This clear and concise introduction to planetary climates explains the global physical and chemical processes that determine climate on any planet or major planetary satellite—from Mercury to Neptune and even large moons such as Saturn's Titan. The book presents a tour of our solar system's diverse planetary atmospheres, providing a rich foundation on their structure, composition, circulation, climate, and long-term evolution. Although the climates of other worlds are extremely diverse, the chemical and physical processes that shape their dynamics are the same. As this book makes clear, the better we can understand how various planetary climates formed and evolved, the better we can understand Earth's climate history and future. Explaining current knowledge, physical and chemical mechanisms, and unanswered questions, the book brings the reader to the cutting edge of this field.Less

Mercury is a global pollutant. Evidence from ice cores and lake sediments indicates that mercury deposition has increased significantly due to human activities. Most mercury is released into the environment in inorganic forms, but through methylation it is converted to organic mercury compounds. These compounds can be bioaccumulated into fish and other organisms. Mercury released into water will have regional impacts. Mercury released into the atmosphere can have regional implication, but can also be transported and deposited thousands of kilometers away. The chemistry of mercury is complex and has a strong influence on the global cycling.Less

Mercury exists in a large number of physical and chemical forms with a wide range of properties. Conversion between these forms provides the basis for mercury's complex distribution in local and global cycles and for its biological enrichment and effects. During recent years, new analytical techniques have become available that have contributed significantly to the understanding of mercury chemistry in natural systems and allow for the determination of total mercury as well as major species of mercury in water, sediments and soils, and biota. This chapter provides an overview of a wide variety of analytical methods that can be utilized, depending on the nature of the sample, the concentration levels of mercury, and what species or fraction is to be quantified.Less

As a scholar of medieval and renaissance literature, C.S. Lewis was deeply interested in the imaginative effects of the new heliocentric model of the universe theorised by Copernicus and verified by Kepler and Galileo. As a writer of fiction, Lewis held that success in imaginative composition came through suggestion rather than through statement; a good story's principal achievement was the atmosphere which it allowed the reader to inhabit, an atmosphere which should constitute the reader's mode of attention, not the reader's focus of attention. In his Chronicles of Narnia (The Lion, the Witch and the Wardrobe; Prince Caspian; The Voyage of the ‘Dawn Treader’; The Silver Chair; The Horse and his Boy; The Magician's Nephew; The Last Battle), Lewis drew upon his academic expertise in Ptolemaic astronomy and astrology, constructing each story so that it embodied and expressed the qualitative atmosphere associated with one of the seven planets of the pre‐Copernican cosmos (respectively, Jupiter; Mars; Sol; Luna; Mercury; Venus; Saturn), planets which he described as ‘spiritual symbols of permanent value’. In each Chronicle, the arc of the narrative, countless points of ornamental detail, and the portrayal of the Christological figure of Aslan, are all governed by this cosmologically based imaginative intention. The Chronicles therefore are not, first and foremost, Biblical allegories, as critics have previously assumed, but attempts to communicate seven ancient archetypes through the genre of romance. The occasioning of the first story is argued to be the famous debate at Oxford's Socratic Club in which Lewis's Christian Idealism was critiqued by the philosopher, Elizabeth Anscombe. In sum, Planet Narnia contends that the Chronicles are the product of a subtler writer and thinker than has hitherto been recognised, whose abiding interests were hiddenness, immanence, and knowledge by acquaintance.Less

This chapter reviews and compares possible causes of environmental impacts on lake and river systems in the Arctic and Antarctica, with emphasis on the direct effects of local human activities. Potential impacts fall into three broad categories: physical processes, chemical contamination, and the introduction of exotic species, including microbial contaminants. This review focuses on physical and chemical impacts. Using a range of examples, the chapter illustrates similarities and differences between the Arctic and Antarctic and identifies characteristics of high latitude lake and river systems that may influence their susceptibility to anthropogenic disturbance, including potential cumulative or synergistic effects of local disturbance during a time of rapid global change.Less

More
For many communities, exposure to mercury through fish consumption is an exemplary case of environmental injustice. Groups that rely on fishing for food, cultural identity, spiritual wellbeing, or economic prosperity are more vulnerable to mercury pollution. The vulnerability is heightened because sources and hotspots of mercury are found disproportionately in areas near communities of color, low-income and immigrant communities, and indigenous peoples. This chapter reviews cases where mercury has impacted the health, culture, and identity of local communities. Such communities are victims of environmental injustice because they have derived little or no benefit from the products and services of mercury-releasing industries, but they now bear the burden of the wastes left behind. Existing strategies for reducing mercury exposure are not always effective in communities at risk. Fish advisories that warn of health risks from eating contaminated fish themselves perpetuate environmental injustice. The shift in policy from risk reduction to risk avoidance places these communities in a lose-lose situation: either eat fish and suffer the health effects from contaminants or do not eat fish and suffer the health and cultural effects of losing a critical diet food. By allowing significant mercury contamination to remain in place while advising the population at risk to change their lifestyle, regulators are indirectly perpetuating discrimination against communities that attach different normative values to fish.Less

Persistent, bioaccumulative, and toxic (PBT) pollutants are of concern to environmental and public health policy makers because of their adverse multigenerational effects, which often range far beyond their site of initial release. PBTs, like mercury, that cause neurodevelopmental effects raise additional concerns because of their long-term individual and societal impacts, particularly on children, as well as the ethical consideration of the involuntary nature of the exposure. These attributes underpin the priority status that many states have given mercury pollution, and their focus on precautionary approaches to the issue. Mercury is also subject to atmospheric transport with both long-range and near-field deposition. Atmospheric transport creates important geopolitical policy issues for many states and countries, especially for northeastern states, where local and regional pollution reduction efforts have proven insufficient to address the impacts of many air pollutants from upwind sources. In the United States, innovative environmental policies are frequently initiated at the state level, since federal environmental statutes allow states, in most instances, to establish regulations more stringent than those adopted federally. Concerned by widespread mercury contamination and what many perceive as insufficient federal efforts to reduce mercury pollution over the past decade, the states have taken a leadership role. This chapter highlights some state-level mercury initiatives underway and the roles of science and monitoring in informing and guiding these efforts.Less

Chapter 9 explores the medical marketplace of early nineteenth‐century Britain, with particular reference to tropical invalids and others deemed to have similar complaints. The chapter focuses on the spa resort of Cheltenham which grew rapidly in the early nineteenth century to accommodate large numbers of invalids returning from the tropical colonies. Former colonial practitioners made a good living in the town and some became proprietors of spas. However, competition between them was intense because of the return of many military and naval practitioners to civilian life at the end of the Napoleonic Wars. For some observers, resorts such as Cheltenham epitomized all that was wrong with British society. They were seen as resorts for the feckless and lazy, and as the stamping‐ground of charlatans and quacks. However, they served a vital role in domesticating the Empire and offered hope to invalids returning from tropical service.Less

During the early eighteenth century, a wide range of medicines, including chemical preparations such as antimonial drugs, was being used to treat tropical complaints. During the 1750s, these were supplemented with mercury, which had hitherto been used predominantly to treat syphilis, and nitric acid, which had seldom been used in any capacity. In the hospitals of the East India Company, these substances were used widely to treat a range of complaints, including hepatitis and fever. Although the practice initially faced great opposition from physicians in Britain, mercury in the form of calomel soon came to be used throughout the British Empire. The same was true for a time of nitric acid, which was endorsed by senior figures in the British Army, as well as by reform‐minded civilian practitioners who saw chemical therapeutics as the key to medical progress.Less

In the early years of the nineteenth century, medical practice in Britain's colonies changed radically. Having been marginalized in tropical therapeutics since the 1750s, bleeding now began to replace the mercurial therapies that had dominated the previous half‐century. Starting in the West Indies, under the influence of Robert Jackson, and continuing in India under the direction of James Johnson, among others, bloodletting, often combined with ‘stimulant’ practices such as cold bathing, made a remarkable come‐back. The revival of bloodletting depended largely upon the growing acceptance of nervous physiology and the decline of notions of putrefaction. However, it was accompanied by growing interest in the practices of the radical Edinburgh practitioner John Brown which harmonized with the reformist worldview of many practitioners in the tropics, including the turbulent ‘demagogue’ Charles Maclean. In their practices, there remained a role for mercury as a nervous stimulant, together with other substances such as opium.Less

This chapter presents two examples of irreversible proportional disease processes. The first example, the neurobehavioral effects of mercury, is relatively well studied, with a long and tragic history. The second example is much more recent, and there remain many uncertainties about the causal mechanisms by which a recently identified lung toxin — the artificial butter flavoring in microwave popcorn — leads to severe lung disease.Less

This chapter focuses on the 10th-century Cologne copy of Martianus Capella's Marriage of Mercury and Philology (Ms. 193), particularly of interest along the Platonist lines of the unity of creation and human ethics. Martianus Capella was an African contemporary of Augustine of Hippo, but probably a pagan. His work is in nine books, the last seven of which form a treatise on each of the seven liberal arts (the trivium of grammar, dialectic, and rhetoric; the quadrivium of arithmetic, geometry, astronomy, and music).Less

The Mercury perihelion problem: A proposal to alter the inverse-square law ruled out by a more precise measurement. Einstein’s theory accounts for the extra precession and recovers the successful measurements of Newton’s theory. An alternative to general relativity that would answer a new challenge from Mercury is ruled out by a more precise measurement. Part III. Newton does not require or endorse scientific progress as progress toward Laplace’s ideal limit of a final theory. Part IV. Newton’s conception of scientific progress through successively more accurate approximations is not undermined by the classic argument against convergent realism. Part V: Agreeing measurements from diverse phenomena play a decisive role of in transforming dark energy from a dubious hypothesis into part of the accepted background framework guiding empirical research in cosmology today.Less

The historiography of Hispano-United States relations during the Cold War has been dominated for the past thirty years by studies of the latter's negotiations for, and signing of, base agreements with Spain in September 1953. In the post-Cold War era, the significance of the 1953 agreements lies as much in the light that they cast on Spain's role in the global rivalry between Western powers, and shifting power patterns, as in the impact these had on Spain itself. Striking differences in attitude of the United States and Britain towards Spain illuminate their changing roles in the Western Mediterranean, as the gateway to the Middle East to which the Straits of Gibraltar were the key. The question of the western Mediterranean was always closely bound to Spain's Iberian neighbours, Gibraltar and Portugal. The Rock of Gibraltar was the fortress which had long ensured Britain's access to the Mediterranean. Aside from its celebrated rich resources of mercury, copper, and other minerals, the Spanish potential for uranium bearing ores was also of interest to other countries.Less

This chapter examines the visual performance of Amazonian gold miners and other workers suffering from mercury poisoning. Subjects exposed to mercury displayed a variable degree of spatial vision dysfunction. Both achromatic and chromatic vision were impaired. They had lower achromatic contrast sensitivity and this effect was more pronounced in the medium spatial frequency range. Mercury exposed subjects also had lower red-green and blue-green chromatic contrast sensitivity than control subjects in all tested spatial frequencies.Less

Mencken believed that the Constitution and Bill of Rights were sacred documents that set clear lines of demarcation that no government should trespass. “The two main ideas that run through all of my writing”, he said, “whether it be literary criticism or political polemic, are these: I am strongly in favor of liberty and I hate fraud”. Freedom had always been an issue with Mencken: first, freedom from his father's choice of a career; later, as he developed as a critic, from the Victorian Puritanism that stifled American life; then, from governmental laws that violated civil liberties for whites and blacks; and finally, during the two world wars, freedom from censorship of the press.Less

This chapter picks up from the opening scene described in the Prologue of this book, when the April 1926 issue of The American Mercury was banned in Boston and Mencken was arrested. Mencken became disillusioned when his fight against censorship was criticized by fellow journalists as being a mere publicity stunt, even though his efforts cleared the way for journalists and publishers to publish whatever they want. Worldwide, Mencken's name became forever identified with freedom of speech.Less

The situation of The American Mercury did not improve during the Depression, and brought Alfred Knopf; his father, Samuel; and Mencken at a crossroads. Samuel Knopf wanted Mencken to expand the magazine along his own editorial lines; Mencken balked. A new generation of college students derided him; critics said that Mencken's columns aroused as much controversy as the weatherman. At this juncture, George Jean Nathan wrote his memoirs, Friends of Mine, and his disloyalty put an end to their troubled friendship.Less
