industries, which drove rapid application of new approaches to reduce ozone-depleting chemicals. These feedbacks, promoted by the regime's novel technology assessment process, allowed worldwide use of the chemicals to decline further and faster than even the boldest predictions, by nearly 95 percent within ten years.
