“An unnervingly close-to-home perspective [on] the dynamics and impact of climate change on plants, birds, and myriad other species, including us.”—Booklist In his meticulous notes on the natural history of Concord, Massachusetts, Henry David Thoreau records the first open flowers of highbush blueberry on May 11, 1853. If he were to look for the first blueberry flowers in Concord today, mid-May would be too late. Warming temperatures have pushed blueberry flowering three weeks earlier, and in 2012, following a period of record-breaking warmth, blueberries began flowering on April 1—six weeks earlier than in Thoreau’s time. In Walden Warming, Richard B. Primack uses Thoreau and Walden, icons of the conservation movement, to track the effects of a warming climate on Concord’s plants and animals, with the notes that Thoreau made years ago transformed from charming observations into scientific data sets. Primack finds that many wildflower species that Thoreau observed, including familiar groups such as irises, asters, and lilies, have declined in abundance or disappeared from Concord. Primack also describes how warming temperatures have altered other aspects of Thoreau’s Concord, from the dates when ice departs from Walden Pond in late winter, to the arrival of birds in the spring, to the populations of fish, salamanders, and butterflies that live in the woodlands, river meadows, and ponds. Demonstrating the effects of climate change in a unique, concrete way using this historical and literary landmark as a touchstone, Richard Primack urges us to heed the advice Thoreau offers in Walden: to live simply and wisely. In the process, we can minimize our own contributions to our warming climate.

In his meticulous notes on the natural history of Concord, Massachusetts, Henry David Thoreau records the first open flowers of highbush blueberry on May 11, 1853. If he were to look for the first blueberry flowers in Concord today, mid-May would be too late. In the 160 years since Thoreau’s writings, warming temperatures have pushed blueberry flowering three weeks earlier, and in 2012, following a winter and spring of record-breaking warmth, blueberries began flowering on April 1—six weeks earlier than in Thoreau’s time. The climate around Thoreau’s beloved Walden Pond is changing, with visible ecological consequences. In Walden Warming, Richard B. Primack uses Thoreau and Walden, icons of the conservation movement, to track the effects of a warming climate on Concord’s plants and animals. Under the attentive eyes of Primack, the notes that Thoreau made years ago are transformed from charming observations into scientific data sets. Primack finds that many wildflower species that Thoreau observed—including familiar groups such as irises, asters, and lilies—have declined in abundance or have disappeared from Concord. Primack also describes how warming temperatures have altered other aspects of Thoreau’s Concord, from the dates when ice departs from Walden Pond in late winter, to the arrival of birds in the spring, to the populations of fish, salamanders, and butterflies that live in the woodlands, river meadows, and ponds. Primack demonstrates that climate change is already here, and it is affecting not just Walden Pond but many other places in Concord and the surrounding region. Although we need to continue pressuring our political leaders to take action, Primack urges us each to heed the advice Thoreau offers in Walden: to “live simply and wisely.” In the process, we can each minimize our own contributions to our warming climate.

On the Duty of Civil Disobedience: This is Thoreau's classic protest against government's interference with individual liberty. One of the most famous essays ever written, it came to the attention of Gandhi and formed the basis for his passive resistance movement.

Archer's Global Warming: Understanding the Forecast 2nd Edition, is the first real text to present the science and policy surrounding climate change at the right level. Accompanying videos, simulations and instructional support makes it easier to build a syllabus to improve and create new material on climate change. Archer's polished writing style makes the text entertaining while the improved pedagogy helps better understand key concepts, ideas and terms. This edition has been revised and reformulated with a new chapter template of short chapter introductions, study questions at the end, and critical thinking puzzlers throughout. Also a new asset for the BCS was created that will give ideas for assignments and topics for essays and other projects. Furthermore, a number of interactive models have been built to help understand the science and systems behind the processes.

Throughout history, some books have changed the world. They have transformed the way we see ourselves - and each other. They have inspired debate, dissent, war and revolution. They have enlightened, outraged, provoked and comforted. They have enriched lives - and destroyed them. Now Penguin brings you the works of the great thinkers, pioneers, radicals and visionaries whose ideas shook civilization and helped make us who we are. Thoreau's account of his solitary and self-sufficient home in the New England woods remains an inspiration to the environmental movement - a call to his fellow men to abandon their striving, materialistic existences of 'quiet desperation' for a simple life within their means, finding spiritual truth through awareness of the sheer beauty of their surroundings.

Boldly reconfigures Walden for contemporary ethics and politics by recovering Thoreau's theological vision of environmental justice.

In 1845 Henry David Thoreau left his pencil-manufacturing business and began building a cabin on the shore of Walden Pond near Concord, Massachusetts. This lyrical yet practical-minded book is at once a record of the 26 months Thoreau spent in withdrawal from society - an account of the daily minutiae of building, planting, hunting, cooking, and, always, observing nature - and a declaration of independence from the oppressive mores of the world he left behind. Elegant, witty, and quietly searching, Walden remains the most persuasive American argument for simplicity of life clarity of conscience.When I wrote the following pages, or rather the bulk of them, I lived alone, in the woods, a mile from any neighbor, in a house which I had built myself, on the shore of Walden Pond, in Concord, Massachusetts, and earned my living by the labor of my hands only. I lived there two years and two months. At present I am a sojourner in civilized life again.I should not obtrude my affairs so much on the notice of my readers if very particular inquiries had not been made by my townsmen concerning my mode of life, which some would call impertinent, though they do not appear to me at all impertinent, but, considering the circumstances, very natural and pertinent. Some have asked what I got to eat; if I did not feel lonesome; if I was not afraid; and the like. Others have been curious to learn what portion of my income I devoted to charitable purposes; and some, who have large families, how many poor children I maintained. I will therefore ask those of my readers who feel no particular interest in me to pardon me if I undertake to answer some of these questions in this book. In most books, the I, or first person, is omitted; in this it will be retained; that, in respect to egotism, is the main difference. We commonly do not remember that it is, after all, always the first person that is speaking. I should not talk so much about myself if there were anybody else whom I knew as well. Unfortunately, I am confined to this theme by the narrowness of my experience. Moreover, I, on my side, require of every writer, first or last, a simple and sincere account of his own life, and not merely what he has heard of other men's lives; some such account as he would send to his kindred from a distant land; for if he has lived sincerely, it must have been in a distant land to me. Perhaps these pages are more particularly addressed to poor students. As for the rest of my readers, they will accept such portions as apply to them. I trust that none will stretch the seams in putting on the coat, for it may do good service to him whom it fits. I would fain say something, not so much concerning the Chinese and Sandwich Islanders as you who read these pages, who are said to live in New England; something about your condition, especially your outward condition or circumstances in this world, in this town, what it is, whether it is necessary that it be as bad as it is, whether it cannot be improved as well as not. I have travelled a good deal in Concord; and everywhere, in shops, and offices, and fields, the inhabitants have appeared to me to be doing penance in a thousand remarkable ways. What I have heard of Bramins sitting exposed to four fires and looking in the face of the sun; or hanging suspended, with their heads downward, over flames; or looking at the heavens over their shoulders "until it becomes impossible for them to resume their natural position, while from the twist of the neck nothing but liquids can pass into the stomach"; or dwelling, chained for life, at the foot of a tree; or measuring with their bodies, like caterpillars, the breadth of vast empires; or standing on one leg on the tops of pillars-even these forms of conscious penance are hardly more incredible and astonishing than the scenes which I daily witness.

"[The author] traces the full arc of Thoreau’s life, from his early days in the intellectual hothouse of Concord, when the American experiment still felt fresh and precarious, and 'America was a family affair, earned by one generation and about to pass to the next.' By the time he died in 1862, at only forty-four years of age, Thoreau had witnessed the transformation of his world from a community of farmers and artisans into a bustling, interconnected commercial nation. What did that portend for the contemplative individual and abundant, wild nature that Thoreau celebrated? Drawing on Thoreau’s copious writings, published and unpublished, [the author] presents a Thoreau vigorously alive in all his quirks and contradictions: the young man shattered by the sudden death of his brother; the ambitious Harvard College student; the ecstatic visionary who closed Walden with an account of the regenerative power of the Cosmos. We meet the man whose belief in human freedom and the value of labor made him an uncompromising abolitionist; the solitary walker who found society in nature, but also found his own nature in the society of which he was a deeply interwoven part. And, running through it all, Thoreau the passionate naturalist, who, long before the age of environmentalism, saw tragedy for future generations in the human heedlessness around him."--
