“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.

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.

"[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."--
